NAMMCO Annual Report 2007 - 2008

1.1 REPORT OF THE SEVENTEENTH MEETING OF COUNCIL 2-4 September 2008, Sisimiut, Greenland

1. OPENING PROCEDURES

The Chair of the Council, Kate Sanderson (Faroe Islands) opened the meeting at Taseralik, the Sisimiut Cultural House, and welcomed all delegates and observers. The list of participants is contained in Section 5.1.

In her opening remarks, the Chair noted that it had been 18 months since the last Annual Meeting but that there had been no shortage of activities in the interim period, not least of which was the successful planning and implementation of T-NASS. She welcomed in particular the new Scientific Secretary, Mario Acquarone as a valuable addition to the Secretariat. He had taken up his position in April last year and was now attending his first annual meeting. On behalf of all participants the Chair thanked the Government of Greenland for hosting the meeting in the beautiful surroundings of Sisimiut.

1.1 Welcome address Mr Finn Karlsen, the Minister for Hunting, Fisheries and Agriculture of Greenland welcomed the 17th Annual Meeting of NAMMCO to Sisimiut, Greenland. The text of Mr Karlsen’s welcome address is contained in Appendix 3.

1.2 Opening statements Opening statements were made by the Faroe Islands, Iceland and Norway and a written statement was submitted by Japan. These are contained in Appendix 3.

1.3 Admission of Observers Observers from Canada, Denmark, Japan and Russia, North East Atlantic Fisheries Commission (NEAFC), Northwest Atlantic Fisheries Organization (NAFO), International Whaling Commission (IWC), and several Non-Governmental Organisations - Inuit Circumpolar Council (ICC) and High North Alliance (HNA) were welcomed. Apologies were received from St Lucia, International Council for Exploration of the Sea (ICES), Food and Agriculture Organization (FAO), North Atlantic Salmon Commission (NASCO) and European Bureau for Conservation and Development (EBCD) and the Swedish Association for Hunting and Wildlife Management.

1.4 Invited Speaker Peder Olsen, Chairman of KNAPK, the Greenland Hunters’ and Fishermen’s Association, gave a presentation entitled “Sealing and whaling in Greenland”. The presentation is summarised in Appendix 4.

Commenting on the presentation and opening statements, Minister Karlsen of Greenland expressed his appreciation that KNAPK, Faroe Islands, Iceland and Norway all share the same views on the importance of ensuring sustainable use of 11

Report of the Council marine mammals, and that NAMMCO is fully mandated to manage all marine mammals, including large whales.

1.5 Adoption of agenda The final draft agenda was adopted without amendments (Appendix 1).

1.6 Meeting arrangements Social arrangements during the meeting included a reception on Monday 1 September at Taseralik, hosted by the Municipality of Sisimiut and a dinner at Hotel Sisimiut on Wednesday 2 September hosted by the Greenland Ministry of Hunting, Fisheries and Agriculture.

2. FINANCE AND ADMINISTRATION

2.1 Report of the Finance and Administration Committee The report of the Finance and Administration Committee (NAMMCO/17/4) was presented by the Chair of the Committee, Ásta Einarsdottír (Iceland).

It was noted that the final accounts for the 2007 had been adopted by the Council earlier in the year (see Appendix 5).

The Council endorsed the recommendations and conclusions of the Finance and Administration Committee related to the staff employment survey (review of salary scales and pension), rates for observers under the NAMMCO Observation Scheme, and the status of locally recruited staff in the official category in relation to the Host Agreement.

The Chair noted that adaptation of the salary scheme for Secretariat staff to a UN- based system was a priority issue for the Council in the coming months.

2.2 Commission Draft Budget 2009 The Council adopted the draft Budget for 2009 as contained in NAMMCO/17/4, Annex 1, with a minor increase under the budget item other expenses. The final amended budget and breakdown of membership contributions for 2009 would be circulated immediately after the meeting.

3. SCIENTIFIC COMMITTEE

3.1 Report of the Scientific Committee The Chair of the Scientific Committee, Geneviève Desportes (Faroe Islands) presented the Report of the Scientific Committee (NAMMCO/17/5; Section 3.1).

The presentation of detailed advice on specific stocks and species was referred to the relevant Management Committees. The Scientific Committee Chair therefore focussed her presentation on advice on items common to stocks and species, such as T-NASS (see under Item 3.2), marine mammal fisheries interactions, by-catch, as well as organisational and procedural matters in the work of the Scientific Committee. 12

NAMMCO Annual Report 2007 - 2008

Participation and data presentation in the Scientific Committee The Scientific Committee Chair noted that there was not always full participation of all appointed members, which is problematic for such a small Committee. In addition, some documents presenting data resulting from work coordinated through NAMMCO had not been presented to the Scientific Committee before being dealt with in other bodies.

The Council urged member countries to ensure that their appointed members to the Scientific Committee were in full attendance at Scientific Committee meetings, or where this is not possible, to appoint alternative members with the relevant expertise to address the specific issues being dealt with by the Scientific Committee at any given time. The Council also stressed the importance of having all relevant data presented to the NAMMCO Scientific Committee in a timely fashion to enable it to address fully the requests for advice forwarded from the Council and urged member countries to ensure that this was followed up on a national basis.

The Council reiterated its wish that endorsement of abundance estimates by the Scientific Committee only be carried out on the recommendation of either the NAMMCO Working Group on Abundance Estimates or a NAMMCO Assessment Working Group, in order to provide for the possibility of using the most competent expertise, both internal and external.

Proposed work plan of the Scientific Committee The Council noted the proposed work plan of the Scientific Committee (NAMMCO/17/5; Section 3.1) with working groups and workshops scheduled or proposed for 2009 and 2010 to address outstanding requests for advice and assessments, including work to finalise new abundance estimates for several cetacean species after T-NASS. This proposed work was also considered in more detail by the respective Management Committees.

The Council endorsed the Scientific Committee’s proposed work plan, but noted that the priority of tasks would need to be further clarified after discussions in the Management Committees and in the light of new requests resulting from their deliberations (see Items 5.2 and 6.2).

NAMMCO Scientific Publication Series With respect to the NAMMCO Scientific Publication series, the Grey Seal volume was produced in late 2007, and the NASS volume is scheduled to be finalised before the end of 2008. The volume on Harbour Seals is well under way and is expected to be published in 2009.

The Scientific Committee sought guidance from the Council on the publication of results and analysis of T-NASS. The Scientific Committee recommended a joint publication with the IWC Scientific Publication series, and the Secretariat had already made informal enquires to the IWC Secretariat on this possibility. In response, the Council noted the importance of highlighting the leading role of 13

Report of the Council

NAMMCO in the planning and implementation of T-NASS, underlining that this role should be quite clear in the subsequent publication of data resulting from T-NASS. Although it would be preferable to publish T-NASS results as a stand-alone volume of the NAMMCO Scientific Publication series, it was also noted that timing and editing issues suggest that co-publication with the IWC was likely to be a more effective approach for the dissemination of the material.

The Council therefore agreed that a joint NAMMCO/IWC publication on T-NASS should be pursued.

3.2 Trans-North Atlantic Sightings Survey - T-NASS 2007 The Scientific Committee Chair, Geneviève Desportes, who was also the T-NASS coordinator on behalf of NAMMCO, summarised the report of the T-NASS WG (NAMMCO/17/5 Annexes 1.1, 1.2 and 1.3; Section 4.1) and the outstanding tasks still to be completed. T-NASS was the culmination of previous requests to the Scientific Committee (NAMMCO/13, 14 and 16) and the third such North Atlantic cetacean sightings survey coordinated by NAMMCO (after NASS 1995 and NASS 2001). Non- member countries were encouraged to participate to achieve the broadest coverage possible. Fin, minke and pilot whales were priority species, but the methodology should also accommodate the need for estimates for harbour porpoises especially in Icelandic waters. Estimates and trends of abundance should be produced as soon as possible after completion of the survey programme.

T-NASS had indeed achieved a trans-Atlantic coverage, which had been the aim since the beginning of the NASS surveys. NAMMCO achieved also “value for money” from the T-NASS project. Observers were placed on board other platforms of opportunity, conducting non-whale surveys concomitantly to T-NASS in contiguous areas, thus broadening the coverage. Besides the sightings survey, a methodology adequate for deep-diving species, such as sperm whales, was used from the survey vessels. The involvement of PINRO in Russia should contribute to insuring a compatibility of methodology, and thus abundance estimates, in adjacent areas.

Desportes noted in summary that the synoptic coordinated trans-North Atlantic survey was effectively implemented, and although national priorities are somewhat different, all NAMMCO member countries, the Faroe Islands, Greenland, Iceland and Norway participated and contributed. Also Canada and Russia participated for the first time, thus laying the foundations of a trans-North Atlantic survey spanning from the to the eastern Canadian coast. Opportunistic surveys using ICES Redfish, MAR- ECO and pelagic Norwegian-Russian surveys were undertaken. Timing of the survey was centred in July, although Greenland conducted its main effort in September. The Norway dedicated survey area was unfortunately not contiguous with the other dedicated surveys, although the opportunistic surveys conducted from the two Norwegian vessels involved in the Norwegian-Russian pelagic survey provided a continuity. The Canadian survey in the central Davis Strait had to be cancelled, but the continuity between east and west was insured by the opportunistic survey conducted from the Russian ICES redfish platform.

14

NAMMCO Annual Report 2007 - 2008

For the first time as well, a NASS survey co-operated with a European – CODA – and an American – SNESSA – concomitant survey, insuring a co-ordinated effort. The broadest synoptic coverage possible was thus achieved with T-NASS, of which the12 dedicated platforms covered 57,781 nm in effort. With the associated surveys included, the total coverage was 71,332 nm.

The fact that the survey was a large synoptic international survey had been crucial in securing funding, at least for the Canadian surveys. However, funds are still needed for some of the analyses. The new cooperation established between the three programmes, and with other non-cetacean programmes, is very valuable. SNESSA, CODA and NAMMCO have agreed to publish as a priority a joint primary publication pertaining to the general distribution of all cetacean species throughout the entire survey area, under the leadership of the T-NASS coordinator and the NAMMCO Secretariat. Finally, the Scientific Committee also recommends that archive data be stored at the NAMMCO Secretariat for future reference.

Abundance estimates are being produced, some of them have already been reviewed by the Scientific Committee, and in the case of the Icelandic coastal minke whale the abundance estimate was endorsed. Estimates for the target species will be reviewed by the NAMMCO ‘fin - large whale’ assessment Working Group which will meet in early spring 2009 (fin, humpback, sei, minke and pilot whales estimates). Most of the other analyses are planned to be completed by the end of 2009.

The Council applauded Geneviève Desportes for her tireless and professional efforts as T-NASS coordinator, also acknowledging the excellent support of the Secretariat.

The Council commended T-NASS as a flagship for NAMMCO and a unique achievement, having provided a much broader coverage than any previous cetacean sightings survey, either in the North Atlantic or in any other region. Areas that had never been covered before or not at the same time as other areas had now been covered. The success of the T-NASS was also due to excellent working relationships with other organisations and research institutes in non-member countries across the North Atlantic. The Council saw the cooperation established between SNESSA, CODA and NAMMCO as very valuable and regarded the joint publication on cetacean distribution as a priority and urged member countries to ensure that the necessary data be provided in a timely fashion to the Secretariat.

The Council noted that changing ecosystems require regular good quality surveys of baseline abundance and distribution, and highlighted the importance of developing updated abundance estimates for the target species as soon as possible, noting that most results will be available in 2009.

A representative from KNAPK (the Greenland Hunters’ and Fishermen’s Association) commented that more minke whales have been observed recently north of Disko Bay and Melville Bay than have been seen before, while no minke whales had been observed in the south, indicating a possible migration north. He suggested that this northern area should therefore be covered in future surveys. (See also Item 4.4 of the 15

Report of the Council

Management Committee for Cetaceans report, Section 2.1.)

Other matters arising from T-NASS related to the conservation and management of specific cetacean species and stocks were referred to the Management Committee for Cetaceans.

3.3 Rules of Procedure The Scientific Committee Chair drew attention to the proposed revision to the Scientific Committee’s Rules of Procedure to extend the Chair’s term from 2 to 3 years in order to provide for better continuity and long-term planning in the work of the Scientific Committee.

The Council approved the proposed revision of the Scientific Committee Rules of Procedures, Article II, paragraph 2 which would now read: The Scientific Committee shall elect by majority vote from amongst its members a Chairman and a Vice- Chairman. The Chairman and vice-Chairman shall serve for three years...... ”.

Geneviève Desportes would therefore serve as Scientific Committee chair for one more year, and the Council welcomed her continuation.

4. NATIONAL PROGRESS REPORTS

National Progress Reports were submitted by all member nations. The Council noted with appreciation the submission of a National Progress Report from Canada, and thanked Russia and Japan for submitting comprehensive reports of their marine mammal research to the Scientific Committee. These documents were also circulated as Council documents for general information. The Chair proposed that questions related to the specific contents of the National Progress Reports should be taken up in the relevant Management Committees.

5. MANAGEMENT COMMITTEE FOR CETACEANS

5.1 Report of the Management Committee for Cetaceans The Report of the Management Committee for Cetaceans (NAMMCO/17/6; Section 2.1) was presented by its Chair, Halvard P. Johansen (Norway).

Species / Stocks The Council noted the deliberations of the Committee with respect to species and stocks of whales of interest to member countries. The Management Committee for Cetaceans Chair reported to the Council on the proposals for conservation and management agreed for stocks of cetaceans in the North Atlantic (See also Item 4. of the Management Committee for Cetaceans report, Section 2.1.)

The Council also noted the deliberations of the joint session of the Management Committee for Cetaceans and Management Committee for Seals and Walruses (Item 6. in the report of the Management Committee for Cetaceans, Section 2.1) to discuss conservation and management related issues of overlapping interest, including marine 16

NAMMCO Annual Report 2007 - 2008 mammal fisheries interactions, environmental issues, by-catch and users knowledge in management decision-making.

The Council also took note of the recommendations for further research identified by the Scientific Committee and endorsed by the Management Committee for Cetaceans, noting that these recommendations are directed to individual member countries for appropriate action (see the report of the Management Committee for Cetaceans, Section 2.1, Appendix 5).

5.2 Requests for advice from the Scientific Committee The Council agreed to forward the following requests for advice to the Scientific Committee, as recommended by the Management Committee for Cetaceans:

Narwhal and Beluga The Scientific Committee is requested to update the assessment of both narwhal and beluga, noting that new data warrant such an exercise. The NAMMCO Scientific Committee/JCNB Joint Working Group should meet before March 2009, to allow the updated assessment to be available for setting the new quota series. Greenland should submit fully corrected estimates derived from the 2006, 2007 and 2008 surveys to the joint Working Group. In addition, as in 2006, advice should also be forwarded to the Canada/Greenland Joint Commission on Conservation and Management of Narwhal and Beluga (JCNB).

Fin whales The Scientific Committee is requested to complete an assessment of fin whales in the North Atlantic and also to include an estimation of sustainable catch levels in the Central North Atlantic. This work should be initiated as soon as all estimates become available and before the next meeting of the Scientific Committee.

Minke whales The Scientific Committee is requested to conduct a full assessment, including long-term sustainability of catches, of common minke whales in the Central North Atlantic once results from the 2009 survey become available. In the meantime the Scientific Committee is requested to assess the short-term (2-5 year) effects of the following total annual catches: 0, 100, 200, 400.

Sei whales The Scientific Committee is requested to review the new data from T-NASS and associated surveys and report on the status of sei whales through the Fin Whale assessment WG.

Humpback whales The Scientific Committee is requested to assess the long-term effects of catches of 0, 2, 5, 10, 20 humpback whales off West Greenland and estimate sustainable yields for other stocks, as well as to conduct a formal assessment following the completion of the T-NASS. In addition, the relationship between the humpback whales summering in West Greenland and other areas should be investigated and this knowledge 17

Report of the Council incorporated into the estimate of sustainable yields of West Greenland humpback whales.

Management models for baleen whales The Scientific Committee is requested to study general models for conservation and management of baleen whales, inter alia based on Norwegian studies presented to the Scientific Committee of the IWC.

Role of Marine Mammals in the Ecosystem In addressing the standing requests on ecosystem modeling and marine mammal fisheries interaction, the Scientific Committee is requested to extend the focus to include all areas under NAMMCO jurisdiction. In the light of the distributional shifts seen under T-NASS 2007, the Scientific Committee should investigate dynamic changes in spatial distribution due to ecosystem changes and functional responses.

5.3 Other business The Council welcomed the election of Ásta Einarsdóttir as Chair and Ulla S. Wang as Vice-Chair of the Management Committee on Cetaceans for the period 2008-2010.

6. MANAGEMENT COMMITTEE FOR SEALS AND WALRUSES

6.1 Report of the Management Committee for Seals and Walrus The Report of the Management Committee for Seals and Walruses (NAMMCO/17/7; Section 2.2) was presented by its Chair, Amalie Jessen (Greenland).

Species / Stocks The Council noted the deliberations of the Committee with respect to species and stocks of seals and walruses of interest to member countries. The Management Committee for Seals and Walruses Chair reported to the Council that there were no new proposals for conservation and management agreed for stocks of seals and walruses in the North Atlantic (see also Item 4. of the Management Committee for Seals and Walruses report, Section 2.2).

The Council also took note of the recommendations for further research identified by the Scientific Committee and endorsed by the Management Committee for Seals and Walruses, noting that these recommendations are directed to individual member countries for appropriate action (see the report of the Management Committee for Seals and Walruses, Section 2.2, Appendix 3).

6.2 Recommendations for requests for advice The Council agreed to forward the following requests for advice to the Scientific Committee, as recommended by the Management Committee for Seals and Walruses:

Harp seals The Scientific Committee is requested to provide advice on Total Allowable Catches for the management of this species and the establishment of a quota system for the common stocks between Norway and the Russian Federation, leaving full freedom to 18

NAMMCO Annual Report 2007 - 2008 the Committee to decide on the best methods to determine this parameter based on an ecosystem approach.

The Council noted the importance for the study of harp seal ecology that satellite tags can be deployed in the White and Barents Sea in 2009 and encouraged the Russian authorities to allow the continuation of this study.

6.3 Any other business The Council took note of discussions in the Management Committee on Seals and Walruses related to trade bans against seal products. Although NAMMCO does not deal formally with trade issues, all Council members shared concerns that moves within the European Union to impose import bans on seal products can have serious implications for the responsible management and sustainable utilisation of abundant seal stocks across the North Atlantic, and for the economies of the many communities dependent on these valuable resources.

The Council noted that such import bans were not being proposed due to any concerns about the conservation status of seal stocks in the North Atlantic. Rather, they appear to have their basis in discussions related to hunting methods (see reports from ESFA and COWI under the auspices of the European Commission), which are unfortunately very often confounded by misleading and inaccurate depictions of sealing practices publicised throughout the media.

It was nevertheless noted that there appears to be a growing understanding in many countries that seal stocks are legitimate and abundant resources. This was a major focus of the International Conference “Seals and society – how to manage resources and interactions in the Baltic Sea and North Atlantic”, held in Vaasa, Finland in October 2007. The importance of seals as resources was also clearly underlined in the declaration “Seals and Society” adopted by the Nordic Fisheries Ministers at their meeting in Växjö, Sweden on 26 June 2008. The Council welcomed these developments.

7. HUNTING METHODS

7.1 Report of the Committee on Hunting Methods The Report of the Committee on Hunting Methods (NAMMCO/17/8; Section 1.2) was presented by its Chair, Egil Ole Øen. (Norway).

Workshop plans - Handling, processing and utilisation of hunted marine mammals The Council expressed it support for the on-going planning of the Committee for the proposed workshop on handling, processing and utilisation of hunted marine mammals, which is now scheduled for November 2009, with Sandefjord, Norway as a suggested venue. Seals, whales and walruses should be included in the workshop discussions. Hunters will be the main participants, as well as researchers and representatives from all relevant countries where whaling and sealing is conducted. It was also noted that

19

Report of the Council input from food safety and hygiene experts and authorities would also be important for the workshop.

New developments in member countries With regard to the reported new instrument for use in killing pilot whale, the Faroe Islands informed the Council that the a spinal lance is not yet in general use but has great potential as an efficient new tool, noting that it has been developed on the initiative of experienced whalers. The Faroe Islands also informed the Council that a full revision of the 1998 executive order on pilot whaling is planned, which will adapt the regulations to take account of new developments in equipment and other matters related to the organisation and division of whale catches.

The Council also noted the information from Greenland, reviewed by the Hunting Methods Committee, that that a quota of 2 bowhead whales was allocated for 2009. Plans are to use a grenade cannon as is used in the hunting of fin whales. The Hunting Methods Committee provided Greenland with advice on the best targeting methods, recommended a 3-year year trial period in which methods could be developed and agreed that it would be important to identify a small number of vessels (2 – 3) with a license to hunt the quota under monitored and controlled circumstances and thus gain the necessary experience to adapt the best possible hunting methods.

Best practices in sealing With reference to the Hunting Committee suggestion for how to proceed with the requested work to focus on best practices in sealing (NAMMCO/17/8, Item 7.1; Section 1.2), the Council confirmed the following work plan and terms of reference: • The work should build upon the knowledge and experiences already gathered in previous workshops organised by the Committee and possible new developments emerging since the last workshop held in 2006. • The work should be undertaken in a focussed group of specially invited experts with experience in seal hunting practices from sealing nations and communities. • The expert group will critically assess different seal hunting methods within their contexts, addressing such questions as: ° The use of specific hunting methods and equipment in particular settings ° Training requirements for hunters ° Control and monitoring of hunting methods ° Research needs to improve the basis for further assessment. • The expert group will develop recommendations on best practices based on state of the art in sealing today and identify where and how specific improvements can be made. • As background information for the work of the expert group, the Secretariat, in cooperation with the Hunting Methods Committee, will prepare a collation of relevant information and recommendations on seal hunting methods from previous NAMMCO workshops and other relevant and up-to-date sources of information on sealing practices. 20

NAMMCO Annual Report 2007 - 2008

It is expected that the expert group will convene in the spring of 2009 and its conclusions will be presented to the Council at its next annual meeting.

7.2 Other business Council members agreed with comments by Greenland that the work of the Committee on Hunting Methods should be publicised. The Council endorsed Greenland’s suggestion that efforts be made to disseminate the work of the Committee and its workshops more widely. The focus should be on the valuable exchange of expertise and information between hunters and technical experts through NAMMCO, which aims to ensure the best possible humane killing methods in different forms of whaling, sealing and walrus hunting.

The observer from Japan informed the Council that Japan’s intention is to send whale killing data and information to NAMMCO. Japan has suspended submission of data on hunting methods to the IWC and has informed that organisation that Japan will submit data to NAMMCO. The Chair thanked Japan and underlined that relevant data submitted by Japan was always very welcome.

8. THE JOINT NAMMCO CONTROL SCHEME

8.1 Report of the Committee on Inspection and Observation The Chair of the Committee on Inspection and Observation, Ole Heinrich (Greenland), presented the Report of the Committee (NAMMCO/17/9; Section 1.3).

The Committee on Inspection and Observation has over the past year been working on the Council’s request to revise the provisions of the Joint NAMMCO Control Scheme in order to integrate requirements for observer training to ensure observer safety onboard vessels, and to take account of recent technological developments in automated monitoring. A draft revision of the provisions of the Scheme was under consideration by members of the Committee, but it had not been possible to finalise its text prior to the Council meeting.

The Council therefore agreed to defer the issue until next year, but requested the Secretariat to circulate the most recent draft revision to heads of delegations for information. The Committee was asked to finalise the revision as soon as possible and to ensure that the provisions are fully up-to-date and do not have to be revisited too frequently. It was also underlined that the existing provisions are certainly still an adequate basis for observation activities in the coming year.

8.2 NAMMCO International Observation Scheme 2007 and 2008 The report on the implementation of the NAMMCO International Observation Scheme in 2007 and 2008 (NAMMCO/17/10; Section 1.4) was presented by the Deputy Secretary Charlotte Winsnes. In 2007, a NAMMCO observer was stationed in the Faroe Islands and observed a catch of 231 pilot whales in August. In 2008, a NAMMCO observer was on board a sealing vessel in Norway and observed a total of 397 seals hunted. No violations were observed in either year and observers reported and carried out their work according to the provisions of the Scheme. 21

Report of the Council

In response to general comments from the Secretariat regarding the logistical challenges associated with placing NAMMCO observers in the field, sometimes at very short notice, the Council agreed that all efforts possible should be made by national authorities to provide the Scheme with a larger pool of suitably qualified people as official NAMMCO observers.

9. ECOSYSTEM-BASED MANAGEMENT

The Chair recalled that at NAMMCO/16 it had been decided to transfer this agenda item from the former General Management Committee to the Council agenda for future meetings to avoid duplication of discussions. At the same time it was noted that this item could still be considered with regard to the specific conservation and management focus of the respective Management Committees.

A substantive discussion on the subject of Ecosystem-based Management took place in 2006 in the former General Management Committee, based on the report of the ad hoc Working Group on enhancing Ecosystem-Based Management, which had met in September 2005. A number of recommendations were made for follow up discussions and the ad hoc Working Group was requested to meet inter-sessionally. However, this group had not met since 2005.

The Chair pointed out that the Council now needed to make a decision on how it wished to deal with this issue as a general item on its own agenda. The Chair reminded delegations that NAMMCO has, since its inception, recognised the need for ecosystem approaches to management. Requests for advice from the Scientific Committee also focus on developing a better understanding of the relationship between marine mammals and other marine living resources, and the impact of environmental factors. These and other related issues were also items on the agendas of both the Management Committees (Cetaceans and Seals and Walruses), and a joint session of both Committees had dealt with these matters (Items 6.1, 6.2 and 6.3 in the report of the Management Committee for Cetaceans, Section 2.1).

It was noted that the development of ecosystem models for use in management was a time-consuming process, but that enough progress had been made in this area recently to warrant new consideration and a broader terms of reference in the Scientific Committee Working Group on marine mammal-fisheries interactions (see Item 5.2 above).

The Council also welcomed the report from the NAMMCO observer who had taken part in the FAO ecosystem modelling workshop in Rome in 2007 (NAMMCO/17-12-INFO 2).

In summary it was noted that the Scientific Committee has new work planned in the near future and the Management Committees for Cetaceans and Seals and Walruses have ecosystem-related issues on their agendas in order to relate new scientific knowledge to conservation and management recommendations.

Given this, the Council decided to discontinue the ad hoc Working Group on ecosystem- 22

NAMMCO Annual Report 2007 - 2008 based management. It was stressed that discussions of a general nature on the management level in recent years had been useful, and the efforts of the members of the ad hoc Working Group were appreciated. However, the continued scientific and management focus on these issues was more appropriate for detailed discussion in the respective Management Committees. It was however also agreed to keep this item on the Council agenda as an opportunity to follow developments in more general terms and to review how other relevant international bodies are addressing both the concepts and the practicalities of ecosystem-based management.

10. USER KNOWLEDGE IN MANAGEMENT DECISION -MAKING

The Chair recalled that at NAMMCO/16 it had been decided to transfer this agenda item from the former General Management Committee to the Council agenda for future meetings to avoid duplication of discussions. At the same time it was noted that this item could still be considered with regard to the specific conservation and management focus of the respective Management Committees.

In 2006, following up on the successful NAMMCO Conference on User Knowledge and Scientific Knowledge in Management Decision-Making in 2003 and the subsequent publication of the proceedings, the Working Group on User Knowledge in Management had been re-established under the chairmanship of Egil Ole Øen (Norway) and new Terms of Reference agreed (see Annual Report NAMMCO 2005, p. 25). However, due to other priorities and staff changes in the Secretariat during this period, the Working Group had not had an opportunity to meet since then.

Greenland highlighted the importance of this issue and the need to maintain a clear focus within NAMMCO on the role of users in marine mammal research, conservation and management. The Conference and its proceedings had provided much insight into approaches in different contexts, and it remained therefore a very useful reference for future discussions.

The Council noted that the joint session of the Management Committee on Cetaceans and the Management Committee on Seals and Walruses had recommended that the issue of user knowledge in management decision-making should be returned to the agendas of the Management Committees for future meetings for discussion in relation to conservation and management recommendations.

The Council agreed to this recommendation, and as a result also agreed to dispense with the associated Working Group, noting that any further dedicated treatment of this issue would be decided in relation to deliberations in the respective Management Committees at future meetings.

11. ENVIRONMENTAL QUESTIONS

Report of the expert meeting on potential positive health effects of consuming whale and seal oil The General Secretary Christina Lockyer presented a summary of the report of the 23

Report of the Council

Expert Meeting on Potential Positive Health Effects of Consuming Whale and Seal Oil (NAMMCO/17/13), organised by NAMMCO and held in Copenhagen on 3 October 2007, with sponsorship from NORDEN (the Nordic Council of Ministers), Indigenous Survival International Greenland and NAMMCO. The workshop was chaired by Professor Lars Walløe (Norway) and attended by a total of 17 experts from diverse backgrounds of medicine, government and industry from all NAMMCO member countries. A summary report from the workshop was presented on behalf of NAMMCO by the workshop chair at the International Conference on Seals and Society in Vaasa, Finland in October 2007.

The expert meeting heard reports of trials and beneficial effects of seal oil consumption on intestinal disorders, arthritic joint pain associated with Irritable Bowel Disease, food allergies, psoriatic arthritis, reducing menstrual pain and cardiovascular disease – especially in the area of lowering blood pressure. Seal oil was also noted as an anti-thrombitic – excess of dietary omega-3 fatty acids have been noted naturally to produce hemorrhagic nose bleeding in Inuit people, for reducing cholesterol levels in blood and enhancing effects of omega-3 fatty acid intake from fish. The meeting also heard how changes in diet in the last 30 years away from traditional marine mammal diet to European diet has resulted in an increase in obesity and also certain types of heart disease in Inuit people. At the same time this dietary switch has produced a lowering of contaminant levels in the diet even though these have remained stable in the marine mammals over time.

The main conclusions were that the effective components were omega-3 fatty acids and antioxidants, especially effective in the unrefined state. The meeting recommended further research to investigate the active components of unrefined marine mammal oil, to publish better documentation of research results and more random sampling and double-blind and placebo experiments. Future research should perhaps focus on specific applications such as in the field of cardiovascular disease.

The Council welcomed the report of the Workshop and expressed its appreciation to Professor Walløe of Norway for chairing the event. It was noted that the workshop had been very useful in identifying the range and extent of research findings on the health benefits of consuming whale and seal oil, while also clearly highlighting further research needs.

Norway stressed the importance of continuing research efforts in this field to better document the health advantages of marine mammals in the diet. The Faroe Islands noted that contaminants in the marine ecosystem lead to accumulations in top predators, especially small whales and seals. It is important that NAMMCO highlight this issue in terms of the need to take action to eliminate marine pollution and stop the contamination of an otherwise excellent food resource.

The Council noted that the health risks associated with high levels of pollutants in some species of small whales and seals warrants continued monitoring. But it was also stressed that the documented health benefits of a diet rich in marine fats need to be balanced against these risks. 24

NAMMCO Annual Report 2007 - 2008

The Council concluded that stronger global efforts to reduce pollution in the marine environment were crucial to ensuring that the high quality food provided by marine mammals can continue to contribute to both local and global food security. The perspective of whaling and sealing nations where marine mammals are an important part of the diet needs to be better communicated in order to strengthen global commitments to eliminate pollution in the marine environment.

OSPAR The Chair recalled that at its last meeting the Council had been informed that OSPAR is consulting with relevant fisheries organisations in connection with the preparation of a Quality Status Report (QSR) for the Northeast Atlantic in 2010. The Chair noted that this work is now well underway within OSPAR.

The General Secretary informed the Council of recent correspondence from OSPAR requesting information on the status of Northeast Atlantic bowhead, blue and northern right whales in relation to an intended update of OSPAR’s 2003 “List of threatened and/or declining species and/or habitats”, which is also to be incorporated into the QSR 2010. Norway reported that the IUCN Red List has recent updates on these species, Cetaceans update of the 2008 IUCN Red List of Threatened Species. In this list Svalbard-Barents Sea bowhead whales are listed as Critically Endangered (CR), northern right whale as Endangered (EN), blue whales in the North Atlantic as Vulnerable (VU) and humpback whales as Least Concern (LC).

The Chair referred to previous Council discussions on the importance of maintaining active working relations with OSPAR and providing up-to-date reliable information on the status of marine mammal stocks dealt with through NAMMCO. It was concluded that the NAMMCO Secretariat should follow the OSPAR QSR process more closely and provide all relevant NAMMCO information on marine mammals. It should be stressed in this connection that the QSR should not only focus on stocks and species classified as “threatened and/or in decline”, but also provide a broader overview of marine mammals as resources in the Northeast Atlantic region, as indeed OSPAR intended to do in relation to fish stocks and fisheries.

12. EXTERNAL RELATIONS

The Chair referred to document NAMMCO/17/11, which provided a compilation of information and observer reports from meetings of a number of international organisations with which NAMMCO has established formal relations. These included observer reports from IWC Commission and Scientific Committee meetings, the 5th meeting of the FAO Regional Fisheries Bodies, Arctic Council SAO meetings, and annual meetings of NEAFC and NAFO and NASCO since the last NAMMCO Annual Meeting. In addition, the Secretariat attended the 5th NARFMO meeting, a forum for the Secretariats of the Regional Fisheries Management Bodies in the North Atlantic, and the Norwegian Small Whalers Union.

Noting the establishment in 2006 of working relations between the respective Scientific Committees of NAMMCO and NAFO on issues related to the role of 25

Report of the Council marine mammals in the ecosystem, the Council welcomed plans for the forthcoming Symposium on the Role of Marine Mammals in the Ecosystem in the 21st Century (29 September – 1 October, Dartmouth, Canada). These issues remain among the core considerations of NAMMCO. NAMMCO is a co-sponsor of the Symposium together with ICES and NAFO. The NAMMCO Scientific Committee has been liaising with the co-convenors on the programme for the Conference and NAMMCO will be hosting a reception for the occasion.

For the guidance of the Secretariat in responding to invitations from other organisations, the Council agreed to delegate NAMMCO observers among member countries as follows: Norway would represent NAMMCO at relevant meetings of NEAFC, Iceland at relevant meetings of NAFO, and the Faroe Islands at relevant meetings of NASCO.

NAMMCO had received an invitation to be represented at the COP9 meeting of the Bonn Convention (Convention on Migratory Species), 1 – 5 December in Rome. Norway offered to represent NAMMCO at this meeting.

13. INFORMATION

The General Secretary introduced NAMMCO/17/12. A variety of reports from scientific and other meetings was presented, as well as information about forthcoming meetings. The Chair thanked the Secretariat for the comprehensive information provided and noted the importance of making information on NAMMCO activities and publications widely available, such as through appropriate attendance at relevant meetings and conferences.

Particular reference was made to the International Conference “Seals and society – how to manage resources and interactions in the Baltic Sea and North Atlantic”, which was held in Vaasa, Finland in October 2007. NAMMCO was formally involved in the programme planning and the Chair of the Council had chaired the final panel discussion at the Conference. The Council was informed that a draft report from this meeting had been prepared soon after the conference, and that the final report was expected to be published and posted on the conference website within the next week.

The Council also welcomed the Declaration on “Seals and Society” adopted by the Nordic Fisheries Ministers at their meeting in Växjö, Sweden on 26 June 2008. The declaration, which the Swedish minister who chaired the meeting has subsequently forwarded to the EU Commissioner for the Environment, clearly emphasises the importance of seals as resources. It also recognises the role of NAMMCO in international cooperation on the conservation and management of seal stocks and work within NAMMCO on hunting methods, and encourages NAMMCO to continue these efforts.

14. ELECTION OF OFFICERS

Halvard P. Johansen (Norway) was elected as Chair of the Council for the next two 26

NAMMCO Annual Report 2007 - 2008 years. Ásta Einarsdóttír (Iceland) was elected as Vice-Chair of the Council for the next two years.

15. ANY OTHER BUSINESS

In concluding the meeting and her second two-year term as Chair of the Council, Kate Sanderson thanked all delegations and observers for their excellent cooperation, both during this meeting and since taking up office. She extended her warmest appreciation to the Secretariat staff for their professional work and for their support during her chairmanship, and welcomed Halvard P. Johansen of Norway to the chair of the Council, wishing him every success in moving forward the important work of NAMMCO.

In appreciation of her efforts as Chair, Halvard P. Johansen on behalf of the Council presented the out-going Chair with a parting gift and thanked her for her competent leadership over the past 4 years.

Appendix 3 OPENING STATEMENTS TO THE COUNCIL BY MEMBER DELEGATIONS AND OBSERVER GOVERNMENTS

GREENLAND – WELCOME ADDRESS Minister of Fisheries, Hunting and Agriculture, Mr Finn Karlsen

Madam Chair, Delegates, Observers, Ladies and Gentlemen,

First of all, it is an honour to welcome you to the 17th NAMMCO Annual Meeting in Sisimiut, Greenland.

The North Atlantic Marine Mammal Commission has provided vital management advice since its creation in 1992.

The above mentioned advices are based on advice provided by the Scientific Committee or on our own requests. Examples of the latter are that we, a couple of years ago, requested from Scientific Committee to give advice on how different quotas on humpback will impact the stock size. NAMMCO´S Scientific Committee concluded that a quota of ten will not have any impact on the population.

Based on that background, Greenland requested a humpback quota from the International Whaling Commission and thereby have the IWC Scientific Committee re-emphasize what the NAMMCO Scientific Committee had already established.

However, our request for a humpback quota was turned down by the majority of countries in the International Whaling Commission despite the conclusion by the Scientific Committee that Greenland had fulfilled all the requirements for such a quota.

The situation has of course created the political consideration of whether or not we should discuss if we are to continue our participation in the future of the IWC.

NAMMCO has a special situation in this matter, and in connection with this NAMMCO Annual Meeting and we would like to express clearly that it is our desire to discuss if it is not the time to alter the Agreement on the establishment of NAMMCO and evaluate whether or not NAMMCO can become a body with a jurisdiction on providing large whale quotas. On this behalf, we from Greenland would like to suggest that we establish an ad hoc working group that investigates this issue.

We all know that seals are now the focus of debate in the international arena, with a proposed EU ban on import as a next example. NAMMCO member countries and sealing countries have in that connection, done extensive work to prevent the ban and limit the harm done to our hunters as much as possible.

We all are aware that the campaign against marine mammal hunting is usually based 31

Report of the Council on ignorance of the fact that conservation and humane killing methods are very important for hunters.

Despite the grave state of the situation I believe that we ourselves also make a contribution to improving the image of hunting.

With that background, I am pleased to hear that the NAMMCO Committee on Hunting Methods is planning to hold an expert Working Group on “Best hunting practices” and I look forward to hear more on this issue.

Lately, we ourselves experienced an incident that we certainly are not proud of, namely that narwhals were found in a certain location with only some usable parts removed. This is just one sign that we need to discuss more good hunting practices among ourselves.

During the years NAMMCO has held seminars and workshops on different hunting methods on different marine mammals. These workshops and seminars have resulted in recommendations. It seems that these recommendations are followed up and I am therefore pleased to find out that there will be a workshop on treatment, processing and utilization of marine mammals as kind of a conclusion to previous workshops; and a publishing of all previous recommendations.

With these words I would once again like to welcome you here; and referring to my statements, I am looking forward to making NAMMCO stronger as an organization that has jurisdiction on large whales because we sometimes wish for a more active role for NAMMCO on certain issues.

Thank you and have good meeting.

FAROE ISLANDS – OPENING STATEMENT

Madam Chair, Minister, Delegates, Observers, Ladies and Gentlemen,

It is a pleasure for the Faroe Islands to be attending the 17th Annual Meeting of NAMMCO, and we would like to thank Greenland for hosting this year’s meeting and inviting us to this beautiful town of Sisimiut.

In 2007 the Scientific Committee of NAMMCO, which the Faroe Islands currently chair, coordinated the major cetacean sightings survey in the North Atlantic – T- NASS 2007. T-NASS was very well planned and successfully carried out, with broad participation across the North Atlantic. The Faroe Islands are pleased to have made our contribution to the shipboard part of T-NASS in our area, and we now look forward to the completion of the data analysis that will provide us with updated abundance estimates, not least for the pilot whale stock in our region.

Madam Chair, this year is very unusual one for us in the Faroe Islands. There has so far not been a single catch of pilot whales around our shores in 2008. We have not had 32

NAMMCO Annual Report 2007 - 2008 an entire year without a pilot whale catch since 1927, and we know that this is not due to any depletion of the stock. Climate and ecosystem fluctuations are likely to be the explanation, and we have also seen dramatic changes in the distribution of some important fish stocks across the Northeast Atlantic in recent years. Hopefully increased research in this area will provide us with a better understanding of these factors. Continued biological monitoring is also very important and we look forward to a more detailed presentation of the Scientific Committee’s recommendations for our regular monitoring and sampling of pilot whales in the Faroe Islands.

The Faroe Islands very much welcome planned discussions this week on procedures for deciding on conservation and management measures. We have always believed that cooperation through NAMMCO should apply actively to all marine mammal stocks of interest to member countries, including large whales, and we have always been ready to support specific measures in this regard. It is 16 years since the NAMMCO agreement was signed, and we believe the time has come for this organisation to activate its mandate and responsibility for managing all whales in the North Atlantic, a responsibility that the IWC is quite clearly not capable of fulfilling.

Although the Faroe Islands are not a sealing nation, we follow discussions on sealing management and hunting methods in NAMMCO with great interest. We are very concerned about the trend towards using trade bans against legitimate forms of sealing in the North Atlantic. Such bans undermine the fundamental principles on which our cooperation in NAMMCO is based, the responsible management and sustainable use of living marine resources and the rights of nations to use – and trade in - their natural resources. As the only international management body for cooperation on seal stocks, NAMMCO seal-related work should be seen as setting the international standard, both with respect to scientific assessment and management measures for shared stocks, as well as for transparent review and discussion of hunting methods in different forms of sealing.

The Faroese delegation is looking forward to contributing to what we hope will be a constructive and productive annual meeting this week.

ICELAND – OPENING STATEMENT

Madam Chair, Delegates, Observers, Ladies and Gentlemen,

It is with great pleasure that the Icelandic delegation attends the 17th Annual Meeting of NAMMCO here in Sisimiut.

NAMMCO plays a great importance for Iceland as sustainable utilisation of marine resources is of fundamental significance for the economic survival of the Icelandic people. In fact we have no other alternative then to give sustainable utilisation of marine resources such a high status.

Sustainable utilisation of marine mammals is not only important to Iceland but it is crucial for all of the NAMMCO member states. The main basis for our economic 33

Report of the Council welfare is utilising the living resources of the sea. Marine mammals are not only an important part of the marine ecosystem. They are a part that must be utilised in a sustainable way, like other parts of the ecosystem and there is no logical reason for treating marine mammals differently then other living resources of the sea.

For this reason international cooperation in this field is of a great importance to us all and we need to work together for the sustainable utilisation, conservation and study of these resources. NAMMCO has made valuable contributions to the conservation and sustainable management of marine mammals.

In particular the work conducted by the Scientific Committee has been of great importance to Iceland. As an example, assessments by the Scientific Committee have formed the main basis for management decisions taken by Icelandic authorities concerning fin and minke whales.

In 2007, Iceland participated in the largest cetacean survey ever conducted in the world (T-NASS). This survey was successfully coordinated by the Scientific Committee of NAMMCO.

Iceland adheres strongly to the ecosystem approach to management of marine resources, including marine mammals. This view is shared by the other NAMMCO countries. To advance this approach a comprehensive scientific programme is being conducted on the feeding ecology of common minke whales in Icelandic waters. Iceland was happy to present the preliminary results from this programme at the NAMMCO council meeting in Selfoss in 2006. Preliminary findings from this programme indicate that commercial fish species such as cod constitute a considerably higher portion of the minke whale’s diet than previously assumed. These results underline the importance of scientific work for a better understanding of the marine ecosystem for management.

We are confident that, as past meetings, this meeting will be fruitful and constructive, based on objective, and science-based approach.

NORWAY - OPENING STATEMENT

Madam Chair, Minister, Delegates, Observers and Guests, Dear Friends,

It is indeed a pleasure to meet here in Sisimiut, Greenland, for the seventeenth meeting of the NAMMCO Council. I believe that we, during this meeting, will confirm the status of NAMMCO as a useful regional management body for marine mammals.

Many countries accept whaling and sealing in some nations, both in countries with a developed economy and in countries where the economy is less developed depending on who is conducting the whaling and sealing. Norway has the strong opinion that all whaling and sealing have to be based on science, and that no whaling and sealing should be conducted if it is not sustainable.

34

NAMMCO Annual Report 2007 - 2008

The debate about management of marine mammals today is mainly emotional. It is disturbing that the attitude towards science as the basis for managing whale stocks is vanishing. This is especially important as we have to base our management of wildlife in general on science. Also, we have to solve international conflicts in the environmental field (global warming, biological diversity, IUU fishing, effects of pollution, etc.) on a scientific basis. Whaling and sealing is not a major issue in this context, but the actions of governments in this matter may create an international precedent for similar actions in more important issues. We cannot accept that a legal activity conducted with the best practice in one country is not accepted in another country because of emotions.

We recognize the fact that governments allow themselves to describe some mammals as pest animals (musk rat, possum, kangaroo, horse, camel) and consequently accept that they may be killed without any control of the methods used or supervision of the culling. This is not consistent with what these countries demand from whaling and sealing nations.

During the past two years we have seen an ongoing campaign in many European countries against trade in seal products. Some countries have introduced legislation to this effect already, and others will follow suit. In July the Commission of the European Communities proposed regulation of the European Parliament and the Council concerning trade in seal product. This underlines that it is mandatory that we who live in the Arctic and depend on sustainable use of the living marine resources available to us, including the marine mammals, stick together and defend our right to sustainable harvest of the surplus of nature’s production and make a living of selling the products.

Our understanding of the proposed regulation in the EU of trade in seal products is that the European market will be open for seal products coming from Inuit hunt and from countries that have a respectable regulation of the seal hunt. It is therefore mandatory that the sealing nations in the North Atlantic strive to develop and implement the best possible hunting methods and acceptable control measures. In that way we can set the standards also for other legal hunting activities, also in countries that do not harvest marine mammals. I think we can be proud of our contribution to the amelioration of the animal welfare in hunting activities.

In this respect the work of the NAMMCO Committee on Hunting Methods is important. This Committee is setting the standards for the hunt of marine mammals, and these standards represent best practice. We will now ask this Committee to codify what is best practice in different kinds of sealing.

The NAMMCO Inspection and Observer Regime is the only control regime in force that covers marine mammals. We think it is important that we now give priority to update this regime and take into account experience gained and the new techniques that are developed.

Greenland has this year experienced that they did not get a quota of humpback whales 35

Report of the Council despite a scientific advice stating that the requested quota would be sustainable. Such an experience emphasises how important it is that the NAMMCO Scientific Committee starts to study general models for conservation and management of baleen whales.

Finally, I would like to reiterate that Norway continuously strive to develop a coherent and active conservation and management regime for marine mammals based on modern principles for the management of species, habitats and ecosystems.

I wish you all a fruitful meeting.

JAPAN – OPENING STATEMENT

The delegation of Japan expresses its appreciation for the hospitality and warm welcome we have received from the Government of Greenland. We are pleased to be attending the Seventeenth Meeting of the NAMMCO Council.

Indeed, we believe it appropriate that this meeting of the Council is being held in Greenland following the decision at the 60th Annual Meeting of the IWC that rejected the legitimate and scientifically supported request for humpback whales made by Denmark on behalf of Greenland. The continuing rejection of Japan’s request for a quota for its small-type coastal whaling communities by the IWC puts Japan and Greenland and our cultures in the same position as victims of an organization whose agenda and functioning has been overtaken by anti-whaling zealots. The people and the Government of Greenland have our heartfelt understanding and sympathy. Clearly, this emphasizes the need for strengthened regional management and/or a new global arrangement.

As we noted at your sixteenth meeting, Japan has little confidence that the current situation in IWC will improve; however, we are committed to work within the “Future of IWC” process initiated by Chairman Hogarth at least until June of next year. We believe that the understanding shared between Japan and NAMMCO member countries that the management of all marine living resources should be based on science, conformity with international law and respect for cultural diversity must constitute the basis of our participation in that process and must continue to be communicated to all members of the IWC. At the same time, we appreciate the participation of individuals from NAMMCO member countries in the working group that is developing a “safety net” which could assume the role of managing sustainable whaling in the absence of IWC functioning.

Cooperation between Japan and NAMMCO member countries is also important in other international fora where whaling and other marine and fisheries issues such as marine protected areas, improvement of regional fisheries management organizations and the management of fisheries in waters beyond national jurisdiction are currently being discussed. One such forum will be the IUCN World Conservation Congress which will be held in Barcelona from October 5 to 14. Whaling and many other fisheries issues are on the agenda for this Congress and we look forward to working 36

NAMMCO Annual Report 2007 - 2008 with you to try to ensure that decisions made are consistent with our shared understanding concerning the basis for managing marine living resources.

Finally, we would like once again to note that research on interactions between whales and fisheries and ecosystem modeling is a subject of shared interest between Japan and the members of NAMMCO. We remain convinced that collectively, our work on these issues will provide a strengthened scientific basis for improved management of all marine resources.

Thank you.

Report of the Council

Appendix 4 PRESENTATION TO THE 17TH ANNUAL MEETING OF NAMMCO BY PETER OLSEN, CHAIRMAN OF KNAPK – THE ORGANIZATION OF FISHERMEN AND HUNTERS IN GREENLAND

KNAPK expresses great pleasure in having the opportunity to address NAMMCO on the subject of “Sealing and Whaling in Greenland”. KNAPK has the following to say.

Concerning large whales KNAPK strongly demand that the processing of quotas on larger whales such as minke, fin, humpback and Greenland right whales, come under the auspices of NAMMCO. The reason for this demand arose from the recent IWC meeting in Chile during the month of June 2008, when Greenland was denied a catch of humpback whales, despite there being absolutely nothing to hinder this administratively and scientifically. Greenland was thus unjustly denied their catch.

Greenlandic hunters and fishermen cannot accept that the IWC can deny quotas for these whales. The KNAPK arranged a hearing and the general opinion was that Greenland should leave the IWC in favour of moving to NAMMCO with respect to questions of allocation of quotas for larger whales.

The decision to deny a catch of humpback whales by the IWC and especially the EU members was made clearly on the basis of emotions. This can hardly be justified.

KNAPK is of the opinion that a sustainable harvest of any living resources is a human right for the Inuit in the Arctic, and an unjustifiable denial is cultural discrimination against our way of life and is oppressive behaviour. This is a violation of human rights and KNAPK is ready for this case to be brought to the Human Rights Commission.

In recent years the members of KNAPK have observed that the numbers of humpback whales are drastically increasing, which has had a negative effect in that fishermen are experiencing problems with pound nets.

We urge the member nations of NAMMCO to discuss our suggestion that NAMMCO becomes authorized to allocate quotas for whales, and it is our hope that you will take this suggestion into consideration.

KNAPK also kindly urges the Minister for Fisheries, Hunting and Agriculture, Mr Finn Karlsen, to work to establish allocation of quotas by NAMMCO through the Danish membership of the IWC. In this regard, we refer to Minister Finn Karlsen’s letter to the Danish Minister for Foreign Affairs, Mr Per Stig Møller, concerning establishing a working group.

KNAPK also urges member nations within NAMMCO to consider the topic of trade of whale products because this is an important topic and should be an item for discussion.

NAMMCO Annual Report 2007 - 2008

Concerning seals KNAPK also conducted a hearing among its members concerning seals, and we will present you with the results of that hearing.

Ringed seals The seal population in Central West Greenland between Sisimiut and Aasiaat is showing signs of change: their numbers are decreasing. The reason is climate change with changes in the pattern of the west ice. The population between Nuuk and Paamiut however, is reportedly showing signs of increasing in numbers, while the seal population in the Thule region does not seem to have undergone any changes.

Harp seals The number of harp seals is reportedly constantly on the rise in Western Greenland, especially in the Thule region, and it is evident that harp seals are breeding off the waters of Sisimiut.

Young harp seals Their numbers show evidence of increasing throughout Western Greenland and also that they have begun to breed in both Southern and Western Greenland. Young harp seals are staying in our waters until the month of December, where small and thin seals have been sighted.

All member organizations claim that there is an increasing number of seals in Greenlandic waters, especially harp seals. Breeding in Greenland waters is increasing.

The Greenlandic coast is vast and the dark time during winter often makes it difficult to conduct hunting. Catching seals with nets is conducted and is vital to hunters and their families. The seal is important in those areas where there are dogs, especially during the dark period. KNAPK would like to stress to NAMMCO that catching seals with nets is something the hunters cannot manage without. We therefore urge that this practice be allowed to continue unhindered.

In conclusion, KNAPK, on behalf of its members, wish NAMMCO fruitful discussions during this year’s Annual Meeting.

Appendix 6 PRESS RELEASE 4 September 2008

Regional management of whales and seals in the North Atlantic is the way forward

Whaling and sealing nations in the North Atlantic, meeting in Sisimiut, Greenland this week, confirmed their commitment to ensuring the sustainable utilisation of marine mammals through science-based management decisions, stressing the vital importance whales and seals have as renewable resources for economies and cultures across the region.

Greenland, Iceland, the Faroe Islands and Norway are members of NAMMCO – the North Atlantic Marine Mammal Commission, an international body for cooperation on the conservation, management and study of whales, seals and walruses in the North Atlantic, which held its 17th annual meeting this week in Greenland. The Commission was established in 1992 through an agreement which provides the organisation with the international competence to make recommendations to member countries on conservation and management measures for all stocks and species of whales and seals in the region.

In the light of interest expressed by Greenland in resuming a catch of humpback whales in its waters, the Cetacean Management Committee of NAMMCO recommended that the total quota of humpbacks in West Greenland in 2009, including by-catches, should not exceed 10 animals. This recommendation was based on the 2006 advice from the NAMMCO Scientific Committee that such a level of catch is well within sustainable limits, and noting that the most recent abundance estimate for West Greenland humpbacks from 2007 is higher than the previous estimate from 2005.

New abundance estimates for a number of other key whale stocks in the North Atlantic, including fin whales, minke whales and pilot whales are also expected to be completed in the very near future. These will be based on data from the comprehensive Trans North Atlantic Cetacean Sightings Survey carried out in July 2007 and coordinated by the NAMMCO Scientific Committee. T-NASS was the largest contiguous cetacean sighting survey of its kind ever conducted, spanning the North Atlantic with participation by Canada, Greenland, Iceland, Faroe Islands, Norway and Russia, and in partnership with surveys carried out at the same time in the USA and in European waters. Regular monitoring of trends in the size of whale populations and their distribution through sightings surveys are an essential tool in the management of whale stocks.

The results of the T-NASS survey, as well as the Icelandic minke whale research programme, fisheries surveys and other studies point to significant changes in North Atlantic marine ecosystems in recent years. NAMMCO has therefore requested its Scientific Committee to examine the latest information on these changes and the 41

Report of the Council nature of predator-prey relations, and their implications for the management of all marine resources.

Sealing was also a major focus of this year’s NAMMCO meeting. The Commission has requested a special meeting of experts to assess best practices in different forms of seal hunting. The NAMMCO Committee on Hunting Methods brings veterinary experts and hunters together on a regular basis to review and exchange experiences on methods and equipment used in whaling, sealing and walrus hunting and to make recommendations for improvements.

Although NAMMCO does not deal formally with trade issues, moves within the European Union towards imposing import bans on seal products prompted all member countries at the NAMMCO meeting this week to express their serious concerns about the implications such trade barriers can have for the responsible management and sustainable use of abundant seals stocks across the North Atlantic, and the economies of the many communities dependent on these resources.

The health benefits of consuming whale and seal oil were the subject of a specialist workshop organised by NAMMCO and its report on the most recent research findings and further research requirements was presented to the meeting. The health risks associated with high levels of pollutants in some species of small whales and seals warrants continued monitoring. But the documented health benefits of a diet rich in marine fats need to be balanced against these risks. NAMMCO members stressed that stronger global efforts to reduce pollution in the marine environment were crucial to ensuring that the high quality food provided by marine mammals can continue to contribute to both local and global food security.

In summing up the meeting and concluding her term as Chair of the NAMMCO Council, Kate Sanderson from the Ministry of Fisheries and Natural Resources in the Faroe Islands, said: “For our nations in the North Atlantic, with a fundamental stake in conserving our marine resources and utilising them sustainably, it is clear that NAMMCO’s regional approach to cooperation on the management of whaling and sealing is a constructive and effective way to work, as is our regional approach to fisheries cooperation in the region. Hopefully this can also serve as a model for other regions around the world. “

Halvard P. Johansen of the Ministry of Fisheries and Coastal Affairs in Norway was elected as the new chair of the NAMMCO Council.

1.2 REPORTS OF THE COMMITTEE ON HUNTING METHODS

The Committee on Hunting Methods held a telephone meeting on 13 December 2007 from 14:00 to 15:00. Online were Egil Ole Øen, Chair and Hild Ynnesdal (Norway), Jústines Olsen, (Faroe Islands), Ole Heinrich (Greenland), Kristjan Loftsson (Iceland), and Christina Lockyer and Charlotte Winsnes from the Secretariat.

1. OPENING PROCEDURE

The Chair of the Committee, Egil Ole Øen, welcomed the Committee members to the meeting. The draft agenda was adopted with the addition of three items under Any Other Business. Charlotte Winsnes was acting as rapporteur.

2. NEXT MEETING

The next meeting will be held in Copenhagen back to back with the Sub-Committee on Inspection and Observation on 13 and 14 February 2007. The meeting will be held at the Nordatlantensbrygge. Committee members were reminded to submit any updates on references and laws and regulations in member countries to the Secretariat.

3. WORKSHOP ON "HANDLING, PROCESSING AND UTILISATION OF HUNTED MARINE MAMMALS"

In March 2007, the Council approved the Committee's idea to organise a workshop (WS) with the working title “Handling, processing and utilisation of hunted marine mammals” with the following terms of reference: • To maximise the quality and quantity of products obtained from hunting through exchange of information regarding handling, processing and utilisation. • To make recommendations which are relevant to the workshop topic.

The Committee discussed the suggested timing of the WS (first half of September 2008) and agreed that it would be difficult to keep this date considering other meetings planned for the same period (NAMMCO 17 and Norwegian/Russian Sealing meeting in late August). It was agreed to postpone the WS until the fall of 2009. The meeting venue will be decided upon at a later stage.

The following points were raised and briefly discussed under this agenda: • Steering Committee: The Committee on Hunting Methods will plan and organise the WS in consultation with possible resource persons. • Meeting venue: in a member country or Copenhagen? • Content and programme: Should the WS include all marine mammals or just seals and whales? Food security authorities are important players and must be part of the WS. Should the WS include both theoretical and practical aspects? A very brief introduction to hunting methods with respect to how they are done in different places as these have bearing on the meat quality, etc. For each hunt, analyze and identify possible problems as seen from the various perspectives of 43

Report of the Committee on Hunting Methods

the hunters and the food authorities with the aim of solving them to maximise the market situation. Hunting of marine mammals results in production of food and related items and the revenue must be maximised and secured. • Participants: Hunters, experts, managers, market representatives, food security authorities from NAMMCO member countries, Japan, Canada, Chukotka, Alaska. • Finances: Must seek financial sponsorship outside of NAMMCO. Will approach NCM, ISI Greenland, NORA and similar.

4. ANY OTHER BUSINESS

4.1 New Hunting Knife in the Faroe Islands At its last meeting in January 2007 the Committee expressed its interest in receiving a report describing and evaluating the knife and the method of use as this would be beneficial to NAMMCO. It was recommended that such work be undertaken by the Faroe Islands.

Olsen reported that a document describing the results of the use of the new hunting knife for the killing of Pilot whales would be presented to the Committee for its evaluation in advance of its next meeting in February 2008.

4.2 Hunting methods for Bowhead whales At the last IWC meeting in 2007, Greenland was allocated a quota of 2 Bowhead whales in 2009 and would like to discuss conceivable methods for hunting of Bowhead whales in Greenland at the next meeting in the Hunting Committee. Greenland will supply a background document to be distributed in advance of the meeting.

4.3 World Society for the Protection of Animals (WSPA) WSPA had approached NAMMCO with a request for various types of information and access to meeting documents related to the work of the HM Committee. The Secretariat had drafted a response that was presented to the Committee for its comments.

5. APPROVAL OF THE REPORT

The report was approved by correspondence on 11 January 2008.

------REPORT OF THE COMMITTEE ON HUNTING METHODS

The Committee on Hunting Methods met on 13 February 2008 from 9:30 to 17:30 in the Faroe Islands Representation in Copenhagen. Present were Egil Ole Øen, Chair and Hild Ynnesdal (Norway), Jústines Olsen, (Faroe Islands), Ole Heinrich and Amalie Jessen (Greenland) (Jessen attended agenda items 5 to 7), Kristjan Loftsson (Iceland), and Christina Lockyer, Mario Aquarone and Charlotte Winsnes from the Secretariat. 44

1. INTRODUCTORY REMARKS, ADOPTION OF AGENDA AND APPOINTMENT OF RAPPORTEUR

The Chair of the Committee, Egil Ole Øen, welcomed the Committee members to the meeting. The agenda was adopted with the addition of item 7.1 "A request from the Heads of Delegation meeting regarding a possible follow-up on best practises in sealing. Charlotte Winsnes acted as rapporteur.

2. UPDATES ON HUNTING METHODS IN MEMBER COUNTRIES

The lists of references on hunting methods (NAMMCO/HM-February 2008-2), and laws and regulations in member countries (NAMMCO/HM-February 2008-3) were updated (see Appendices 1 and 2 of this report).

Faroe Islands Olsen (Faroe Islands) reported that there had been one addition to the regulations for pilot whale hunting in the Faroe Islands, Executive Order No. 87 of 20 September 2007 on protections of whales. The idea is to prevent whales which have or will be tagged with sattelite transmitters to be harvested.

Greenland Heinrich (Greenland) reported that there have been reduced sightings of minke whales in East Greenland. As a consequence the hunters have requested the Home Rule Government to give permission to catch fin whales as they are sighted frequently. This request has so far been denied due to lack of adequate hunting equipment.

Iceland Loftsson (Iceland) had no new information to report under this item. Norway Ynnesdal (Norway) noted that in Norway quota regulations on seal and whale hunting are revised every year, and that the regulations for 2008 are still under preparation.

The “Blue Box” system - the new electronic monitoring system for electronic surveillance of the Norwegian minke whaling (for description see the 2005 Committee report) seems to be well functioning. An evaluation of the system will be undertaken after the 2008 season at which time the system has been operative for three seasons.

3. WORKSHOP ON "HANDLING, PROCESSING AND UTILISATION OF HUNTED MARINE MAMMALS"

Prior to the meeting the Chair had asked Jústines Olsen to prepare some points for discussion (appendix 3). Also the report from the last meeting was presented as background documentation.

The Committee agreed on the following:

45

Report of the Committee on Hunting Methods

 The Workshop will be held in Sandefjord, Norway at Hotel Atlantic in week 45 (2 – 6 November) or 46 (9 – 13 November) in 2009. This was also the venue for the 2nd workshop on ballistics. Sandefjord is fairly easy to reach (Torp airport and Gardemoen + train). Various artefacts that might be useful to exhibit may be found at the Whaling museum and also at the hotel itself which has a renowned display of hunting objects.  The WS will be a three day event with focus on whales and seals and a mixture of lectures and discussions. Day 1: - General introduction – common aspects for all types of hunt, how are hunting conducted – generally what kind of impact the various hunts have on meat and skin quality - cultural differences in treatments. Important to emphasis that this overview of hunting methods should only take note of the impact a certain method has on the product. - how and where to slaughter the animal from a hygienically point of view Day 2: Species specific sessions running parallel or in sequence: - Whales; large and small - Seals; young or grown up Day 3: Conclusions and Recommendations  Olsen's programme input to be a possible introduction lecture at the WS  Heinrich mentioned that Greenland could nominate a person who could talk about product development.  If possible it would be very good to have visual documentation on topics such as treatment of meat from seals and whales. Some raised the issue that power point presentations often took priority to filming because of the time control aspect.  The Steering Committee for the WS will be the Hunting Committee. In addition Glenn Williams from Nunavut Tunngavik Inc. will be asked to participate in the planning and implementation of the WS, as he did in the last two workshops.  The WS will be open as in previous workshops. Special invitations will be sent to Chukotka and Alaska, and in general all participants from earlier meetings will be notified. The Secretariat will prepare a list of possible participants that will be circulated to the Committee for comments.  The WS has been allocated NOK 100 000 from NAMMCO but will need to seek external funding.  The next meeting in the Steering Committee will be a telephone meeting in April, and it is envisaged that a second telephone meeting will be held before the summer holidays.  The Chair in cooperation with the Secretariat will prepare a more detailed programme for discussion prior to the next telephone meeting.

4. NEW HUNTING EQUIPMENT IN THE FAROES ISLANDS

At its January 2007 the Committee expressed its interest in receiving a report describing and evaluating the new "knife" and the method used in the Faroes Islands. 46

NAMMCO Annual Report 2007 - 2008

Document HM-February/2008-4 " Development and testing of new whale killing equipment in Faroese whaling" had been prepared by Olsen for consideration by the Committee.

The Committee congratulated and commended Olsen for his successful work on developing this new tool. They recommended that more work be done with respect to documentation on method and use before a possible publication. It was noted that although the new killing equipment had been developed from the traditional knife it is no longer a knife but a spinal lance. It was generally thought that the spinal lance represents an improvement with respect to killing time and suffering.

5. BOWHEAD WHALES FUTURE

At the last IWC meeting in 2007, Greenland was allocated a quota of 2 bowhead whales. The bowhead was put under total protection in 1938 thus Greenland has no up to date experience on hunting of this species. To ensure the best possible hunt Greenland has sent a request for advice to Alaska where they do hunt the bowheads, and in addition asked for NAMMCO's input through the Committee on Hunting Methods on conceivable methods for the hunting of bowhead whales.

Jessen distributed a draft project outline for consideration and information. The project outline is intended for the next IWC and gives a thorough description of background, biology, legal frame in the past, today and in the future (laws and regulations), hunting methods, utilisation, health aspects and also references to the bowhead recovery program in Nunavut and Alaska.

Greenland's intention is to use a harpoon canon with a fin whale grenade. The Committee pointed out that there are two main target areas on the bowhead whale: neck and thorax?, and that one should always shoot on the side and never from behind the animal. It was recommended to initiate i. e. a 3-year trial period in which the hunting methods could be developed. Furthermore it was agreed that it would be important to identify a small number of vessels (2 – 3) with a license to hunt the quota under monitored and controlled circumstances and thus gain the necessary experience to adapt the best possible hunting methods.

The Committee agreed to review the draft plan for hunt when this was ready.

6. NEXT MEETING

The next ordinary meeting will be held in Copenhagen in January/February 2009.

7. ANY OTHER BUSINESS

7.1 Evaluation of best practices in sealing The Heads of Delegation had forwarded a request to the Committee to identify main issues for a possible Workshop on best practices in sealing. The work should build upon the knowledge and experiences already gathered in previous workshops 47

Report of the Committee on Hunting Methods organized by the Committee and possible new developments emerging since the last workshop held in 2006.

The Committee was also asked to consider whether this should be an open forum or an expert meeting with attendance by invitation only. Tentatively NOK 50 000 were set aside for this work.

The Committee agreed to suggest focusing the work on best applicable methods, i.e. to critically assess the various hunting methods within their context. Given the legal framework is the preferred hunting method and equipment the best possible practice in a particular setting? Consideration should also be given to control and monitoring aspects as well as training of the hunters. The work should end up with recommendations on best practices based on state of the art in sealing today.

The Committee further recommends that the work be undertaken by a smaller more focused working group rather than through a workshop. Participation would be by invitation only and would encompass hunters and experts from all NAMMCO member counties. In addition invitations should be sent to sealing nations like Sweden, Finland and Canada.

The first step would be for the NAMMCO Secretariat to collect all relevant information from the previous workshops and draft a summary report to be used as a working document. Manuals and reports from other sealing counties will also be included.

Tentatively a first meeting of the Working Group was scheduled in connection with NAMMCO 17 in September 2008.

1.3 REPORT OF THE COMMITTEE ON INSPECTION AND OBSERVATION

The Committee on Inspection and Observation met in the Office of the Faroe Islands representation in Copenhagen, 14 February 2008 from 09:00 – 13:00. Present were Ole Heinrich, Chair (Greenland), Egil Ole Øen and Hild Ynnesdal (Norway), Jústines Olsen (Faroe Islands), Kristjan Loftsson (Iceland), Christina Lockyer, Mario Acquarone and Charlotte Winsnes from the Secretariat.

1. OPENING PROCEDURE

The Chair of the Committee, Ole Heinrich, welcomed the Committee members to the meeting. The draft agenda was adopted and Charlotte Winsnes was appointed as rapporteur.

2. TERMS OF REFERENCE FOR THE COMMITTEE

At its last meeting the Council decided that the existing Sub-Committee should now report directly to Council rather than the Management Committee; it would therefore no longer be a Sub-Committee but rather a self-standing one. Document NAMMCO/I&O-February/2008-2 containing the revised terms of reference for the former Sub-Committee was presented to the Committee. In addition to the editorial changes with respect to the reporting body the text of paragraph 3 had also been revised by deleting the word annually to accommodate those years when the convening of the committee is not required or called for. The Committee took note of the revisions.

3. REPORT FROM THE 2007 SEASON

Document NAMMCO/I&O-February/2008-3 contained the report from the Secretariat of the Observation Season 2007. The document was presented as an information item and the Committee was not asked to revise or approve the report.

4. REVISION OF THE TEXT OF THE PROVISIONS OF THE INSPECTION AND OBSERVATION SCHEME

The Observation Scheme has been operative since 1998. Before 2002 only land based observations were carried out. However the tendency during the recent years has been to have observers out at sea. Being out at sea requires other kinds of safety measures than when operating on shore. Furthermore Norway has developed and implemented a new automatic monitoring system for its whale hunt operations. The Provisions do not take sufficient account of this new situation, and Council had at its last meeting recommended that amendments to the provisions be made to:

- integrate requirements for observer training to ensure observer safety onboard vessels, and 59

Report of the Committee on Inspection and Observation

- take account of recent technological developments in automated monitoring in the Norwegian whale hunt.

The Committee was presented with a revised text of the Provisions that had incorporated the editorial changes with respect to the reporting body (see agenda item 3 above). The Secretariat also presented an overview of some of the safety requirements for out at sea operations in member countries.

It was generally agreed that it was important to differentiate between the observer and the ship crew. The observer is more akin to passengers on a boat and hence he/she must have information/knowledge on how to take care of themselves in an emergency situation i.e. where the survival suits are, how to get dressed, how they work, where to evacuate, emergency exits, life boats, etc.

During the discussions under this agenda item it was clear that the Committee needed more time to suggest amendments with respect to safety requirements and also the automated monitoring system. It was generally acknowledged that this represented a good opportunity to revisit the text of the Provisions with respect to necessary adjustments it being more that a decade since it was first adopted. The Provisions Section A, B, C and Appendix 1 were adopted in 1996 and Appendix 2, Guidelines to Section B was adopted in 1997 with a minor amendment in 1999. As a starting point Appendix 1 and section C will be revised by correspondence before the next Council meeting. In addition new issues had surfaced (see agenda item 5.1 below) and it was recommended to revisit the standard reporting forms that the observers use in order to see if there were possibilities for improvements.

4. EXPERIENCES WITH USING AUTOMATED MONITORING OF WHALE HUNTING IN NORWAY

The Committee had been asked to provide a report to the next Council meeting on experiences in using automated monitoring in whale hunting in Norway. However the Committee choose to postpone one year in anticipation of the announced evaluation of the system that Norway will carry out after the 2008 season.

5. ANY OTHER BUSINESS

5.1 Training of observers In connection with discussion under agenda item 4. above the Committee recommended that the Secretariat establish a more formalised system of guidance and preparation of observer candidates prior to their assignment. The system is functioning today but it was thought that a more formalised frame would be beneficial for all concerned. Based on the guidelines to Section B of the Observer Scheme the Secretariat should formalise the training both with respect to the general information supplied by the Secretariat and the activity-specific preparation that are carried out by the national authorities with regards to interpretation of laws and regulations and duties of national inspectors.

2.1 REPORT OF THE MEETING OF THE MANAGEMENT COMMITTEE FOR CETACEANS 3-4 September 2008, Sisimiut, Greenland

1. CHAIRMAN’S OPENING REMARKS

The Chair of the Management Committee, Halvard P. Johansen, welcomed delegations and observers to the meeting. Participants to the meeting are listed in Section 3.2 of the Annual Report. Documents available to the meeting are listed in Appendix 2.

The Chair opened the meeting with a statement of the role and duty of the Management Committees from the Agreement. He noted that NAMMCO had given specific management advice in the past, most recently to Iceland regarding the minke whales and fin whales.

2. ADOPTION OF AGENDA

The agenda, as contained in Appendix 1, was adopted.

3. APPOINTMENT OF RAPPORTEUR

The Secretariat was appointed as rapporteur for the meeting.

4. CONSERVATION AND MANAGEMENT MEASURES FOR WHALE STOCKS

The Chair summarised past proposals for conservation and management and responses with reference to document NAMMCO/17/MC 3 (Annex 1), and summarised past requests to the SC and responses with reference to document NAMMCO/17/MC 4 (Annex 2). All new recommendations to member countries on scientific research arising and approved by the Management Committee are contained in Appendix 5.

4.1 and 4.2 Beluga and Narwhal Status of past proposals In 2006, the Management Committee for Cetaceans, while commending Greenland for the recent introduction of quotas and reduction in the harvest, expressed serious concern that takes of beluga and narwhal in West Greenland, according to the advice of both the NAMMCO Scientific Committee and the Canada/Greenland Joint Commission on Conservation and Management of Narwhal and Beluga (JCNB) Scientific Working Group, were not sustainable and would lead to further depletion of the stocks. The Management Committee therefore strongly urged Greenland to take action to bring the removals of belugas and narwhals in West Greenland to sustainable levels.

Advice from the Scientific Committee 65

Report of the Management Committee for Cetaceans

The Scientific Committee has been requested to provide an assessment in all areas of narwhal and beluga in West Greenland, and narwhal in East Greenland, as well as to provide advice on the effects of human disturbance, including noise and shipping activities, on the distribution, behaviour and conservation status of belugas, particularly in West Greenland.

With regard to surveys, it has also been recommended that future surveys for beluga and narwhal be planned using the international expertise available through the Scientific Committee of NAMMCO. In addition, if and when new survey methods are applied, they should be calibrated against previously used methods so that the validity of the survey series for determining trends in abundance is ensured.

The last assessment was carried out in 2005 and uncertainties with abundance estimates and stock structure remained. The Greenland Institute of Natural Resources (GINR) has since implemented a monitoring plan from 2007-2011, covering both wintering and summering aggregations, including stock identification of all major aggregations. New surveys were undertaken in 2006 and 2007 in West Greenland, including Melville Bay and Inglefield Bredning. More tags were deployed on narwhal in West and North Greenland in 2007. An aerial survey for narwhal was conducted in East Greenland in the summer of 2008.

The Scientific Committee now recommends an update of the assessment of both narwhal and beluga as new data warrant such an exercise. The NAMMCO /JCNB Joint Working Group should meet before March 2009, to allow the updated assessment to be available for setting the new quota series. Greenland should submit fully corrected estimates derived from the 2006, 2007 and 2008 surveys to the NAMMCO /JCNB Joint Working Group. Furthermore the Scientific Committee recommends, as in 2006, that advice be forwarded to the JCNB to be dealt with at their next meeting.

The Scientific Committee reported that plans for the 2007 narwhal and beluga surveys were not presented to the T-NASS Committee and had therefore not been reviewed by this Committee. No reports have been forwarded to the Scientific Committee, and it is unknown which methods have been applied.

The Management Committee noted that, as in 2005 and 2006, the Greenland quotas for narwhal and beluga remain much above the quota recommended by the Scientific Committee of 135 narwhals and 100 belugas for West Greenland. However, the Committee also recognizes that new preliminary data on abundance show higher estimates than previously.

Greenland noted that the 2007/08 quota for narwhal includes the quota for Melville Bay of 100 narwhals, for which there is no scientific recommendation on catch levels. Greenland would encourage their scientists to continue to submit their results on distribution studies. In commenting on the given quotas, Greenland reported that there had been a hunting seminar in the spring when scientists informed hunters that numbers had increased since setting quotas. Greenland underlined that the knowledge 66

NAMMCO Annual Report 2007 - 2008 and expertise of both biologists s and hunters must be respected and taken into account.

Greenland also informed the Committee of an incident in August this year regarding a reported take of 48 narwhals in Rømer Fjord, Illoqqottormiit, from which only the blubber and tusks of the animals had been taken. However, an observer from the Greenland Institute of Natural Resources later delivered a field report counting 32 narwhals. Greenland reported that the matter was under police investigation.

In relation to the publication of the Greenland Red List 2007, in which the status of narwhals has been erroneously described as “in danger of imminent extinction” if hunting continues, Greenland also reported that scientists at the GINR had been urged to ensure the accuracy of information provided as a basis for such publications.

Requests for advice The Committee agreed to recommend that the Scientific Committee update the assessment of both narwhal and beluga, noting that new data warrant such an exercise. The NAMMCO /JCNB Joint Working Group should meet before March 2009, to allow the updated assessment to be available for setting the new quota series. Greenland should submit fully corrected estimates derived from the 2006, 2007 and 2008 surveys to the joint Working Group. In addition, as in 2006, advice should also be forwarded to the JCNB.

4.3 Fin whales Advice from the Scientific Committee In 2007 the Scientific Committee was requested to complete an assessment for the Northeast Atlantic stocks as a next step in the process of assessing fin whale stocks in the areas of interest to NAMMCO countries.

There have been five assessments since 1999, the last in 2006, and work is outstanding with regard to abundance estimates and stock structure. More recent genetic studies still support a lack of genetic divergence across the North Atlantic. The final genetic results for the Faroese biopsies, which are crucial since preliminary results pointed to a different stock, are still not available.

New abundance estimates deriving from T-NASS include: 1. Iceland-Faroe Islands: the new estimate was presented to the NAMMCO SC WG on Abundance Estimate; the subsequent revised analysis was later endorsed by the International Whaling Commission (IWC) SC; 2. Norway: an estimate from the cycle 2002-2007 will be available in 2009; 3. Greenland: the new estimate from T-NASS has still to be finally accepted; 4. Results from Canada, SNESSA and CODA should become available soon; 5. Some changes occurred in distribution, but are to be investigated further.

Requests for advice The Management Committee reiterated its recommendation to request the Scientific

Committee to complete an assessment of fin whales in the North Atlantic and also to include an estimation of sustainable catch levels in the Central North Atlantic. This work should be initiated as soon as all estimates become available and before the next meeting of the Scientific Committee.

4.4 Minke whales Advice from the Scientific Committee An assessment of the Central minke whale stock had been carried out in 1998 and 2003, with some uncertainties regarding stock delineation remaining. Newer genetic studies indicate little variability in the Northeast Atlantic and North Atlantic. The Icelandic Research Programme has been completed and results will be available by 2010. The results from SCANS 1995 and 2005 showed changes in spatial distribution. There are new estimates from T-NASS, with the Icelandic coastal stock representing 24% of the 2001 estimate. This change in occurrence of minke whales may be explained by any or all of the following: population decrease; changes in spatial distribution; possible seasonal changes in migration. However, catches are too small to be a likely cause of population reduction of this scale.

Recommendations for scientific research The Scientific Committee recommends that the sighting rate for the T-NASS Extension survey in the Norwegian Sea be calculated and used for comparison with the other T-NASS areas and previous estimates in this area. In addition, a spatial analysis of both the historical and present survey data, including the Norwegian data, should be done in order to check whether the lower occurrence of whales could be predicted to be in the areas not covered by T-NASS. Analyses of all minke data from the Greenlandic aerial and shipboard, Icelandic-Faroes shipboard and T-NASS Extension should be carried out as soon as possible. An investigation of potential changes in the ecosystem within the framework of the SC WG on Marine Mammals and Fisheries Interactions is also recommended, and body condition indices in the Barents Sea and Iceland survey data should be published when available.

The Scientific Committee underlined the importance of synoptic surveys in interpreting distribution shifts.

Greenland reported that there had been problems in catching the quota in East Greenland, which may confirm the decline of the local population, despite many fin whales. It was suggested that surveys for minke be conducted in more northern areas off West Greenland, with a further assessment in the northern part of the area which was not surveyed under T-NASS. There are presently no plans for new Greenlandic surveys, but there is a need for abundance estimates for the Upernavik-North area.

The Scientific Committee Chair recommended that hunter’s knowledge and experience be incorporated into the planning of such surveys.

Iceland noted that, according to the results from T-NASS, abundance of common minke whales on the Icelandic continental shelf area was considerably lower in 2007 than in previous surveys in the area. A partial survey conducted in 2008 showed much 68

NAMMCO Annual Report 2007 - 2008 higher densities than in 2007. These densities were similar to those from previous surveys, indicating that the year 2007 was very unusual in this respect. For this reason, a full scale aerial survey will be conducted in the summer of 2009.

Russia reported an increase number of minke whales in the Barents Sea area following surveys last year. This might be a redistribution of the whales due to climatic changes and does not necessarily mean a reduction of the population elsewhere.

Requests for advice The Management Committee recommended that the Scientific Committee be requested to conduct a full assessment, including long-term sustainability of catches, of common minke whales in the Central North Atlantic once results from the 2009 survey become available. In the meantime the Scientific Committee is requested to assess the short-term (2-5 year) effects of the following total annual catches: 0, 100, 200, 400.

4.5 Sei whales Advice from the Scientific Committee NAMMCO 16 requested the Scientific Committee to investigate the status of sei whales in East and West Greenland waters, and provide estimates of sustainable yield.

Last year, it was noted that sei whales have not been harvested in any area of the North Atlantic since the 1980’s. Although some estimates of abundance are available from the NASS, with the exception of the 1989 survey, they did not have an appropriate seasonal/spatial coverage for this species.

The Scientific Committee reported that this species is generally distributed in a more southerly range than the NAMMCO area, with unpredictable northern incursions. Very few sightings during T-NASS were recorded. More sightings were made by CODA.

In order to best address the outstanding request, the Scientific Committee recommends combining T-NASS and CODA data for analysis and that the SC Fin Whale Assessment Working Group makes a state of the art study of the existing and missing information on sei whales, as a first step to an assessment. All 2007 and older estimates should be made available to that Working Group meeting.

The Management Committee endorsed the Scientific Committee’s recommendations for how it plans to proceed in addressing the outstanding request to provide advice on the status of sei whales in East and West Greenland and estimates of sustainable yield.

4.6 Northern bottlenose whales Advice from the Scientific Committee The Scientific Committee last completed an assessment of northern bottlenose whales in 1993 and 1995. A lack of information on abundance estimates, catch data, stock structure and ecology were identified. No progress has been made since. Abundance surveys have been carried out since that time, however these do not provide a reliable 69

Report of the Management Committee for Cetaceans basis for the estimation of total abundance, as visual survey methods are not effective for this deep diving species. New distributional data may be available from T-NASS and CODA.

The Faroe Islands noted that older data, as well as some new data on the diet of bottlenose whales stranded in the Faroe Islands were being analysed. Iceland reported that their diet data had been analysed but not yet reported.

Recommendations for scientific research The Management Committee endorsed the recommendation of the Scientific Committee that analyses of data on the diet of bottlenose whales be published as soon as possible.

4.7 Long-finned pilot whales Advice from the Scientific Committee Bearing in mind that T-NASS in 2007 was expected to provide a better basis for an updated abundance estimate for pilot whales in the North Atlantic, the Scientific Committee had last year been requested to ensure that both the methodology and the coverage of T-NASS take into account the need for reliable estimates for pilot whales. In addition, priority should be given to the analysis of data on pilot whales after the completion of T-NASS. Noting that it has been over 10 years since the Scientific Committee concluded its assessment of pilot whales, the Scientific Committee had also been requested to develop a proposal for the details of a cost-effective scientific monitoring programme for pilot whales in the Faroe Islands.

The last full assessment was in 1996. It had since not been possible to follow up on all the research recommendations in the Faroe Islands nor implement a full monitoring programme. There have been decreasing abundance estimates since 1987/89 (in 1995 and 2002), although these need qualification as the survey areas have been smaller and not strictly comparable.

The methodology employed in T-NASS was designed for pilot whales as well as other key species, and the survey coverage (+CODA) is sufficient for an estimate of this species. T-NASS was planned to cover the area of the 1989 survey. The success of its implementation on each vessel is being checked during the analysis. The Faroe Islands have taken the lead in the analyses of all pilot whale data and the analysis should be available late in 2008.

The Scientific Committee convened a Working Group to develop a monitoring plan, which had worked both by correspondence and had held two meetings, the reports of which had been reviewed and endorsed by the Scientific Committee.

The main recommendations from this Working Group are outlined in a proposed Monitoring Plan to assess the continued sustainability of the Faroese catch and to include both a long-term and short-term monitoring plan to this effect (Appendix 6).

NAMMCO Annual Report 2007 - 2008

The Scientific Committee Chair explained the relative importance of the items in the monitoring plan, emphasizing that the Commission requests were a priority. However, for relatively little extra cost and effort, additional topics could supply a wealth of extra data. Finally, she noted that supporting activities were not essential but would provide wider scope to the programme.

The Scientific Committee recommended to continue the official logging of all catches (numbers of animals, sex and length) and add length at age as a new parameter; to conduct regular surveys for abundance estimates at approx. 6 yr intervals; that new abundance estimates be prioritized using T-NASS and CODA data, and that analyses of indices of abundance for all NASS/T-NASS surveys be undertaken as proposed by the Working Group; that new analyses and re-analyses of catch statistics be undertaken as a priority; that a new assessment be made when the new estimates become available; that all survey plans, assessments, data analyses of catch and biological studies be routinely presented to the NAMMCO Scientific Committee for evaluation; that an intensive short-term catch sampling programme of sex and age distribution over a 3-year period to assess variability within and between years and compare to 1986-88 sampling programme be undertaken as soon as possible; and that a standing Working Group on pilot whales be established, that would meet periodically (e.g. every few years) to examine the information.

Recommendations for scientific research The Management Committee endorsed the Scientific Committee recommendations relating to future monitoring of pilot whales in the Faroe Islands. It was, however, considered premature to establish a standing SC Working Group on Pilot Whales, before further data analysis was completed and more regular and detailed monitoring in line with the proposed programme had been established.

The Faroe Islands thanked the Scientific Committee for developing an extremely useful and pragmatic tool for the further development of sampling and monitoring of pilot whales in the Faroe Islands, not least with its clearly identified priorities and associated costs. With reference to the intensive international scientific sampling programme carried out in 1986 and 1987, it was pointed out that limited human and financial resources in the Faroe Islands do not allow for such a comprehensive undertaking on the same scale at regular intervals. A focussed 3-year programme would, however, be given serious consideration. T-NASS estimates are a first priority for the immediate future. It was also noted that it was important to continue the on- going monitoring of pollutants in pilot whales, since pilot whales caught in the Faroe Islands are one of very few species or stocks of cetaceans with a long history of contaminant sampling, and such a study was supportive of the NAMMCO focus on environmental issues.

The Faroe Islands informed the Committee that they would report back on plans and developments as soon as possible. It was noted that there had been no catches of pilot whale drives at all so far in 2008, although there have been several off-shore observations of large schools in the area during the year.

Report of the Management Committee for Cetaceans

4.8 Harbour porpoise In 2007 the Management Committee recommended that member countries conduct surveys to produce reliable estimates of abundance for harbour porpoises in their areas. In addition the Management Committee recommended that member countries provide reliable estimates of total removals, including by-catch, for this species. Once this information is available for any area, the sustainability of removals can be assessed by the Scientific Committee. This was considered particularly urgent for Greenland, where directed catches are in the low thousands annually.

Advice from the Scientific Committee In 1997, the Council (NAMMCO 7) noted that the harbour porpoise is common to all NAMMCO member countries, and that the extent of current research activities and expertise in member countries and elsewhere across the North Atlantic would provide an excellent basis for undertaking a comprehensive assessment of the species throughout its range. The Scientific Committee was therefore requested to perform such an assessment, which might include distribution and abundance, stock identity, biological parameters, ecological interaction, pollutants, removals and sustainability of removals.

In the planning of T-NASS in 2007, the Scientific Committee was requested to ensure that the coverage of the survey and the methodology would accommodate the need for estimates of harbour porpoise, especially in Icelandic waters.

In 1999 the Scientific Committee provided a general North Atlantic-wide assessment for this species through an international conference, which later led to the publication of volume 5 of the NAMMCO Scientific Publications on harbour porpoises. However this assessment was very general in nature and did not provide specific advice on sustainable harvest levels. In 2006, the Scientific Committee noted the urgent need for estimates of abundance from all areas other than those covered by SCANS-II. While records of recent directed catch are available from Greenland, there is no reliable estimate of by-catch from Iceland or Norway, although it may be considerable in these areas. Conducting an assessment requires both estimates of abundance and removals. Thus there was not at present a sufficient information base to provide advice on sustainable removals for this species for any of the NAMMCO member countries.

The SCANS 1994 and 2005 indicated the same overall abundance, but significant changes in distribution were apparent toward southern North and Celtic seas in 2005. There is a plan for satellite tagging and survey on the Faroese plateau in the Faroe Islands.

Estimates of abundance and removals are still needed in all areas for conducting an assessment. The T-NASS survey will provide an estimate for the coastal area around Iceland, and possibly also Greenland but not for other areas. Iceland implemented a special porpoise survey design and included a porpoise observer in its team. Greenland did not implement a special design but included a porpoise observer in its aerial team.

72

NAMMCO Annual Report 2007 - 2008

Recommendations for scientific research The Management Committee endorsed the Scientific Committee recommendations that Iceland and Greenland co-ordinate their analyses of the 2007 data with regard to this species, that any survey undertaken in the Faroe Islands should be designed to be compatible with the SCANS surveys, and that there should be adequate monitoring of by-catches in all areas.

Iceland underlined that harbour porpoises were included in the 2007 survey and analyses will be presented to the next Scientific Committee meeting in 2009. This will provide the first reliable abundance estimate in the Icelandic coastal area.

Greenland informed the Management Committee that a new executive government order on small cetaceans is being prepared that will include harbour porpoises, pilot whales and dolphins.

Norway reported that porpoise by-catch data will be available after validation of their by-catch monitoring programme.

4.9 White-beaked, white-sided and bottlenose dolphins Advice from the Scientific Committee The Scientific Committee has been working under a long-standing request, dating from 2001 and reiterated in 2004 (NAMMCO 10 and 13), to provide an assessment of white-sided, white-beaked and bottlenose dolphins in the North Atlantic, including direct and indirect interactions with fisheries.

Abundance estimates and stock structure information are lacking. Numerous sightings exist only for white-beaked dolphins, and occurred during T-NASS, mainly off Iceland, West Greenland, and Canada. No work has been done in Greenland, and there is little progress in Iceland and the Faroe Islands.

The Faroe Islands reported that there had been no catches in recent years.

The Management Committee noted that scientific information is still insufficient to allow for a full assessment, and reiterated its recommendation that the Scientific Committee should address the standing request as new data becomes available.

4.10 Humpback whales Advice from the Scientific Committee There has been an ongoing request for a formal assessment following the completion of the T-NASS, as well as for an investigation of the relationship between the humpback whales summering in West Greenland and other areas in order to incorporate this knowledge into estimates of sustainable yields of West Greenland humpback whales.

In addition, the Scientific Committee has been requested to assess the long-term effects of annual removals of 0, 2, 5, 10 and 20 whales off West Greenland.

73

Report of the Management Committee for Cetaceans

The 2007 estimate and older estimates have been reviewed and accepted by the IWC and have been reported to NAMMCO. The 2007 estimate, although not finally endorsed by the NAMMCO Scientific Committee, was higher than the 2005 estimate. A new estimate from T-NASS Iceland-Faroe Islands will be available in March 2009.

In 2006, the Scientific Committee advised that removals, including by-catch, of up to 10 animals per year would not harm the stock in the short or medium term. The advice which was endorsed by the Management Committee, was interim in nature, and should have been revisited once the 2005 estimate was revised and a new estimate was available for 2007. The estimate from 2007, although not final, is higher than the estimate of 2005 on which the advice was based. The Scientific Committee concluded that there was no reason to revise this interim advice until a full assessment is conducted.

Requests for advice The Management Committee reiterated the previous recommendation that the Scientific Committee be requested to assess the long-term effects of catches of 0, 2, 5, 10, 20 humpback whales off West Greenland and estimate sustainable yields for other stocks, as well as to conduct a formal assessment following the completion of the T- NASS. In addition, the relationship between the humpback whales summering in West Greenland and other areas should be investigated and this knowledge incorporated into the estimate of sustainable yields of West Greenland humpback whales.

The Management Committee endorsed the Scientific Committee’s recommendation that the humpback and sei whales be included under the Terms of Reference for the SC Fin Whale Assessment Working Group.

Proposals for conservation and management The Management Committee noted that in 2008, the Scientific Committee reconsidered its interim advice from 2006 for West Greenland humpbacks on the basis of the estimate of the survey conducted in 2007, noting that the abundance estimate was higher than that of the 2005 survey, on which the 2006 interim advice was based.

The Management Committee recommended that the total quota of humpbacks in West Greenland in 2009, including by-catches, should not exceed 10 animals.

4.11 Killer whales Advice from the Scientific Committee The Scientific Committee has a standing request for an assessment of killer whales (NAMMCO 13), including to review knowledge on the abundance, stock structure, migration and feeding ecology of killer whales in the North Atlantic, and to provide advice on research needs to improve this knowledge. Priority should be given to killer whales in the West Greenland – Eastern Canada area.

The SC Working Group to address this request last met in 1995 and concluded that while considerable progress will likely be made in the next few years, available information was still not sufficient to conduct the requested assessment. Since then, 74

NAMMCO Annual Report 2007 - 2008 there have been changes in distribution in Norway following changing in the winter distribution of herring. A few T-NASS sightings have been reported (Iceland coastal and Norwegian Sea). There are ongoing studies in photo ID and genetics in Iceland, Norway and Scotland. In 2007, the IWC review for assessment concluded there was insufficient data for assessment of this species.

The Management Committee noted that information is still insufficient to allow for a full assessment and reiterated its recommendation that the Scientific Committee should address the standing request as new data becomes available.

5. PROCEDURES FOR DECISION-MAKING ON CONSERVATION AND MANAGEMENT MEASURES

Greenland raised the issue of procedures within NAMMCO for making decisions on conservation and management measures, in particular with regard to the setting and allocating of catch limits for large whales. These questions were in part prompted by Greenland’s dissatisfaction with the decision-making process within the IWC, where Greenland’s request for a limited “aboriginal subsistence” quota of humpback whales was recently rejected. Greenland therefore urged a discussion on how to develop appropriate processes within NAMMCO for setting quotas, and proposed that the Management Committee examine existing procedures to see if any revisions or updates are necessary.

Other delegations noted that the NAMMCO Agreement was clear with respect to the mandate of Management Committees to make recommendations to their members for conservation and management measures based on the consensus of members present in the respective Committee (NAMMCO Agreement, Article 5).

It was further noted in the discussion that the way in which conservation and management measures are developed in NAMMCO is related to the nature of the utilisation of the stock in question. For example, in 1997 the Management Committee concluded that the catch of pilot whales in the Faroe Islands was sustainable, but did not propose a specific quota, as the nature of the drive hunt of pilot whales in the Faroe Islands does not warrant such a measure and the stock is only subject to direct catches in the Faroe Islands. Over all sustainable catch limits for minke and fin whales in Iceland, and bottlenose whales in the Faroe Islands, based on advice from the Scientific Committee, had also been recommended by the Management Committee in previous years. Whether and how individual member countries choose to base their national management measures on these recommendations is a sovereign decision for the country in question.

Allocation of shared stocks was, however, an issue that had not yet been fully addressed in the NAMMCO context. It was pointed out that in international fisheries cooperation, allocation is commonly negotiated through bilateral or multilateral consultations among the coastal states in whose waters the shared resources are utilised. This could no doubt also serve as a model for NAMMCO, based on total

75

Report of the Management Committee for Cetaceans sustainable catch limits for specific stocks agreed on by the relevant Management Committee.

In summary it was concluded that there was no need to make changes to the Agreement in order for NAMMCO to recommend total quotas for stocks of large whales or any other marine mammal species.

It was, however, noted that it will take considerable time for the Scientific Committee to complete work requested on methods for producing quota advice for stocks of baleen whales (see below) and that given Greenland's interest in receiving such advice in the short term, NAMMCO might consider further methods for producing interim advice on precautionary quotas, such as that already recommended for humpback whales in West Greenland (see under 4.10). The Scientific Committee Chair noted that guidelines on the duration of assessment validity and frequency of updated abundance estimates would also be required.

Requests for advice The Management Committee recommended that the Scientific Committee be requested to study general models for conservation and management of baleen whales, inter alia based on Norwegian studies presented to the Scientific Committee of the IWC.

6. RELATED MANAGEMENT ISSUES

6.1 Role of marine mammals in the marine ecosystem Incorporating: • Marine mammal - fisheries interactions • Economic aspects of marine mammal – fisheries interactions • Multi-species approaches to management

Advice from the Scientific Committee There is an ongoing request to the Scientific Committee to monitor progress made in multi-species modelling and in the collection of input data and to decide when enough progress has been made to warrant further efforts in this area. In addition, the Scientific Committee has been requested to review the results of the Icelandic programme on the feeding ecology of minke whales and multi-species modelling as soon as these become available.

The Scientific Committee has organised a number of Working Groups and Workshops over the years to address these standing requests (1999, 2000, 2001 and 2002), although the development of ecosystem modelling has taken considerable time and still requires much further work. There were new developments in ecosystem modelling in Japan and Norway. In July 2007 FAO organised a Workshop on Ecosystem Approach to Fisheries, and a forthcoming NAFO-ICES-NAMMCO sponsored Symposium, “The Role of Marine Mammals in the Ecosystem in the 21th century”, 29 September – 1 October 2008 was expected to provide an overview of

76

NAMMCO Annual Report 2007 - 2008 latest knowledge and research findings. Results from the Icelandic programme on the feeding ecology of minke whales were also expected in the near future.

The Management Committee encouraged countries and institutes undertaking such studies to continue this important work.

Greenland stressed the importance of ecosystem-based management (EBM), noting that many changes recently observed of occurrence of marine mammal and fish stocks. It is therefore very important for effective management to have a better understanding of the relationship between predators and prey and their role in the ecosystem. The Faroe Islands agreed with Greenland’s comments, and noted that there was a need for stronger scientific collaboration between fisheries and marine mammal scientists.

Requests for advice The Management Committee agreed to recommend that, in addressing the standing requests on ecosystem modeling and marine mammal fisheries interaction, the Scientific Committee should extend the focus to include all areas under NAMMCO jurisdiction. In the light of the distributional shifts seen under T-NASS 2007, the Scientific Committee should investigate dynamic changes in spatial distribution due to ecosystem changes and functional responses.

6.2 By-catch data and monitoring Advice from the Scientific Committee The Scientific Committee reported that by-catch of marine mammals likely constitutes an appreciable proportion of total removals of coastal seals, porpoises and dolphins in all areas, although there is no estimate of total by-catch (nor abundance) for many species and stocks. There has been no progress for monitoring by-catch in the Faroes, Iceland and Greenland, but by-catches are also reported as direct catch, although not systematically. In 2006, Norway implemented a by-catch monitoring system, based on reporting by selected vessels, which is presently being evaluated.

The Management Committee noted the recommendation of the Scientific Committee to organise a workshop to review the use and applicability of by-catch monitoring systems in use in different organizations, including the Norwegian monitoring system as well as to seek contact with other organizations dealing with by-catch monitoring to initiate. It was also recommended that Iceland proceeds in implementing a monitoring programme for its fleet.

The Management Committee agreed that there was need for further guidance from the Council in relation to the priority of requests and the workload of the Scientific Committee, before it could endorse the recommendation for a review of by-catch systems.

Greenland informed the Committee that by-catches of large whales and beluga and narwhals are reported. For harbour porpoises it is less certain whether the by-catches are reported as catches because the reporting of by-catch is not obligatory for this 77

Report of the Management Committee for Cetaceans species. However, this will be dealt with in the new executive government order.

6.3 User Knowledge in Management Decision-making The Management Committee agreed that the issue of user knowledge in management decision-making, while also being a general item on the Council agenda, should be included on future agendas of the Committee to allow for the presentation of relevant new information from member countries and discussion in relation to the management of specific species and stocks.

7. ELECTION OF OFFICERS

Ásta Einarsdottir, Iceland was elected as Chair of the Committee. Ulla S. Wang, Faroe Islands, was elected as Vice-Chair of the Committee.

Thanks were extended to the outgoing Chair, Halvard Johansen, for his able and consistent chairing of this Committee, and its predecessor, the General Management Committee, for the past 4 years.

8. ANY OTHER BUSINESS

Norway made an intervention on trade issues noting that cooperation through NAMMCO is based on the principle of sustainable utilisation. Economic considerations and the generation of revenues through trade in marine mammal products are an essential part of this principle. However, trade has been disrupted because of anti-whaling and anti-sealing lobbies and politically motivated trade bans, such as in relation to seal products in the EU. NAMMCO has a role to play in this situation, and member countries should continue to work actively together, as well as to be consistent in their own trade policies. The statement by Norway is contained in Appendix 3. The ICC also submitted a statement on its position regarding whaling and the IWC, which is placed in Appendix 4.

Delegations agreed that there is no valid conservation or management distinction between different types of sustainable whaling and sealing and there should be no artificial restrictions in terms of what can or cannot be traded. International trade in marine resources, including marine mammals is vital to the economies of all NAMMCO member countries.

Report of the Management Committee for Cetaceans

Appendix 3 NAMMCO – TRADE ISSUES STATEMENT BY ODD GUNNAR SKAGESTAD ON BEHALF OF THE NORWEGIAN DELEGATION

NAMMCO was founded on the principle of sustainable use of renewable natural resources: not only in the biological or ecological sense. The harvesting of marine living resources should also be economically sustainable. The industry should be viable and contribute to positive value creation. This means that trade, including international trade in whale products and seal products – as with regard to the products of other legitimate industries – should be allowed and encouraged.

That is, at least in principle. In reality there are certain unfortunate facts that we have to take into account.

In the International Whaling Commission (IWC) there is a tendency to distinguish between viz. “commercial” and so-called “aboriginal subsistence” whaling. The 1946 International Convention on the Regulation of Whaling does not recognize such a distinction – apart from its provisions (Article VIII) concerning scientific permits, the Conventions recognizes only one kind of whaling – the sustainable kind. Nevertheless in the IWC “Commercial” whaling is condemned as a sinful activity, while “subsistence” whaling is seen as somewhat more acceptable. The point of this distinction is that no commercialism i.e. no trade is supposed to be involved. One may of course pretend that it makes a difference in the moral sense if the hunter kills the animal and consumes it on the spot instead of trading the products with other people, but this is hypocritical and absurd. Such a distinction is artificial and dangerous, and should not be accepted. In my view, such a distinction between commercial and aboriginal subsistence whaling is simply wrong. In both cases we deal with human beings legitimately making a living from utilizing natural resources. What counts is whether we deal with sustainable harvesting of nature’s surplus or unsustainable exploitation of these resources.

Thus, trade is a legitimate and indeed necessary component of the sustainable use of whale resources. So, what is the problem?

The problem is that international trade has been disrupted and virtually destroyed for political reasons, as a result of the destructive activities of well-organized and articulate interest-groups – so-called environmentalists and “animal-rights” fanatics who have succeeded in creating an unholy alliance between the anti-whaling majority of the IWC and the anti-trade forces that dominate the Convention on International Trade in Endangered Species of Wild Fauna and Flora – CITES.

I do not think I need to say more with regard to the situation concerning international trade in whale products – this sad history is well known to everybody present here.

But we also know that the attacks on trade in products from marine mammals are not confined to the trade in whale products. Powerful forces are also out to destroy the 82

NAMMCO Annual Report 2007 - 2008 sealing industry. We are especially concerned at the developments in the European Union – the EU. The EU Commission has recently submitted a proposal to ban all trade in seal products – with two exceptions: (1) Products from Inuit seal hunts; and (2) Products where it can be ascertained that the hunt is conducted in a way that fulfils very strict and comprehensive condition i.e. to ensure that humane killing methods are applied, with a minimum of suffering on the part of the animal.

How these requirements are going to be implemented or practiced, we do not yet know. Obviously, we all agree that humane hunting method should be use. But we maintain that the proposed ban is in clear violation of international trade agreements, such as the GATT and WTO regulations. And there is no doubt that the ultimate aim of the trade ban is to destroy the sealing industry completely by destroying the trade. Why do I say all these things which are well known to us all?

I think it is important to underline these problems because NAMMCO has a role to play.

NAMMCO should be in the forefront of opposing any moves to introduce further restrictions on international trade in marine mammal products. We should do this as a body and as individual member countries. We should follow a clear and consistent policy in this regard wherever and whenever we encounter this problem – in global and international for a (such as the IWC and the CITES) as well as in regional fora, in our dealings with regional bodies such as the EU, and in our dealings with individual countries.

But in order to be credible, we cannot restrict ourselves to criticizing the behavior of others. If we are serious in demanding of others that they allow free and unrestricted trade in whale and seal products, we must be equally consistent in our own practices. We cannot afford to apply double standards.

So, in conclusion, I would like to remind all and every one of us to take a hard look on our own policies, and do our utmost to promote international trade in whale and seal products, bearing in mind that such trade is vitally important for the whaling and sealing industries to survive in the modern world.

Report of the Management Committee for Cetaceans

Appendix 4 STATEMENT BY AQQALUK LYNGE, PRESIDENT OF ICC-GREENLAND

• The existing management regimes in the world, in regards to hunting wildlife, especially IWC, base their quota in aboriginal and non-aboriginal whaling. • Aboriginal subsistence hunting is based on the assumption that there is no commercial connection with the distribution of the catch. • From the Greenlandic experience that distinction is too narrow, since our distribution system is more like the other North Atlantic coastal communities than those of Inuit in Canada and especially Alaska, who still practice their traditional subsistence “economy”. • ICC fully support the desire of the Greenlandic Government for a new management regime replacing IWC. The idea of NAMMCO taking over the management is also interesting to elaborate on. • The world opinion on whaling and the sealing is however based on symbolic values more than the issues. To say it clearly, the animal rights movements care about the symbolic values and certainly not the Indigenous Peoples Rights. Through the IWC they have effectively divided whaling into commercial and subsistence whaling and certainly not sustainable use of renewable resources. • There is an exemption clause about whaling in the IWC, the Aboriginal Subsistence Whaling and the same clause can be found in the US Marine Mammal Protection Act. • There is a tendency in the international fora to accept the notion that only the indigenous peoples will have hunting rights as opposed to commercial hunting. • This means for many indigenous peoples that subsistence rights and commercial hunting activities are two different issues. • For ICC and indigenous peoples’ organizations in the world it is important that governments, scientists and management organizations recognize the importance of indigenous knowledge in those issues, whether IWC continue to manage whaling or another international forum is taking over.

Appendix 5 RECOMMENDATIONS TO MEMBER COUNTRIES

Narwhal and Beluga Greenland The Scientific Committee urged Greenland to submit fully corrected estimates derived from the March 2006, August 2007 and 2008 surveys to the next meeting of the joint NAMMCO / JCNB WG. Norway Norway has for several years tried to get funding for a joint Norwegian- Russian genetics and satellite tracking study of belugas without any success. The Scientific Committee highly recommended that this project be funded.

Fin whale All countries The Scientific Committee recommended that recent indications of changes in distribution (i.e. spatial dynamics) related to environmental changes be taken into account when designing future surveys. Faroes The Scientific Committee noted that here had been no progress since the 2006 fin whale Working Group meeting in genetic analyses of the Faroese fin whale biopsy samples taken in 2000-2001. In the light of previous indications that Faroese fin whales may be very different from other N. Atlantic fin whales, the Scientific Committee urged rapid completion of the genetic analysis of these samples using techniques compatible with those used currently on Icelandic samples. Iceland The Scientific Committee welcomed the new T-NASS estimate, that it considered still as “preliminary”. It recommended that the revision and analysis identified be carried out as soon as possible. NAMMCO Secretariat The Scientific Committee requested the Secretariat to find out the outcome of the meeting of the IUCN special group meeting regarding fin whales and their status.

Minke whale All Countries The Scientific Committee recommended that a spatial analysis of both the historical and present survey data, including the Norwegian data, be initiated to check whether the missing whales could be predicted to be in the areas not covered by the T-NASS survey. Greenland, Iceland and NAMMCO Secretariat The Scientific Committee also recommended that the analysis of all the minke whale data from the Greenlandic (aerial and shipboard), T-NASS Extension and Icelandic (shipboard) surveys be analysed as soon as possible. Iceland and Norway 85

Report of the Management Committee for Cetaceans

The Scientific Committee recommended that body condition indices in the Barents Sea and Iceland be published when available. NAMMCO Secretariat The Scientific Committee recommended that sighting rate for the T-NASS Extension survey in the Norwegian Sea be calculated and used for comparison with the other T-NASS areas and previous estimates in this area.

Sei whale All countries The Scientific Committee recommended that T-NASS sei whale data be combined with CODA sei whale data for analysis. The Scientific Committee recommended making all sei whale survey data available to the fin whale assessment group.

Bottlenose whale Faroes and Iceland The Scientific Committee strongly recommended that the Faroese and Icelandic data on bottlenose whale feeding be made available as soon as possible.

Long-finned Pilot whales Faroes The Scientific Committee recommended that data from both aerial and shipboard surveys should be included in the analysis for pilot whales after being grouped and validated. The Faroes should take the lead for this analysis. The Scientific Committee recommended that calculation of new abundance estimates using T-NASS and CODA data be prioritized. The Scientific Committee recommended that work that could be started immediately before a final programme be detailed and approved, be initiated: • Calculation of indices of abundances from previous NASS surveys – 1987 and 1989, 1995 and 2001, as well as 2007. • Full documentation and statistical analysis of historic and present catch series – including length / skinn composition and sex ratio of pods. This should be undertaken as a priority The Scientific Committee recommended that all survey plans, assessments, data analyses of catch and biological studies be routinely presented to the NAMMCO Scientific Committee for evaluation.

Harbour porpoise All countries With regards to conducting an assessment (NAMMCO 7), estimates of abundance and removals are still needed in all areas. The T-NASS survey will provide an estimate for the coastal area around Iceland, and maybe Greenland but will not do so for other areas. Faroes 86

NAMMCO Annual Report 2007 - 2008

The Scientific Committee recommended that the planned survey for harbour porpoise be designed to be compatible with SCANS II and other harbour porpoise surveys. The Scientific Committee suggested that a double platform setup similar to the SNESSA survey also be used. There were also suggestions to investigate the possibility to employ an aerial survey. Greenland and Iceland The Scientific Committee recommended that Greenland and Iceland coordinate the analysis of harbour porpoise data from the T-NASS surveys.

White-beaked, white-sided and bottlenose dolphins Greenland and Norway The Scientific Committee recommended that white-beaked dolphin data from the Greenlandic aerial survey and the Norwegian shipboard survey be analysed. Iceland The Scientific Committee recommended that white-sided dolphin data from T-NASS be analysed.

Humpback whale All countries The Scientific Committee recommended that biopsies and photo-ID data from all the areas be analyzed before the initiation of a new assessment. Scientific Committee also recommended that abundance estimates for humpback whale from all surveys (2007 and older) be made available to the fin whale assessment group.

Killer whale All countries The Scientific Committee recommended that pictures taken during the T- NASS survey be made available for a cooperative study involving photo-ID and genetics, and initiated by the Marine Research Institute in Reykjavik, the University of Aberdeen and Dr Tiu Similä.

By-catch of Marine Mammals Iceland The Scientific Committee recommended that Iceland proceed in implementing a monitoring programme for its fleet.

T-NASS All countries The Scientific Committee recommends the analysis of sperm whale T- NASS acoustic data. The Scientific Committee encouraged the participants in the T-NASS surveys to prepare and make available feedback on progress in this project to the Secretariat for drafting a common press release and for updating the T-NASS web space.

87

Report of the Management Committee for Cetaceans

The Scientific Committee recommended that the publication pertaining to the general distribution of all cetaceans species throughout the entire survey area be given a high priority by all countries and that all participants forward the needed data to the Secretariat in a timely fashion. The Scientific Committee recommended that T-NASS data be transformed in a format similar to the one employed by the IWC and be archived at the NAMMCO Secretariat with the necessary clauses for use restrictions.

2.2 REPORT OF THE MEETING OF THE MANAGEMENT COMMITTEE FOR SEALS AND WALRUSES 3-4 September 2008, Sisimiut, Greenland

1. CHAIRPERSON'S OPENING REMARKS

Chair Amalie Jessen (Greenland) welcomed delegates and the observers to the Management Committee on Seals and Walruses (SMC).

Reminding the convened Delegates of the §10 of the NAMMCO agreement the Chair renewed NAMMCO’s invitation to the governments of Canada and the Russian Federation to join the Commission.

2. ADOPTION OF THE AGENDA

The agenda was adopted (Appendix 1).

3. APPOINTMENT OF RAPPORTEUR

The Secretariat was appointed as rapporteur.

4. CONSERVATION AND MANAGEMENT MEASURES FOR SEAL STOCKS

Documents referred to are listed in Appendix 2. Note that all recommendations to member countries agreed below are summarised in Appendix 3.

4.1 Harp seals The Committee noted that there was an ongoing request for advice from NAMMCO/15: to evaluate how both a projected decrease and a projected increase in the total population of Northwest Atlantic harp seals might affect the proportion of animals summering in Greenland.

Harp seals are a hunted stock with monitoring and surveys at most every 5 years. A survey in the Greenland Sea in 2007 produced data on pup production for harp seals in the West Ice. A concentration of white coats (harp seal pups) was observed for the first time in Southwest Greenland in April 2007.

Advice from the Scientific Committee The Committee noted and supported the following recommendations from the Scientific Committee: 1. A possible southward relocation of breeding by harp seals should be investigated by means of aerial surveys.

2. The Scientific Committee reiterated its recommendations (2004, 2005 and 2006): that a request concerning how a projected decrease in the total 91

Report of the Management Committee for Seals and Walruses

population of Northwest Atlantic harp seals might affect the proportion of animals summering in Greenland was to be addressed to the ICES-NAFO WG by Greenland though ICES, in time to be dealt with at the Joint ICES- NAFO WG meeting in Tromsø in August 2008. Greenland in fact raised a new concern that the population is increasing and not decreasing.

The Commission had recommended last year that Greenland take the initiative of forwarding the request of advice to the ICES/NAFO WG. Greenland informed that the request had unfortunately not been conveyed yet, but that this would be done.

3. Request for support from the NAMMCO Council to the Joint Norwegian- Russian Research Programme on Harp Seal Ecology. To this end the Joint Norwegian-Russian Fisheries Commission initiated a Joint Norwegian- Russian research Programme on Harp Seal Ecology. Full support to this programme was given at NAMMCO SC/14. However, the Russian authorities (Federal Technical Committee) refused the deployment of satellite tags in the White Sea in May both in 2007 and 2008.

Requests for advice The Committee supported the request from the Scientific Committee for NAMMCO to address a recommendation to the Russian authorities to allow the deployment of satellite tags in the White and Barents Sea in 2009 as part of the harp seal ecology study, and recommends that the Russian authorities allow the continuation of this study.

The Committee requested the Scientific Committee to establish a quota system for the common stocks between Norway and the Russian Federation and advice on Total Allowable Catches (TAC) for the management of this species be referred to the NAMMCO SC, leaving full freedom to the Committee to decide on the best methods to determine this parameter based on an ecosystem approach.

4.2 Hooded seals Status of past proposals The Committee noted that there had been a recent request from NAMMCO 16: that catches of hooded seals in the Greenland Sea should be restricted to necessary scientific catches and to satisfy local needs at roughly current levels.

Hooded seals are currently at 10-15% of the 1940s abundance, and there is monitoring and a very restricted harvest. The Scientific Committee had been requested to investigate possible reasons for the apparent decline of the Greenland Sea stock of hooded seals and also to assess the status of the stock on basis of the results from the planned survey in 2007. A survey in the Greenland Sea in 2007 produced data on pup production for hooded seals in the West Ice.

Advice from the Scientific Committee The Committee noted that the Scientific Committee’s recommendation that a request 92

NAMMCO Annual Report 2007 - 2008 be addressed to the ICES-NAFO WG regarding the declining hooded seals in the Greenland Sea had in fact been forwarded to the ICES-NAFO Working Group by Norway and has been dealt with at the August 2008 meeting in Tromsø. The report of the ICES-NAFO WG meeting and the answers to the request will be dealt with at the NAMMCO 16 SC meeting in 2009.

There were no new proposals and recommendations for scientific research nor proposals for conservation and management.

4.3 Ringed Seals The Committee noted that there were no outstanding requests and no new information to report for this species. The last assessment was carried out in 1996. Since that time there has been little progress and still very little is known on this species, mainly on behaviour.

Advice from the Scientific Committee The Committee supports the Scientific Committee’s reiteration of its previous recommendations to initiate studies for addressing the importance of pack-ice breeding seals.

There were no new proposals and recommendations for scientific research nor proposals for conservation and management.

4.4 Grey Seals Status of past proposals The committee noted the recent request from NAMMCO 16: a request for definition of management objectives in Norway.

Advice from the Scientific Committee The last assessment advice was given in 2003. Iceland had presented a management plan in 2004 and a new survey is planned for 2008. In the Faroes there is a need for immediate effort to gather better information on population, removals and breeding sites.

In response to a recommendation from the Scientific Committee for provision of data on age composition of catch, Iceland reminded the Committee that the data on age composition is owned by private parties and thus it is difficult to gather these kinds of data. Iceland will however try to obtain these data and to present them to the next meeting at Scientific Committee meeting providing that the issue of private ownership of the data is resolved.

Norway informed that a quota of 25% of the population has been established taking into consideration the estimated by-catch levels. A new population estimate for the period 2006-8 will soon be available, and a management plan, complemented by a genetic study, will be presented to the next Scientific Committee meeting in 2009.

The Faroese reported that efforts were being undertaken to obtain better information 93

Report of the Management Committee for Seals and Walruses on population, removals and breeding sites for this species, and that satellite tagging of grey seals has been attempted and is in progress.

There were no new proposals and recommendations for scientific research nor proposals for conservation and management.

4. 5 Harbour seals Status of past proposals The Committee noted a request from NAMMCO 16: to define management objectives for harbour seals in Norway, Iceland and Greenland.

There was also a request from NAMMCO 16 to the Scientific Committee: to conduct a formal assessment of the status of harbour seals around Iceland and Norway as soon as practicable.

In Iceland, new abundance estimates are available, but there is still insufficient information on by-catch. Norway implemented a system for assessment of the two coastal seal species that secures updated information about abundance approximately every 5 yr. This system has provided two abundance estimates after 1996. As a third point estimate is needed for an assessment for harbour seals another survey is needed and will probably be performed by 2010.

Advice from the Scientific Committee A first assessment by the Scientific Committee was executed in 2006 and showed that this species is at risk in all areas due to substantial decrease and / or unsustainable takes. No management plan has yet been devised in any of the countries. However, Greenland has started a research plan. In Norway, correction factors for minimum counts are under development.

The Scientific Committee considered that an assessment of the species should wait until a third abundance estimate is available from Norway and until new, reliable by- catch data, new information on multipliers (ground truthing), and the distribution of catch areas are secured. It is reasonable to imagine that the management plan will be ready by 2010. A similar timeframe will also be required for Iceland to develop its own programme.

The Committee noted the following earlier recommendations from the Scientific Committee from 2006: • More efficient monitoring of by-catch in all fisheries. • Continued and frequent abundance surveys in Norway and Iceland. • Estimation of the size of the remaining Greenlandic population. • Statement of clear management objectives in Norway, Iceland and Greenland. • Design of a plan for the Faroe Islands in case there was a re-colonisation. • That Greenland enforces a total ban on the hunt of harbour seals.

94

NAMMCO Annual Report 2007 - 2008

In addition the Committee supported the following and reiterated recommendations from the SC: • That Iceland undertakes a formal assessment of the stock and establishes clear management objectives., as well as obtains information on by-catch. • That Norway collects data on by-catch and devises a management plan. • An assessment of harbour seals should await the following: o A third Norwegian abundance estimate, including information on multipliers and distribution of catch areas. o A reliable reporting of by-catch data and age composition of takes in all areas. o An assessment should therefore be performed in 2010.

Iceland informed that a new abundance estimate is presently available, but reliable by- catch information is still missing. Furthermore, a management plan is being designed and in particular that management objectives are being defined.

Norway reported that new abundance estimates, calculated according to the recommendations of the Scientific Committee, will be carried out in 2010. At this time by-catch information from 2006 will also be available from the new by-catch monitoring programme. A management plan is expected to be completed by autumn 2008

Greenland informed that a draft of an executive order on protection and hunting of seals in Greenland is under construction and in this a ban on hunting of harbour seal is included.

There were no new proposals and recommendations for scientific research nor proposals for conservation and management.

4.6 Atlantic Walrus Status of past proposals The Committee noted two requests from Council for advice from the Scientific Committee: 1. NAMMCO 13 and 16: requested the provision of a formal assessment of the Davis Strait stock as soon as finalisation of the catch series is complete and the results from the planned 2007 survey are available; and subsequently to provide estimates of sustainable yields of the North Water and West Greenland stocks of walrus.

2. NAMMCO 15: requested the SC specifically to provide advice on the effects of human disturbance, including fishing and shipping activities, in particular scallop fishing, on distribution, behaviour and conservation status of walrus in West Greenland

Advice from the Scientific Committee Present removals were reported as likely not sustainable for the North Water and West 95

Report of the Management Committee for Seals and Walruses

Greenland stocks. The last assessment was made in 2005, but it was incomplete because of the lack information on stock delineation and abundance information. A revised corrected catch series (including “struck-and-lost”) was also needed.

Considerable progress has been made on catch series in all areas and most items. Results are planned for December 2008, but no progress has been made in improving the old catch series (up to 2006) for Greenland.

The hypothesis of a common stock of walrus between Canada and Greenland has been “confirmed” (West Greenland walruses have been observed wintering in eastern Baffin Island).

New data are anticipated in the summer 2009 on survey and tagging in the North Water, and a survey in East Greenland.

Regarding the assessment of West Greenland-Eastern Baffin Island stock, there would be sufficient new data by the end of 2008/09, but not before, so that a WG could not be convened to make the assessment.

No progress was reported on the subject of human disturbance on West Greenland walrus.

Requests for advice The Committee supported the Scientific Committee’s recommendations for a new assessment which was feasible either as : 1. An assessment of West Greenland-Eastern Baffin Island only (due early 2009, before the SC meeting); or 2. A full assessment of North Water, West Greenland-Eastern Baffin Island and East Greenland (due late 2009 or early 2010). Greenland underlined the need to complete the full assessment before late 2009, and therefore requested the Scientific Committee to provide a full assessment (option 2.) in time for the establishment of quotas. The Committee recommends that the Greenlandic authorities make sure the researchers from the Greenland Institute of Natural Resources (GINR) are aware of this request.

There were no new proposals and recommendations for scientific research nor proposals for conservation and management.

5. PROCEDURES FOR DECISION-MAKING ON CONSERVATION AND MANAGEMENT MEASURES

This item was discussed in a joint session with the Management Committee for Cetaceans and is to be found in the report of that Committee (Section 2.1, Item 5.).

6. RELATED MANAGEMENT ISSUES

96

NAMMCO Annual Report 2007 - 2008

Items 6.1 and 6.2 were discussed in a joint session with the Management Committee for Cetaceans and are to be found in the report of that Committee (Section 2.1, Items 6.1 and 6.2).

6.3 User Knowledge in Management Decision-making The Committee agreed to disband the Working Group on User Knowledge and to reconsider the issue for the next meeting (during NAMMCO 18).

7. TRADE ISSUES AND THE EU PROPOSAL ON BAN OF IMPORT OF SEALSKIN

In 2008 the European Commission resolved on a ban on the import of sealskin. The case has been ongoing since January 2006 with a long series of meetings and hearings.

It was underlined that NAMMCO is a management body and not a lobby organization. NAMMCO member countries share views on management resources, scientific approach to management and on sustainable use. Thus ideally NAMMCO should lead by example as a management body (i.e. by publicising work such as the activities of the Committee on Hunting Methods). It was stressed that the proposed ban was not taken as a conservation and management measure.

However, the SMC expressed their serious concerns about the implications that such trade barriers can have on the responsible management and sustainable use of abundant seals stocks across the North Atlantic, and the economies of the many communities dependent on these resources.

Statement by the ICC: Aqqaluk Lynge, president of the ICC-Greenland, presented a statement which can be found as Appendix 4 of the Report of the Management Committee for Cetaceans (Section 2.1). The reference therein to hunting and world perception of hunting rights was also of relevance to sealing.

8. ANY OTHER BUSINESS

Sealing Symposium Norway reported on the Norwegian-Russian Symposium in Tromsø, 25-26 August 2008, on Prospects for Future Sealing in the North Atlantic. The programme included several presentations from Norwegian, Russian and other sources, including: • Status and management of harp and hooded seals in Canada • Russian hunt and prospects • New Russian boat approach • Management objectives for the Norwegian seal hunt • Greenland Sea sealing • KNAPK view on sealing • Traditional products from the seal hunt: status and prospects • Seal oil and contributions to human health 97

Report of the Management Committee for Seals and Walruses

• Report from the Vaasa Seals and Society conference (October 2007) • Sustainable harvest of marine resources: should seals and fish be treated differently? • Implications for the trade ban • Anti-sealing: who are they? • Future of sealing in the North Atlantic. A published report will follow.

The SMC commented that this Tromsø Symposium was originally thought to be limited to Norway and the Russian Federation, but it has become an international event. It is a very interesting forum and it is useful for the collaboration on commercial and scientific interests between the two countries and among the other participants. It is a good platform for understanding the problems of sealing, and for this reason, meetings like this one should be held again in the future.

Statement by KNAPK A hearing among the local members has resulted in new information on harp seals and reproduction. KNAPK hopes that user knowledge can be used in management of all seals. In particular harbour seal hunting levels are presently very low: the decline in numbers is surely due to some other factor than hunting. The full statement is found as Appendix 4 to the main Council Report in Section 1.1.

9. CLOSURE OF THE MEETING

There were no other matters for consideration, and the Chair thanked the Scientific Committee Chair and all participants to the meeting and declared the meeting closed.

The draft report was approved, and the final version was agreed upon by correspondence.

Appendix 3 RECOMMENDATIONS TO MEMBER COUNTRIES

Harp seals Greenland In 2005, the Council requested an evaluation on how a projected decrease in the total population of Northwest Atlantic harp seals might affect the population of animals summering in Greenland.

The Scientific Committee reiterated its recommendation that ICES-NAFO Working Group be asked to address this request, as a first step. The SC urged Greenland to forward this request to the ICES-NAFO Working Group on Hoods and Harps as soon as possible, so this matter could be dealt with at the next meeting in late August 2008. Norway The Scientific Committee recommended flying reconnaissance surveys (e.g. south of 67°N in East Greenland) to investigate the possible presence of whelping patches in “untraditional” areas, to continue the sampling for biological parameters, and the characterization of stock identity.

Ringed seal Greenland and Norway The Scientific Committee reiterated its recommendation for initiating studies on ringed seals on sea ice in offshore areas, for addressing importance of pack-ice breeding, especially in the present context of climatic changes and subsequent changes in ice condition and cover.

Grey seal Faroes The Scientific Committee reiterated its recommendation that immediate effort be undertaken to obtain better information on the nature and impact on the take in the Faroes, and to obtain information on breeding sites. Iceland The Scientific Committee recommended Iceland to make available the new data on age composition of the catch. Norway The Scientific Committee reiterated its recommendation on the quota level in Norway, estimated non-sustainable, but commended that a management plan was on its way and recommended that it should be presented to NAMMCO for evaluation.

Harbour seal Greenland The Scientific Committee reiterated its recommendation of a total ban on hunt for this species. Iceland

101

Report of the Management Committee for Seals and Walruses

The Scientific Committee reiterated its recommendation for a formal assessment of the stock and the establishment of clear management objectives. It also renewed its recommendation from the last meeting about collecting information on the by-catch. Iceland and Norway The Scientific Committee recommended that both countries ensure better information on by-catch and on the proportion of direct catch and by-catch and their age composition.

Walrus Greenland The Scientific Committee reiterated its recommendation that progress be made on the old catch series, which accounts for takes up to 2006. This needs to be done, since the data are required for a reliable assessment.

3.1 REPORT OF THE FIFTEENTH MEETING OF THE NAMMCO SCIENTIFIC COMMITTEE

EXECUTIVE SUMMARY

The 15th Annual Meeting of the NAMMCO Scientific Committee (SC) was held in Qeqertarsuaq, Greenland, 11-14 April 2008. There were observers from Japan and the Russian Federation.

The following are summaries by agenda point as used in the main report.

6. ROLE OF MARINE MAMMALS IN THE MARINE ECOSYSTEM

6.1 Update on the Dartmouth conference (Sep/Oct 2008) An update was given on the upcoming conference co-sponsored by NAMMCO (20,000 NOK) on “The Role of Marine Mammals in the Ecosystem in the 21st Century” in Dartmouth (Canada) 29 September – 1 October.

6.2 Update on progress on modelling The report of the NAMMCO observer on the FAO workshop on Ecosystem Approach to Fisheries was presen ted. Some definitions of best practice were outlined which NAMMCO may choose to include in its ecosystem model work.

6.3 Working Group on Marine Mammal – Fisheries Interactions The NAMMCO SC recommended reviving the Working Group (WG) on Marine Mammals and Fisheries interactions in view of recent progress in the field. In light of the new survey results, the SC recommended that the WG expand its terms of reference to include all areas under NAMMCO jurisdiction and investigate dynamic changes in spatial distribution due to ecosystem changes and functional responses. The SC recommended that this WG hold a meeting before March 2009 and that work includes a review of the Icelandic programme on the feeding ecology of minke whales and multi-species modelling.

6.4 Icelandic programme on the feeding ecology of minke whales Iceland presented preliminary results from the research programme on the feeding ecology of minke whales which significantly correct the prey composition data input to the model presented to ICES.

6.6 Other matters Norway and Russia have expressed concerns over the current size of the Atlantic harp seal populations and their predation on fish stocks. A project on the ecology of this species has been initiated and adopted by the Joint Norwegian-Russian Fisheries Commission. However, the Russian authorities have so far refused permission to deploy satellite tags in the White Sea. The SC highly recommended that the Russian Federation issues permits for this tag deployment, which should deliver the key information for assessing the ecological role of harp seals. 105

Report of the Scientific Committee

7. SEALS AND WALRUSES STOCKS - STATUS AND ADVICE TO THE COUNCIL

7.1 Harp seal • Results from aerial surveys carried out in spring 2007 to estimate abundance and pup production for harp and hooded seals in the Greenland Sea are being analysed. Only scattered hooded seal whelping was observed while both patch and scattered harp seal whelping were observed. Meanwhile a concentration of white coat harp seals were observed for the first time in southwest Greenland. The question was whether changing in ice condition might have triggered behavioural changes such as some relocation of breeding. This would have implication for future research and management. • The historical Barents Sea/White Sea population has been assessed to up to 6 million in 1875. Aeroplane surveys conducted by the Russian Federation in 2004 and 2005 indicate a decrease in pup production confirmed by similar surveys conducted in 2006 and 2007. A temporal and geographical reduction in ice cover in these two periods might be accounted for this decline. • The Committee recommended an investigation of the possible presence of whelping patches in “untraditional” areas, to continue the sampling for biological parameters, and the characterization of stock identity. • With regards to the question of how a projected decrease in the total population of Northwest Atlantic harp seals might affect the proportion of animals summering in Greenland, the Committee reiterated its recommendation that the ICES-NAFO Working Group be asked to address this request. The Committee urges Greenland to forward the request as soon as possible, so it could be dealt with at the next meeting in late August 2008.

7.2 Hooded seal • Satellite tagging of seals in the Greenland Sea in 2007 and 2008 shows extensive use of all of the North Atlantic. Similar tagging off Southeast Greenland in 2007 shows movement to the Davis Strait and the Labrador Newfoundland coast. • The Committee recommended in 2006 that catches in the Greenland Sea be restricted to necessary scientific catches and to satisfy local needs at roughly current levels. This should be accompanied by a monitoring programme. This recommendation was to be revisited after the results from the 2007 survey became available. These results were not available yet, it was noted, however, that no whelping concentrations were detected but only scattered whelping. This would increase the uncertainty of the pup production estimate. The question of possible alternative whelping patches (see under 7.1) was also crucial. • With regards to the possible reasons for the apparent decline of Greenland Sea stock of hooded seals, and the assessment of the status of the stock on basis of the results from the 2007 survey, the Committee recommended that the ICES-NAFO Working Group be asked to address this request and was informed that Norway had already forwarded the request. 106

NAMMCO Annual Report 2007 - 2008

7.3 Ringed seal The Committee reiterated its recommendation for initiating studies for addressing the importance of pack-ice breeding seals, especially in the present context of changes in ice condition.

7.4 Grey seal • Abundance estimates for the Norwegian coast will be available in 2008 and will be complemented by a survey of the breeding colonies of the Murman Coast. • Preliminary results from a Norwegian genetic study of all the North Atlantic areas have identified subdivisions with very little overlap that confirm data from conventional tagging experiments. • The SC noted again that Norwegian quota levels were not sustainable and recommended that the Norwegian management plan be submitted to NAMMCO for evaluation. • The SC reiterated its recommendation that the Faroes undertaken immediate efforts to determine the impact of the takes and to identify breeding areas. • A survey is planned for 2008 in Iceland. The SC recommended Iceland provide data on the age composition of the catch. • The SC recommended that a grey seal WG meeting be held in 2009.

7.5 Harbour seal • Greenland has started implemented the monitoring programme recommended in 2006 and has implemented an improved reporting system leading to more realistic catches of under 100 animals a year. • The SC commended the implementation of the monitoring programme but reiterated the recommendation for a total ban on this hunt in Greenland. • A survey in Iceland in 2006 confirmed the 2003 estimate. Catches have declined, but there is insufficient information on by-catch. The SC reiterated the recommendation for the establishement of management objectives in Iceland and the collection of information on by-catch and age composition of the catch. • Norway has implemented a system for assessment of coastal species, including harbour seals, (with regular surveys), and is working on a management plan for these. By-catch information are gathered under the new by-catch monitoring system. • With regards to conducting an assessment of the species in Norway and Iceland, the Committee recommended waiting until the 2010 Norwegian abundance estimate. This time frame would ensure adequate time to gather reliable information on by-catch and age distribution of the catch in both areas and for Norway to develop multipliers for transforming minimum count • to total abundance estimate.

7.6 Walrus

107

Report of the Scientific Committee

• There has been no progress with regards to advice on the effects of human disturbance on distribution, behaviour and conservation status in West Greenland. However, cameras have been deployed at haul-outs in Svalbard to investigate the influence of tourism, which could provide some answers. • The old Greenlandic catch series for takes, up to 2006, have not been revised as recommended. New abundance estimates are available for 2006 for West Greenland and for 2006 and 2007 for South East Baffin Islands, and satellite tags were deployed in 2006 in Central West Greenland (CWG). A new survey is planned for the North Water area in 2009. • New abundance estimates and historical sex ratio are available for the Svalbard area. • Satellite tagging in CWG and individual recognition of hauled-out animals confirm the hypothesis of a common stock between Greenland and Canada. • With regards to conducting an assessment of walruses and providing estimates of sustainable yields of the North Water and West Greenland stocks of walrus, the Committee recommends an assessment meeting for the West and North Greenland stock as soon as possible while an assessment for the East Greenland should await the results of the 2009 survey in East Greenland.

8. TRANS NORTH ATLANTIC SIGHTINGS SURVEY

8.1 Reports from meetings Planning The third planning meeting was held in St. Andrews, Scotland, 30 March - 1 April 2007. Agreement was reached upon a) the general strategy for coverage and the survey general design (boundaries, stratification, effort allocation), b) the survey protocols (survey mode & procedure) for the aerial surveys and the shipboard surveys (Iceland/Faroes, Greenland, T-NASS extension) as well as the rules for adapting these protocols if needed, c) the training required for cruise leaders and observers especially for shipboard surveys (new procedures for Iceland/Faroes), d) the task to be completed and the responsible actors, e) the necessity and means of contact and coordination during the survey (between the platforms and with the Secretariat), f) a strategy for dissemination of information.

Evaluation • T-NASS coordination during planning provided many advantages over uncoordinated or less coordinated national surveys, and is expected to provide similar advantages in the analysis of large scale data. • Such a large scale synoptic coverage provides a useful snapshot overview of the spatial distribution and abundance of species. • Cooperation with CODA and SNESSA had been very positive. • The WG concluded that coordination had been successful and had led to both the first trans-Atlantic survey and also the first complete synoptic coverage of the northern North Atlantic. It recommended continued cooperation in coordinating the output from the T-NASS project.

108

NAMMCO Annual Report 2007 - 2008

Working group on Abundance Estimate • Preliminary analyses were presented and discussed for fin, minke and humpback whales. Preliminary results were reported for pilot whales and harbour porpoises, as well as some other non-target species and plans were made for analysis. Specific results would be considered under the relevant stock. • A strategy for coordinated analysis and publication of the results with CODA and SNESSA was discussed. In particular it was agreed that the three surveys would publish as a priority a joint primary publication pertaining to the general distribution of all cetaceans species throughout the entire survey area, under the leadership of the T-NASS coordinator and the NAMMCO Secretariat. • The need for a proper archival of T-NASS data, was underlined.

9. CETACEANS STOCKS - STATUS AND ADVICE TO THE COUNCIL

9.1 Fin whale • Stock delineation: older and newer genetic analyses support the lack of genetic divergence for fin whales across the North Atlantic. The Committee urged rapid completion of the genetic analysis of the Faroese biopsy samples, said to be genetically different, with techniques compatible with those used on Icelandic samples. • Relatedness: work is in progress with this newer more sensitive analysis method. • Estimates from T-NASS: the 2007 figure of 20,644 (95% CI:15,053-26,540) from the Icelandic shipboard survey is not significantly different from that in 2001, however this figure was still preliminary and needed to be revised. The Greenlandic figure of 4,660 (95% CI: 1,890-11,500) was higher then the 2005 estimate. The Norwegian estimate will be available in the course of the year. • Russian Federation: there has been an increase in the frequency of sightings in the Barents Sea in August-September. • Faroes: a catch statistics database for the North Atlantic is under compilation and will be deposited at the NAMMCO Secretariat. • New requests and future work: the Committee recommended that recent changes in distribution be taken into account in the design of new surveys. It recommended that the assessment of Northeast Atlantic stocks, including the central stock, be initiated as soon as the 2007 estimates are finalised and before the next SC meeting.

9.2 Humpback whale • Revised Greenlandic 2005 estimate: this estimate was not presented in a NAMMCO forum and therefore not discussed. • New estimates from T-NASS: the 2007 estimate was still considered preliminary. • Review of the advice on catch limit for West Greenland given in 2006: although preliminary, the 2007 estimate was higher than the 2005 estimate, 109

Report of the Scientific Committee

and there is no immediate indication of a population decrease. The SC did not see any reason to reconsider the 2006 interim advice until a proper assessment is conducted. • New requests and future work: with regard to an assessment of North Atlantic stocks, the Committee recommended that biopsies and photo-id data from all areas should be analyzed before such an assessment. The SC agreed that a joint assessment with the IWC was not helpful, and recommended as a first step, that the fin whale assessment group evaluates the data available.

9.3 Sei whale • New estimates from T-NASS: a new estimate would present a large confidence interval due to the paucity of sightings. The Committee recommended that T-NASS sightings be pooled with CODA’s for a joint analysis. • Update on research in NAMMCO countries: the 2005 Greenlandic estimate was not formally accepted. The estimates from NASS gave a minimum figure. • New requests and future work: with regards to a status in East and West Greenland waters, the SC recommended making all sei whale data available to the fin whale assessment group for evaluating the available information and providing a state of the art estimate.

9.4 Minke whale • Update on stock delineation and relatedness: Norwegian and Icelandic genetic studies show very little genetic differences across the North Atlantic. • New estimates: o Iceland from 2007: 10,680 (95% CI: 5,873-17,121) from the original blocks including all observers; 15,055 (95% CI: 6,357-27,278) including only experienced minke whale observers. The point estimate shows a decline of 24% since 2001. There is no evident reason for this decline. Natural mortality of such a scale was unlikely, and catches were too small to account for the decrease. The most likely explanation was ecological, with the whales being elsewhere at the time of the survey. There have been significant shifts in prey distribution around Iceland in recent years. o Norway: evidence of large annual changes in distribution in the period 1952-1980. o Comparison of SCANS surveys 1994 with 2005 also reveals significant changes in spatial distribution. • Update on progress: the Icelandic research programme was completed in 2007 and samples are being analysed. Results are expected in 2010. • Future work: the Committee recommended several analyses for a understanding the situation: o Sighting rate from T-NASS Extension surveys in the Norwegian Sea (not covered by a dedicated survey) should be calculated and compared with other T-NASS areas and previous estimates.

110

NAMMCO Annual Report 2007 - 2008

o A spatial analysis of both the historical and present surveys, including the Norwegian mosaic survey, should be undertaken, to identify parameters that could explain/predict spatial distribution. o The analysis of remaining T-NASS minke data should be given priority: Greenlandic (both aerial and shipboard), Extension and Icelandic/Faroese shipboard. o Potential changes in the ecosystem should be investigated within the framework of the WG on Marine Mammals and Fisheries Interaction.

9.5 Narwhal & 9.6 Beluga • Update on 4-year Greenlandic research programme and other progress: o New survey results existed or were on their way for 2006 and 2007, incl. for the Melville Bay and Inglefield Bredning areas, but where not presented. The plan for the 2007 survey had not been reviewed by the SC or the T-NASS Planning Group, despite the request of the Commission to do so. o 10 narwhal were satellite tagged in 2007 in North and West Greenland. o An aerial survey was planned in summer 2008 in East Greenland. o Tagging of beluga was planned in West Greenland in 2009. o In the north Water area surveys for narwhal, beluga and walrus are planned for 2009. o A genetic study indicates clear separation between the Greenland and Svalbard belugas. o With regards to the assessment of narwhal and beluga, the SC considered that there were enough new data to warrant an update of the assessments and recommended a meeting of the Joint JCNB/NAMMCO WG before March 2009 to allow the use of the assessment in setting the new quota series. • Future work: o An age determination workshop is needed and the Joint WG was asked to consider its organisation. o The SC recommended that the joint Norwegian-Russian genetics and satellite tracking study be funded. o The Greenlandic quotas for narwhal and beluga were reviewed. The Committee noted that these are still much above the levels it recommended of 100 belugas (2000 & 2001) and 135 narwhals (2003) for West Greenland and expresses continued concern about the quota level. At the same time the SC recognizes that new preliminary abundance estimates are higher than previous estimates. The Committee stresses the importance for Greenland to submit fully corrected estimates from 2006, 2007 and 2008 surveys to the next Joint WG meeting.

9.5 Bottlenose whale • Update on progress: There has been little progress made, but some distribution data may come from T-NASS and CODA.

111

Report of the Scientific Committee

• Future work: The Committee recommended that Icelandic and Faroese data on feeding be published as soon as possible.

9.6 Killer whale Although changes in distribution have been noted in several areas, and a few sightings made during T-NASS, data are still too sparse, especially in the West Greenland- Eastern Canada area, to warrant an assessment.

9.7 Pilot whales • New estimates from T-NASS and CODA: data from both the shipboard and aerial surveys should be included in the analysis. • Monitoring programme for the Faroes: a WG meeting was held prior to the SC meeting defining the main terms of the programme. A second WG meeting is scheduled to take place in July 2008 to define the details of the programme. • New requests and future work: o Calculation of new abundance estimates from T-NASS and CODA data. o Presentation of all survey plans, assessment, data analyses and catch and biological studies should be routinely presented to the SC. o Establishment of a standing WG.

9.10 White-beaked, white-sided dolphins and bottlenose dolphin • Update on progress: T-NASS and CODA may generate an abundance estimate for white beaked and white sided. However an assessment is not warranted for any of the species yet, due to the slow or absent progress in most areas. • Future work: o T-NASS data should be analysed, incl. from Greenlandic aerial and Norwegian surveys . o Satellite tagging of white-sided dolphins is planned in the Faroes. o The Faroese programme on the biology of white-sided dolphins is in the analysis stage.

9.11 Harbour porpoise Estimates from T-NASS: o Iceland as well as Greenland to a lesser extent, have implemented modifications in their survey designs to accommodate this species, as requested by the Council. This will lead to the first reliable abundance of harbour porpoises in Icelandic coastal area. o The Committee recommends that Iceland and Greenland coordinate the analysis of these data. • Future work: o Satellite tagging and a dedicated survey is planned in the Faroes in the next years. o The Committee recommended that this survey be designed to be compatible with SCANS II and other harbour porpoise surveys. 112

NAMMCO Annual Report 2007 - 2008

o With regards to conducting an assessment, estimates of abundance and removals are still needed in all areas. T-NASS will generate an estimate for the coastal area around Iceland and maybe Greenland, but will not do so for other areas.

10. BY-CATCH OF MARINE MAMMALS

Update on monitoring progress • Iceland and Faroes: no progress since the last meeting. • Norway: a new monitoring system had been implemented in 2006. It is under evaluation and validation, especially the extrapolation of recorded to total by-catches. • Greenland: no system for reporting by-catches is in place. They should be counted as catches, although this is not mandatory.

New requests and future work • As a first step to handle by-catch issues, the SC recommends the organisation of a workshop to review the use, applicability and validity of by-catch monitoring systems, including the Norwegian monitoring system. • The Committee recommends that Iceland proceeds in implementing a monitoring programme for its fleet.

11. PUBLICATIONS

• NSP 6 – Grey seals: published and distributed in 2007. • NSP 7 – NASS: ready for publication later in 2008. • NSP 8 – Harbour seals: about 30 papers are expected, with June 30, 2008, as deadline for submission. Publication is expected early 2009. • Other publications: a unified publication of T-NASS results, together with CODA and SNESSA has been welcomed by the participants to the projects. IWC has already proposed its Journal. The SC recommended investigating the possibility of a joint Journal of Cetacean Research and Management- NAMMCO publication.

13. FUTURE WORK PLANS

The Scientific Committee welcomed these presentations from the representatives of Japan and the Russian Federation.

4.2 Working Group Reports The four Working Group Reports available to the meeting were the following: • T-NASS (2) • Abundance Estimates • Pilot whales

4.3 Other reports and documents Several other reports and documents were presented to the meeting.

5. COOPERATION WITH OTHER ORGANISATIONS 115

Report of the Scientific Committee

5.1 IWC The 59th meeting of the Scientific Committee (SC) of the International Whaling Commission was held in Anchorage, Alaska from 7-18 April 2007. Lockyer attended as observer for the NAMMCO Scientific Committee. It was noted with regret that no IWC observer is present at this meeting. Lockyer reported the following items that were considered of interest to NAMMCO.

The SC again considered mechanisms for the implementation of the RMP, which cannot be concluded until work on MSYR has been completed. There were a number of recommendations with respect to N. Atlantic fin whales to be considered at the First Intersessional Workshop (has since been held in April 2008 prior to the NAMMCO SC): regarding matching various photo-identification catalogues and holdings throughout the N.Atlantic and Mediterranean; making available catch series and genetic analyses; starting implementation procedures now that priority Bryde’s whales have been completed. Regarding Central and Northeastern Atlantic minke whales, the implementation review might be completed in 2008 or 2009, and a steering group was set up to prepare for the review.

The SC reported on by-catch monitoring schemes required by the EU starting in 2006, although it was unclear if all national reports had been submitted. Such reports would be considered by the EU in late 2007 followed by an ICES review. The SC noted the CMS initiative - Strategic Implementation Plan 2006-2011 - aimed at reviewing impacts and threats through global commercial and artisanal fisheries on migratory species. The SC recommended close coordination between IWC and CMS.

Under Aboriginal Subsistence Whaling Management Procedure (AWMP), new information from the Greenland Research Programme came under scrutiny. The SC stated the importance of these research efforts in developing AWMP Strike Limit Algorithms (SLAs). Regarding abundance and trends, the SC accepted the bias- corrected cue-counting abundance estimate for W. Greenland minke whales of 10,800 (.95 CI: 3,600-32,400) in 2005, which could be used for assessment purposes. The bias-corrected line-transect abundance estimate of W. Greenland fin whales of 3,200 (.95 CI: 1,400-7,200) was acceptable and considered well above MSYL and could be used for assessment. A new assessment for fin whales was available in 2007, and was accepted for providing interim management advice. The SC recommended assessments be made for W.Greenland minke whales at an intersessional workshop so that a final assessment could be accepted at the 2008 IWC meeting.

The SC strongly recommended that the IWC adopt the Aboriginal Subsistence Whaling Scheme (AWS) that covered a number of practical issues relating to survey intervals, carryover and guidelines for surveys. The SC welcomed further aerial and shipboard surveys to be undertaken off W.Greenland as part of T-NASS, and anticipated new abundance estimates in 2008.

The SC included a consideration of a request from Denmark for management advice on other large whales off W. Greenland, notably bowhead and humpback whales. However, it was unable to endorse any assessment on humpback whales although the 116

NAMMCO Annual Report 2007 - 2008 abundance estimate available was considered an under-estimate, and no management advice was provided at this time. As for bowhead whales, the SC recognised a single Eastern Canada – W. Greenland shared stock in the eastern Arctic, based largely on satellite tracking results in 2005 and 2006. It accepted an agreed estimate of abundance of 1,230 (.945 CI: 500-2,940) for over-wintering bowheads off W. Greenland. The SC urged that there be a new assessment of this species at the 2008 IWC meeting.

The SC noted the Norwegian report of bowhead sightings in the Fram Strait between Svalbard and Greenland, and recommended a continuation of surveys to increase knowledge of these animals.

With respect to environmental concerns, the SC reported an increased occurrence of the effects of harmful algal blooms (HABs) on cetaceans. The SC recommended the establishment of a Cetacean Emerging and Resurging Diseases (CERD) WG which should report to the 2008 meeting. The SC reviewed a report from the POLLUTION 2000+ project, which recommended a second phase. This was endorsed, and this second phase will address an integrated modelling framework for examining the effects of pollution in cetaceans, and develop a protocol for validating biopsy samples in pollution-related studies.

The SC considered and endorsed a plan for an Intersessional Workshop on Climate Change, and set up a steering group in preparation.

Although small cetaceans are not a subject for management advice in the IWC, the SC nevertheless undertook a worldwide review of killer whales in 2007. Sightings information (1970 - 2007) from the northeast Atlantic indicated a relatively even summer distribution across the north-eastern Atlantic. A range of estimates of abundance (4,413 - 26,774) were derived from NASS surveys in different years, and an abundance estimate of 606 (.95 CI: 460-800) was available from 2003 for coastal northern Norway, based on photo-identification. It was noted that genetic analyses on stock structure are currently underway in the UK and Norway. Finally, a new method for determining age (with accuracy +3.8yr) was reported, using specific fatty acid profiles in outer blubber of killer whales. This method may well be useful in examining age in other species where age methods are as yet uncertain.

The SC noted annual takes of 15 – 34 killer whales between 2005 and 2006 off W. Greenland. In addition, annual takes of harbour porpoises (2,568 in 2005) and long- finned pilot whales (91 in 2005) raised concerns about sustainability off W. Greenland, and the SC recommended formal assessments for these species and stocks.

Progress on the Icelandic Research Programme for minke whales was reviewed under Scientific Permits.

In summary, SC priorities for 2008 include implementation procedures for N.Atlantic Fin and minke whales, and work under the AWMP for development of SLAs for Greenlandic whales. 117

Report of the Scientific Committee

5.2 ASCOBANS There was no official observer either at the 14th or the 15th meeting (just held in April 2008). Ongoing conservation of harbour porpoises in the Baltic and the North seas, where up to 50% strandings were catch related. There is presently no harmonized reporting system. ASCOBANS is considering to come under the umbrella of ICES for by-catch reporting. The use of “pingers” to mitigate by-catch has become mandatory in the EU in certain fisheries. Trials of different type of nets to make them visible to porpoises were reported with mixed success. A draft guideline for use in reporting fisheries effort in relation to by-catch was drafted by ASCOBANS. Pollution, underwater sounds and disturbance were reported upon, and incidents of collision with high speed ferries. Work is ongoing into problems with cetacean hearing pathologies and fatalities related to military operations and munitions. Concern was expressed over controls on oil production pipeline construction as in the Russian pipeline in the Baltic. It was noted however that OSPAR already has guidelines for construction of these structures. A westward extension of the Agreement area to the west of Biscay and to the western side of the UK in the North Atlantic was in the process of ratification in 2007. The Secretariat will endeavour to find out if this has since been fully ratified1.

5.3 ICES and NAFO Haug reported the activities of ICES in 2007. The ICES Working Group on Marine Mammal Ecology (WGMME) met 27-30 March 2007 in Vilm, Germany, to review any new information on population sizes, by-catches and mitigation measures for fisheries that have a significant impact on small cetaceans and other marine mammals. Additionally, so far as it was possible, the working group summarized the planned observations to meet requirements of EU Regulation 812/2004 (implementation of onboard monitoring schemes and observers to monitor and estimate the scale of by- catch of marine mammals in certain fisheries) by ICES area member state for 2007. The working group also reviewed and reported on the preliminary results of the SCAN II project, for which new surveys were carried out in 2005. In addition to contribute to the development of survey methodology, the project provided the first comprehensive estimates of abundance of small cetaceans in the whole west European Atlantic continental shelf region. Also, SCANS II is relevant with respect to the development of a framework for management of by-catches. Furthermore, WGMME summarized the current status of the planning of a workshop on marine mammal health - the workshop is intended to be held in Liége, Belgium, in 2008. Finally, WGMME assessed information on how changes in hydrodynamics and sea temperature affect changes in the distribution, population abundance and condition of marine mammals, the main conclusion being that pagophilic species such as polar bears and ice breeding seals will be the most likely species to be impacted by an increase in sea temperature.

The 2007 ICES Annual Science Conference (ASC) was held in Helsinki, Finland, 17- 21 September 2007. Several ICES committees (e.g., Living Resource Committee and Marine Habitat Committee) deals with marine mammal issues. Thus, both present and

1 This has now been ratified. 118

NAMMCO Annual Report 2007 - 2008 future theme sessions at the ASC are designed with marine mammals included as an integral part. Relevant sessions at the 2007 ASC were: • Theme session D (“Comparative marine ecosystem structure and function: Descriptors and characteristics”): The variable role of important marine mammal species was assessed in several presentations aimed to give integrated characterizations and comparisons of different ecosystems of the northern hemisphere. • In theme session I (“Effects of hazardous substances on ecosystem health in coastal and brackish-water ecosystems: Present research, monitoring strategies, and future requirements”), results were presented from impact studies of white whales (beluga) and harbour seals. • Theme session L addressed the issue “Stock identification – applications for aquaculture and fisheries management”. Work was presented that addressed questions related to minke whale and grey seal stock structure using genetic (DNA) analyses. • Both theme sessions O (“Flying outside the ICES assessment WG paradigm – alternative approaches to providing fisheries management advice”) and R (“The ecosystem approach: What’s the impact on marine science, science- based advice, and management of marine ecosystems”) included presentations relevant to the management of marine mammals.

Upcoming theme sessions, relevant to marine mammal issues, intended for the ASC, 22-26 September 2008 in Halifax, Canada, include, but may not be restricted to: “Role of sea ice in polar ecosystems”, “Comparative dynamics of populations in the Baltic Sea and Gulf of St. Lawrence ecosystems” and “New methodology for tracking fish, mammal and sea bird behaviour and migrations”.

5.4 Canada/Greenland Joint Commission on Conservation and Management of Narwhal and Beluga Witting reported that there have been no meetings of the Canada/Greenland Joint Commission on Conservation and Management of Narwhal and Beluga (JCNB) in 2006 and 2007. Presently no meetings are planned. Chairpersons of the NAMMCO/JCNB Joint Working group are Rod Hobbs for NAMMCO and Steve Ferguson for JCNB.

6. ROLE OF MARINE MAMMALS IN THE MARINE ECOSYSTEM

6.1 Update on the upcoming Dartmouth conference (September/October 2008) Haug informed the Committee about the symposium on “The Role of Marine Mammals in the Ecosystem in the 21st Century” which will take place in Dartmouth, Canada, 29 September – 1 October 2008. This symposium will revisit the issues that formed the base for the 1995 symposium by the same name and chart progress in this field. Furthermore he mentioned that the ICES Annual Science Conference which will take place in Halifax, Canada, immediately before the above mentioned symposium,

Report of the Scientific Committee noting that the session “The role of sea ice in polar ecosystems” could have particular interest for the Delegates (see 5.3). Stenson (NAFO) and Haug (ICES) act as co-conveners while Hammill, Hammond, Thompson are the members of the Scientific Steering Committee. Víkingsson was appointed as special NAMMCO liaison officer.

There will be four conference sessions: 1) “Biological and environmental factors affecting life history traits” with key note speaker Mark Hindell (University of Tasmania, Tasmania, Australia) 2) “Foraging strategies and energetic requirements” key note speaker Dan Costa (University of California Santa Cruz, California, USA) 3) “Theoretical considerations on apex predators and multi-species models” key note speakers Andrew Trites (University of British Columbia, British Columbia, Canada) 4) “Marine Mammals and Fisheries interactions” key note speaker John Harwood (University of St. Andrews, Scotland, United Kingdom).

The proceedings of the symposium will be published in the NAFO publication “Journal of North West Atlantic Fisheries Sciences”. Funding from NAMMCO amounts to 20,000 NOK, which will be transferred to NAFO for reception and speaker costs. Víkingsson agreed to report about this symposium to the next SC meeting. The Chair recommended to the scientist from NAMMCO countries to submit their work to this event.

6.2 Update on progress on modelling Lockyer referred to the report by Gunnar Stefansson as NAMMCO observer to the workshop on Ecosystem Approach to Fisheries (EAF) coordinated by FAO and held 2-6 July 2007 in Tivoli, Italy. The purpose of this workshop was to define “best practice” standards for developing, testing and applying ecosystem models in relation to an EAF. A direct benefit of an EAF relies on the possibility of addressing issues, which were impossible to be dealt with using a single-species approach.

Participants in the workshop included modelling experts from all continents, with expertise in a variety of modelling approaches applied to ecosystems in all major regions of the world.

The overall goal of an EAF as defined by Garcia et al (2003):

“…. strives to balance diverse societal objectives, by taking account of the knowledge and uncertainties of biotic, abiotic and human components of ecosystems and their interactions and applying an integrated approach to fisheries within ecologically meaningful boundaries”,

120

NAMMCO Annual Report 2007 - 2008 has led to a growing awareness and recognition of the need for fisheries management to consider the broader impact of fisheries on the ecosystem as a whole and the impact of the ecosystem, and other users of the ecosystem, on fisheries. The recognition of broader economic and social interests under an EAF implies that the setting of management objectives will need a broader consideration of ecological values and constraints than is currently the case. This will require a broader stakeholder base, increased participation and improved linkages of fisheries management with coastal/ocean planning and integrated costal zone management activities. It follows that there is an immediate need to take a look at current models and modelling frameworks and see how these fit into an EAF. The term “ecosystem models” has traditionally been used quite broadly and these can potentially range from simple analyses of species interactions (regressions) through minimally realistic models describing a few species to models which describe tens of interacting species, multiple fleets and anthropogenic effects such as pollutants.

The work of Plaganyi (2007) which extensively reviewed existing multispecies and ecosystem modelling work formed a good basis for the workshop. One conclusion from that paper was that the Gadget framework is promising for Minimally Realistic Models (MRM), i.e. models that attempt to capture the essence of species interactions of interest without becoming overwhelmingly large or all encompassing. On the other hand, it was noted that larger ecosystem models such as EwE or Atlantis are good candidates for understanding structure, exploratory analyses and have potential as an operating model (OM) for an MSE evaluation (Fulton et al. 2005). It is, however, quite clear that these all-encompassing models cannot be evaluated using the MSE approach because they include too many parameters which have to be assumed and are at present far too unwieldy to be evaluated as a part of a large simulation exercise.

The currently considered models/approaches vary widely and it follows that standards need to be set so that management can rely on best practice having been followed when models are going to be used in an EAF. The workshop defined a large number of issues or model attributes and specified which protocols should be applied during model development, starting from a conceptual model up through evaluating and testing the model. It was also considered best practice to include a variety of error assumptions in these evaluations. Many of these issues need to be addressed before any computer programmes are written or formulae are put on paper. NAMMCO should carefully consider these definitions of best practice to evaluate which can reasonably be implemented in ecosystem model work planned by NAMMCO.

6.3 Working Group on Marine Mammal-Fisheries Interactions Desportes reported that Walløe, who is chairman of this WG, had shortly corresponded with the Secretariat before the meeting. He had been to a meeting in Japan in connection with IWC work and that he noticed that Japanese scientists are using ECOPATH for modelling. He commented that the new developments in Japan and Norway justified the revival of the Working Group on Ecosystem Approach and he suggested holding a meeting in the early part of the next year or back to back with the SC meeting. Walløe is willing to chair the meeting if the SC so wishes.

Report of the Scientific Committee

Víkingsson reported on the Icelandic plan to hire a modelling specialist to work on their energetics and ecosystem data. He mentioned that regrettably progress is very slow not only because of delays in the headhunting process, but also because of delays in gathering the necessary data. The time frame for employment of the expert ideally aims at hiring a modeller before a Working Group meeting which could take place in the early spring 2009.

The Committee recommends the revival of the Working Group, as there are sufficient new developments in the field to justify such an action. In light of the new survey results, the SC recommends that the WG to expand its terms of reference to include all areas under NAMMCO jurisdiction and investigate dynamic changes in spatial distribution due to ecosystem changes and functional responses (ref. to T-NASS item). Gunnar Stefansson would be a good contributor to this meeting as well as Japanese ecosystem modellers.

6.4 Icelandic programme on the feeding ecology of minke whales Iceland presented some preliminary results to the NAMMCO Council meeting in 2006. Since then, new material has become available from the sampling undertaken in 2006 and 2007. From a study based on limited sampling during 1977-1997 the diet consisted mainly of krill, sand-eel and capelin. Preliminary findings from the present study show much less proportions of krill and capelin and more sand-eel and large bony fishes (cod and other gadoids). On a rough scale (% frequency as dominant species), about one quarter of the diet is composed of large bony fishes, mainly cod and haddock. This is much more than the model presented to the ICES, which assumes that cod represents 3% of the diet. It seems that the diet used in the original model developed by Stefansson (2003) has changed significantly. While sand-eel is still a major component of the diet, its importance decreased over the study period. This is in accordance with other studies showing a decrease in sand-eel abundance in Icelandic waters and decrease in breeding success of seabirds typically feeding on sand-eels in recent years. Results from this research are expected to be presented to the next SC meeting as well as at the next meeting of the Working Group on Marine Mammal Fishery Interactions and the ICES/NAFO/NAMMCO symposium (see 6.1 and 6.3).

6.5 New request and future work Regarding the new request of reviewing the results of the Icelandic programme on the feeding ecology of minke whales and multi-species modelling as soon as these become available, the Committee recommended a revival of the Working Group on Marine Mammals and Fisheries Interactions (see 6.3). Besides reviewing progress on multi-species modelling, this group would review the Icelandic Programme on feeding ecology of minke whales. The Committee recommended that this group hold a meeting before March 2009 and after the Dartmouth Symposium.

6.6 Other matters Both Norway and Russia have expressed concerns over the current size of the Northeast Atlantic harp seal populations and their predation on fish stocks, in particular in the Barents Sea. To be able to assess the ecological role of harp seals by estimation of the relative contribution of various prey items to their total food 122

NAMMCO Annual Report 2007 - 2008 consumption, a Joint Norwegian-Russian Research Programme on Harp Seal Ecology has been initiated. The focus of this programme will be to: • assess the spatial distribution of harp seals throughout the year (experiments with satellite-based tags) • assess and quantify overlap between harp seals and potential prey organisms (ecosystem surveys) • identify relative composition of harp seal diets in areas and periods of particular intensive feeding (seal diet studies in selected areas) • secure the availability of data necessary for abundance estimation • estimate the total consumption by harp seals in the Barents Sea (modelling) • implement harp seal predation in assessment models for other relevant resources (modelling).

The programme was adopted by the Joint Norwegian-Russian Fisheries Commission and supported by the NAMMCO SC in 2006. However, although both ecosystem surveys and abundance estimation of harp seals are in progress, the core activities of the programme have not yet been properly started, the reason being that Russian authorities refused to permit deployment of satellite tags on harp seals in the White Sea in May, both in 2007 and 2008.

To ensure that tagging will take place in 2009, Norway and Russia have agreed to organize a research cruise in late May / early June in 2009, to deploy satellite tags on harp seals on ice in the area southeast of . The cruise will be part of the joint harp seal programme, involving both Norwegian and Russian scientists. However, tagging seals in the White Sea is still the most preferable approach, as it ensures that only seals from the White Sea stock are tagged, and because tagging of different sex and age groups can easily be balanced. Therefore, the Russian part will apply for permission to tag seals in the White Sea also in 2009. The Norwegian part will provide all necessary technical information about the tags and the operation, if necessary modifying the equipment used. It is the Federal Technical Committee (FTC) that has forbidden all satellite tagging in Russian waters.

The NAMMCO SC strongly regrets the decision made by the Russian FTC and recommends that Russia permits Norwegian and Russian scientists to conduct this important tagging experiment with harp seals in the White and Barents seas according to the original plans.

7. SEALS AND WALRUSES STOCKS - STATUS AND ADVICE TO THE COUNCIL

7.1 Harp seals and 7.2 Hooded seals 7.1.1 and 7.2.1 Update on progress The 2007 aerial surveys in the Greenland Sea Harp seal pup production was assessed in the Greenland Sea in 2002 (Haug et al. 2006), hooded seals in 2005 (Salberg et al. 2008). Preferably, abundance estimates of hunted seal stocks should be obtained no less than every 5 years, and surveys and 123

Report of the Scientific Committee associated data that are more than 8 years old are too old to be considered recent. Therefore, the plan was to conduct new surveys to obtain data necessary for estimation of the abundance of harp seals of the Greenland Sea stock in 2007. However, the low pup production estimate obtained for hooded seals in the area in the 2005 survey caused so serious concerns that ICES and NAMMCO had advised Norway to stop the hooded seal catch from 2007 on, and recommended that a new hooded seal survey be carried out already in 2007. Besides revisiting all areas historically used by hooded seals for breeding purposes in the Greenland Sea, new areas to the north and south of these areas were covered with reconnaissance flights during the survey. In addition to the abundance estimation using aerial surveys, also a number of animals of various ages were killed for scientific biological sampling to obtain updated information on reproductive rates and health status of hooded seals.

If possible, a secondary goal was also to obtain a new abundance estimate for harp seals in the area during the same survey. Evidently, given the available logistical resources and the priority of hooded seals, obtaining a harp seal pup production estimate would require that harp seal breeding occurred within the same main areas as the hooded seal breeding. During the survey, it proved possible to obtain data on the pup production of both harp and hooded seals in the Greenland Sea in 2007.

The aerial surveys were performed in the period 14 March to 3 April 2007 (Haug et al. 2007). Two fixed-wing twin-engine aircrafts, stationed in Constable Pynt (East- Greenland), Akureyri (Iceland), and the Jan Mayen island, were used for reconnaissance flights and photographic surveys along transects over the whelping areas. A helicopter, operated from the applied expedition vessel (M/V “Nordsyssel”) also flew reconnaissance flights, and was subsequently used for other purposes, such as monitoring the distribution of seal patches and age-staging of the pups.

The reconnaissance surveys were flown by the helicopter (14 – 24 March) and the fixed-wing aircrafts (21 March – 3 April) in an area along the eastern ice edge between 66° 55’and 75° 30’N. Obviously, the ice cover was narrow and the edge close to the Greenland coast in 2007, and all surveyed areas were overlaying the continental shelf (300 - 400 m depth). The reconnaissance surveys were adapted to the actual ice configuration, usually flown at altitudes ranging from 160 - 300 m. Repeated systematic east-west transects spacing 10 nm (sometimes 5 nm apart) were flown from the eastern ice edge and usually 20-30 nautical miles (sometimes longer) over the drift ice to the west. The reconnaissance surveys detected no apparent hooded seal whelping concentrations, only scattered hooded seal families and, subsequently, solitary bluebacks over a relatively large area ranging from 72º 00’N and 73º 51’N. Scattered harp seal whelping was observed in the same area, whereas a more concentrated harp seal whelping patch was observed to the east of the scattered hooded seals between 73º 00’N and 73º 40’N.

One aircraft was equipped with a Leica RC 30 camera with a motion compensation mechanism shooting AGFA Pan 400 black-and-white film. The second aircraft was fitted with a Vexcel Ultra Cam D digital camera, which provided multi-channel images (Red Green Blue Infrared). 124

NAMMCO Annual Report 2007 - 2008

On 27 March, a total of 19 photo transects, spacing 5 nautical miles, were flown using both aircrafts in the area between 72º 00’N / 18º 35’ - 16º 49’ W and 73º 30’N / 15º 40’ - 13º W. The survey covered the entire area of scattered whelping hooded seals, including also scattered whelping harp seals in the northern parts of the covered area. The survey was conducted with low-density photographic effort where two photos were shot per 1 nm along each line, resulting in a total of 1,136 photos.

On 29 March, the area between 73º 03’N / 15º 42’ - 14º 42’ W and 73º 33’N / 15º 20’ - 13º 50’ W was covered using both aircrafts simultaneously in a high-density coverage of the concentrated patch of whelping harp seals. A total of 16 photo transects, spacing 2 nm, were flown with cameras operated to ensure about 80-90 % coverage of the area along each transect line, resulting in a total of 1987 photos shot.

A second, smaller harp seal whelping concentration was covered in another high- density coverage on 3 April in the area between 71º 22’N / 17º 40’ - 18º W and 71º 30’N / 17º 27’ - 17º 46’ W. Five photo transects, spacing 2 nm, were run with 80-90 % coverage of the area along each transect line, resulting in a total of 264 photos shot.

Only very few whelping hooded and harp seals were observed outside the surveyed whelping areas. The results from the aerial surveys will be used to estimate the 2007 hooded and harp seal pup production in the West Ice. Subsequently, the status of the stocks will be assessed by fitting population models to the pup production estimates.

In previous hooded seal surveys, the surveyed areas have traditionally consisted of two strata types: (1) whelping concentrations where both visual and photographic surveys were conducted with high-density coverage, and (2) scattered pups outside the whelping concentrations, which were covered with low-density photographic surveys only. In 2005, Greenland Sea survey hooded seal whelping occurred in three well- defined concentrations, but it was not possible to run an additional low-density coverage survey of scattered pups outside these whelping concentrations. Owing to this, the total estimate presented is slightly negatively biased. In 2007, all pupping of hooded seals occurred scattered with no major patches of concentrated breeding. This will increase the uncertainty in the estimate obtained – it remains to see how the new estimate compares with the 2005 estimate.

Reconnaissance of possible new harp and hooded seal breeding patches in the Greenland Sea In southwest Greenland in April 2007, a concentration of at least 1,000 white coat harp seal pups arrived with the drift ice from East Greenland. These seals must have been born close to the tip of Greenland. This is the first time such an event has been observed.

A reduction in extent and concentration of drift ice has occurred in the Greenland Sea between Greenland and the Jan Mayen Island. These changes must have resulted in substantial changes in breeding habitat for the Greenland Sea populations of harp and hooded seals. Could these changes in ice-conditions have triggered behavioural changes of such a magnitude as a relocation of breeding for at least parts of the 125

Report of the Scientific Committee populations? Recent low pup production in hooded seals, and new (2007) discoveries of breeding harp seals in areas outside those used historically by the species could both be indicative of such changes. The NAMMCO SC recommends that this is examined further by using aerial surveys to investigate whether a southward relocation of breeding has occurred for parts of the harp and hooded seal populations in the Greenland Sea. If new breeding patches are observed, this will have considerable implications for future research, management and hunting activities in the area.

Abundance estimation of harp seals of the Barents Sea / White Sea population In a historical assessment of the Barents Sea / White Sea population of harp seals, Skaug et al. (2007) suggested that this population might have numbered as much as 6 million animals in 1875. The estimate was obtained by fitting a population dynamics model to all available (up to 2003) sources of data, but because of a lack of information about several key parameters in the model, the uncertainty associated with the estimate is large. A sensitivity study involving three different mechanisms for density-dependence results in a range estimate of 3-7 million seals in 1875.

Russian aeroplane surveys of White Sea harp seal pups were conducted in March 2004 and 2005 using traditional strip transect methodology and multiple sensors. The results obtained may indicate a reduction in pup production as compared with the results obtained in similar surveys in 1998-2003. Surveys flown with helicopters in March 2006 and fixed-wing aircraft in March 2007 apparently confirm the possible reductions in pup production. Severe reductions in both period and extension of ice cover in the White Sea in recent years may have contributed to the possible reductions in pup production in the area. Zabavnikov informed that new aerial surveys had been conducted in the area in 2008 to investigate whether this possible reduction in pup production still prevailed. In addition, any possible relocation of breeding were assessed by reconnaissance flights to areas both in the White Sea and in the south- eastern Barents Sea (e.g., around the Kolgujev island, in the ). No breeding was observed outside the White Sea, and the ice conditions in the White Sea seemed somewhat more favourable for harp seal breeding in 2008 than in 2004-2007. Aerial photographs taken of the breeding patches in the White Sea are now being analysed. Incidentally, walruses with pups were observed during the surveys in the Pechora Sea. The first results of harp seal White Sea – Barents Sea pup productions from aerial surveys for 2008 will be presented in the joint ICES-NAFO WG in August 2008 in Tromsø.

Monitoring of biological parameters in harp and hooded seals Selected life history parameters are used in models designed to convert pup production into population size. Data used to estimate these parameters must be updated at regular time intervals (5-8 years) for all exploited populations. In the Greenland Sea in 2008, hooded seal biological samples to assess life history parameters will be obtained from seals sampled for scientific purposes in a dedicated research cruise in June/July, if possible also from local Greenland hunters. Sampling from harp seals will be collected from the commercial Norwegian hunt in the Greenland Sea. Russian scientists will collect material from the Russian hunt on one vessel operating in the White Sea and during coastal research activities (using land-based inflatable boats) on the Murman 126

NAMMCO Annual Report 2007 - 2008 coast. Norwegian and Russian scientists will coordinate both sampling and subsequent analyses of the collected material.

7.1.2 Future work In 2005, the Council requested an evaluation on how a projected decrease in the total population of Northwest Atlantic harp seals might affect the population of animals summering in Greenland. The Committee responded that: • The abundance of Northwest Atlantic harp seals may be stabilizing after a period of rapid increase (2004 survey). • The numbers summering off West Greenland would also be expected to stabilize. • However, the proportion of animals migrating to Greenland may not be constant and may change in response to environmental conditions. • The age structure of the population will change as it stabilizes, and this may also affect the numbers summering in Greenland. • Detailed information on harp seal migratory patterns are required to assess this.

The Committee recommended in 2005 that: • ICES-NAFO Working Group be asked to address this request and recommended that Greenland forward this request to ICES. • If that was not possible, to organize a special working group, with active participation by Canada, to address this issue.

The Committee reiterates its recommendation that the ICES-NAFO Working Group be asked to address this request, as a first step. The Committee urges Greenland to forward this request to the ICES-NAFO Working Group on Hooded and Harp seals as soon as possible, so this matter could be dealt with at the next meeting in late August 2008.

The Committee recommends flying reconnaissance surveys (e.g. south of 67°N in East Greenland) to investigate the possible presence of whelping patches in “non- traditional” areas, to continue the sampling for biological parameters, and the characterization of stock identity.

7.2 Hooded seals Lydersen reported on the International Polar Year programme “Marine Mammals Exploring the Oceans Pole to Pole (MEOP)”. In this programme, animals that exhibit spectacular movements and diving behaviour are equipped with oceanographic data recording satellite tags (Sea Mammal Research Unit -SMRU tags) with the intention of gathering physical data on zones of difficult access at a minimal cost. Within this framework, in the July 2007 three hooded seals captured on the ice after moulting were equipped with such tags and released. These animals performed extensive travel across the whole North Atlantic relaying excellent oceanographic data on temperature and salinity. With the intention to repeat and improve the previous year’s success a new attempt was made in March 2008. On this occasion, 17 tags were set out in only

127

Report of the Scientific Committee four days’ work. These tags are expected to have a more limited operational life than the previous ones as they will be shed during moulting. However, the instrumented bluebacks are expected to carry the instruments for 16 months after attachment. Preliminary information indicates that the animals tagged in 2008 follow the same movement patterns as those instrumented in 2007.

Seven adult hooded seals were also tagged off southeast Greenland in 2007. Like previously tagged adult hooded seals, these seals went to feeding grounds in Davis Strait/Baffin Bay and from there down to the whelping ground off the Labrador/Newfoundland coast where they are at present (April 2008).

7.2.1 Update on progress See above.

7.2.2 Review of SC recommendation from 2006 The Committee recommended in 2006 that catches in the Greenland Sea be restricted to necessary scientific catches and to satisfy local needs at roughly current levels. This should be accompanied by a monitoring programme. This recommendation was to be revisited after the results from the 2007 survey became available. These results were not yet available, and it was noted, however, that no whelping concentrations were detected but only scattered whelping. This latter would increase the uncertainty of the pup production estimate. The question of possible alternative whelping patches (see under 7.1.2) was also crucial.

7.2.2 New Requests and future work Council requested that the SC investigate possible reasons for the apparent decline of Greenland Sea stock of hooded seals and assess the status of the stock on the basis of the results from the planned survey in 2007. This request has already been forwarded to the ICES-NAFO WG, which meets in Tromsø in August 2008.

7.3 Ringed seal 7.3.1 Update on progress Very little is known about this species. Lydersen presented some progress made on behaviour.

Tryland et al (2006), reported that the GPS positions of ringed seals shot by hunters have been related to sex and body size. It appears that older male seals have a larger and better territory and access to a higher number of females.

Studies on ringed seal tagging and genetics in Alaska showed that this species exhibits a high site fidelity and that both sexes return to the same area on consecutive years (unpublished interim project report by Brendan Kelly, 2008 – Lydersen pers.comm.).

The separation though is not universal as demonstrated by a study on animals from Svalbard (Freitas et al, 2008) where some individuals are stationary, by the glacier front throughout the year while others migrate to and from the area according to the

128

NAMMCO Annual Report 2007 - 2008 season. This behaviour could indicate a reaction to the reduction in habitat due to climatic changes that forces the surplus seals to perform seasonal migrations.

The spatial distribution of various age- and sex groups of ringed seals (N = 94; 19 adult males, 33 adult females and 42 sub-adults) was studied in their fast-ice breeding habitat in Kongsfjorden, Svalbard, during May 2004 by Krafft et al (2007). Adult females occupied the inner, most stable ice area, while sub-adults were found predominantly in the outer parts of the fast-ice where the ice conditions are more unstable. Adult males were scattered across these two areas; some were intermingled with breeding females while others were found further out towards the ice edge in areas mainly dominated by sub-adults. This pattern suggests territorial behaviour with competitive exclusion of the sub-adults and adult males that cannot compete for territories in the prime breeding areas. The size of adult males was correlated with their testosterone levels, but it was not necessarily the largest males that had the most adult female neighbours. The adult males that had the most adult female neighbours were however significantly older than the adult males with fewer female neighbours (18 ± 1 vs 12 ± 1 years). This suggests that experience (age) likely plays a strong role in achieving reproductive success for male ringed seals. A male:female sex ratio of 1:2.4 was found in the prime breeding area, which suggests a slightly polygynous mating system.

Freitas et al (2008) noted that intra-specific and intra-population variation in movement tactics have been observed in many species, sometimes in association with alternative foraging techniques or large-scale habitat selection. However, whether animals adjust their small-scale habitat selection according to their large-scale tactics has rarely been studied. This study identified two large-scale movement tactics in ringed seals (Phoca hispida) during their non-breeding, post-moulting period. First- passage times (FPT) were used to explore these large-scale patterns. Subsequently, habitat selection was quantified by modelling the FPTs as a function of habitat attributes using Cox proportional hazards models. Some seals moved far offshore into areas preferentially containing 40-80% ice coverage, while other individuals spread along the coasts of Svalbard concentrating their time near glacier fronts. Both tactics resulted in ringed seals being in highly productive areas where they had access to ice- platforms to rest. When offshore, habitat selection was influenced mainly by sea ice concentration and season. Late in the season (autumn), increased risk of leaving an area was identified, even when ice conditions were still favourable, reflecting their need to return to over-wintering/breeding areas before the fjords of the archipelago freeze. For ringed seals that remained inshore, habitat use intensities were influenced mainly by the distance to glacier fronts and season. These animals were already close to their over-wintering habitat and hence their risk of leaving an area decreased as winter approached. This study of ringed seals habitat selection reveals how they fulfil their biological requirements in this dynamic, heterogeneous habitat. Individuals within the same population employed two distinct large-scale movement tactics, adjusting their decisions for small-scale habitat selection accordingly. This flexibility in ringed seal spatial ecology during summer and fall is expected to result in increased population viability in this high arctic environment.

Report of the Scientific Committee

7.3.2 Future work A new kind of tag attached to the hind flippers has given promising results in Alaska, and will in the future make it easier to study movements of this seal species.

The Committee reiterates its recommendation for initiating studies on ringed seals on sea ice in offshore areas, and for addressing importance of pack-ice breeding, especially in the present context of climatic changes and subsequent changes in ice condition and cover.

7.4 Grey seal 7.4.1 Update on the Norwegian 2006 and 2007 surveys and effect of harvest levels Grey seal abundance estimates along the Norwegian coast were obtained in 1996-1998 and in 2001-2003 (Nilssen and Haug 2007). Haug reported that a new estimate, based on field work carried out in 2006-2008, will be available by the end of this year. Norway and Russia has agreed that the Russian grey seal breeding colonies at the Murman Coast should be covered during the same period. Zabavnikov informed the NAMMCO SC that this would be done, presumably using helicopter, in November- December 2008. Zabavnikov further reported that the last Russian survey was carried out in 1994. This species is not hunted in Russia and apparently there is no by-catch.

A major genetic study covering all North Atlantic areas, has been initiated by Norway. Haug presented SC/15/21 that reported some preliminary results from analyses of mitochondrial control region sequences. No overlap was found in haplotype distributions between samples from the three main distribution areas in Canada, the Northeast Atlantic, and the Baltic Sea. Within the Northeast Atlantic, analyses of molecular variance (AMOVA) identified 5 main subdivisions consisting of 1) Iceland, 2) Scotland and southern Norway, 3) Central Norway, 4) Northern Norway, and 5) North-eastern Norway and Russia. Based on exact tests of haplotype frequency distributions, all sampling localities were significantly differentiated from one another. The latter results are consistent with data on dispersal distance derived from conventional tagging experiments in Norway and suggest that two or more demographically independent units are likely to be present within the current Norwegian grey seal management units.

Quotas in previous years have been set to 25% of the population estimate. The removals have however, been at the scientifically recommended level (5% of abundance). A management plan for coastal seals in Norway is in progress and is due for completion this autumn. At that time it will probably be submitted for endorsement to the NAMMCO Scientific Committee.

The SC reiterates its recommendation on the quota level in Norway, estimated non- sustainable, but commended that the management plan was on its way and recommended that it should be presented to NAMMCO for evaluation.

7.4.2 Update on the Faroese satellite tagging programme and catch levels

130

NAMMCO Annual Report 2007 - 2008

Mikkelsen explained that knowledge of breeding of these seals in the Faroes is absent. There are very few catches and mostly as defensive measures in relation to fish farms. Effort is being planned to locate breeding areas, which in the Faroes are situated in caves. Four satellite tags have been deployed on juvenile seals in June 2007 and one of the tags transmitted until February 2008. In 2008 six tags are planned to be deployed preferably on adult females.

The SC commended the effort made by the Faroes to obtain better information on the population of grey seals (by means of satellite tagging) but reiterates its recommendation that immediate effort be made to obtain better information on the nature and impact on the take in the Faroes, and to obtain information on breeding sites.

7.4.3. Update on other progress There is no new information available about Icelandic grey seals. The last survey on grey seals was in 2005, and a new survey is planned in 2008. Routine age monitoring of 112 grey seals (and one harbour seal) was performed in 2006. The management advice provided is similar to the previous years as there are no indications of change in the population.

The Committee recommends Iceland to provide new data on age composition of the catch.

7.4.4 Future work Zabavnikov mentioned that the Russian Federation has plans to initiate aerial survey activities for grey seals.

The SC considered that it was timely to hold a Working Group meeting on grey seals in 2009. By that time there will be new Icelandic and Norwegian abundance estimates. This will coincide with the endorsement of the Norwegian management plan.

7.5 Harbour seal 7.5.1 Update on progress 7.5.1.1 Greenland: update on the recommended research programme There are advanced plans to monitor both size and distribution of the population in South Greenland. The cameras necessary for monitoring the haul-outs were not ready by September 2007 but will be installed in June 2008 when there will also be an aerial survey for haul-out sites conducted.

Interestingly, even if it was thought that harbour seals had left central Greenland, a small population has been found upstream in some rivers that flow from the inland ice by Maniitsoq. This phenomenon will be further investigated in future years.

The area on the far south of Greenland interests oil companies. The Greenland Institute of Natural Resources (GINR) and the Danish National Environmental Research Institute (NERI) have submitted common proposals for baseline investigations in the area. 131

Report of the Scientific Committee

Most of the reported Greenlandic catches of harbour seal during 1993-2005 included reporting errors, with statistics reporting catches of up to 700-800 per year. After a new, improved reporting system was put in place, the catches have been stable at a more realistic level under 100 per year.

The SC complimented Greenland for having started the implementation of the Research Programme recommended by the SC in 2006 in such timely manner. However, the SC reiterates its conclusion on the need for enforcement of a total ban on hunting for this species.

7.5.1.2 Icelandic historical catch series and by-catch monitoring programme Ólafsdóttir reported that a survey in 2006 estimated the population at 12,000 individuals. This level seems to match the figure from the 2003 survey. In the later years Icelandic catches have declined, but insufficient information on by-catch is available. This prevents an estimate of total removals and therefore the design of an adequate management plan. The advice provided to the Icelandic government by the Institute of Marine Research (IMR) is to implement a management plan for this species.

The Committee reiterates its recommendation for a formal assessment of the stock and the establishment of clear management objectives. It also renews its recommendation from the last meeting about collecting information on the by-catch.

7.5.1.3 Norwegian by-catch monitoring Haug communicated that there are no new abundance estimates for Norwegian harbour seals yet available. The last population estimate dates back to the period 2003- 2006. By-catch which will be discussed later, will be included in the reported takes in the new management plan which is under development.

He also pointed out that the data from surveys are minimum counts. Correction factors are under development by means of ground truthing studies. These are running side- by-side with habitat use studies involving the use of GSM transmitters.

Genetic relationships in this species are investigated based on samples gathered from Greenland (21), Iceland (34) northern Norway (59) and Svalbard (60). Preliminary results clearly define 4 separate populations and indicate that Greenland and Svalbard seals are more closely related to each other than to Northern Norway or Iceland. This characterization reflects possible migration routes from Iceland and Svalbard to Greenland.

The Norwegian Polar Institute has received support from the Norwegian Research Council to perform harbour seal aerial surveys in Svalbard, satellite tracking and investigations of predation on harbour seals by Greenland Shark.

7.5.2 New request and future work The Scientific Committee was requested to provide a formal assessment of the status of harbour seals around Norway and Iceland as soon as feasible. 132

NAMMCO Annual Report 2007 - 2008

In Iceland, new abundance estimates are available, but there is still insufficient information on by-catch.

Norway implemented a system for assessment of the two coastal seal species that secures updated information about abundance approximately every 5 yr. This system has provided two abundance estimates after 1996. As a third point estimate is needed for an assessment for harbour seals another survey is needed and will probably be performed by 2010.

The Committee considers that an assessment of the species should await until a third abundance estimate is available from Norway and until new, reliable by-catch data, new information on multipliers (ground truthing), and the distribution of catch areas are secured. It is reasonable to imagine that the Norwegian management plan will be ready by 2010. A similar timeframe will also be required for Iceland to develop its own programme. The SC recommends that both countries ensure better information on by-catch and on the proportion of direct catch and by-catch and their age composition and that an assessment be conducted in 2010.

7.6 Walrus The Scientific Committee was asked to provide advice on the effects of human disturbance, including fishing and shipping activities, in particular scallop fishing, on the distribution, behaviour and conservation status of walrus in West Greenland. There has been no progress made on this issue.

7.6.1 Update on results from the 2006 (by GINR and NERI) and 2007 surveys A new abundance estimate for West Greenland walrus was obtained in 2006. The results were not presented at the meeting but gave an estimate, corrected for potentially submerged animals during the survey, of 3,085 animals (90% CI: 1,239- 7,681). Minimum counts of walruses hauled out on South East Baffin Island, were made during the same period and resulted in at least 775 animals. A correction for animals potentially at sea during the counts increases this estimate to at least 2,600 walruses for South East Baffin Island.

Satellite transmitters were attached to walruses in Central West Greenland in March 2006. They transmitted for more than a month during which two animals moved towards the coast of South East Baffin Island. Another one moved from Store Hellefiskebanke to the bank west of Disko Island. The others remained in the area where they had been tagged. In August 2007 during ground surveys in South East Baffin Island an animal was observed at a haul out with a satellite transmitter that had been deployed in Central West Greenland. These data confirm the hypothesis of a common stock of walrus between Greenland and Canada.

Aerial surveys are planned for 2009 in the North Water area.

The surveys planned for 2007 and 2008 in Greenland have been cancelled. In 2009, aerial survey are planned in East Greenland and the North Water area, as well as satellite tagging in the North Water area. 133

Report of the Scientific Committee

7.6.2 Update on the Greenlandic catch series No progress has been made on the old catch series, which accounts for takes up to 2006. The Committee reiterates its recommendation that this be done, since it is required for a reliable assessment. A new, friendlier system for reporting catches similar to the one in force for narwhals and polar bears is effective since 2006-2007.

7.6.3 Update on the 4-year Greenlandic research programme Information is given under 7.6.1

7.6.4 New request and future work The Council requested the Scientific Committee to provide a formal assessment of the Davis Strait stock as soon as finalization of the catch series is complete and the results from the planned 2007 survey are available.

The Scientific Committee is then requested to provide estimates of sustainable yields of the North Water and West Greenland stocks of walrus. Considering the new data upcoming from the work conducted in 2006-2008, and the plan for 2009, the Committee recommends using this new information as input to a Working Group for the assessment of walrus. An assessment meeting for the West and North Greenland stocks should be held as soon as possible in 2008. A similar meeting for the East Greenland stock should subsequently be held. The Committee reiterates, however, the need for updating/revising the old catch series (see under 7.6.2).

Russia: Zabavnikov informed about the intention of the Russian Federation to carry out walrus aerial surveys close to the Gasprom exploitation area by Dolgy Island. Multi-spectral surveys are planned for 2008-2009.

Norway: Lydersen communicated that the walrus surveys in Svalbard 2006 were accepted for publication in 2007. The numbers are 2,629 (95% CI: 2,318-2,998).

New information on the historical sex ratio, is reported in an article by Wiig et al (2007). Presently the Svalbard walrus population is composed almost exclusively of males while in the 19th century it comprised 70% males. Most females are now in the Franz Josef land area while the males are in Svalbard.

On Svalbard, three automatic cameras have been set up to investigate the influence of tourism at walrus haul-outs and in 2008 an additional two should be installed. This project is designed to provide data on trends, to indicate potential effects of disturbance. This study will contribute in answering the request from the Council on providing advice on the potential effects of human disturbance on walruses.

8. TRANS NORTH ATLANTIC SIGHTINGS SURVEY

8.1 Reports of the Working Group for T-NASS

134

NAMMCO Annual Report 2007 - 2008

Third T-NASS planning meeting: St. Andrews, March 30 – April 1, 2007 (see NAMMCO/17/5 Annex 1.1) Canada, the Faroes, Greenland, Iceland, Norway and Russia participated, as well as representatives from the SCANSII/CODA project and the IWC. The full report of the meeting is included as Annex 1.1.

Chairperson Geneviève Desportes reminded participants of the unprecedented uniqueness, value and synoptic character of T-NASS. She reminded the delegates that they had agreed on a strong coordination. The list of agreements from the two previous meetings and a remainder of time constraints ahead followed.

A status of the project was made. The resources per area as well as the secured funding were presented by the different parties. The external funding obtained as well as other possible sources of funding were discussed.

Coordination with opportunistic surveys The three surveys contacted had agreed to have T-NASS dedicated whale observers onboard. The German and the Russian vessels participating in the Redfish survey in the Irminger sea will each have two observers on board and had agreed to tow hydrophones if provided. NAMMCO would provide three of these observers and PINRO one. The two Norwegian vessels participating in the Pelagic survey in the Norwegian sea would also each have two observers that the IMR would provide. The MAR-ECO vessel could only house one whale observer, provided by NAMMCO, and would tow a hydrophone. All equipment and procedural guides would be provided by NAMMCO.

General strategy for coverage considering both dedicated and opportunistic surveys The value of simple distribution data and the importance of maximizing coverage was generally agreed upon. The opportunistic surveys could likely not be included for a density estimate within IWC framework. In conclusion, it was agreed that all the important areas for which it was necessary to obtain a reliable population abundance estimate of target species had to be covered by a dedicated survey.

The Scans II shipboard methodologies, both acoustic and visual. D. Gillespie and R. Swift made a “hands on” presentation of these with equipment demonstration.

Survey design • The boundaries of the different survey areas were established, taking into account the wish of a continuous coverage between SNESSA, T-NASS and CODA and their different subcomponents, as well as available effort and species distribution. • A stratification was agreed upon, based mainly on known species distribution. • Effort was then allocated to the strata , based on expected density of target species.

135

Report of the Scientific Committee

• Transect design would be carried out at a later point by D. Pike using the distance software.

The Committee regretted that very little, if any, consideration was given to T-NASS in the Norwegian decision on survey area, with highest priority given to survey the Eastern Barents Sea and not to join with the other components of T-NASS.

It recommended that Norway’s survey join up at 74°N with the Icelandic block up to the ice edge appropriately, and that the transit area from Kirkenes be included. The committee urged Norway to use as much effort as they have available for a direct and contiguous participation in the T-NASS effort.

Survey protocols (survey mode and procedures) for shipboard surveys Survey protocols and procedures were agreed upon, based on the adoption of the BT methodology at the previous planning meeting for the Icelandic/Faroese surveys and a standard line transect methodology for the Greenlandic and opportunistic surveys. This was done for the different component of the shipboard surveys. 1) Dedicated Icelandic and Faroese vessels with double platforms, tracking with big eyes and 7x50 binoculars, and eight observers, two primaries, two trackers a duplicate identifier and a data recorder working at the same time. 2) Dedicated Greenlandic survey with a single platform and 4 observers, 3 working at the same time. 3) Opportunistic surveys with a single platform and two observers (one for the MAR-ECO survey), working at the same time. SMRU would be contracted to prepare the equipment for the BT method on the Icelandic and Faroese vessels, since the equipment would be similar to that they were preparing for the CODA shipboard surveys. It was agreed that CODA and T-NASS would have common survey forms (sightings, effort, etc.).

The equipment for the Greenlandic survey would be prepared by Greenland while the equipment for the opportunistic survey would be prepared by NAMMCO.

Rules for adaptation (i.e. changing the design underway) were adopted. It was agreed that training time on land and at sea has to be taken into consideration in the allocation of effort, as it takes time to get used to the new technology and distance estimation. It was agreed that at least 2 in-harbour days be used for training on equipment setup and use, and at least one sea day must be allocated to training in effort conditions and that training would continue further until satisfactory results be obtained.

It was agreed that transects should be based on the realizable effort plus a general bonus of circa 20% (Iceland and Faroes), where there was no other indication by the local coordinators. A parsimonious design will be used especially in the northern blocks assuming equal coverage in order to allow for flexibility to adapt the track design. This will allow the Icelanders to define the final survey tracks as late as possible in order to integrate the best and latest ice information available. If an area is missed by one vessel, another may step in to cover the tracks missed. In general how the “whale survey” time in the Redfish survey will be used must be defined on site. 136

NAMMCO Annual Report 2007 - 2008

Survey protocols for aerial surveys Survey protocols and procedures were agreed upon, for the different component of the aerial surveys. 1) protocol for dedicated surveys with multiple observers, 1 leader and 1 platform (Canada and SNESSA) and multi-species nature: line transect as used in past surveys. 2) Review of protocol for dedicated surveys with 4 observers and 2 independent platforms (Iceland and Greenland – September survey): cue counting for fin and minke whales, with blow being the cue for fin whales and dive the cue for minke whales. In practice, the data collected will be in a manner to allow either cue counting or line transect analyses as appropriate. Flying at 600 feet was recommended if harbour porpoise was a target species.

Acoustic survey It was unclear at the time of the meeting whether there would be funding for this survey, so there was no discussion on this point. It was agreed that protocol would follow the protocol adopted by SCANS II and CODA.

Contact and coordination during the main survey It was agreed that contact and coordination would be established during the survey between the dedicated vessels. This was necessary to ensure internal coordination and solve technical problems, if any. Coordination was also necessary between the Canadian planes.

Desportes, supported by Donovan, will be the general advisor for protocol or design change for the shipboard survey and Donovan for the aerial survey.

Coordination with IPY-ESSAR International Polar Year - Ecosystem Studies of Sub-arctic. and Arctic Regions (IPY- ESSAR) contact person Ken Drinkwater has and will continue receiving all information circulating internally in TNASS. There was no further information on other activities in IPY-ESSAR.

Strategy for dissemination to the wider public and press The NAMMCO Secretariat has been appointed by the NAMMCO Council to be in charge of creating a website for T-NASS (creating site, producing text, maintaining and updating the site), as a subsection of the NAMMCO web site. The update of the site should be performed at least at the beginning and at the end of the survey and at completion of the analysis. There should be links to the IWC, Canada and Russia, USA, as well as to CODA. Multilingual Press Releases should be made available both at beginning and end of the survey.

Tasks to be completed A list was established and agreed upon.

Data validation and analysis

137

Report of the Scientific Committee

It was agreed that having good rules for the validation and quality insurance of the data was as important as good analysis. It was agreed to define in the near future common data validation criteria (e.g. using e-mail) and suggested to start by examining the CODA protocol as an example. It was common understanding that a uniform analysis strategy was paramount for maintaining the synoptic character of TNASS.

It was agreed that it was important to define uniform data validation criteria and that it should be emphasized to the cruise leaders that they should check the quality of the data as frequently as possible. Data should comply with IWC data availability policy if TNASS (NAMMCO) data have to be accepted for use by the IWC for the implementation of a Revised Management Procedure (RMP). An ad hoc Data Group was established to look into these questions, composed of Desportes, Hammond, Donovan, Gunnlaugsson, Mikkelsen, Øien, Lawson, Simon and the NAMMCO Secretariat.

The Committee took note of the report presented by Desportes, but did not discuss it further, since this now belonged to the past.

First T-NASS Debriefing meetings: telephone meetings, November 12-13, 2007 (see NAMMCO/17/5 Annex 1.2) A shipboard surveys debriefing telephone meeting was planned for November 12, 2007. Similarly, an aerial surveys debriefing meeting was planned for the following day.

On the dates of the meetings, only two of the planned seven shipboard survey reports and one of the five aerial survey reports had been delivered by the participants. These reports were to form the basis for the meeting.

Chairperson Genevieve Desportes expressed her strong disappointment and reminded participants that T-NASS was a coordinated action under the auspices of NAMMCO. The debriefing documents were not only instrumental for the meetings, but also an archive of information essential for analysis and for the preparation of future surveys, and needed both to continue updating the T-NASS website and to provide feedback to the Council and to the IPY umbrella project: ESSAR.

Lacking these basic documents, the Chair decided to only deal with the point in the agenda dealing with the status and planning of the analysis for the shipboard surveys data and to cancel the aerial surveys debriefing meeting. The delegates promised they would deliver cruise reports to the Secretariat by the end of November 2007. The need for a debriefing meeting was to be assessed once all the reports were made available.

Analysis status and planning Iceland, Greenland and Norway reported their intention to give highest priority to the production of new abundance estimates for common minke whales (all countries) and fin whales (Iceland and Norway) to be presented at the T-NASS First Analysis 138

NAMMCO Annual Report 2007 - 2008

Meeting, at the NAMMCO Scientific Committee Meeting in April 2008 and at the IWC Scientific Committee meeting in June 2008. The figures would be used within the IWC Revised Management Procedure (RMP) and, in the case of minke whales, they will be included into the IWC Implementation Review. The Faroe Islands expressed their intention to give highest priority to the production of abundance estimates for pilot whales. In most cases, standard line transect analysis would first be used for the analysis of shipboard data, as in previous NASS surveys. BT analysis would later be considered if data warranted it. Greenland reported they would analyse the minke whale shipboard data, but had only few sightings for other species and it was unlikely they would produce estimates for these.

Working papers for consideration at the IWC SC meeting in Chile (May 2008) had to be submitted by the end of February 2008. The Chair noted that the deadline fell before the planned NAMMCO T-NASS meeting (April 2008) and that this implied that T-NASS data would be submitted to the IWC before being submitted to and reviewed within a NAMMCO forum.

Iceland took responsibility for the production of estimates from both minke and fin whale using Icelandic and Faroese data, while the Faroes would take the lead for Pilot Whale data analysis (incl. T-NASS main and extension).

D.Gillespie (SMRU) had accepted to check the quality and quantity of the T-NASS Acoustic data through random screening to better assess the need and possibility for detailed analysis. The delegates agreed to send a copy of both the acoustics and sightings database to D.Gillespie within the nearest future.

Cooperation with CODA An exchange of cruise reports between CODA and T-NASS had been agreed through email. Also according to the agreement, CODA has sent their Cruise Reports to NAMMCO as well as the minutes of the CODA debriefing meeting. It was noted that CODA expected to receive the T-NASS Cruise Reports and the minutes of the T- NASS debriefing meetings in the nearest future.

The Chair noted that CODA had reiterated their interest in continuing cooperation with T-NASS, especially for the spatial analysis component.

Press release and input to the web site The Secretariat reminded the delegates that for the production of a press release, for input to the NAMMCO-based T-NASS web site, and for the preparation of a poster to be submitted to the ECS annual conference in March 2008, they should provide: 1) The data of the total planned and realised effort (which was missing for Greenland) 2) General maps of the realised effort (which was missing for Greenland, the two Norwegian vessels and two of the Icelandic vessels) 3) Maps of the sightings for at least one species (preferably fin whale).

139

Report of the Scientific Committee

In case the Delegates have problems in producing the maps themselves, they had the option to send the Logger Database to the Secretariat with a deadline by the end of the week (16 November 2007).

Second T-NASS Debriefing Meeting: Copenhagen, April 7, 2008 (see NAMMCO/17/5 Annex 1.3) Chairperson Genevieve Desportes noted that T-NASS had successfully achieved a trans-Atlantic coverage (Figure 1) and pointed out that the aim of this last meeting was to carry out a general evaluation and make recommendations for future similar surveys.

The effort planned and accomplished by the different vessels and planes was summarised (Table 1) and illustrated in Figure 1 (see below). The sightings were summarised in Table 2 (see below).

Shipboard evaluation CODA The survey area included offshore waters of the European Fishing Zone west of the UK, Ireland, France and Spain. Shipboard surveys were carried out during July 2007. Double platform methodolology was used and passive acoustic data were also collected. The visual procedure was similar to the procedure implemented during SCANS II. Some technical problems were encountered with the equipment, although not major ones. One of the platforms happened to be totally inadequate for a tracking procedure.

In July, five ships covered 10,000 km of transects in an area of 967,538 km2. Sightings amounted to just over 1,500 encounters of seventeen species.

SNESSA The shipboard survey was concentrated in the coastal waters in the Gulf of Maine. Primary objectives for the shipboard survey were to: 1) determine the spatial distribution and abundance of cetaceans, sea turtles, and seabirds in the study region, 2) use passive acoustics to record vocalizing cetaceans, and 3) conduct oceanographic sampling (e.g., CTD and bongo casts) to help define the habitat throughout the survey region about three times a day. Two teams visually surveyed for cetaceans and sea turtles using the Buckland- Turnock (BT) procedure.

Compared to CODA/T-NASS BT procedure, SNESSA implemented a setup without communication between the two platforms and thus necessitating simpler equipment. The procedure performed very well, with no technical problems.

About 2,970 km of track lines were surveyed, of which ca 80% in Beaufort Sea State less than or equal to 3. The two cetacean teams identified 14 species/species groups of 140

NAMMCO Annual Report 2007 - 2008 cetaceans, and no turtle species, with ca 900 uniquely identified groups. Despite technical problems and loss of equipment, the passive acoustic high-frequency system operated for 785 km and the mid-frequency system operated for about 2,400 km. In addition there were 42 stations where bongo nets and CTDs were deployed to collect plankton and temperature/salinity data.

T-NASS Norway The two Norwegian dedicated vessels followed the double platform procedure established in 1995 and the survey went smoothly, although the weather prevented coverage of more than 56% of the planned trackline.

T-NASS Greenland The vessel used a standard single platform procedure. There were no major technical problems, but the prevalent bad weather (either fog or wind), combined with the time restriction due to the vessel itself (necessity to make water, assistance to vessel) resulted in a poor coverage of most of the block, with the small northeastern block and the southern block not covered at all.

There were however, severe technical problems with the acoustic equipment, and sounds were recorded for only part of the survey.

T-NASS Faroes-Iceland The four vessels had difficulty implementing the BT methodology decided upon (double platform) with the CODA/T-NASS procedure because of technical problems encountered with the equipment provided, which did not perform as expected. The audio systems and the system for communicating between platforms, which is essential for implementing this procedure, in particular was deficient on all vessels. On some vessels, there were also problems with the video and webcam systems. Tracking with the “big-eyes” provided was considered impossible on three of the vessels, either because the optic was not good enough or because the platform was not stable enough.

The training in the new method which was planned before departure at the beginning of the survey, both for the cruise leaders and the observers, could not be implemented. This was either because the equipment arrived too late (on the day of departure for the vessel departing from Reykjavík) or because of the problems encountered with the vessels as such (two of the three vessels departing from the Faroe Islands had to be replaced) and the fact that the platforms were not ready in due time. This was particularly unfortunate when dealing with a new, quite demanding methodology. Some of the observers had difficulty adjusting to such a different and technical method.

Bad weather prevailed most of July combined with extensive ice coverage. This, together with the delay in departure for two of the vessels and the fact that the original effort had been planned too optimistically for some of the vessels, resulted in a low coverage of some of the blocks, with the northernmost block not covered at all and poor coverage near the east coast of Greenland. 141

Report of the Scientific Committee

The four vessels were pooling hydrophones for collecting cetacean sounds, in particular sperm whale. This module was successful, except for one vessel where the mid-frequency sound card was malfunctioning.

T-NASS shipboard general A general review showed that the preparation for the cruise was less than adequate in some areas. The problems identified include in particular the choice of the vessels and the problems with the survey equipment (delivered late and not adequate), which resulted in difficulties in implementing the methodology planned. A list of recommendations was provided to avoid recurrence of these problems in future surveys and enhance their preparation and realization.

The problems noted should not detract from the fact that the T-NASS ship survey was generally successful in achieving its objectives. Cetacean surveys have become increasingly technical, so that the time needed for a thorough preparation has consequently increased. These facts need to be acknowledged and kept in mind for future surveys.

The BT method was still considered the best method available for cases where perception and availability biases were expected and responsive movement was a possibility. The need to use BT as opposed to simpler methods, such as a single platform survey, is to a large degree dependent on the target species and the biases that might be expected. For fin whales preliminary estimates of g(0) have been close to 1 and responsive movement is not expected. Thus a single platform mode would be adequate for this species and more efficient in terms of use of observers. For other species such as minke and pilot whales, g(0) may be low and responsive movement is expected. Therefore a BT type mode is required if absolute abundance estimates are desired for these species.

More problems were encountered in implementing BT in T-NASS than in SCANS II and CODA, primarily due to equipment problems and also to insufficient training and experience. The problems of implementing the method could be overcome in future surveys through improvements in equipment and better observer training. SNESSA had a good success in implementing the BT methodology with an alternative and less technically complex procedure. This alternative should certainly be investigated for future surveys.

Aerial evaluation Preparations for the aerial surveys were generally considered to have been adequate in all cases. Minor modifications were made to the Canadian transect design because of logistical considerations. While minor equipment problems were encountered by all teams, the only serious one was the non-functional SST software in the early part of the Icelandic survey, however this did not detract from whale observations.

The survey platforms were adequate in most respects. The use of the large Arcturus

142

NAMMCO Annual Report 2007 - 2008 aircraft by Canada was unfortunately cancelled. It was considered that this platform was promising for covering large offshore areas and it was recommended that its use should be further investigated.

Lightweight immersion suits (pilot suits) were worn for the first time by observers on Icelandic craft and these were found to be comfortable and convenient. It is undeniable that they could save lives in some situations. In addition one of the observers had received underwater escape training and shared this experience with the crew. These safety measures were also implemented in SCANS II, and it is recommended they be used in future aerial surveys.

The data collection procedures in Iceland and Greenland were similar, but differed from those used in Canada and during SNESSA. The procedure used by Canada does not provide a way to estimate availability bias, which could be an issue, if and when absolute abundance estimates are desired.

Most of the observers employed in the aerial surveys had previous experience, and all received what was felt to be adequate ground and flight training. The value of monitoring the observers closely during the survey and providing feedback to them on a regular basis was again underlined.

Suggestions for improvement/enhancement of future aerial surveys, in particular in Iceland, were given. One of these was to investigate the possibility of using high definition video as a secondary un-manned platform. Generally the aerial portion of T- NASS was considered successful and relatively unproblematic compared to the ship based survey.

Special modifications for harbour porpoises Such modifications were mainly implemented in the Icelandic aerial survey. They included the use of an experienced harbour porpoise observer, a change in altitude from 750 to 600 ft, and the implementation of special strata in some of the fjord systems. The use of an experienced harbour porpoise observer in the Icelandic survey was considered a success in that the number of harbour porpoise sightings increased dramatically compared to earlier surveys. The modifications implemented were thought to be satisfactorily and accepted by the group. They will lead to the first reliable harbour porpoise abundance in the Icelandic coastal area.

T-NASS extension evaluation Three Extension survey efforts covered areas adjacent and to the south of the main T- NASS survey area in 2007: a) Charlie Gibbs Fracture Zone on the North Atlantic Ridge north of the Azores – MAR-ECO, one observer; b) Denmark Strait and the Irminger Sea - ICES Redfish survey, Russia and Germany, two observers on each, but the German trip was cancelled;

143

Report of the Scientific Committee

c) Norwegian Sea - pelagic Norwegian/Russian ecosystem survey, two observers on each (also covered by the Russian Redfish vessel on its way to the Irminger Sea).

The T-NASS Extension was considered a worthwhile addition to the main survey because it provided information on distribution and relative abundance for areas outside the main survey area. The usefulness of the data for deriving estimates of abundance is doubtful. The effort is generally well distributed in areas that could be designated as strata with relatively balanced coverage (except for the MAR-ECO data). However sightings are few except for minke and sperm whales and likely insufficient to be analyzed separately from the main survey data, and the data must be examined in more detail to see if this is feasible. Recommendations were provided to improve the effectiveness of such “opportunistic platform” surveys.

T-NASS acoustic evaluation Although technical problems were encountered on some of the vessels, the acoustic system was generally easy to use and not a heavy burden on the responsible observers. If the data prove to be of value, there will be no objections to continuing to have an acoustic programme in future surveys. An evaluation of the potential of these data is currently being carried out at the SMRU and a decision on further analyses will be made when this process is completed.

General evaluation General T-NASS coordination The WG concluded that the T-NASS coordination provided many advantages over uncoordinated or less coordinated national surveys. The joint survey planning and commonality of methodology allows the combination of the resultant estimates from the coordinated survey, whereas this may not be possible if the surveys were not coordinated.

Mosaic surveys offer many practical advantages in that they can be conducted annually, possibly using the same vessels and observers over long periods, and can be built into annual budgets. On the other hand, the estimates from a mosaic survey apply over several years and must contain additional variance to account for annual variation and long term changes within survey blocks. This additional variance can be great if there are variations in distribution on an annual basis.

The choice between mosaic and synoptic surveys depends mostly on the intended use of the estimates. In a long-term harvest control system for a single species where estimates must be produced for a specific area on a set time schedule, mosaic surveys may be a viable alternative. However, this is not the case for all participants in T- NASS. For some participants it was more important to obtain a snapshot of distribution and abundance of several species, and for this purpose, a synoptic coverage offers advantages. In addition, temporal changes in distribution by comparison to past surveys (as was the case in T-NASS compared with earlier surveys) can more readily be determined with synoptic surveys.

144

NAMMCO Annual Report 2007 - 2008

It was also noted that a synoptic, multi-national survey covering a very large area tended to be more attractive to funding agencies: this was especially the case for the Canadian survey.

The Working Group concluded that the coordination of surveys under the T-NASS banner had been successful and productive. There was a feeling that national interests had dominated in most cases when planning decisions had to be made and implemented; this is understandable since most of the funding came from national research institutes. Nevertheless, a coordinated survey requires some degree of commitment to the survey as a whole.

In this regard, it was agreed that further cooperation in coordinating the output from the T-NASS project was of great importance. It was recommended that a primary publication on the planning, conduct and results of the T-NASS, particularly pertaining to general distribution of cetaceans throughout the entire survey area, including the extension areas, be produced as a priority. CODA and SNESSA agreed to participate in this. In addition products for a more general audience should be developed.

Feedback after the survey and input to website Response to requests from the Secretariat or coordinator on update during and after the surveys was not always satisfactory, which proved very frustrating and led to difficulties in updating the website during the survey, in delays in reporting to authorities and in the presentation of results. Furthermore, accounting could not be updated to reflect actual expenditures.

It was strongly recommended to improve this area in future surveys, especially because funding agencies are interested in seeing the results of their support made public in a timely way.

The NAMMCO Secretariat will continue to maintain a section of the website devoted to T-NASS. It was agreed that, as a starting point, distribution maps for all important species, including sightings from the main T-NASS and extension areas, as well as the CODA and SNESSA surveys, should be developed and posted as a priority. All parties agreed to provide the data to Acquarone in a timely manner.

Cooperation between T-NASS, CODA and SNESSA The cooperation between T-NASS, CODA and SNESSA has been positive from the beginning. The provision of survey reports from both associated surveys to the NAMMCO meeting was acknowledged and appreciated. It was also agreed that sightings data would be shared for the production of general interest publications.

Report of the Scientific Committee

First Meeting of the Working Group on Abundance Estimate (AE WG): Copenhagen, April 8, 2008 (see NAMMCO/17/5 Annex 2) Many of the analyses had not yet been completed and some of the analyses presented were still preliminary.

Fin whales Shipboard Combined single platform estimates were provided for the Icelandic-Faroese area, using 3 degrees of certainty in species identification, and with and without a bias correction for distance estimation. In addition an estimate of g(0) using mark- recapture (or sight-resight) methods was provided. Total abundance for the combined platform estimate using the identification certainty classification most comparable to that used in previous analyses and no correction for bias in distance estimation was 20,644 (95% C.I. 15,053-26,540). The double platform analysis resulted in a mean value for g(0) for the primary platform of 0.87 (CV: 0.06), which is similar to that estimated for 2001 and give a bias-corrected estimate of 18,846 (CV: 0.15). Using a Double platform analysis, the total abundance in the survey area was 23,379 (CV: 0.19) using all effort and non-duplicate detections and 21,341 (CV: 0.17) for the equivalent primary platform estimate using effort conducted in double platform mode only, and without g(0) correction.

Estimated abundance is lower (but not significantly so) than the total estimate for 2001 of 24,887 (95% C.I. 18,186-30,214; Víkingsson et al. in press). Abundance increased rapidly in parts of this area between 1987 and 2001, and it appears that this increase has ceased.

Several potential biases and potential problems were identified, in particular the unconventional choice of last distance estimate from the trackers as sighting distance instead of the initial sighting distance standardly used and the way of applying the g(0) correction factor to the different effort segments. The WG defined the estimates as preliminary and gave suggestions for further work.

The WG also felt that the current confidence index for species identification is confusing and that another system should be used in the future, while ensuring consistency with previous analyses. It also agreed on the necessity of clarifying the notion of group size for this species.

The Norwegian eastern Barents Sea survey had only 15 primary fin whale sightings and an independent analysis will not be conducted. The estimate for the most recent 6 year cycle will be produced within the next year.

CODA experienced similar problems in using the same sighting classification as in T- NASS. The fin whale sightings were grouped in the southern most blocks. A double platform analysis using Mark-Recapture Distance Sampling (MRDS) methods to generate stratified abundance estimates was under way as a first step. It was yet to be decided how to handle the large number of unidentified whales. The detection 150

NAMMCO Annual Report 2007 - 2008 function developed from the mark-recapture analysis will be used for the density surface models.

Aerial Donovan presented the Greenlandic aerial survey results discussed during the IWC RMP meeting held during the previous week. Two estimates have been produced: a) Line transect with correction for perception bias by Mark-Recapture Distance Sampling. This estimate was not accepted mainly because of the very low number of duplicate sightings (eight duplicates). b) Conventional line transect estimate which was acceptable for the purpose of RMP.

Suggestions were made in the IWC-RMP forum for clarification in a future paper to be presented at the IWC Annual Meeting in Santiago in June 2008.

The paper was not discussed at length, but the participants agreed that the conventional line transect estimate was acceptable, although the clarifications asked by the IWC group should also be provided to the WG.

The Greenland fin whale abundance estimate from 2007 was higher than estimates from previous surveys. However the WG noted that some were obtained using a different method and/or carried out in a different period and the survey area did not cover the entire summer range of the feeding stock. The WG therefore considered that there was insufficient information to reach a conclusion about the rate of increase of fin whales in this area.

The preliminary abundance estimate for the Canadian area, using standard method, is 1,008 (95% CI: 571-1786). Overall, the sighting density of fin whales in the Canadian T-NASS was lower than expected. Palka mentioned that the abundance of fin whales in the SNESSA survey area to the south of Canada was higher than expected, so these may have represented animals that were in Canadian waters during earlier surveys. However, bias corrections will have to be applied before any further discussion of the abundance estimate.

Palka reported also that fin whales were recorded for both aerial and shipboard surveys. Neither aerial or shipboard abundance estimates from the 2007 surveys are available yet but the initial impression is that there were more sightings than in previous years in the same area and time.

Minke whales Aerial Corrected estimates were only available for the Icelandic coastal area. The data, analysed following the cue counting methods (Hiby and Hammond 1989, Hiby et al. 1989, Buckland et al. 2001) with the DISTANCE 5.0 software packages and the same cue rate as in previous analyses, yielded a total estimate for the original blocks of 10,680 (95% CI 5,873, 17,121). Post-stratification decreased this estimate by 12%.

151

Report of the Scientific Committee

This estimate may be negatively biased because of visible cues missed by the observers near the plane. The 2007 point estimate is 24% that from the 2001 survey and the decrease is significant (P<.05). Abundance was lower in 2007 than 2001 in all blocks but one. These estimates were accepted as final by the WG.

There was an obvious difference in abundance compared with the previous survey in 2001. These differences in abundance could not be directly ascribed to changes in survey design or execution. Possible reasons for the decrease could not be determined definitively, but include population decrease, changes in spatial distribution (i.e. more minke whales outside the survey area) and/or changes in the timing of migration to or from the survey area. A possible change in seasonal distribution is consistent with recent changes in the ecosystem of the Icelandic continental shelf area perhaps as a result of higher sea temperatures. Indications of recent changes include a northward shift in distribution of several fish species, low abundance of sand eel and capelin and breeding failure in seabirds.

Shipboard No analyses had been performed on the T-NASS shipboard data yet. In the Icelandic- Faroese area, there were fewer sightings than in previous surveys, but there was large gap in effort in areas of usually high density and the analysis would probably not generate a reliable estimate. The Norwegian survey indicated that sighting distribution between the 1995 and the 1991-2001 survey cycles was very similar, but that there was a shift westwards.

There were ca 29 unique sightings of minke whales made in the Greenlandic area. The WG recommended that analysis of the data be carried out as soon as possible.

Discussion The WG discussed at length possible explanations for the decrease in minke whale abundance as observed in the Icelandic coastal area. A change in distribution could not be inferred from the surveys data. But some of the areas known as high density had a low or null coverage. It was pointed out that the catches in Norway and Iceland could certainly not explain such a decline. The group decided that at least two attempts to find an explanation could be made: • The analysis of the T-NASS Extension minke data in the Norwegian Sea, an area which was not covered by the dedicated survey, as a comparison in sightings rate could inform on change in relative densities there. • A spatial analysis of present and past minke data could allow identification of predictors of minke distribution and reveal whether minke whales could have been expected in 2007 in areas which were not covered by the 2007 dedicated survey e.g. the northern Icelandic blocks.

The WG recommended that these two analyses be carried out as soon as possible and underlined the importance of synoptic surveys, relative to mosaic surveys, in interpreting shifts in distribution.

152

NAMMCO Annual Report 2007 - 2008

Humpback whales Some problems were identified with the analysis provided for the Greenlandic aerial survey, which had to be solved before an estimate could be accepted.

Humpbacks were not detected in the Denmark Strait area, but coverage had been very poor in this area. The number of sightings in the blocks north and west of Iceland and during the aerial component warrants further analysis, but the geographical overlap with the ship survey should be taken into consideration.

A preliminary uncorrected estimate was provided for Canadian areas, where there were quite a lot of sightings. Preliminary results from SNESSA pointed to an increase abundance compared to the previous survey.

Pilot whales A number of sightings were made both in the T-NASS and the CODA surveys. It was agreed to combine data from both surveys, to produce a common detection function. It was suggested that the Faroese contract the analysis externally, and if possible in cooperation with CODA. Estimates would be also obtained from the Canadian and SNESSA data.

General comments were made on the difficulty to identify groups and group sizes for this species.

Harbour porpoises The Icelandic aerial survey generated 119 sightings, which are a very much higher number than in previous similar survey in 2001. Harbour porpoise were a target species for T-NASS and this estimate will represent the first reliable estimate of harbour porpoise in coastal Icelandic waters.

In Greenland, the shipboard survey had only 8 animals sighted but 46 were sighted in the aerial survey. The WG recommends that Greenland develops a reliable abundance estimate for this species. It also suggests that Greenland coordinates the analysis with Iceland, as there is a high degree of similarity between the two surveys (similar methods and some of the same observers). It was noted that the harbour porpoise was the species with the highest number of sightings (46) in the Greenlandic aerial survey 2007.

In Canada, fewer porpoises were observed in 2007 than in the 2002-2003 aerial survey around Newfoundland, and in the larger-scale aerial surveys in the Gulf in 1995 and 1996. SNESSA had a lot of sightings in both surveys, but there was no indication of variation in population size.

Other species Sightings were not very abundant for most of the other species. For sperm whales, both acoustic and visual analyses should be performed and compared with earlier surveys, and also include the extension data. There was a fair amount of white-beaked 153

Report of the Scientific Committee dolphin data, and the WG recommended that abundance estimates be produced for this species.

T-NASS extension Extension data should be reviewed in the context of the whole T-NASS survey to assess which analyses are worth conducting. In particular, minke whale sighting rates in the Norwegian Sea should be compared with earlier surveys in the same area, to see whether they are comparable taking into account the different methodologies.

Cooperative analysis The group reiterated its decision to publish a common distribution paper and decided to create an e-mail discussion group for questions and discussion related to the analysis of the T-NASS, SNESSA, and CODA survey data. Spatial modelling was recommended for fin and humpback whales.

Publication of results See under point 11.2.

8.2 Cooperation with CODA and SNESSA For the first time a NASS survey cooperated with a European – CODA - and an American – SNESSA – concomitant survey, ensuring a coordinated effort and the broadest synoptic coverage possible.

The Committee commended this new cooperation, as well as the cooperation with other non-cetacean programmes, which was considered extremely valuable and positive. The fact that SNESSA, CODA and NAMMCO had agreed to publish as a priority, a joint primary publication pertaining to the general distribution of all cetaceans species throughout the entire survey area, was also considered as a very positive step. The Committee recommended that the publication be given a high priority.

8.3 Archiving T-NASS data The delegates were reminded that T-NASS is a part of the ESSAR-IPY project and that IPY data policy involves a common data archiving and availability policy.

It was noted that data from T-NASS will be submitted to the IWC for archiving and use within the RMP.

The Scientific Committee recommended that T-NASS data be transformed to a format similar to the one employed by the IWC and be archived at the NAMMCO Secretariat with the necessary clauses for use restrictions.

8.4 New requests and future work No special requests were presented other than the continuation of the abundance estimate work. Data on fin, minke and pilot whales should have highest priority in the analysis, followed by humpback whales and harbour porpoises. 154

NAMMCO Annual Report 2007 - 2008

The acoustics data from T-NASS have been sent to SMRU in St Andrews for quality evaluation.

The Committee recommends the analysis of sperm whale T-NASS acoustic data. Furthermore, the Committee encourages the participants in the T-NASS surveys to prepare and make available feedback on progress in this project to the Secretariat for drafting a common press release and for updating the T-NASS web space. It also reiterated its previous recommendation that the publication pertaining to the general distribution of all cetacean species throughout the entire survey area be given a high priority by all countries and that all participants forward the data to the Secretariat in a timely fashion.

The Committee warmly thanked the T-NASS Coordination Staff and the project Participants for their work.

9. CETACEANS STOCKS - STATUS AND ADVICE TO THE COUNCIL

9.1 Fin whale 9.1.1 Update on the stock delineation question Víkingsson referred to the instance that genetic and non-genetic data relevant to stock assessment were presented to the joint NAMMCO and IWC fin whale working group in 2006. Results from subsequent genetic analysis generally support a lack of genetic divergence for fin whales across the North Atlantic (SC/15/18). The new genetic studies did not change the conclusion reached by the working group and are compatible with all stock structure hypotheses presented there. Results will be presented to the IWC SC.

The SC noted that here had been no progress since the 2006 fin whale WG meeting in genetic analyses of the Faroese fin whale biopsy samples taken in 2000-2001. In the light of previous indications that Faroese fin whales are very different from other N.Atlantic fin whales, the SC urges rapid completion of the genetic analysis of these samples using techniques compatible with those used currently on Icelandic samples. If results indicate that there are indeed genetic differences that are significant, this will have important implications in stock analysis currently ongoing in implementation processes.

9.1.2 Update on the work on relatedness The two extreme hypotheses postulate either the existence of only one stock or the existence of multiple stocks, but where the evolutionary time since stock separation has been too short to be detected by standard genetic methods. A new, more sensitive method to investigate stock separation for closely related stocks, which employs the levels of kinship at the brother-sister or parent-offspring level, has been developed by Hans Skaug and is being applied to fin whale data.

9.1.3 New estimates from T-NASS 155

Report of the Scientific Committee

Víkingsson reported on the new estimate from Icelandic shipboard surveys presented at the April 2008 meeting in Copenhagen of the Working Group on Abundance Estimates (SC/15/10). The survey was performed using standard line transect methods and the calculations were made using Distance. The same methods as used in 2001 were employed, bearing in mind the possibility of comparisons between the point estimates. The resulting estimate numbered 20,644 (95% CI 15,053-26,540) and this figure is not significantly different from the previous assessment in 2001. A new estimate of g(0) was 0.87 (CV: 0.06).

Potential biases were accounted for in the calculations. G(0) may be overestimated because no covariate was used. Some other potential biases were also recognized, and they should be investigated. These include further evaluation of biases in distance estimation, responsive movement and uncertainty in species identification. Also the impact of using the location of the sighting the closest to abeam instead of the initial sighting, as standard, should be investigated.

The Committee welcomed this result and agreed that this estimate is “preliminary”. It recommended that the analysis identified be carried out as soon as possible. The final estimate could be directly reviewed by the fin whale assessment group.

The Greenland estimates based on conventional line transect methods from the 2007 aerial survey, resulted in 4,660 (95% CI: 1,890-11,500) which was higher than the abundance estimate of 2005, accepted by the IWC, which was 3,200 (95% CI: 1,400- 7,200).

The Working Group accepted the 2007 estimate for Greenland fin whales, and this was adopted by the SC.

The Norwegian estimate for the northeast Atlantic, including the whole 6 year cycle, will be available in the course of the next year.

Canada presented preliminary estimates that have yet to be corrected for bias. Estimates of abundance will shortly also become available from the SNESSA and CODA surveys.

9.1.4 Update on other progress Russian Federation: Fin whales are a rare species in the Barents Sea, but in the course of 2006-2007 there has been an increase in the frequency of sightings of fin whales in August–September during the Ecosystem Surveys and in the summertime coastal zone observations.

The Ecosystem Surveys have taken place later than T-NASS and in the time lag between the two surveys, the distribution of the whales could have shifted significantly. Furthermore, the T-NASS and Ecosystem Surveys’ efforts and observation protocols are very different.

Faroes: 156

NAMMCO Annual Report 2007 - 2008

A catch statistics database for the North Atlantic is under compilation, and the work will be completed in a month from this meeting. When the work is completed, the database will be deposited at the NAMMCO Secretariat.

9.1.5 New request and future work The Committee recommended that recent indications of changes in distribution (i.e. spatial dynamics) related to environmental changes, should be taken into account when designing future surveys.

With regards to an assessment for the Northeast Atlantic stocks of fin whale, such an assessment can be initiated when the 2007 estimates are finalized. This could be done in conjunction with a new assessment of the central stock subsequent to the new 2007 abundance estimate. The Committee recommended that this be done before the next SC meeting.

9.1.6 Update on the CITES and IUCN status reviews In 2006, the Scientific Committee evaluated the status of fin whales in the Central North Atlantic as part of a periodic review under the Animals Committee of CITES. After reviewing biological information, CITES criteria A, B and C, and based on all available information, the NAMMCO Scientific Committee recognized that this species does not meet any of the biological criteria for listing in Appendix 1 (species in danger of extinction). The review process was stopped within CITES, in the middle of the review, for reasons that are unknown to the Scientific Committee.

The SC requested the Secretariat to find out the outcome of the meeting of the IUCN special group meeting regarding fin whales and their status.

9.2 Humpback whale 9.2.1 Revised Greenlandic 2005 estimate The 2005 estimate of humpback whales from Greenland was presented neither at this meeting nor at the AE WG, and was therefore not discussed.

9.2.2 New estimates from T-NASS Uncorrected abundance estimates from aerial surveys conducted off West Greenland were reported for 1984, 1987, 1988, 1989, 1993, 2005 and 2007, with also a fully corrected 2007 estimate of 3,820 (CV=0.51, 95% CI 1,489-9,803). The estimates are preliminary and following some adjustments of the analyses, five final and likely acceptable estimates are expected later this year (a joint 1987-89 uncorrected estimate, uncorrected estimates for 1993, 2005, 2007, and a fully corrected 2007 estimate).

The 2007 estimate was not accepted as final by the AE WG.

9.2.3 Review of the advice on catch limit for W. Greenland given in 2006 In 2006, the SC gave interim advice on the number of humpback whales that could be safely taken. The estimate of the 2007 survey, though not definitive, was higher than the estimate in 2005 on which this advice was based. Therefore, considering that in spite of the uncertainty of the 2007 estimate, there is no immediate indication of a 157

Report of the Scientific Committee population decrease, the Committee did not see the reason to reconsider this interim advice until a proper assessment has been carried out.

9.2.4 Update on other progress (Greenlandic acoustic/tagging and Norwegian biopsy/photos) Haug reported that Norway is continuing the photo-ID and tagging studies. There are no new progress reports on these. Furthermore, biopsies have been taken for stock structure studies.

Rosing-Asvid reported that in Greenland, multi-sensor archival tags (DTAGs) with a pressure sensor and three-axis accelerometers and magnetometers were used to study in detail the kinematics of lunge feeding in humpback whales. This study revealed that there is little evidence that whales accelerate forward before mouth opening to lunge at prey schools. There are on the contrary, indications that they adjust their fluking to match increased drag from the opening of the mouth to maintain a steadier and slow speed though the lunge. It was concluded that humpback whales seem to gulp rather than lunge at prey laden water masses. A small number of conventional tags were also deployed during the summer 2007 in Nuuk Fjord. In the same area, 55 ID photos of humpback whales were collected during 2007, leading to the identification of 20 individuals in Nuuk Fjord. Based on these data it is possible to infer that the whales migrate in and out of the fjord throughout the season, and that some individuals return to this specific location indicating a year-to-year site fidelity.

9.2.5 New requests and future work The Committee recommended that biopsies and photo-ID data from all the areas be analyzed before the initiation of a new assessment.

Bloch is ready, after a request and in collaboration with the IWC office, to provide a historical North Atlantic catch list for humpback whales, if this was desirable and of any use in the work of assessment.

9.2.5.1 Possible cooperation with the IWC on a Humpback Whale assessment After careful consideration, it was concluded that it is not helpful for NAMMCO to have a joint assessment with the IWC for Greenlandic and Icelandic humpback whales, because the AWMP for Greenland and RMP for Iceland are two different processes in the IWC system. Furthermore, the RMP can take up to six years to be completed and could delay the production of an assessment from NAMMCO.

It was noted that the novelty of the humpback whale assessment will surely require more than one meeting. The Committee recommends that the preliminary work (state of the art with evaluation of available information) should be done in connection with the fin whale assessment meeting before a separate meeting schedule is set up for humpback whale assessment alone.

It also recommended that abundance estimates for humpback whales from all surveys (2007 and older) should be made available to the fin whale assessment group.

NAMMCO Annual Report 2007 - 2008

9.3 The remembered whale: Sei whale 9.3.1 New estimates from T-NASS Iceland reported very few sightings of sei whales. Greenland reported only five. An abundance estimate from these data would probably lead to a large confidence interval.

Bloch commented that sightings of sei whales are very variable in the Faroes. It seems that this species ranges more south than the NAMMCO area and that only occasionally it extends further north. Lockyer commented that during the whaling period of the 1970s and 1980s off Iceland, sei whales were unpredictable in their presence and density, resulting in highly variable catches.

Lockyer commented that the estimates of sei whales that can be derived from T-NASS data are unlikely to be valid unless there are data from blocks further south. The sei whale is in general a more southerly species with incursion to northerly waters occurring in years when perhaps sea temperature and prey abundance are favourable.

CODA had 18 sightings of sei whales and it is recommended that T-NASS sei whale data are combined with CODA sei whale data for analysis.

9.3.2 Update on research in the NAMMCO countries Greenland’s shipboard estimate from 2005 was not formally accepted. The estimates from the NASS (NASS 1989 had sei whales as a target species) gave a minimum estimate as sei whales were most abundant at the southernmost border of the NASS area.

Bloch is ready, following a request and in collaboration with the IWC office, to provide a historical North Atlantic catch list for sei whales, if this was desirable and of any use in the work of assessment.

9.3.3 New request and future work With regards to a status of the species in East and West Greenland waters, the Committee recommends that the assessment group for fin whales make a state of the art investigation about the possibility of providing this status using all available data.

The SC recommends making all sei whale survey data available to the fin whale assessment group.

9.4 Minke whale 9.4.1 Update on stock delineation and relatedness Haug reported that genetic studies based on data from the DNA register reveal very little evidence of genetic structuring among the animals in the North East Atlantic from the North Sea to Spitsbergen, including the area around Jan Mayen (Hans Skaug, pers. comm. unpublished study that will be presented at the IWC).

159

Report of the Scientific Committee

Víkingsson mentioned that Pampoulie et al (SC/15/18) had similar results about the lack of evidence of genetic structuring in the population over the whole North Atlantic.

9.4.2 New estimates Aerial surveys from 2005 in Greenland gave a fully corrected estimate of 10,800 (95% CI: 3,600-32,000). This estimate was endorsed by the IWC in Anchorage in 2007 but was not presented to a NAMMCO forum.

Only the Icelandic aerial estimate from T-NASS in coastal Icelandic waters was presented at the AE WG in Copenhagen in April 2008 (SC/15/10).

Víkingsson presented the Icelandic estimate of minke whale abundance from the Icelandic aerial survey area. The total estimate for the original blocks is 10,680 (95% CI 5,873-17,121). Post-stratification decreases this estimate by 12%. This estimate may be negatively biased because of visible cues missed by the observers near the ‘plane. The 2007 point estimate is 24% that from the 2001 survey and the decrease is significant (P<0.05). Abundance was lower in 2007 than 2001 in all blocks but one. A pronounced difference in sighting rate was detected between the two primary observers. Analysis using only data from experienced minke whale observers resulted in an estimate of 15,055 (95% CI: 6,357-27,278). The reason for the decrease cannot be determined definitively, but possibilities include population decrease, changes in spatial distribution (i.e. more minke whales outside the survey area) and/or changes in the timing of migration to or from the survey area.

Haug showed evidence of huge distributional changes in unrestricted whaling catches of minke in the Barents Sea between 1952 and 1980. Such changes can also happen over a much shorter time frame. Prey distribution seems to govern whale distribution.

The SCANS survey in 1994 and 2005 also indicated significant changes in spatial distribution between the two surveys (SC/15/O17 and O18).

It might be necessary to reconsider the Icelandic shipboard survey strategy. Presently the shipboard surveys proceed in weather conditions up to Beaufort 6, and effort in these conditions probably misses minke whale sightings, thus reducing the reliability of the shipboard estimate. It was noticed that the aerial survey covers a relatively small part of the Central North Atlantic stock area. Extensive areas around the aerial survey blocks had little or no shipboard coverage in conditions suitable for minke whale detection.

Reproductive failure and/or increased mortality were considered unlikely explanations for the apparent decrease in abundance. An adult mortality of 20%, with zero reproduction, would be required for such a reduction. The Committee considers that a mortality hypothesis is unlikely and that the recent catches (200 over 5 years) are too small to account for the missing animals. The most likely hypothesis is an ecological one that assumes that the whales are elsewhere during the time of the T-NASS surveys. It was noted that there have been significant shifts in diet composition of 160

NAMMCO Annual Report 2007 - 2008

Icelandic minke whales since the start of the Icelandic research programme, and prey abundance and distribution (notably of capelin and sand-eel) may also influence whale redistribution.

Haematological examinations from the Icelandic Scientific Whaling Programme showed no unexpected results that could indicate declined health status in the population. The same samples from the Scientific Whaling Programme should be analysed for body condition to determine if there are trends revealing decrease in fitness, even if a mortality hypothesis is considered unlikely to explain the diminished abundance.

Rosing-Asvid noted that NAMMCO’s engagement to ecosystem approach to management calls for a more comprehensive investigation of the North Atlantic system. This would be under the jurisdiction of the Working Group on Marine Mammals and Fisheries Interactions. However, this investigation should strive to encompass the whole NAMMCO area.

The Committee reiterated the importance of synoptic surveys in interpreting shifts in distribution.

Annual Norwegian-Russian Ecosystem Surveys in 2006 and 2007 show an increase in numbers and distribution area for minke whales that could provide an index of distribution for these whales.

9.4.3 Estimate from SCANS II The design-based abundance estimate is 13,281 (95% CI: 6,663-26,471). The data were truncated at perpendicular distance 870m. The best model included perpendicular distance only. No group size correction was applied since the majority of sightings were single animals. Variances were based on the empirical variance in estimated density between samples (SC/15/O17).

9.4.4 Update on progress The sampling within the Icelandic research programme was completed in 2007 and samples are being analysed. A review of the main results is scheduled for 2010 (See 6.4).

9.4.5 Future work The Committee endorsed the recommendations of the Working Group: • Sighting rate for the T-NASS Extension survey in the Norwegian Sea should be calculated and used for comparison with the other T-NASS areas and previous estimates in this area. • A spatial analysis of both the historical and present survey data including the Norwegian data is recommended to check whether the missing whales could be predicted to be in the areas not covered by the T-NASS survey.

All the abundance estimates from the Working Group on Abundance Estimates (AE WG) for the Icelandic coastal area were accepted, but none was indicated as the best. 161

Report of the Scientific Committee

The Committee urges that the AE WG selects which one should be used as a point estimate in future assessments.

The Scientific Committee also recommends that the analysis of all the minke whale data from the Greenlandic (aerial and shipboard), T-NASS Extension and Icelandic (shipboard) surveys on minke whales be undertaken as soon as possible.

The Committee recommended an investigation of potential changes in the ecosystem within the framework of the Working Group on Marine Mammals and Fisheries Interactions.

The SC recommended that spatial distribution analysis should be undertaken, and that body condition indices in the Barents Sea and Iceland should be published when available.

9.5 Narwhal 9.5.1 Update on the 4-year Greenlandic research programme Rosing-Asvid reported that a summer survey was flown in 2007 in the Melville Bay and Inglefield Bredning area. Data from this survey is currently being analysed to develop fully corrected abundance estimates. The dataset includes 328 sightings of which 32 were from the Melville Bay area.

A narwhal tagging programme has been run in West and North Greenland. Six animals were equipped with harpoon-delivered satellite transmitters in the Qaanaaq area in August 2007, while three animals were instrumented with backpack transmitters in September 2007. Another animal was tagged with a backpack transmitter in the Uummannaq area in November 2007.

An aerial survey for narwhals is planned for 2008 in East Greenland and an East Greenland narwhal tagging programme is planned, depending on funding.

Similarly, surveys in 2009-2010 in the North Water area are planned for both Walrus and Beluga, depending on funding.

Lydersen mentioned that two publications on narwhals from Svalbard had been produced since the last meeting: 1) Including satellite tracking and diving data (Lydersen et al 2007). These were collected for up to 46 days and present movement and diving patterns. 2) An investigation of POP pollution in blubber (Wolkers et al 2006). It seems that PCBs, PBDs are 3 times higher in sub-adult narwhal than in sub-adult belugas. This supposedly reflects a difference in diet since the detoxification capacity of the two species is probably very similar.

9.5.2 New estimates from the March 2006 and August 2007 surveys No estimate was presented

162

NAMMCO Annual Report 2007 - 2008

The Management Committee requested a review of the 2007 narwhal and beluga survey plans by the T-NASS committee. It was noted that this had not been done, since the plans had not been presented to the T-NASS committee.

9.5.3 NAMMCO and JCNB Joint Working Group The SC considered that there were enough data to warrant an update of the assessment of narwhal abundance and recommended that the NAMMCO/JCNB meet before March 2009 to allow the use of this assessment in the new quota series.

9.5.4 Future work The Committee was informed that the narwhal quotas for West Greenland for the period from 2004 to 2008 were as reported in Table 3 (below).

The Committee noted that the catch quotas are still higher than the advice given of 135 (NAMMCO 2003, 2005, 2006) and expresses continued concern about the quota level. At the same time, the Committee recognizes that the preliminary data on abundance of narwhal and beluga show higher estimates and urges Greenland to submit fully corrected estimates derived from the March 2006, August 2007 and 2008 surveys to the Joint Working Group.

Period Quota Comments July 2004 – June 300 2005 July 2005 – June 260 later raised 310 2006 July 2006 – June + 115 for Melville Bay + 10 to be distributed in the 217 2007 spring if necessary July 2007 – June 200 + 100 for Melville Bay 2008

Table 3. West Greenland quotas for narwhals (the quota for 2006-2007 had been initially set to 385 animals, but was lowered to 217 for West Greenland to compensate for extra animals taken in the previous period).

9.6 Beluga 9.6.1 Update on progress Rosing-Asvid reported that a beluga tagging programme for West Greenland is planned for 2008-2009. This item also depends on funding.

Lydersen mentioned a recent genetic study that shows that Svalbard belugas (42 animals) are clearly distinct from West Greenland belugas (79 animals). Svalbard and White Sea animals (5 animals) seem to be more closely related to the Beaufort Sea than the West Greenland animals.

9.6.2 New estimates from the March 2006 and August 2007 surveys No new corrected estimate from these surveys is available 163

Report of the Scientific Committee

As for narwhals, the Management Committee requested a review of the plans for the 2007 narwhal and beluga survey by the T-NASS committee. It was noted that this had not been done (see under 9.5.2).

9.6.3 NAMMCO and JCNB Joint Working Group See point 8.5.3 above on narwhal

9.6.4 Future work Age determination validation in beluga (and narwhal): expert meeting, workshop? An Age Determination and Methods Validation workshop is needed and NAMMCO could act as the organizer at the discretion of the NAMMCO/JCNB Committee. Such a workshop should not only include tooth layer reading but also other techniques such as • Aspartic acid racemisation – especially for narwhal • Fatty acid ratios in blubber

Lockyer noted that although narwhals and belugas are often grouped together for aging purposes, they are separate species and methods should be pooled carefully. Furthermore, she pointed out that tooth-reading based age determination of belugas is going to be important also in the future and in the event of adoption of new techniques for standardization purposes. The necessity for such a workshop was transferred for discussion to the NAMMCO/JCNB Committee.

Lydersen mentioned that Norway for several years had tried to get funding for a joint Norwegian-Russian genetics and satellite tracking study of belugas without any success. It is highly recommended that this project be funded.

The Committee was informed that the beluga quotas for West Greenland for the period 2004-2008 have been set according to Table 4 (below).

Period Quota July 2004 – June 2005 320 July 2005 – June 2006 220 July 2006 – June 2007 140 + 20 for Qaanaq July 2007 – June 2008 165

Table 4. West Greenland quotas for beluga.

The Committee commended Greenland for their management efforts to improve the conservation status of beluga. Nevertheless the Committee remained concerned that the total removals were still above the recommended level of 100 for West Greenland (2000 & 2001). At the same time, the Committee recognizes that the preliminary data on abundance of narwhal and beluga show higher estimates and encourages Greenland, as for narwhal (point 8.5.4 above), to submit fully corrected estimates

164

NAMMCO Annual Report 2007 - 2008 derived from the March 2006 and August 2007 surveys to the NAMMCO/JCNB Working Group.

9.7 Bottlenose whale 9.7.1 Update on progress Mikkelsen reported that no progress had been made on this species in the Faroe Islands. Samples from three stranded animals in 2007 were taken but have not yet been analysed.

Zabavnikov mentioned that there has been an increase in sightings of bottlenose whales from fisheries vessels in the Barents Sea. In 2007 there were 30 reported observations in the Western and North Western part of the Barents Sea.

Víkingsson noted that Icelandic dietary data for bottlenose have been analysed by a student but that these data are not available yet.

Some data on distribution may come from the T-NASS and CODA surveys.

The Committee strongly recommends that the Faroese and Icelandic data on bottlenose whale feeding be made available as soon as possible.

9.7.2 Future work The acoustic recordings from T-NASS 2007 will be screened for data on this species.

Sightings made during T-NASS will be reported as distribution data only because there are not enough points for an abundance estimate.

9.8 Killer whale 9.8.1 Update on progress Lydersen reported two observations of killer whales north of 80°N 0°E in mid-March 2008 and on a film that can be found on www.youtube.com/watch?v=eYq39tFNISk about a minke whale being attacked and eaten by killer whales off Ny Ålesund on Svalbard.

Haug reported that changed winter distribution of herring has changed the distribution of killer whales in Norwegian waters.

Zabavnikov reported that killer whale sightings in the Barents Sea area are both in offshore and coastal areas and that killer predation on harp seals has been observed.

Mikkelsen mentioned that behaviour of killer whales around the Faroes suggests that they are looking for grey seals in near shore areas and killers have been observed to predate on eider ducks and other birds.

9.8.2 Future work Víkingsson reported that a study involving photo-ID and genetics has been initiated by cooperation between the MRI in Reykjavik, the University of Aberdeen and Tiu 165

Report of the Scientific Committee

Similä under the supervision of Paul Thomson. This study involves the use of North Atlantic data from Iceland, Norway and Scotland. The Scientific Committee recommended that pictures taken during the T-NASS survey be made available for this project.

The Management Committee requested the SC to review the knowledge on the abundance, stock structure, migration and feeding ecology of killer whales in the North Atlantic, and to provide advice on research needs to improve this knowledge with priority to killer whales in the West Greenland – Eastern Canada area. At the last meeting, the SC concluded that there was not enough information to carry out the assessment at this time, particularly for the West Greenland area. This situation remains unchanged.

Lockyer mentioned that the IWC reviewed killer whales as a special topic under the Subcommittee on Small Cetaceans in 2007 and concluded that there was insufficient data for an assessment at the moment. The Committee did not intend to make a review of this species until new data are available.

9.9 Pilot whales 9.9.1 New estimates from T-NASS and CODA Desportes mentioned that the methodology employed in T-NASS was designed for pilot whales as well as other key species and the coverage was sufficient for an estimate of this species. T-NASS was planned to cover the area of the 1989 survey.

The SC recommended that data from both aerial and shipboard surveys should be included in the analysis for pilot whales after being grouped and validated. Mikkelsen will take the lead for this task.

Kelly Macleod from SMRU will be charged with the task of estimating abundance and modelling the spatial distribution of pilot whales including Icelandic, Faroese and CODA data. There are indications that this process will likely be completed and an estimate be available by the end of 2008.

9.9.2 Monitoring programme for the Faroes Lockyer presented the report from the WG on pilot whales (see NAMMCO/17/5 Annex 3), which had corresponded by email before this meeting and convened during the meeting of the SC. She provided the background to the development of this WG which had been established in response to a request from Council to the SC “to develop a proposal for the details of a cost-effective scientific monitoring programme for pilot whales in the Faroes.” The WG had decided to define their work and concluded that, although this was not expressed directly in the Terms of Reference, the aim of the monitoring programme was to assess the continued sustainability of the Faroese catch and that “there should be both a long-term and short-term monitoring directed to determining the continued sustainability of the Faroese catches”.

The WG summarised the previous assessments from NASS surveys, and also other previous data on catches and investigations. Although new abundance estimates 166

NAMMCO Annual Report 2007 - 2008 became available in 1995 and 2001, the accepted best estimates still refer to the combined 1987 and 1989 estimates, meaning that there had been no new assessment accepted in 20 yr. The estimate then was 778,000 (cv 0.295).

The WG reported that a basic catch reporting system was in place and had been for many centuries, providing a long catch history series where numbers of catch,, individuals per catch, and animal size in the traditional skinn value, date and place were recorded. In the last 20 years, individual length and sex were also reported.

Whilst the WG regretted that it was unable to conclude its work at this meeting, it nevertheless made some important recommendations and suggestions for designing and implementing a monitoring programme. The main outcome was a table summarising goals, sampling methods, skills and experience required, relative costs, time needed to obtain meaningful results, limitations and likely success, and relative overall priority in enabling the programme to achieve the main objective (Annex 1 of NAMMCO/17/5 Annex 3).

Lydersen commented that contaminants are not a useful method for monitoring animal health status and recommended routine blood screening as an inexpensive tool for assessing health of animals (see Tryland et al. 2006a and b).

Satellite tagging was noted as being potentially very useful in the longer term. If the main goal was to follow movements and determine home ranges, then the smallest tags (which would minimise damage from social interaction), and less expensive tag models that only recorded position and that had proved very durable (active for a year or more) in some species, were the best choice in this situation. Mikkelsen confirmed that when animals in a pod were corralled and tagged, all animals in the pod were released together.

Of all the goals and methods listed in the Annex 1 of NAMMCO/17/5 Annex 3, the SC identified two that were absolutely critical and of the highest importance to a monitoring programme. These were the official logging of all catches and the conducting of regular surveys for abundance estimates at approx. 6 yr intervals. The assessment of pilot whales has already been prioritised for the T-NASS data, and should include both T-NASS and CODA abundance data (see point 8.9.1).

The WG recommended that work that could be started immediately before a final programme could be detailed and approved, included: • Calculation of indices of abundances from previous NASS surveys – 1987 and 1989, 1995 and 2001, as well as 2007. • Full documentation and statistical analysis of historic and present catch series – including length / skinn composition and sex ratio of pods.

The first of these would enable all surveys – however poor in area coverage, to be used in monitoring trends in abundance. This would also help to minimize costs in the future should only partial area coverage be feasible during surveys. However, ecosystem changes might also influence whale distribution and these indices should be 167

Report of the Scientific Committee used with caution. The second would involve analyses over time to detect oscillations and trends in the catch structure. Such an analysis is already planned to be undertaken by Bloch and Witting.

9.9.3 New requests and future work The SC thanked the WG for its work, and recommended that calculation of new abundance estimates be prioritized using T-NASS and CODA data, and that analyses of indices of abundance be undertaken as proposed by the WG. The SC also recommended that new analyses and re-analyses of catch data and statistics be undertaken as a priority. The Committee recommends that a new assessment be made when the new estimates will be available.

The SC endorsed the recommendation of the WG on pilot whales that all survey plans, assessments, data analyses of catch and biological studies be routinely presented to the NAMMCO SC for evaluation, and that there should be an establishment of a standing WG on pilot whales that would meet periodically (e.g. every few years) to examine the information.

The SC requested the WG on pilot whales to reconvene as soon as practicable in order to complete its work and recommendations, taking into account comments that had been made during the main meeting.

Post script: The WG on pilot whales reconvened after this SC meeting, in July 2008 in Copenhagen and produced a concluding report with recommendations on establishing a monitoring programme with various options involving different levels of monitoring and their related costs and benefits. This report was circulated among SC members and approved by correspondence. The WG report was then incorporated into the main SC report as an Addendum, which was presented to Council in August 2008 (NAMMCO 16). The recommendations from the WG were thus taken up for consideration in Council. The work of the WG is thus concluded for the present until Council request further action on implementation of the programme.

9.10 White-beaked, white-sided dolphins and bottlenose dolphins 9.10.1 Update on progress Lagenorhynchus spp. The Committee noted that any assessment of these species cannot be made before the end of 2008. It was also noted that there seem to be sufficient sightings from T-NASS surveys to generate an abundance estimate for at least white-beaked, and maybe white-sided dolphins (Iceland).

Mikkelsen reported that there had been no catches of white-sided dolphins in 2007 in the Faroes. No white-beaked dolphins have been caught in the Faroes.

Ólafsdóttir mentioned that there has been no progress on this species in Iceland since the last report. Samples of white-beaked dolphins are still being taken, but recently 168

NAMMCO Annual Report 2007 - 2008 only from strandings. Samples on diet and biological parameters from 70-100 animals have been analysed. A photo-ID project on white-beaked dolphins in Faxaflói and Húsavik area has been completed. This project was based on images of dorsal fins.

Víkingsson mentioned a tagging project of white-beaked dolphins in Faxaflói by an international group in 2006 which involved the capture and release of animals. The project investigated the characteristics of their acoustic and diving behaviour by employing conventional satellite transmitters and DTAGs.

Greenland reported that there is no work in progress on any of these species.

Tursiops Mikkelsen reported that this species is occasionally observed in the Faroes. A few bottlenose dolphins are caught in the traditional drive fisheries.

The Committee noted that there are still not enough data to complete an assessment.

9.10.2 Future work There is still insufficient information on white-sided dolphins, but the SC recommended that data from the T-NASS survey be analyzed for this species.

Mikkelsen reported that a satellite tracking project for white-sided dolphins is planned for the Faroes. This study will employ tags from Wildlife Computers and aims at a tag life of 200 days. The programme on the biology of the white-sided dolphin in the Faroes is in the analysis stage.

The SC recommended that white-beaked dolphin data from the Greenlandic aerial survey and the Norwegian shipboard survey be analysed.

9.11 Harbour porpoise 9.11.1 Estimate from T-NASS Iceland, as well as Greenland to a lesser extent, have implemented modifications in their survey design to accommodate this species, as requested by the Council. This will lead to the first reliable abundance of harbour porpoises in Icelandic coastal area.

The Committee recommends that Greenland and Iceland coordinate the analysis of harbour porpoise data from the T-NASS surveys.

9.11.2 Update on the results of SCANS II The abundance estimates within the 1994 survey area were calculated from the 1994 and 2005 data using density surface modelling; the estimates were 345,132 (95% CI: 272,904 – 479,222) and for 315,027 (95% CI: 201,507 – 395,077) respectively. Although the overall abundance estimates are not significantly different, there was a big difference in regional abundance between the 1994 and 2005, with lower abundance in the northern North Sea and a higher abundance in the southern North Sea and Celtic Sea in 2005.

169

Report of the Scientific Committee

9.11.3 Future work Mikkelsen reported on plans for tagging of harbour porpoises in the Faroes and for a shipboard survey on the Faroese plateau in 2008-2009. It was recommended that this survey be designed to be compatible with SCANS II and other harbour porpoise surveys. It was suggested that a double platform setup similar to the SNESSA survey could also be used. There were also suggestions to investigate the possibility to employ an aerial survey.

Lydersen mentioned that a harbour porpoise has been photographed in Svalbard by the Monaco Glacier in 2006. The geographical configuration of the coast would have forced this animal to pass north of 80°N, thus giving it the northernmost record for a harbour porpoise. Occurrence of a harbour porpoise at this site was first recorded in 2004, then in association with a group of belugas.

With regards to conducting an assessment which might include distribution and abundance, stock identity, biological parameters, ecological interaction, pollutants, removals and sustainability of removals (NAMMCO 7), estimates of abundance and removals are still needed in all areas. The T-NASS survey will provide an estimate for the coastal area around Iceland, and maybe Greenland but will not do so for other areas.

10. BY-CATCH OF MARINE MAMMALS

Ólafsdóttir presented the report of the Working Group on By-Catch (BC WG) under the Management Committee in 2007. She reminded the Scientific Committee about the recommendations made: 1. Review by-catch monitoring systems used in other jurisdictions and various types of fisheries, and provide advice on the most effective systems in terms of delivering accurate and precise estimates of by-catch at reasonable cost; 2. Review information on fisheries and by-catch in NAMMCO member countries to determine which fisheries are likely to catch the greatest number of marine mammals and/or negatively affect the conservation status of marine mammal stocks; 3. Provide recommendations specific to country and fishery for monitoring by- catch in NAMMCO member countries; 4. On an ongoing basis, review the by-catch monitoring programmes in place in member countries and provide advice on how they can be improved.

10.1 Update on monitoring progress 10.1.1 Iceland No progress on by-catch monitoring was reported for Iceland since the last meeting of the BC WG.

10.1.2 Norway Haug presented SC/15/16 which described a system for monitoring by-catches of marine mammals in Norwegian coastal and inshore waters. A number of coastal fishing vessels had been contracted to provide very detailed information on their 170

NAMMCO Annual Report 2007 - 2008 fishing effort, catches and by-catches including incidental catches of seabirds and marine mammals. The skippers were offered economic compensation for providing the required information. The financial compensation in combination with the selection procedure and a continuous personal dialogue with the skippers contribute to the reliability of the reported information. A total of 18 vessels had been contracted by the end of 2005, two vessels in each of 9 fishery statistics areas covering the entire Norwegian coast. The data obtained so far indicates that this is a promising method for monitoring by-catches and estimating total removals of marine mammals by commercial coastal fisheries. Haug also presented SC/15/17 which reported the number of mammals taken as by-catch by the 18 vessels in 2006: 149 harbour porpoises, 27 harbour seals, 10 grey seals and 8 harp seals. A method to be used to extrapolate by-catches from observed fishing effort (on the 18 vessels) to total fishing effort (the entire Norwegian coastal fleet) has been developed and is currently being validated.

10.1.3 Faroes No progress has been made in the Faroes on this subject.

10.1.4 Greenland There is no separate reporting of by-catch for either small cetaceans or seals. By- catches are expected to be reported with direct catches, although this is not mandatory.

10.2 New request and future work The Committee recommends the organization of a workshop to review the use and applicability of the by-catch monitoring systems in use in different organizations. It was suggested to seek contact with other organizations dealing with by-catch monitoring in view of initiating collaboration on this matter. Ólafsdóttir was designated chair for the Working Group for this workshop with the support and help from the NAMMCO Secretariat.

The following documents will be used to set priorities in the assessment of by-catch among the different species and fisheries. • NAMMCO 15/MC/BC/6 - Bjørge, A., Ynnesdal, H. and Hartvedt, S. Spatial structure of Norwegian fisheries and the associated risk for by-catches of marine mammals. • NAMMCO 15/MC/BC/7 - Bjørge, A., Borge, A. and Kleven, S.

Report of the Scientific Committee

11. PUBLICATIONS

11.1 NAMMCO Scientific Publications (NSP) 11.1.1 Update on the grey seal volume and NASS volume Grey Seals volume Acquarone reported that the NSP 6, Grey Seals in the North Atlantic and the Baltic was published and distributed in 2007. This volume has had a considerable success as demonstrated by the interest it has attracted and sales at the SMM Biennial Conference 2007 and at the ECS Annual Conference 2008.

Mention of this volume has been made on the MARMAM discussion list both as a volume and as individual articles.

A copy of the volume has been sent to the Editors of Marine Mammal Science with the purpose of reviewing.

NASS volume Acquarone reported that the articles for inclusion in the volume have all been reviewed and that all but two are ready for publication.

Pike will shortly write the Introduction and together with Lockyer will begin the final editing of the volume.

The Committee recognizes the need to complete the process and recommends to proceed speedily with the publication process.

11.1.2 Update on the harbour seal volume Desportes reported that the Editors (Desportes, Bjørge, Rosing-Asvid and Waring) have received responses from thirty groups and that therefore it is foreseeable that a similar number of papers will be submitted. Tentative titles and volume thematic subdivisions are listed in document SC/15/13. The deadline for submission has been set to 30 June 2008 and publication is expected in the first quarter of 2009.

It was noted that the editing responsibility, including contact with reviewers, has been divided among the editors.

11.2 Other publications T-NASS: Desportes reported that T-NASS participants have expressed interest in publishing the results from the 2007 surveys in a common platform. She mentioned that Greg Donovan (IWC) had offered to dedicate an issue of the Journal of Cetacean Research and Management (JCRM) to this purpose. Alternatively the T-NASS results could be submitted simultaneously to another journal (e.g. Deep Sea Research).

The Committee recommended that the Secretariat investigates the possibility of a common IWC- NAMMCO volume of JCRM and encouraged the authors to strive to publish all the T-NASS-related results in the same publication. 172

NAMMCO Annual Report 2007 - 2008

The Committee recommended looking into the possibility of making the NAMMCO Publications Series available online.

12. BUDGET

Desportes presented the budget and accounts which detailed the costs of all the Scientific Committee activities throughout 2007. These costs included special costs related to activities up to, during and after the T-NASS surveys. Acquarone proceeded to introduce the budget for the year 2008. As for the previous year, the budget included specific travel funding provided to experts, meeting costs and work contracts and T-NASS-related activities. All costs were within budget, and both the 2007 budget and accounting and the 2008 budget were approved as presented.

13. FUTURE WORK PLANS

13.1 Scientific Committee It was decided that the next meeting of the Committee will be held in the Faroes at a place yet to be decided. The time for the meeting will be decided according to the timing of the next Council Meeting. Two alternative dates have been suggested: 1. Late April-early May 2009 if the Council decides to meet in the fall 2009 2. Middle-late November 2009 if the Council decides to meet in the spring 2010

13.2 Working groups The following working groups will hold meetings during 2008/2009: • Monitoring of pilot whales summer 20082 • Abundance Estimates before the Assessment of whales • Assessment of fin whales before spring 2009 (before the next SC meeting) • Assessment of minke whales 2008-2009 • Assessment of humpback/sei whales The first step together with Assessment of fin whales • Marine Mammals and Fisheries Interactions between October 2008 and March 2009 • Beluga and narwhal before March 2009 • By-catch monitoring first half of 2009 • Walruses 2008-2009

Additional meetings may be held, depending on requests received from the Council.

13.3 Other matters

2 Meeting held in Copenhagen, July 2008. The Report is NAMMCO/17/5 Addendum. 173

Report of the Scientific Committee

The Secretariat took note of these scheduled meetings and also noted that there might be additional requests from the Council in 2008. These will be reflected in the preparation of the 2009 budget.

14. ANY OTHER BUSINESS

14.1 IWC Workshop on Maximum Sustainable Yield Rate Walløe attended this meeting in Seattle (WA, USA) in November 2007 on behalf of the Committee. No observer report has been provided to this meeting.

14.2 Marine Mammal Oil An “Expert meeting on potential positive health effects of consuming whale and seal oil” was held in Copenhagen on 3 October 2007 hosted by NAMMCO. Acquarone reported that this meeting brought together a wide variety of stakeholders from research groups on human health, representatives of marine mammal hunter associations, producers of marine oils, politicians and managers. It was noted that positive effects of consuming marine mammal oils especially on joint pain and irritable bowel disease are evident and lasting and that these are maximised when the oil is cold-pressed and consumed mixed with high quality fish or olive oil.

14.3 Seals and Society Meeting Acquarone reported about the “Seals and Society – how to manage resources and interactions in the Baltic Sea and North Atlantic” meeting in Vaasa (Finland) 16-18 October 2007. He mentioned that this conference was organized on the occasion of the Finnish presidency of the Nordic Council of Ministers. The aim of the conference was to generate solutions towards implementing sustainable management strategies for seal stocks and interactions between seals and society. Furthermore, the conference aimed at facilitating the exchange of experiences encountered in the Baltic Sea and North Atlantic and at identifying strategies and best practices for the implementation of seal stock management and conservation. The NAMMCO Chair Kate Sanderson chaired sessions of the conference and the NAMMCO Secretariat and several members of the Scientific and Management Committees attended the meeting and actively participated in the discussion. Material on the conference is available on the web page www.seal2007vaasa.fi

14.4 Bio-logging Conference Lydersen mentioned that Barbara Block and Dan Costa, principal investigators of Tagging of Pacific Predators (www.topp.org), a Census of Marine Life project, are hosting the Third International Bio-logging Science Symposium. The gathering will take place from September 1-5, 2008 at the Asilomar Conference Grounds in Pacific Grove, California. Lydersen pointed out that this conference has high interest for people involved in tagging of marine mammals and that a special volume including the proceedings of the meeting will be published.

14.5 Election of Officers The period of office for the current Chair and Vice-Chair is due to expire at the Council meeting in September 2008 after the report of the SC has been presented, 174

NAMMCO Annual Report 2007 - 2008 according to current Rules of Procedure (ROP) for the SC. It had been discussed within the committee whether or not a 3-yr term of office would not be more practicable for both the chairpersons and the Secretariat to enable better continuity of work. The present and past chairs noted that it took about a year just to become familiar with NAMMCO procedures. In the past, several Chairs have extended their terms of office for different reasons.

For practical reasons it was noted by the Secretariat that it would benefit from an experienced Chair while the new Scientific Secretary learns the tools of the trade.

The SC were thus in favour of proposing a change to the SC ROP to extend the terms of office to 3 yr, and recommended a standard 3-yr term of office as Chair and Vice- Chair. A proposal will put to Council (as per NAMMCO SC ROP Item VII).

The SC meanwhile, re-elected Desportes as Chair and Lars Witting as Vice-Chair. Desportes agreed to continue in office for a full 3-yr term (or through the next SC meeting and subsequent Council meeting) before transferring over to the current Vice- Chair, Witting. The SC members present were unanimous in agreement to this, and thanked her for her continued efforts.

15. MEETING CLOSURE

15.1 Acceptance of report A draft version of the Report, containing all items that were agreed upon, was accepted on 14 April 2008. The final version was accepted by correspondence on 1 June 2008.

15.2 Closing remarks The Chair noted that many studies which were referred to during the meeting, presented or commented upon, were often not tabled at the meeting, including papers which should be presented at the IWC SC shortly after. She thought this was a shame, since their presentations would increase information sharing within the committee. She asked therefore if people would agree to present the relevant documents as ‘other publications’ – already published articles can also be presented as such. The committee agreed to do so for this and the meetings to come.

The Chair thanked Acquarone for his diligent rapporteuring, and the Secretariat for organizing the meeting and for general support. The SC in turn thanked Desportes for her able chairing of the meeting. The meeting was then declared closed.

Report of the Planning Committee T-NASS WG III

ANNEX 1.1 NAMMCO PLANNING COMMITTEE ON THE TRANS NORTH ATLANTIC SIGHTINGS SURVEY (T-NASS) WORKING GROUP III St. Andrews, UK, 30 March – 1 April 2007

PLENARY SESSION

1. CHAIRMAN’S WELCOME AND OPENING REMARKS

The Chairman, Geneviève Desportes, welcomed the Delegates (see Section 5) to the third planning meeting for the Trans North Atlantic Sightings Survey (T-NASS), kindly hosted by Phil Hammond at the Sea Mammal Research Unit (SMRU). She briefly reminded the convened Delegates of the unprecedented uniqueness, value and synoptic character of T-NASS. A listing of the agreements from the two previous meetings and a reminder of the time constraints ahead followed. The Chairman underlined that the Delegates have agreed on strong coordination and invited them to briefly introduce themselves to the new members. Finally the Chairman pointed out that by end of the meeting a draft instead of a full meeting report would be produced and that the full report will be submitted to the Delegates for approval by e-mail by the end of April.

2. ADOPTION OF THE AGENDA

The draft Agenda circulated before the meeting (Appendix 1) was adopted unanimously without modifications.

3. APPOINTMENT OF RAPPORTEURS

The NAMMCO Outgoing Scientific Secretary (Daniel Pike) and Appointee Scientific Secretary (Mario Acquarone) were designated as general rapporteurs. Specifically, Greg Donovan volunteered for reporting on the Aerial Surveys Working-Group and Mario Acquarone for reporting on the Shipboard Surveys Working-Group.

4. STATUS

At this point the Chairman invited the Delegates to present the status of the project in their respective areas.

4.1 Resources per area Faroes One vessel able to carry two platforms has been approached, but the charter contract has not been signed yet.

Iceland A formal request procedure had to be followed, only 2 offers for vessels had been received, but none was good enough and both were refused. The Redfish Survey 186

NAMMCO Annual Report 2007 - 2008 vessel is ready and available. Other possibilities are being investigated to obtain vessels for the main T-NASS and there is confidence in finding other vessels in a matter of weeks. A Partenavia Observer aircraft equipped with bubble windows, and possibly even with photo equipment, has been secured for charter between 20 June- 21 July. This should amount to approximately 100 hr flying-time.

UK-CODA The tender process for the ship charters will be completed in May and the contacts will be passed on to Iceland. There may be 2 Faroese platforms in sight.

Greenland The vessel available for the Shipboard Survey belongs to the Danish Navy. The Navy has specified that they would have to respond to any emergency during the survey period, which could mean an interruption of the survey work. The ship will be made available in Ilulissat and has to return to Narsarsuaq at the end. This means that the surveying work will have to follow a North to South course. Due to military obligations the vessel will have to stay in Greenlandic waters. The Canadian part of South Baffin Bay and Davis Strait will have to be surveyed otherwise. The Greenland Delegate remarked that it is a small round-bottom vessel which may be very uncomfortable for the observers and have practical stability problems. A contract with Air Greenland has been signed for the charter of a Twin Otter aircraft with bubble windows for a series of surveys beginning in mid-August.

Canada This survey will be conducted by the Federal Department of Fisheries and Oceans (DFO). Funding for the the Newfoundland-Labrador strata has been secured, and it will be surveyed using a charter Twin Otter aircraft. $100K CAN funding for the Gulf area survey component has been secured, and there is a an assurance that funds to conduct the full Gulf survey (an additional $50K CAN) will be found. As far as the Scotian shelf area is concerned there is no funding yet, but there is reasonable certainty that the area will be surveyed. The intent is to begin the Canadian survey in mid July in the northern Labrador area, and continue southwards in what is presumed to be the opposite direction to the annual migration patterns of several large whale species expected in the survey area. The Gulf survey will commence in July, with the likely survey platform being a Cessna 337 Super Skymaster (as has been done in previous surveys here). If funding is available, the Twin Otter team will continue flying transects along the Scotian Shelf in August at a time to correspond with the American effort to the south. The survey transects will be designed for all strata in the Canadian survey areas (with the assistance of D. Pike), and logistical planning is underway to begin the surveys later in the summer. All necessary equipment is in place to carry out the visual surveys. No vessel-based observations are planned. Lawson has requested several days flying time on a Canadian military aircraft, the Arcturus, whose primary mission is to monitor fisheries within NAFO areas. The aircraft has long range (up to 17 hours duration), is extremely well-equipped with navigation, observation and acoustic recording equipment. However this aircraft has a minimum manoeuvring airspeed of 170 knots which may be faster than practical for a marine mammal survey. The Canadians are hoping to assess the efficacy of this 187

Report of the Planning Committee T-NASS WG III platform during several trial flights in the Davis Strait between southern Baffin Island and Greenland, and off the Flemish Cap of eastern Newfoundland. The hope is that Jack Lawson will employ this platform in August.

4.2 General funding available NAMMCO council has decided to allocate most of the 2007 NAMMCO Scientific Committee budget plus a special allocation of 150,000 NOK to T-NASS and T-NASS extension.

The Nordic Council of Ministers had allocated to T-NASS 128,000 DKK. There has been no success in finding additional funding. The latest rejection came from the Danish “A.P. Møller og Hustru Chastine McKinney Møllers Fond til amene Formal”. The rest of the funding needed for equipment, salaries etc. will have to be sought from other sources.

NAMMCO will address applications for sponsorships in the order of magnitude of ca 20-50,000 DKK to small companies in the different T-NASS countries, if the necessary information is forwarded by these countries. An application of this kind has already been sent out in Iceland and a response is expected shortly. (for information, the answer given after the end of the meeting was positive and ca 300 kDKK were secured for the Icelandic part of the acoustic survey)

There is some uncertainty on how to finance the salaries of the observers on the Greenlandic surveys.

Some equipment could be loaned or rented. Paul Thompson makes available up to two hydrophones, even though one has to undergo repair. However they are different to the ones used in SCANS II and CODA and special analysis would be necessary, which is not optimal. Canada later agreed to loan two pairs of “Big Eye” binoculars and stands to other partners, as well as two sea surface temperature measurement systems for the aerial survey teams.

The Chairman urged all the Delegates check and report to the Secretariat the amount of funding already secured and what is needed for the ordering of necessary equipment (e.g. hydrophones for acoustic monitoring and standard material for opportunistic surveys).

4.3 Coordination with opportunistic surveys Redfish Survey in the Irminger Sea All vessels will embark observers and all have the capability of towing hydrophones. The German vessel will be leaving Bremerhaven 14 June and is planned to be back by 14 July. NAMMCO will provide two whale observers for this ship. The Russian vessel Smolensk will have one NAMMCO observer and one Russian observer onboard. It will be preferable to pick up the NAMMCO observer in Reykjavik for bureaucratic and practical reasons. Smolensk will leave Murmansk between 5-10 June and will have to be back in Murmansk at the end of July – for approximately 50 cruise 188

NAMMCO Annual Report 2007 - 2008 days. Smolensk will be calling in Reykjavik 22-24 June/9-10 July. In the Norwegian Sea, on its way to the Irminger Sea it will perform other Oceanographic and Ichthyology work within the framework of the INFERNO cooperation between Russia and Norway.

Pelagic survey in the Norwegian Sea: Norway Two vessels have been charted for three weeks between 15 July and 7 August to perform an adaptive survey in a large area of the Norwegian Sea. One vessel will have BBC people to film blue whales in the waters around Jan Mayen. There will be two T- NASS observers on each vessel. IMR will hire the observers directly and NAMMCO will provide the equipment and the procedure.

4.4 SCANS II Data analysis problems, avoidable with a better data collection. A list of comments based on her experience with SCANS II data was provided by Louise Burt (Appendix 2).

5. GENERAL STRATEGY FOR COVERAGE

The general strategy for coverage was discussed in the following points.

5.1 Survey design in Distance Presentation by Len Thomas based on the distributed paper “Designing line transect surveys for complex survey regions” J.Cetacean Res.Manage. An interesting and useful presentation was held by Len Thomas on the use of the programme Distance and on Survey Design. Among the points he made was that effort should be distributed equally over the survey area unless there is prior information that warrants stratification. The general coverage probability can be estimated if the coverage probability for all sub-areas is known. However this calculation is not (yet) implemented in Distance.

As far as the design of transects, it is clear that zigzag minimizes lost effort for transport from one transect to the next and that it is best to get many reasonably short transect samplers rather than few long ones. In big areas it is possible and advisable to divide the stratum lengthwise so that the number of lines, and thus samples, will be increased. This presents the advantage that the lines can be cruised in both directions In general an equal spaced zigzag has proven best for non rectangular areas.

In case the shape of the strata is very complex one can improve and ease the design by cutting the complex shape into sub-areas while retaining spacing. One will typically then generate several survey simulations for the same area. The subdivision in sub- areas presents the drawback that transects in adjoining sub-areas do not necessarily join up.

Complex coastlines such as fjord areas will necessarily present serious edge effects that are large proportional to the survey area. In this case it is generally more correct

189

Report of the Planning Committee T-NASS WG III to orient the transect lines perpendicular to long axis but shallow angle zigzags could also be used.

5.2 Considering the combination of both dedicated surveys and opportunistic surveys: do we want overlapping areas or can we rely on the opportunistic data? The value of simple distribution data and on the importance of maximizing coverage was generally agreed upon. It was pointed out by some Delegates that T-NASS should strive as far as possible to provide an estimate compatible with IWC standards and this might mean that the opportunistic surveys could not be included for a density estimate within the IWC framework.

In conclusion all the important areas for which it is necessary to obtain a reliable population abundance estimate of target species have to be covered by a dedicated Survey.

6. SCANS II SHIPBOARD METHODOLOGIES: VISUAL AND ACOUSTIC (Presentation by Doug Gillespie and Rene Swift)

SCANS II shipboard methodologies were presented by Doug and Rene in their lab.

6.1 Presentation of the shipboard visual and acoustic methodologies and protocols This point was treated together with the next in the laboratory with the equipment at hand.

6.2 Presentation of shipboard visual equipment and acoustic equipment See above 6.1.

SUB-COMMITTEES

7A. SURVEY DESIGN

Present at this Sub-Committee were: Pike (chair), Acquarone (rapporteur), Desportes, Donovan, Golyak, Gunnlaugsson, Hammond, Lawson, Mikkelsen, Simon, Vikingsson, Zabavnikov and Øien. The Sub-Committee Chair Daniel Pike reminded the Delegates that the aim of the Sub-Committee is to help and assist with designing the following components of the survey (from West to East): • Canadian aerial surveys, including Twin Otter, Skymaster, and Arcturus components; • West Greenland Ship Survey; • Iceland ship survey, taking into account existing redfish design; • Iceland aerial survey, secondary inshore strata; • Faeroes ship survey.

The task can be divided into the following 3 components: 190

NAMMCO Annual Report 2007 - 2008

1) Establishing boundaries of survey areas; 2) Stratification and Effort allocation; 3) Transect design.

The first two points should be agreed upon as a group and the transect design will be left for a specialized working group.

In general the procedure should be: 1) Establishment of boundaries of national survey areas, with regard to known boundaries of other surveys, available effort and species distributions. 2) Stratification within areas, based mainly on species distributions. 3) Assignment of effort to these strata, based on expected density of target species.

For the moment the Sub-Committee should concentrate its work on procedural points 1) and 2).

7A.1 Survey boundaries (in coordination with CODA, SNESSA and opportunistic surveys) Because of the synoptic aspect of T-NASS it is necessary to examine the different areas each for itself and as a whole.

Norway It has been decided to give highest priority to survey the Eastern Barents area if the permission from Russia can be obtained. A final decision on the permission to enter Russian waters is not far away. In the best of cases one vessel will survey the Eastern Barents Sea and the other will concentrate on VHF tagging and looking for blue whales with the BBC. A “Plan B” for Norway in case permission from Russia is refused could be to add to survey blocks BJ, NØN, SV and SVI.

The southernmost boundary of the Norwegian survey will be 74°N which will coincide with the northernmost extent of the Icelandic survey.

The committee regretted that very little, if any, consideration was given to T-NASS needs in the Norwegian decision.

Greenland ship The ship survey should extend to the Greenland-Canada mid-water line. Greenland will have: • a wide northern area out to 58°W from just south of Disko and down to the latitude of Nuuk • a narrow southern area a little bit beyond the shelf extending a little the previous surveys. It was agreed that these are fin whale areas and that we have to allocate equal sighting probability for the two strata.

191

Report of the Planning Committee T-NASS WG III

Canada Survey transects will extend from the coastlines out to slightly past the shelf break. The southeastern part of the Newfoundland area will be covered as much as possible but will have to be truncated at its outer margin because of technical considerations (Twin Otter range). The proposal for the Arcturus will be to survey across the southern Davis Strait (and perhaps the southwestern tip of Greenland), and off the Flemish Cap of S.E. Newfoundland over a period of 2-3 days.

Faroes The area to be covered by the Faeroese will be contained between the Icelandic areas in the West, the Norwegian area in the North and the CODA boundary in the East. It was agreed to use a southern boundary at 52° N. Available effort is known.

Iceland ship It was agreed to use a southern boundary at 52°N extending as far east as the CODA boundary and that it was not necessary to re-cover the opportunistic areas unless there is a very high density of animals. It was also agreed to delimit the north block I at 74°N and 4°W. The 74°N is because of the “Plan B” Norwegian survey which is planned to extend down to that latitude.

The Western boundary of the Icelandic Redfish vessel will be Cap Farvel so it meets with the Greenlandic ship survey. Available effort is known.

The two blocks south and east of Iceland will be covered by the Icelandic and Faroese vessels respectively.

Iceland aerial secondary strata These will be done on days when it is impossible to fly offshore. It should be considered a pilot project and should cover several fjords that are not well covered in the main survey by establishing transects in them. There is little information available on the distribution of harbour porpoises in the area. Available effort is not known and these will be done opportunistically.

CODA’s bight, south of Ireland, will be filled by France. The North and northwest boundaries are flexible. CODA will join to the SCANS II area, and the Faroese T- NASS block and CODA will join.

Additionally Stratification of the new areas will be executed in an appropriate manner to reduce effort in areas of lesser priority because of the coverage by opportunistic surveys.

A small block “opportunistic stratum” will be drawn around the Charlie Gibbs fracture zone to be surveyed if there is time (down to 50°N). This can be done by the Icelandic or the Faroese vessels or both.

192

NAMMCO Annual Report 2007 - 2008

7A.2 Stratification Canada • Newfoundland: on the basis of fin and blue whale distribution there will be 3 strata, North, South and Central with most effort allocated to Central. Attention should be paid also to minke whale distribution, especially Davis Strait sightings. • Gulf: stratification is complete and based on previous DFO aerial surveys by Kingsley. • Scotian Shelf: not much basis for stratification, maybe East - West blocks but maybe not.

Greenland • It was suggested as a possibility to divide the area from Nuuk south to Kap Farvel, into an inshore and offshore stratum. The inshore stratum should have most effort and should extend to just beyond shelf break, maybe 10 km or so. • The coverage by the Arcturus might depend on realized effort in offshore stratum.

Iceland • Redfish blocks: it was suggested to divide the area into 3 blocks: North, West and South, with higher effort in North and West blocks. • Otherwise it should be similar to 2001 scheme. • Eastward extent depends on the extent of the Norwegian survey. • It my be useful to consider a southward extension west of Coda and east to Redfish extension blocks, as this is an important area for pilot whales and other species such as beaked whales.

Faroes • Similar to 2001 but it depends on where the Norwegian effort is allocated.

7A.3 Effort allocation by stratum (and estimation of realizable effort) The northern blocks These will be divided in two blocks by a vertical line and the two resulting blocks will have equal coverage.

Redfish blocks • A Western stratum that as far as possible has equal area coverage. • A Northern area will be an extension of the Northern block (already decided). • A Western boundary to the south-central block will be moved slightly to the west to include the Mid-Atlantic ridge. But pay attention: “the world is big down there” (Phil Hammond).

Greenland Equal coverage will be attempted as a starting point (equal-space zigzag).

193

Report of the Planning Committee T-NASS WG III

Canada The Newfoundland and Labrador (NL) survey component will comprise 3 strata, with most effort allocated to the eastern stratum that will extend from southern Labrador to the southeastern coast of the island: NL Labrador Stratum (69,540 n.mi2, 20% of NL effort); NL Eastern Stratum (81,360 n.mi2, 40% of NL effort); NL Southern Stratum (62,660 n.mi2, 40% of NL effort). • Scotian Shelf: no stratification is planned, assuming equal probability (56,810 n.mi2). • Gulf: stratification from previous DFO surveys, assuming equal probability (66,930 n.mi2). • An equal-spaced zigzag pattern will be used in the Newfoundland and Labrador, and the Scotian Shelf strata. East-west and north-south transects will be employed in the Gulf strata. • The opportunistic Arcturus trial will cover survey areas as determined above.

Norway The Norwegian vessels will sail from Kirkenes. Time allocation for T-NASS is 2-3 weeks. • It is recommended that Norway’s survey join up appropriately at 74°N with the Icelandic block up to the ice edge, and that the transit area from Kirkenes be included. • The committee appealed to Norway to use as much effort as they have available for a direct participation in the T-NASS effort.

7A.4 Transect design See 7A.2 and 7A.3 above.

7A.5 Other (e.g. coastal harbour porpoise strata in Iceland) See 7A.1 above.

7A.6 Rules for adaptation (i.e. changing the design underway) It was firmly underlined that the tracks must not be redesigned underway so as not to jeopardize the validity of the estimate. However a redistribution of vessels is allowed.

Daniel Pike will provide the track design. He will contact the delegates for the details needed.

Geneviève reminded that, in the allocation of effort, training time on land and at sea has to be taken into consideration as it takes time to get used to the new technology and distance estimation.

It was agreed that at least 2 harbour days be used for equipment setup and use training and at least one sea day must be allocated to training in effort conditions and that training continues further until satisfactory results be obtained.

7B. SHIPBOARD PROTOCOLS

Present at this Sub-Committee were: Acquarone (rapporteur), Desportes (chair), Golyak, Gunnlaugsson, Hammond, Mikkelsen, Simon, Vikingsson and Øien.

The Chair (Desportes) reminded the group that the aim was not to finish the session with a written protocol, but it was important to reach an agreement on all the points that a protocol is composed of.

7B.1 Review of protocol for dedicated surveys with 8 observers and 2 independent platforms 7B.1.1 Survey modes Iceland - Faroes - 4 vessels with 2 independent platforms which will follow the BT methodology, as agreed last meeting.

The higher-tracker platform will concentrate on far sightings and the lower-primary platform will concentrate on nearer sightings within 500 m from the trackline.

Tracking - it was agreed to track everything except sperm whales, and to assume minke whales as very high priority (i.e. always track even if you were tracking something else). It is important to be sure to track small cetaceans (species identification and school size).

It was agreed to track up to Sea State Beaufort 4 included, with no reason for tracking in Beaufort > 5. When the conditions impose a stop in tracking, the platforms are combined as a single primary platform (the observers remain in place but work in the same way searching everywhere). A code should be inserted in the effort form for indicating which searching mode was used, i.e., the exact point when effort is shifted from two separate to one single (combined) platform should be recorded with certainty.

Note that when using the BT mode, it is important to keep the primary platform separate from the trackers, and to keep the same pairs of primary observers during the entire survey to minimize heterogeneity.

7B.1.2 Equipment It was agreed not to use “Big eyes” because of cost and difficulty in timely delivery, but to use medium and small binoculars. The medium binoculars will be attached to a monopod fixed to the deck at the bottom end.

The observers should be advised to have their own computer with them to speed up the data validation and control process.

It was agreed on a previous occasion to use the visual equipment developed for SCANS and the order was placed for four kits.

195

Report of the Planning Committee T-NASS WG III

7B.1.3 Survey procedures Shipboard T-NASS will generally follow the procedures developed for SCANS.

For technical positions it might not be advisable to have persons with low computer or English skills (e.g. whalers).

Observers on the primary platform should concentrate to look and search without using binoculars up to 500 m but all their sightings will be recorded even beyond that distance.

T-NASS will aim to avoid paper forms, but these should be available in case of catastrophic events or “learning challenged” observers.

Observers with 7x50 binoculars should search between +60°-60° and the observers with the medium eyes binoculars should search +40°-40°. Trackers platform observers will track until duplicates are established or the animal has passed abeam of the vessel. The two trackers will cooperate on tracking the same sighting. The Duplicate Identifier (DI) will act as observer when not assisting the duplicate. The DI will be using 7x50 reticules and will pass any sighting to the trackers. Closing mode for ID will only happen when the sighting is abeam and closer than 1.5 nm.

7B.1.4 Sighting protocol No need for discussion at this meeting.

7B.1.5 Data collection procedures No need for discussion at this meeting.

7B.1.6 Calibration experiments (distance and angle experiment) No need for discussion at this meeting.

7B.1.7 Data calibration No need for discussion at this meeting.

7B.1.8 Cruise leader and observer training Iceland Training will be done by Desportes and Jacobsen (a tracker from SCANS II) first on land, then at sea and will possibly be held in common for all the vessels. Faroes Training will be done by Mikkelsen and Hansen (a tracker from SCANS II) first on land, then at sea.

7B.2 Review of protocol for the Greenlandic vessel with a single platform and 4 observers Differing combinations of observers were suggested. One suggestion was to have at any time 2 observers on duty and 2 resting. The other suggestion was to have 3 196

NAMMCO Annual Report 2007 - 2008 observers working simultaneously and 1 rotating. It was recommended that if possible, 3 observers worked at the same time. If weather permitted long working days in a row, then two observers would work at any time. It was underlined that it is important to have best quality effort rather than effort over longer periods with doubtful quality (observers give better data working in pairs and need to rest). A minimum of 6 hrs rest per night was recommended.

Single Platform Surveys will be in Passing Mode (Closing allowed for species ID, when sighting passed abeam and not further than 1.5 nm)

The recommendation of the WG is to place 2 persons on the lowest platform. They should concentrate on searching with their naked eyes +90°-10° and reciprocal. Another observer should be placed in the crows’ nest to keep a look out ahead with binoculars at +30°-30°. Binoculars (reticules) should in general be used only when looking at +30°-30° ahead.

The use of 3 observers is highly recommended and they have to be able to communicate easily with each other to avoid double sightings (via radio-link?). In case money is an issue then the observer in the barrel can communicate with the others through a radio-link. Data can be recorded on a single computer or on paper.

The ship will be in Nuuk in April and only at that time will it be clear if there is space in the crow’s nest.

For the training of the observers, days must be allocated and eventually the cruise leader could be participating in the Icelandic training if useful (noting the difference in the equipment).

7B.3 Review of protocol for opportunistic surveys 7B.3.1 With 2 observers: Redfish (Russian and German) and pelagic survey The ships will operate in passing mode with no closing. It was recommended that the two observers work and rest together at the same time.

To give an idea of the working hours it was pointed out that in the Norwegian Sea the rest time is usually 6 hrs. The Icelandic ships will trawl approximately 4 hrs three times a day when the speed will be at most 2 kn. This is an obvious time for the observers to rest. The Russian ship will trawl shallower with a corresponding reduction in trawl time.

The observers search with naked eyes from +90°-10° and reciprocal and that they use a recording system similar to the Greenlandic vessel. For large angles (60°-90° almost abeam) they should concentrate the search close to the vessel. Binoculars are only to be used for species ID and determination of school size.

7B.3.2 With one observer: MAR-ECO The procedure is the same as those for the Redfish vessels. The recording system will also be the same as the Greenlandic vessel. 197

Report of the Planning Committee T-NASS WG III

Single observers should look symmetrically around the trackline ahead, but concentrate on the trackline

7B.3.3 Training of ‘opportunistic’ observers If possible, at the discretion and with the collaboration of the ship’s captain, these observers could be trained in distance estimation using a buoy-radar reflector system.

7B.4 Ice edge protocol In case of ice encounter the vessels should follow the SOWER protocol (IWC).

7B.5 Group size estimation for pilot whales and dolphins In SCANS II Guidelines for Observers p.11 there are instructions for this situation. In those instructions it was indicated preferable to cut large groups in subunits and to record them separately. It is important to note as much as possible of the details of each sighting. For large and very “messy” groups, use common sense.

For all vessels, it is important to ensure that the data are entered/validated as soon as possible (e.g. every evening).

7C. AERIAL SURVEY PROTOCOL

Present at this Sub-Committee were: Donovan (Chair/Rapporteur), Lawson, Pike, Simon and Zabanikov.

7C.1 Review of protocol for dedicated surveys with 4 observers and 2 independent platforms (Iceland and Greenland – September survey) 7C.1.1 Survey mode It was agreed that for fin and minke whales, cue counting would be the primary method, with blow being the cue for fin whales and dive the cue for minke whales. In practice, the data collected will be in a manner to allow either cue counting or line transect analyses as appropriate.

The surveys will be carried out in independent mode (at least one-way audio/visual isolation) to the extent possible. The pilot will not be considered as an observer but should quietly inform the cruise leader if making a sighting. Ideally, there will be an intercom system such that each observer has one way communication with the cruise leader during survey mode. For safety reasons, the pilot will need to be able to override the system. Further details can be found in the protocol document.

It is extremely important to ensure that the data are entered/validated as soon as possible (e.g. every evening). Appropriate software to allow the cruise leader to examine the data is essential to allow problems in collection to be identified as soon as possible. If necessary, an additional person should be used to ensure that the data entry entry/validation is kept up to date.

198

NAMMCO Annual Report 2007 - 2008

7C.1.2 Equipment The Icelandic aerial survey will use the usual (serviced and checked) equipment for recording the necessary data for sightings (Icelanders to clarify the potential copyright issues around use of the Hval programme).

Jack Lawson has kindly offered to lend one Sea Surface Temperature (SST) sensor. It is recommended that this be used on both the Icelandic (July) and the Greenlandic (September) surveys provided this meets air safety approval for the planes. He will send the system to Iceland and Greenland as soon as possible.

There may be video/still photography capabilities on one or both surveys.

7C.1.3 Survey procedures Survey speed Aim for as slow as possible (around 100 knots) depending on stall speed.

Survey height This depends on the primary target species. For the Icelandic survey, the altitude will be 600 feet as some priority is being given to harbour porpoises. In Greenland, it may be 750 feet (best for fin and minke whales) or lower if harbour porpoises are given some priority. There is no theoretical reason why different heights cannot be used depending on circumstances (e.g. low cloud, priority for harbour porpoises) provided altitude is accurately recorded (ideally a direct link to the altimeter) so that an appropriate effective searching width is estimated.

Survey conditions Surveys will be carried out in Beaufort Sea States of 3 or less along with other acceptable visibility conditions (e.g. wind, rain, fog etc). Further details can be found in the protocol document.

Large schools Procedure for closing on schools In general, surveys are effectively carried out in ‘passing mode’ – however there may be occasions when it is not possible to get a good enough estimate of schools size (or for certain small cetaceans, species and school size) for priority species. It is important to take distance and angle readings to the smallest discrete groups feasible while on track. Include comments where appropriate. In such circumstances, the cruise leader may decide to close with the school after abeam and then circle to get a good estimate of school size. For surveys where a large number of non-primary target dolphin schools are expected/found that might result in considerable ‘confirmation’ time and compromise the overall survey for primary species, it might be appropriate to determine a rule (either random or every xth sighting) to try to enable a correction factor to be determined (the school size estimates when abeam are compared with the ‘confirmed’ values). Further details can be found in the protocol document.

199

Report of the Planning Committee T-NASS WG III

Recording of additional data (other than usual effort and sightings data associated with cetacean surveys) It was agreed that recording of additional data should only be undertaken if the cruise leader was happy that this would not interfere with cetacean sightings and recording of primary data. Seal sightings will not be recorded in the Greenland survey. Marine debris, oil slicks may be recorded. SST data will automatically be recorded.

7C.1.4 Sighting protocol The past Greenlandic protocol (05tnass_5) will form the basis for the final protocol document. The final version, taking into account discussions at this meeting, will be developed by the working group within the next month.

7C.1.5 Observer training The importance of training was stressed. Considerable benefit can be obtained from training in the plane even when it is on the ground! Greg Donovan will rediscover the old cue-counting training program and circulate it to the working group. Priority should be given to giving the Greenland cruise leader training in Iceland.

7C.2 Review of protocol for dedicated surveys with multiple observers, one leader and one platform (Canada and SNESSA) 7C.2.1 Survey mode 7C.2.1.1 Survey mode (Canada) As in 7C.1.1. A line transect was suggested. It was agreed that the survey timing off coastal Canada (NL and Scotian Shelf components) would be designed to start in the north and move towards the south over time. This would reduce the chances of double-counting marine mammals if they are migrating from south to north, as it is assumed species such as fin and humpback whales are in this area. Similar transect timing issues will be addressed in the Gulf.

7C.2.1.2 Survey mode (SNESSA) Details on SNESSA were not available at the time of this meeting.

7C.2.2 Equipment Surveys in Canada and the SNESSA will be aerial-based visual surveys using multiple observers and dedicated data recorders. The SNESSA will also have a vessel-based component (see above).

7C.2.2.1 Equipment (Canada) The equipment used will ensure that the appropriate data can be collected, and in such as way as to accurately record the location and time of each sighting event. Therefore the data can be analyzed using cue counting or line-transect methods, depending on the species. This will be assured using a keypad triggering system for each observer that will be attached to the GPS-linked data recorder’s laptop computer. The computer will be running a modified version of NMFS’ VOR survey programme that can record

200

NAMMCO Annual Report 2007 - 2008 time, location, inclination, species ID, group size, sighting cue, weather, sighting conditions, and other notes. It is linked to a GPS system for location, and displays the course of the aircraft as well as the underlying transects for navigation checks.

Distances of the sighted animal(s) from the trackline will be determined be each observer using inclinometers.

7C2.2.2 Equipment (SNESSA) Information on SNESSA equipment and protocols were not available at the time of the meeting.

7C.2.3 Survey procedures Given the extensive survey coverage planned, the multi-species nature of the Canadian surveys, and the second rear observer station on the right side of the Otter, it is not feasible to use the ‘circle back’ procedure that has been used to estimate detection probabilities for harbour porpoises.

For the parts of the Canadian survey flown using the Twin Otter (NL and Scotian Shelf), independent data from front and rear observers at bubble windows on the right side of the aircraft (there is a single observer at the bubble window on the left side) will be compared to estimate detection probabilities (corrected for perception bias). While not ideal, it was agreed that it will also be possible to use correction factors obtained from the US surveys for harbour porpoises, which include a correction for availability bias derived from circle-back experiments. All three observers will be visually and aurally isolated from each other, passing data to the recorder using their keypads or headset microphones.

The Gulf surveys will be flown with a Cessna Skymaster, during which there will be two observers at bubble windows in the rear of the aircraft and a dedicated data recorder/navigator in the front right seat. As for the Twin Otter surveys, data will be recorded using the VOR programme on a GPS-linked laptop computer. Circle-back techniques are not planned to be used.

The Otter and Skymaster will be flown at 105 knots and 650 feet ASL (above sea level).

A proposal has been submitted that, if approved, will allow Canadian researchers to fly for several days in an Arcturus aircraft. This large, four-engine platform will be operated at 750 feet ASL and an airspeed of 170 knots. It is planned to have two independent teams of observers on the front and rear of the aircraft (6 people in total), collecting sightings data using the same protocol as for the Twin Otter. Circle-back techniques are not planned to be used. At this point it is unclear which survey pattern will be employed, but likely east-west oriented survey transects in two locations (described above).

201

Report of the Planning Committee T-NASS WG III

7C.2.4 Sighting protocol In both the Canadian and SNESSA aerial surveys, sightings data will be collected using Distance-based analyses of sightings locations relative to the survey trackline.

7C.2.5 Observer training In the NL Region observer training has occurred using dedicated flights with the Twin Otter and Skymaster platforms in the past several years. For the Otter, all survey equipment has been employed and tested. In the 2007 T-NASS it is not planned to conduct further training in advance of the survey.

PLENARY SESSION

8. REVIEW OF SURVEY DESIGN

It was agreed that transects should be based on the realizable effort plus a general bonus of ca 20% (Iceland and Faroes), where there was no other indication by the local coordinators. A parsimonious design will be used especially in the northern blocks assuming equal coverage in order to allow for flexibility to adapt the track design. This will allow the Icelanders to define the final survey tracks as late as possible in order to integrate the best and latest ice information available.

If an area is missed by one vessel, another may step in to cover the tracks missed. In general, how the “whale survey” time in the Redfish survey will be used must be defined on site. The cruise leader will have to decide on the base of local weather, previous coverage, and ship schedule (e.g. stop during the night).

It is very important to establish a viable working rhythm between the Redfish and Whale time and to follow it throughout the whole area.

9. REVIEW OF SHIPBOARD PROTOCOL

Seat and shelter for the observers should be provided.

10. REVIEW OF AERIAL SURVEY PROTOCOL

• Data for small areas. • Independent platforms in all areas. • Weather as normal, up to and including Beaufort Sea State 3. • Cameras may be present but only as ancillary. • Data entered and validated every day. • A ground person in Iceland to enter data. • SST on loan from Canada. • Standard methods. • Altitude 600 ft but record if different (650 feet in Canada in Otter and Skymaster, 750 feet in Arcturus).

202

NAMMCO Annual Report 2007 - 2008

• Mainly passing mode, with closing to confirm species identification and group size if necessary (abeam) but careful if many non-primary dolphins. • In Iceland closing may be carried out on a subset of dolphin schools to derive corrections for school size estimation. • Additional data will be collected if it does not interfere with the primary objectives. • Training important at all levels (even on the ground with a fishing rod). • Greenlandic cruise leader to be trained on Iceland. • US/Canada will not use cue counting. • Arcturus: importance to maintain two independent teams. • Icelandic plane: Experimental digital stills taking a strip of 200 m under the plane where each point twice right under the plane. • Greenland: Not sure yet but there will be either stills or digital.

11. OBSERVERS STATUS

Iceland Looking for at least one observer with acoustics background and/or a SCANS tracker.

Faroes Looking for 2 experienced and 2 additional observers (even 2 inexperienced), an experienced acousticians would be desirable.

Greenland Looking for one observer for plane and one for ship survey.

Norway Observers are being hired now, names to be sent to Nils Øien if any available.

12. COLLECTION OF ANCILLARY DATA

Jack Lawson agreed to provide temperature probes for the Icelandic and Greenland planes and the appropriate survey coordinators will ensure that the necessary installation approval from the authorities is obtained.

Vessels will regularly record water temperature and marine debris.

13. ACOUSTIC SURVEY

It was unclear at the time of this meeting whether there would be acoustic material available. For this reason there was no input about this on the protocol.

In any case, ships carrying acoustic recording equipment must be able to: • tow and hook up the material 203

Report of the Planning Committee T-NASS WG III

• have a shelter for the electronics • have a winch for hauling in the hydrophone.

In the Redfish Surveys the hydrophone will probably have to be hauled in while trawling. In the southern sector it would be desirable to have one hydrophone on the Faroese sector, so it could be used in an area adjacent to the CODA area.

Canada is investigating whether acoustic sono-buoys can be dropped from the Arcturus aircraft during the surveys. These will record marine mammal vocalizations, as well as ambient noise and anthropogenic sound sources.

14. BIOPSY AND TAGGING STUDIES

Biopsies and Photo-ID will have a very low priority but adequate equipment and instructions should be onboard.

15. BIRD SURVEY

It was unclear if it was possible to host bird observers on the Faroese and the two Icelandic vessels and there was certainly no room for them on the Redfish Survey, Greenlandic or Russian vessels.

Bird observers would have to bring their own platform and equipment.

Henrik Skov will be requested to contact the national contact persons and not expect an answer before at least a month.

16. CONTACT AND COORDINATION DURING MAIN SURVEY

As for previous surveys there should be contact for: • internal coordination • the “visual equipment”.

For any change in protocol or design the person responsible must contact the main advisor who will be equipped with (satellite)-phone and/or other permanent means of communication for the whole duration of T-NASS.

Genevieve Desportes will request technical support from the same team as CODA (Doug Gillespie: [email protected]).

Desportes, supported by Donovan, will be the general advisor for protocol or design change for the shipboard survey and Donovan for the aerial survey.

17. COORDINATION

Coordination matters were discussed under the following points.

204

NAMMCO Annual Report 2007 - 2008

17.1 IPY-ESSAR Contact has been kept with IPY-ESSAR contact person Ken Drinkwater who has received all information circulating internally in T-NASS. There was no further information on other activities in IPY-ESSAR. It looks as if there are not many coordination activities within it, just a lot of paperwork.

17.2 Other matters There should be coordination between the CODA - T-NASS (Faroese-Icelandic) vessels, especially those operating in adjacent areas. Contacts among the cruise leaders should be initiated shortly and Desportes will attend the CODA coordination meetings.

Permission to enter national waters has to be applied for and by the individual vessels. Usually this takes 3 months which means that applications should be sent as soon as possible. For entering into UK waters permission should state that T-NASS is in coordination with CODA which is financed by the UK government and endorsed by the IWC. T-NASS has also been endorsed by the IWC.

The IWC asks that a person trusted by the IWC Scientific Committee be designated to guarantee that IWC standards have been followed. Gísli Víkingsson will be the T- NASS contact person for the IWC.

18. T-NASS GENERAL ETHICS

T-NASS should be a reasonably environmentally responsible survey. To this end, waste should be collected entirely and brought back to shore even when international regulations would allow for disposal in the sea. This should be stated in the contract with the vessels. Furthermore, care should be taken that animals are not harassed in any way.

The Chairman suggested that T-NASS be made carbon-neutral. To this end some suggestions were made: • the Carbon Trust for planting a CO2 equivalent in trees • partial participation by taking care of travel for observers • minimization of oil consumption by good survey design.

In response to the general reaction, Hammond reminded them that EU-rules impose environmental considerations when choosing vessels. It was finally agreed that all cruise leaders and observers (all contracted personnel) be formally invited to contribute individually for carbon-neutral travel and that a pointer to a way to do so be included in the individual information material.

19. STRATEGY FOR DISSEMINATION TO THE WIDER PUBLIC AND PRESS

There is no money available in the T-NASS budget for the establishment and 205

Report of the Planning Committee T-NASS WG III maintenance of a website. The NAMMCO Secretariat has been appointed by the NAMMCO Council to be in charge of this task (creating the site, producing text, maintaining and updating the site). The site should ideally be a placed as a sub-section of the NAMMCO website and should be available at least in all NAMMCO languages. The update of the site should be performed at least at the beginning and at the end of the survey and at completion of the analysis. There should be links to the IWC, Canada, Russia, USA, as well as to CODA.

Multilingual Press Releases should be made available both at the beginning and the end of the survey.

NAMMCO and the different project participants should agree in advance on the content of both the website and the press releases.

20. TASKS TO BE COMPLETED

1) Data validation criteria 2) Protocols (to be ready by the end of April): a. Aerial (within a month) b. Ship (also as soon as possible, with priority to the single platform section. The latter has very high priority as it has to be sent to the translators) 3) Cruise reports guidelines and deadlines 4) Standard Contracts for Cruise Leaders and Observers 5) Survey Design 6) Request for permission to enter territorial waters to be submitted for individual vessels (immediately, as this can take several months to obtain).

21. DATA VALIDATION AND ANALYSIS

The Chairman reminded the Delegates that having good rules for the validation and quality insurance of the data is as important as good analysis. She therefore urged the Delegates to define common data validation criteria (e.g. using e-mail) very soon, and suggested starting by examining the CODA protocol as an example. It was common understanding that a uniform analysis strategy is paramount for maintaining the synoptic character of T-NASS.

To speed up the production of tangible results, data on the focal species should be assigned high priority. The high priority species to be analyzed first, are fin whales, minke whales and pilot whales, plus humpback whales for Canada. Norwegian large whale data will be available for the second analysis cycle. NAMMCO should ask David Borchers about the possibility of being contracted for the analysis of aerial survey data or at least to arrange it for the use of his software.

Opportunistic Surveys A decision must be made on who is going to validate and analyze these data too. And

206

NAMMCO Annual Report 2007 - 2008 also in this case, it is important to define uniform data validation criteria.

Data By this point it was clear that it is important to define uniform data validation criteria and that it should be emphasized to the cruise leaders that they should check the quality of the data as frequently as possible.

Data should agree with the IWC data availability policy if T-NASS (NAMMCO) data have to be accepted for use by the IWC for the implementation of an RMP.

An ad hoc Data Group to look into these questions will comprise: Geneviève Desportes, Phil Hammond, Greg Donovan, Thorvaldur Gunnlaugsson, Bjarni Mikkelsen, Nils Øien, Jack Lawson, Malene Simon and the NAMMCO Secretariat.

22. OTHER ITEMS

It would be particularly useful for finding good personnel for future surveys, to establish an information database on observers’ performance. No action was decided on this as it surely will clash with regulations on storing personal information in several countries.

A NAMMCO stall at the Marine Mammal Biennial Conference in Cape Town, South Africa, could house a T-NASS theme exhibit. There is unfortunately no time for submission of a T-NASS poster at the same conference as the deadline for abstracts is in May.

23. NEXT MEETING

It was agreed to aim at an analysis meeting in the spring 2008 (March-May).

24. ADOPTION OF REPORT

The report will be circulated for approval in draft form the week after Easter.

25. FINAL REMARKS

The Chair closed the meeting and warmly thanked Phil Hammond and SMRU for housing this meeting with great hospitality, exceptionally good food, a choir of grey seals outside the meeting room and amazingly good weather.

Report of the Planning Committee T-NASS WG III Appendix 2 Louise Burt: Comments on validation of SCANS Il shipboard visual survey data

The data that were collected on the visual survey were generally good. The cruise reports were useful and especially useful was a log of which transects were covered each day. Although primary observers didn’t like recording sightings on paper forms, the primary data generally had few problems or missing fields. The paper forms also meant that primary data were easy and quick to check. Validation fell into three categories; correcting minor typos, interpolating for GPS not working and checking of the tracker angle and distance measurements.

1. Minor errors There were minor typos that included things like using lowercase letters or codes such as cue or behaviour or using a single letter instead of the two letter code. This latter was OK if there was only one code beginning with that letter. More problematic was using codes that weren’t included in the list of possible codes. Other out of range values also occurred for aspect, glare left and glare right where the values were greater than 360. Records that had to cross-reference another record - i.e. duplicates or matches (same animal seen by 7x50 and “Big eye” trackers) - didn’t always cross-reference correctly. Platform code and button didn’t always match! Some problems with Transect numbers - missing, not always correct, didn’t correspond in effort and sightings.

2. GPS not working Occasionally the GPS would fail so that there would be missing sections in the GPS file, or it would get stuck so that from the GPS coordinates it looked like the vessel wasn’t moving although the vessel was on search effort. Sometimes there was a link in the effort or sightings data to the GPS file but then no corresponding record in the GPS file.

3. Checking tracker and angles This was the part that took the longest. Tracker angles and radial distances were checked if there were big discrepancies between the estimated values (obtained from the angleboard and reticules) and the ‘measured’ values (webcam and video). The commonest problems were 1. Not being able to find the video or webcam image 2. Couldn’t find audio file to check commentary 3. Record linked to wrong image or video 4. Couldn’t spot animal in the video 5. Video was blurred or horizon was unclear, fog or land 6. Webcam image was too bad to measure bearing (e.g. because of glare) 7. Angleboard estimate or radial distance missing from commentary 8. Not corrected for sighting abeam when measuring hearing from image 9. Pointer not aligned properly on angleboard 10. Typo in reticule or angle estimate 11. Not measuring bearings or distances carefully enough from images. 210

ANNEX 1.2 NAMMCO PLANNING COMMITTEE ON THE TRANS NORTH ATLANTIC SIGHTINGS SURVEY (T-NASS) WORKING GROUP IV SHIPBOARD SURVEYS DEBRIEFING Telephone meeting, 12 November 2007

1. CHAIRMAN WELCOME AND OPENING REMARKS

The Chairman expressed her profound disappointment at seeing that only two out of 7 Cruise Reports had been delivered to the TNASS Working Group in time for the meeting: the Faroes one and one of the Icelandic one. The first request for cruise report had been done by email on September 26. She reminded the delegates that T- NASS was a coordinated exercise under the auspices of NAMMCO, which had allocated special funding for the coordination. Big effort had also been put into it by the NAMMCO secretariat.

She underlined that the debriefing documents are an archive of information essential for the analysis and are an invaluable source of information for the future should NAMMCO again undertake the same kind of effort.

She questioned the delegates’ will to cooperate within TNASS and suggested the question of coordinated effort should come on the agenda in the future. She reminded the delegates that the website had to be updated, a final Press Release had to be done, a preliminary report provided to the NAMMCO Council, as well as to the IPY umbrella project. Elementary input data fundamental to these activities were missing from most of the countries, although most of them were already conducting analysis and had the information at hands.

2. ADOPTION OF THE AGENDA

Due to the lack of submitted material the Chairman decided to deal only with points: 8.2, 8.3, 8.4, 9, 10, 11 and 12, which was accepted.

3. APPOINTMENT OF RAPPORTEURS

Mario Acquarone volunteered to report from this meeting.

8. ANALYSIS STATUS AND PLANNING

8.2 Priority and deadlines for Analysis (also with reference to the T-NASS First Analysis Meeting, 2008 and the NAMMCO Scientific Committee Meeting, April 2008) Iceland, Greenland and Norway reported that they will give highest priority to the production of new abundance estimates for minke whales (all) and fin whales (Iceland and Norway) to be presented at the next IWC meeting. The figures will be used within the IWC Revised Management Procedure and, in the case of minke whales, they will 211

Report of the Planning Committee T-NASS WG IV be included into the IWC Implementation Review. In order to be considered at the IWC meeting in Chile in May 2008 the working papers will have to be submitted by the end of February 2008. It was noted that the Icelandic aerial estimate for minke and fin whales would also be presented there. Greenland mentioned that they planned to present new abundance estimates for all the big whales to the IWC.

The chairman noted that the above mentioned IWC February deadline will fall before the next NAMMCO TNASS meeting (April 5-7, see point 12), meaning that the T- NASS data would be presented to the IWC before being presented to and reviewed by a NAMMCO forum.

The Faroe Islands reported that they will give highest priority to the production of abundance estimates for pilot whales. There are no external deadlines, but there was money in 2007 allocated to this analysis, so it should start in 2007. They will begin by looking at sighting distribution and will decide which analysis they will perform based on the type of distribution.

8.3 Plan for Analysis (Who does what and when?) Iceland will in a first time analyze their shipboard data using standard Line Transect Analysis and will consider using BT analysis later. Thorvaldur Gunnlaugsson is in charge of this first type of analysis.

Greenland will also use standard Line Transect Analysis for their shipboard minke whale data and reported that they had very few primary sightings (about 20 minke whales and much less for other species) and therefore it was unlikely that they would produce reliable estimates for other species. Mads Peter was in charge of this analysis, which was well underway with preliminary estimate already produced.

Norway reported that they will start by analyzing minke whale data first and then proceed to fin whale data. The results of both species will be presented to the IWC.

The Faroes will cooperate with Iceland for the analysis. Iceland will be responsible for producing estimates from both minke and fin whale Faroese data, while the Faroes will take the lead for Pilot Whale data analysis. If they exist, pilot whale data from other areas than the Icelandic will also analyzed jointly with the Faroese. They would therefore be interested in knowing in which survey blocks there were pilot whale data. They were considering hiring and external analyst, probably someone from David Borchers’ lab, as was done in the past.

8.4 Acoustic data check-up and analysis The Chairman reported generally from the CODA debriefing meeting in St. Andrews and referred to the submitted material (SC/15/TNASS/35 and 36) for details.

Doug Gillespie (SMRU) has volunteered to check the quality and quantity of the TNASS Acoustic Data through random screening to better assess the need and possibility for detailed analysis. This was needed to find the right type and amount of funding for the analysis. The delegates agreed to send a copy of both the acoustics and 212

NAMMCO Annual Report 2007 - 2008 sighting database to Doug Gillespie at SMRU within the nearest future. Genevieve Desportes will re-con tact Doug to see how this could be best done and inform the delegates.

The Faroes noted that Phil Hammond (SMRU) had offered to include the Faroese acoustical data into the CODA data analysis. However he was not sure if this offer was sill valid and could not assess the timeframe for analysis. Also he thought that the Faroes data would be best analysed together with the other T-NASS data. He was ready to send the data for screening.

There was maybe some electrical noise on the Greenlandic recordings which might complicate or even impede any analysis. The Chairman noted that if Malene was not completely sure of the quality of the data, they could be sent to Doug, who had informed at the CODA meeting, that often parasite noise could be dealt with. Fernando Ugarte wondered if the data had not already been sent and will check with Malene what has happened with the Greenlandic acoustic data.

9. COOPERATION WITH CODA

9.1 Exchange of cruise reports between CODA and TNASS The Chairman referred to an email round that had been sent to the delegates about the exchange of cruise reports and reported that she had received the agreement of Gisli Vikingsson and had not received any opposition to or negative comments about this exchange from others.

As agreed CODA has sent their Cruise Reports to NAMMCO (SC/15/TNASS/35) as well as the minute of the CODA debriefing meeting (SC/15/TNASS/36). CODA expected to receive the TNASS Cruise Reports and the minutes of the T_NASS debriefing minutes in the nearest future.

9.2 Coordinated Data Analysis with T-NASS The Chairman reminded the delegates of CODA’s renewed interest to continue cooperation with TNASS, especially for spatial analysis.

10 PRESS RELEASE AND INPUT TO WEB SITE

The Secretariat reminded the delegates that for the production of a press release and for input to the NAMMCO web site they should provide before the end of this week: • The data of total planned and realised effort (missing for Greenland) • A general map of the realised effort (missing for Greenland, the two Norwegian vessels and two of the Icelandic vessels) • One map of the sightings for at least one species (preferably Fin Whale, missing for same as above). • In case the Delegates cannot produce the maps themselves they have the option to send the Logger Database to the Secretariat.

213

Report of the Planning Committee T-NASS WG IV

11 OTHER ITEMS

All the Delegates agreed that they will make their Cruise Report available to the Secretariat before end of November 2007.

Iceland expressed interest in analyzing the TNASS Extension Surveys data, for minke and fin whale.

12 NEXT MEETING

The next TNASS Working Group meeting is tentatively set to April 5-7, 2008 in Reykjavik, back to back with the IWC Fin Whale WG meeting. Gisli Vikingsson has promised that he will give feedback before the end of the week about the dates of the IWC meeting.

It was proposed to invite the following external experts, besides the external member of the T-NASS working group (Hammond, Donovan and Palka) • Hans Skaug • Someone from David Borcher’s lab • Dan Pike (his status is to be defined: as Icelandic Scientist or as Invited Expert).

ANNEX 1.3 NAMMCO PLANNING COMMITTEE ON THE TRANS NORTH ATLANTIC SIGHTINGS SURVEY (T-NASS) WORKING GROUP V Copenhagen, Denmark, April 7, 2008

1. CHAIR’S WELCOME AND OPENING REMARKS

Chair Genevieve Desportes welcomed participants (see Section 5) to the post-cruise meeting of the T-NASS Planning Committee. She pointed out that T-NASS had achieved a trans-Atlantic coverage (Fig. 1). The main purpose of this meeting was to carry out a general evaluation of the specific surveys and T-NASS in general, and to make recommendations that will improve future large-scale surveys.

4. REVIEW OF AVAILABLE DOCUMENTS AND REPORTS

Documents that were made available to the meeting are listed in Appendix 2.

5. SHIPBOARD EVALUATION

Cruise reports were available from the Faroese, Icelandic, CODA and SNESSA vessels. A log book was presented for the Greenlandic vessel and a verbal report for the Norwegian cruise in the eastern Barents Sea. Summaries are provided below.

Tulugaq (Greenland) – SC/15/TNASS/33 The vessel used a standard single platform procedure. There were no major technical problems with the platforms, but severe technical problem with the acoustic equipment, and sounds were only collected for part of the survey. However, the need to refuel (at least every 10 days) and reload water (every 4 days), as well as a transit to Nuuk in the first days, which were not included in the time schedule used for designing the effort, made it impossible to cover the designed track.

The prevalent bad weather (either fog or wind) also resulted in a poor coverage of most of the blocks, with the small north eastern block and the south block not covered at all. Harbour facilities on the Western Greenlandic coast give little potential for re- design of the survey as it progresses.

A total of 814 nm of effort was achieved, which represents 38% of the planned coverage of 2,129 nm. A total of 57 cetacean sightings were made by the three single platforms of which some are duplicate. Common minke and humpback whales were the most commonly seen species, with 35 and 8 sightings respectively (Table 2); 152 sightings of seals were also made. The survey clearly underestimated the number of humpback whales, as is evident from the number of incidental sightings in near shore and fjord areas not included in the survey coverage.

Venus (Iceland) – SC/15/TNASS/30 Venus was responsible for a survey area North of Iceland delimited by the eastern coast of Greenland and bounded by c. 24° W and 4° E longitude, and 70° N and 74° N latitude (2 blocks north and south), as well as a survey area between the Icelandic Westfjords and the coast of Greenland. The vessel originally rented for the survey was unable to sail, resulting in a lost of 5.5 days of survey time. The survey eventually started on July 3 in Tórshavn and ended on July 23 in Reykjavík, resulting in 17 days of effort after subtracting time for transit to and from the survey line.

The survey, conducted in passing mode, followed the standard Buckland and Turnock (BT) procedures decided upon at the planning meeting for the Faroese and Icelandic vessels and similar to that followed by the CODA vessels, as described in the common T-NASS observer guidelines and the guidelines for cruise leaders. The Primary Observers searched with naked eyes in a standard way for line transect surveys, the Tracking Observer searched with binoculars, one 7×50 on a monopod and one pair of 220

NAMMCO Annual Report 2007 - 2008

25×150 (2.7°) “Big Eyes” mounted on a solid adjustable monopod. Each TP position was equipped with a double video system. A web camera taking pictures of the angle board on the floor (for the subsequent measure of the angle to the sighting) and a high definition digital video cameras recording the sea surface and horizon (for the subsequent measure of the distance to the sighting on video images). Video recordings were triggered each time a sighting/resighting button was pressed. An audio system and computer connection allowed communication between the primary and tracker platform and the data recorder and direct recordings of sightings events and voice. Unfortunately the HD video and communication systems never worked properly while the web cam systems worked at all times. When the vessel was progressing on the track and there was no ice present, she would tow a small hydrophone array (3 elements) situated at the extremity of a 200 m cable for recording high- and mid- frequency underwater sounds, such as echolocation clicks.

Survey progress was impaired by bad weather and only 891 nm were covered on effort, with 758 nm and 134 nm respectively in the northern and western blocks and no effort at all in the northernmost block. This corresponded to 51%, 36% and 0% of the intended effort in the respective blocks, with 30% of the total planned effort actually covered. The western block was very poorly covered because of bad weather in addition to extensive ice cover.

A total of 173 groups of cetaceans were encountered. There were 29 duplicates identified. Eight different species were identified during the cruise. The most frequently encountered species was humpback whales (66 sightings/17 duplicates), followed by white beaked dolphin (25), fin whale (20) and minke whale (19). The computer folders containing the sound recordings from Venus were 6.69 GB for high frequency, 510 GB for middle frequency and 36 GB for clicks.

The survey suffered a 5-day delay at the start because the first vessel chartered was deemed unseaworthy. Consequently, there was a lack of time for training the observers in the new and demanding procedures. Although the procedures were in theory judged satisfactorily, many proved difficult to follow in practice because of the technical problems encountered with the sound and video recording systems delivered by the Sea Mammal Research Unit, which did not perform as expected. Some of the observers were not considered the best choice for the type of technical survey conducted. Several points for improvement were given in the cruise report.

Árni Friðriksson (Iceland) – SC/15/TNASS/29 MRI's research vessel Árni Friðriksson, RE 200 participated in the T-NASS from 25 June to 25 July 2007. As in 2001 this cruise was a combination of an acoustic redfish survey and cetacean sightings survey. The vessel covered the Irminger Sea area between Iceland and Greenland south to 57°N. The survey design was based on the BT mode developed for the 1994 SCANS survey in the North Sea and adjacent waters. Some modifications were made to account for the primary target species (fin whales and common minke whales).

221

Report of the Planning Committee T-NASS WG V

Preparations for the survey were severely hampered by a long delay in the arrival of the equipment that was delivered in the mid day on the day of departure. This prevented the scheduled training sessions and proper setup and testing of the equipment prior to departure. A few days after the start of the survey Germany decided to withdraw from the redfish/cetacean survey because of technical problems with their vessel. This necessitated a re-design of the survey area covered by R/S Árni Friðriksson.

Most of the observers had experience from previous cetacean sightings surveys and no major problems were associated with the quality of the observers.

Various technical problems were encountered throughout the survey including malfunctioning of the mid-frequency sound card, microphones, video cameras, webcams and inter-communication system. The “Big-Eye” also proved to be impossible to use due to vessel motion and was exchanged for a 7×50 binocular after few days of survey.

A total of 2,027 nm was covered on effort under varying conditions. Around 90% of the effort was conducted in sea state less than 5. The total area of the two blocks covered by AF was 845,000 km2.

Coverage near the east coast of Greenland was very poor due to extensive ice and associated fog. This was particularly unfortunate, as this area is known from previous surveys to have high densities of the two primary target species: fin and common minke whales.

Distance experiments were conducted using an inflatable boat and the radar of the vessel. These indicated a negative bias of distance estimation by the primary platform of 9.7%. The mean error in angle estimation was 2-3 degrees.

A total of 443 cetacean sightings were made, comprising 1,479 animals. A total of 11 species were identified plus beaked whales that could not be identified at the species level. The most commonly sighted species was the fin whale (237 sightings, 319 animals). This is in accordance with previous surveys in this area. The second most common species in terms of sightings was the long-finned pilot whale (45 sightings, 539 animals). Other commonly-sighted species include humpback whales, sei whales, sperm whales and four species of dolphins (including the killer whale). In spite of the many difficulties encountered, the objectives of the cruise were accomplished successfully.

Jákup B (Iceland) – SC/15/TNASS/31 The vessel Jákup B rented by the MRI from Faroes, surveyed the SC block. The vessel was embarked in Torshavn and completed most of the planned track successfully, although a large part of the track was covered during poor conditions due to bad weather that prevailed for the first half of the period. A distance exercise was conducted early in the survey and a distance experiment on the last day. The 222

NAMMCO Annual Report 2007 - 2008 experience with equipment was generally the same as on the other MRI vessels. The tracker platform was rather low and not suitable for “Big-Eye” tracking (×25 magnification) except in good conditions. The vessel was otherwise suitable and the crew cooperative. Most of the observers had extensive experience and the operation ran smoothly during long working hours. The vessel frequently slowed down or turned on sightings abeam for species identification and school size estimation. Densities were generally low and distribution was similar to earlier surveys in this area. A total of 2,500 nm was covered on effort under varying conditions. Around 90% of the effort was conducted in sea state less than 5. The total area of the block covered by Jákup B was 119,000 nm2.

A total of 166 unique cetacean sightings were made, with 9 species identified and beaked whales that could not be identified at the species level. The most commonly sighted species was the fin whale (69 sightings) followed by the sperm whale (27).

Thor Chaser (Faroes) – SC/15/TNASS/32 The vessel originally planned for the survey became unavailable just before the survey started, leading to the need of replacing it and a delay in departure of three days. The vessel Thor Chaser surveyed the Faroese part of T-NASS during the period 1-22 July.

During 20 survey days the vessel realized 2,818 km of trackline, which was 55% of the planned effort. 2,346 km (83%) was completed in double-platform mode and 472 km (17%) in single platform mode. Realized effort inside area IF-E was 752 km (corresponding 45% of planned effort), inside IF-SE-N 1,800 km (87%) and inside IF- SE-S 263 km (19%). 49% of total effort was completed in Beaufort 2 or less, while the proportion effort completed in Beaufort 4 and greater was 35%.

Half of the observers had experience from cetacean sightings surveys and the rest were recruits. The major problem associated with the quality of the observers was species identification. A distance exercise was conducted early in the survey and a distance experiment on the last day.

A total of 105 groups of cetaceans were encountered. There were 20 duplicates identified. Species most frequently encountered were pilot whales (14 sightings), bottlenose whales (13 sightings) and harbour porpoises (10 sightings). The low realized effort was due to a combination of a delayed survey start and unfavourable weather conditions far north and south in the survey area. The folders containing the sound recordings from Thor Chaser were 20.3 GB for high frequency, 888 GB for middle frequency, 1.5 MB for whistles and 5.15 GB for clicks.

Norway – SC/15/TNASS/34 The Norwegian survey in 2007 was the last year’s survey of a six-year cycle with the main purpose of estimating abundance of minke whales in the Northeast Atlantic. The area surveyed in 2007 was the Barents Sea east of 28ºE. The basic survey procedures followed were those established in 1995, but some modifications have been made to equipment and software used over the years. Double platform effort was used 223

Report of the Planning Committee T-NASS WG V exclusively, and the observers were organised into teams of two persons, and this has been consistent in all the Norwegian whale surveys since 1996. In total, about 2,300 nm were surveyed with primary effort in July. From the primary platform 88 sightings of minke whales were made. Other sightings include 99 dolphin sp., 37 harbour porpoise, 15 fin whales and 11 humpback whales.

CODA – SC/15/TNASS/35 Since 1994 there have been two major surveys (SCANS and SCANS II) of the European continental shelf to generate estimates of cetacean abundance and to contribute to an assessment of the impact of bycatch. In contrast, European offshore waters have only been partially surveyed and the abundance estimates generated suffer from several sources of bias. Offshore surveys to generate unbiased abundance estimates are especially important to complement on-shelf surveys for species that are distributed in both habitats. The aim of the CODA project was to generate new information on the distribution, abundance and habitat preferences of cetaceans in the offshore European Atlantic; these data will contribute to bycatch assessment for common dolphin and to our understanding of the effects of military and industrial activities on deep divers. The survey area included offshore waters of the European Fishing Zone west of the UK, Ireland, France and Spain. Shipboard surveys were carried out during July 2007. Line transect methods were used to collect double platform visual survey data to allow analyses to account for the probability of detection on the transect line to be less than one and for responsive movement of animals to the ship. Passive acoustic data were also collected on survey ships for all species. Five ships covered 10,000 km of transects in an area of 967,538 km2. Sightings amounted to just over 1,500 encounters of seventeen species. Fin whale encounters were greatest and centred in the Bay of Biscay and further West. Common dolphins occurred mainly in the southern part of the survey area. Sperm whales and three Ziphiid species were recorded throughout the area. Abundance estimates will be calculated where data allow. Estimates for the common dolphin will be incorporated into a management framework that was developed during SCANS II to allow safe bycatch limits to be determined.

SNESSA – SC/15/AE/8a, SC/15/AE/9 During 30 July to 29 August 2007, a NOAA team based at the Northeast Fisheries Science Center conducted an abundance survey using an aircraft and ship in waters from Cape Hatteras, North Carolina to the Bay of Fundy, from the coast to beyond the 2,000 m depth contour. The shipboard survey (using the R/V Henry Bigelow) was concentrated in the coastal waters in the Gulf of Maine, the aerial survey (using a NOAA Twin Otter) covered the rest of the area. The shipboard results are reported in the document SC/15/AE/9, the aerial results are reported the document SC/15/AE/8a. The primary objective for the shipboard and aerial surveys was to determine the spatial distribution and abundance of cetaceans, sea turtles, and seals in the study region. In addition, the shipboard survey also had the following objectives 1) determine the spatial distribution and abundance of seabirds, 2) use passive acoustics to record vocalizing cetaceans by a team of people, and 3) conduct oceanographic sampling (e.g., CTD and bongo casts) to help define the habitat throughout the survey region about three times a day. On the ship, two teams visually surveyed for 224

NAMMCO Annual Report 2007 - 2008 cetaceans, seals and sea turtles using the BT procedure with a visual primary team and a “Big-Eye” tracker team, while surveying at about 11 knots, and another team visually surveyed for seabirds using the standard strip transect procedure. About 2,970 km of track lines were surveyed, of which about 2,400 km of track lines were conducted in good weather conditions (Beaufort Sea States less than or equal to 3) and will be used in the abundance estimates. Two visual teams identified 14 species/species groups of cetaceans, and no turtle species, which consists of about 900 uniquely-identified groups. Another visual team identified 13 non-seabird species and 34 seabird/water species, which totalled 2,749 groups (17,109 individuals). Despite technical problems and loss of equipment, the passive acoustic high-frequency system operated for 785 km and the mid-frequency system operated for about 2,400 km. In addition here were 42 stations where bongo nets and CTDs were deployed to collect plankton and temperature/salinity data. Abundance estimates derived using the visual cetacean data are being produced.

Compared to CODA/T-NASS BT procedure, SNESSA implemented a BT setup without communication between the primary and tracker platforms, with duplicate determined a posteriori, thus requiring much simpler equipment. The two trackers each had their own data recorder (a Fujitsu Stylistic Tablet PC), which recorded data on a hand-held computerized data sheet (in-house NMFS software) that used both touch pull-down menus and hand-writing recognition fields. The three primary observers recorded their data on the same type of computer. The procedure performed very well, with no technical problems.

5.1 Cruise preparation, incl. vessels, platforms and equipment (T-NASS) It is obvious that preparation for the cruise was less than adequate in some areas. Problems identified include: • The planned effort was more than could be reasonably achieved by some of the vessels even with very good conditions. This was especially true for the Greenlandic vessel because the endurance of the vessel was less than expected, and also for the other vessels due to a misspecification of available sea days. • Two ships became unavailable, one due to its unseaworthy condition and the other due to contractual issues. This required changing ships at the last moment and resulted in a loss of several days of effort. • The equipment ordered from SMRU arrived very late in one case, at mid-day on the day of the vessel’s departure. The platforms were not installed on 3 charter vessels in the Faroes as had been planned and the vessels were not in the same harbour. This made the setup and testing of equipment and the planned one-day training of the observers on equipped vessels impossible in all cases. • The Leviathan brand “Big-Eye” binoculars were found to be nearly unusable on the two vessels that employed them, due to excessive vessel movement and/or vibration combined with poor optics. The Canadian “Big Eyes” were found excellent on one vessel and difficult to use on another vessel, probably

225

Report of the Planning Committee T-NASS WG V

due to differences in vessel stability. This was detrimental to the effectiveness of three of the tracker platforms. • There were numerous technical problems with the audio and video equipment and the survey software that in some cases were never resolved. A particular problem was incompatible/ malfunctioning external sound cards which prevented the recording of audio. In addition communication between the platforms was very poor, which is problematic for the implementation of the BT method as planned. • The media (external hard drives) meant to record the videos for distance estimate did not worked properly on any vessels.

The Working Group made the following recommendations to avoid recurrence of these problems in future surveys. 1. All prospective vessels should be thoroughly inspected by a knowledgeable person before they are contracted. The general condition and seaworthiness of the vessels, as well as their suitability as survey platforms, including autonomy for fuel and water, should be assessed. If possible a certificate of seaworthiness should be provided and the vessel should be tested at sea. 2. Equipment should be ordered and received well in advance of the survey, and should be thoroughly tested in the lab and onboard the vessels before departure. 3. The Cruise Leaders should meet together well in advance of the survey, and all equipment should be available for inspection and use at the meeting. This will better enable the Cruise leaders to work out problems the equipment and protocols before the survey begins. A pilot/training survey should be conducted with all cruise leaders onboard. 4. All vessels must be thoroughly prepared (e.g. platforms mounted) and equipment mounted before observer training begins. 5. Adequate time must be allocated for observer training before departure. This should include at least one day of class training, and one day of practical training onboard the vessels. 6. Backup equipment, ideally duplicates of all major items, should be purchased for each vessel. 7. The protocol should include detailed instructions on alternative methods in cases of equipment failure. 8. Observers on each vessel should be designated and trained as technical experts on each type of survey equipment, and they should be responsible for onboard repair and maintenance.

5.2 Data collection procedures (T-NASS) Due to the equipment problems encountered most of the vessels had at times to revert to paper forms to record data. Some problems were noted and recommendations for improvements made.

1. Use of the “Big Eyes” seemed to depend on the stability of the platform and the willingness and determination of the trackers to persevere in using them. 226

NAMMCO Annual Report 2007 - 2008

If “Big Eyes” are to be used in future surveys, special attention should be given to the stability of the vessels and platforms. Further training on the proper setup and use of these would be useful. 2. A better data recording system, possibly using weatherproof computers with touch screens, should be developed and used. The recording system should be fully field tested well in advance of the survey. 3. Consideration should be given to having a dedicated data recorder for the primary platform. 4. There should be frequent meetings of the cruise leader and observers to identify and resolve procedural problems, particularly early in the survey, and to receive feedback from the observers. These could be combined with data validation. 5. The cruise leader should regularly review the sightings performance of the observers, with regard to radial distances and angles and species identifications.

Other measures that should be considered which might improve the methodology include:

6. The tracker platform should continue tracking sightings until the sighting comes abeam, even if it is identified as a duplicate by the Data Inputer (DI). 7. Trackers should also confirm sightings initially made by the primaries when feasible. 8. Trackers should adhere to tracking only sightings that are likely to come close to the trackline. 9. The role of the trackers when there is a dispersed sighting should be reconsidered, in that their efforts may be better applied to mapping and identifying the sighting as a whole rather than tracking a single group.

5.3 Evaluation of observers (T-NASS) Some of the observers were unsuitable, for example in failing to follow the protocols despite repeated reminders, and not working well in a team environment. On one of the vessels language was an issue.

Specific recommendations include: 9. If required survey guidelines and protocols should be provided in the native language of the observers who will use them. A simplified guide should also be provided to the Captain and crew. 10. All observers should be evaluated after the survey by the CL’s based on specific criteria, and these evaluations should be given to the observer and kept on file for future reference. 11. Observers should be required to provide references and these references should be consulted before contracting. 12. Observers should have a medical examination, including a vision test, before departure. Observers should know their focus settings for binoculars. 13. Observers should be chosen for their observer quality coupled with social skills and dedication for the project. 227

Report of the Planning Committee T-NASS WG V

5.4 Feedback from observers (T-NASS) No formal feedback from the observers was provided to the meeting, although all cruise leaders held informal discussions with observers during the survey. It was recommended that a formal meeting be held at the end of the cruise to gain further input from the observers. Another effective mechanism might be to have a suggestion book onboard that can be used at any time.

5.5 Completed effort (amount and distribution) vs planned (T-NASS) Overall coverage was less than planned (Table 1, showing planned and realized effort by stratum), primarily due to 1) the withdrawal of the German vessel from the redfish survey which necessitated a reallocation of effort by the other vessels, 2) the late start of the Thor Chaser and Venus and 3) the unknown necessity of refuelling and taking water for the Tulugaq. Unusually poor weather (fog and high winds) also reduced coverage in some areas. However it is also the case that planned effort was overoptimistic given the number of sea days available: this appears to have resulted from an overestimation of available sea days for the Greenlandic and Faroese vessel and the Venus. Two blocks (South Greenland and IF-N-N) were not surveyed at all. Coverage was particularly poor near East Greenland, off NW Iceland, NE Iceland and in the southern part of the Faroese blocks. Nevertheless it was considered that coverage was adequate for abundance estimation of the target species in all areas except perhaps minke whales in offshore areas of the central North Atlantic. It was recommended that the survey design be based on realistic assessment of available ship time, using the achievements of past surveys in the specific area as a guide. The endurance capabilities of the vessels must also be considered.

5.6 Quality of collected data (e.g.: angle, distance …) (T-NASS) Comparison of perpendicular distances to duplicate fin whale sightings measured by the tracker and primary platforms on the Faroese and Icelandic vessels suggests that, assuming the tracker measurements are accurate, the primary measurements are negatively biased. However it was noted that these were not measurements to the same cue, and that the primary platform might be more likely to spot whales that are moving towards the transect than those that are moving away from it. An alternative explanation would be that fin whales are attracted to the vessel. The CODA data exhibited the same features. It was recommended that further work should be done comparing the distance measurements of the two platforms to duplicate sightings, paying particular attention to measurements made close together in time. Gunnlaugsson agreed to lead this work.

5.7 Distance experiment While it was acknowledged that distance experiments were useful as a training aid, their usefulness for bias correction was questioned. Therefore it was recommended that distance experiments be conducted primarily as a training exercise at the beginning of the survey and possibly at intervals throughout the survey. It was also recommended that the nature of distance experiments be revaluated and if appropriate a standard method of conducting these experiments be documented.

5.8 T-NASS Cooperation with SMRU regarding equipment and guidelines 228

NAMMCO Annual Report 2007 - 2008

As previously noted the equipment was received very late, apparently due to the late reception of the equipment order due to a misunderstanding. Some of the equipment (e.g. the computer sound cards) malfunctioned from the beginning and almost all other items malfunctioned to varying degrees, sometimes irreparably. Some of the items were found not to be robust to the shipboard environment. It is likely that the equipment was inadequately tested because of its “last minute” production, and its late arrival meant that it could not be thoroughly checked before departure (in one case it was installed after departure!). It was recommended that feedback be provided to SMRU on the T-NASS experience with these equipment sets, so that improvements can be made. Víkingsson agreed to lead this.

5.9 T-NASS cooperation with SMRU regarding land back-up during the cruise The staff of SMRU was helpful and cooperative in attempting to resolve equipment problems during the cruise. In this regard particular thanks are given to Doug Gillespie and Russell Leaper.

5.10 T-NASS coordination between vessels Communication between the vessels at sea was considered important to monitor progress, cooperate in filling in gaps in coverage, and helping to resolve equipment problems and protocol issues. However some vessels were out of communication for extended periods. It was recommended that a regular communication schedule be established between vessels in future surveys.

5.11 Input from CODA and SNESSA Refer to specific sections under point 5.

5.11.1 Comparative success in implementing the BT methodology on SCANS II, CODA, SNESSA and T-NASS More problems were encountered in implementing BT in T-NASS than in SCANS II and CODA, primarily due to equipment problems and perhaps also to insufficient training and experience. The problems of implementing the method could be overcome in future surveys through improvements in equipment and better observer training. It was also noted that alternative BT modes, such as that used by SNESSA were less technically complex and equipment dependent. SNESSA had a good success in implementing the BT methodology with an alternative and less technically complex procedure. This alternative should certainly be investigated for future surveys.

Nevertheless the BT method was considered the best method available for cases where perception and availability biases were expected and responsive movement was a possibility. The need to use BT as opposed to simpler methods, such as a single platform survey, is to a large degree dependent on the target species and the biases that might be expected. For fin whales preliminary estimates of g(0) have been close to 1 and responsive movement is not expected (but see 5.6). Therefore a single platform mode would be adequate for this species and more efficient in terms of use of observers. For other species such as minke and pilot whales, g(0) may be low and responsive movement is expected. Therefore a BT type mode is required if absolute

229

Report of the Planning Committee T-NASS WG V abundance estimates are desired for these species.

5.12 Overall evaluation and what to remember next time The many problems noted above should not detract from the fact that the T-NASS ship survey was generally successful in achieving its objectives. There will always be problems in mounting a large and complex cooperative project such as T-NASS, and very important that these problems be adequately documented and that we learn from them. To this end the recommendations for improving future large scale ship surveys are detailed in Appendix 4.

Cetacean surveys are becoming increasingly technical; the time needed for a thorough preparation has consequently increased. This needs to be acknowledged and kept in mind for future surveys.

6. AERIAL EVALUATION

Cruise reports were available for all surveys: Icelandic, Greenlandic, Canadian, and SNESSA. Summaries are provided below.

Iceland The Icelandic aerial survey component of the T-NASS project was a continuation of a series of surveys, using nearly identical design and methodology, conducted in 1987, 1995 and 2001. Target species, in order of priority, were minke whales, harbour porpoises, and humpback whales. However all species encountered were recorded. One of the primary observers was highly experienced in aerial surveys for harbour porpoises, while the other had previous experience with minke whale surveys. The survey design and methodology (cue counting for minke and baleen whales, line transect for others) was identical to that used in 2001, except that some additional effort was flown in fiords and high-density areas on an opportunistic basis, and the survey was flown at 600 ft rather than 750 ft as previously. In addition sea surface temperature data were collected using an infrared temperature probe. Of the 30 days the plane was available, at least some effort was flown on 20. Unlike in previous years pack ice covered much of the north-western part of the survey area, including the northern part of Block 3 and the western parts of Blocks 4 and 5. Pack ice coverage ranged from 0 to 90% in these areas. Total realized effort was 79% of planned effort, not including double coverage in some areas and the additional fiord effort. 95% of realized effort was flown at Beaufort Sea State 3 or less. A total of 70 unique sightings of minke whales were made by the primary and secondary observers. The sighting rate for minke whales was much lower than in previous surveys in almost all areas. The harbour porpoise was the most frequently sighted cetacean in this survey. Harbour porpoises were seen in all strata but were most common in inshore areas and particularly off western Iceland. Humpbacks were most frequently sighted to the NW of Iceland and appeared to be strongly associated with the ice edge in some areas. Unlike in 2001 few humpbacks were sighted off eastern Iceland, but parts of this area were not covered. White-beaked dolphins were seen in all blocks but were most common to the North and N.E. of Iceland. Other species encountered at low frequency 230

NAMMCO Annual Report 2007 - 2008 include fin, sperm, pilot and beaked whales, and white-sided and bottlenose dolphins. The survey was generally successful in covering the area and no serious problems were encountered. Recommendations to enhance the success of future aerial surveys are provided in Appendix 3.

Canada The Canadian study area extended from Cape Chidley, Labrador, down to the Scotian Shelf (SS) to meet the SNESSA effort in the Bay of Fundy. There were three aircraft involved, with 9 observers on effort. This survey provides full coverage of the Atlantic Canadian coast for the first time, covering the eastern coast of Canada that have not been surveyed completely in earlier surveys, or in some cases, at all.

The survey methodology was as similar as possible to that used previously in Canada, and the adjacent U.S. NMFS survey area (SNESSA) to maintain consistency. A single Twin Otter 300 was used in the NL survey, while a pair of Cessna Skymaster 337s was used simultaneously during survey effort in the Gulf and SS surveys. All observers were highly experienced, and had participated in training and practice surveys prior to the T-NASS effort.

On the Twin-Otter sightings were recorded using a dedicated survey programme which was GPS-linked, and also recorded input from the sea surface temperature probe in the belly of the aircraft. Declinations to sighted animals were made using hand-held inclinometers. On the Skymaster, sightings data were recorded onto handheld audio recorders and transcribed to computer as soon as possible after each survey day.

The NL crew consisted of a pilot, co-pilot, a single forward observer on the left, forward and rear observers on the right, and a navigator/data recorder. On the Gulf and SS, there were two independent observers, one on each side of each Skymaster aircraft. The two aircraft alternated the lines that they flew each day, so a single aircrew did not survey any one portion of a stratum alone.

All marine megafauna species encountered (with the exception of seabirds) were recorded, although in the NL survey area pinniped sightings were rarely recorded as they were infrequent, and DFO uses other means to estimate their abundance. Sighting angles and species identification were checked each night during the survey of the NL portion, as the data were recorded onto the computer in real time during each flight.

Newfoundland and Labrador Most of the planned transect lines were flown, and most in good to very good sea states and sightability conditions (Canadian survey report Figs 2 and 3), with effort conducted from 17 July to 24 August, 2007. Some modifications to the Distance-based survey design were required for logistical purposes. Primarily, the team had to reduce survey coverage in several areas off the Labrador coast and off the Newfoundland southeast coast due to range limitations of the aircraft. Transect lines were re-drawn to maximize coverage while staying within operational limits.

231

Report of the Planning Committee T-NASS WG V

Eighteen species were sighted (Table 2). The most commonly-sighted animal was the humpback whale, with relatively large numbers of sightings of Atlantic white-sided dolphins, fin whales, white-beaked dolphins and sunfish (Mola mola). Most sightings occurred in the southern stratum of the survey area, with relatively few along the Labrador coast (Canadian survey report Tables 2 and 3, and Fig. 4). Also, more sightings were made later in the survey period than initially (not just confounded by survey locality).

Gulf of St Lawrence and Scotian Shelf Survey coverage was extremely good over this survey area, with effort conducted from 21 July to 27 August, 2007. Almost all planned transect lines were flown, and most in good to very good sea states and sightability conditions. Some modifications to the Distance-based survey design were required for logistical purposes and the planned equal-angle zig-zag transects were replaced with parallel transects spaced 10 nm apart.

The two Skymaster teams reported more than 1300 megafauna sightings, with 19 cetacean species identified and higher sightings rates in the Scotian Shelf than in the Gulf (Table 2).

Greenland The aerial survey off West Greenland was conducted between 25 August and 29 September 2007. The survey platform was a Twin Otter operated by Air Greenland with four observer platforms and long range fuel tanks. Observations for cetaceans were conducted from four bubble windows and were recorded and geo-referenced onto a Redhen msDVRs system that also allowed for continuous video recording of the trackline as well as vertical digital photographic recordings. In addition sea surface temperature was recorded every two minutes on a separate computer.

The survey, conducted as a line transect survey with cue counting data collection for the three target species – minke, fin and humpback whales – was planned to systematically cover the banks off West Greenland from Uummannaq in the north to southernmost tip at Kap Farvel. East-west oriented parallel transects were chosen for most areas except for south Greenland were north-south oriented transects were deployed. Complex fjord systems were covered by a zigzag transect-design.

The survey covered a total of 220,924 km2 and the accomplished effort was 9,434 km flown in sea state 5 or less, of which 5,285 were flown in sea state 3 or less. In terms of effort for cue counting estimation this corresponds to 190,163 seconds in sea state 5 of which 126,290 seconds were flown in sea state 3 or less. White-beaked dolphins were the most commonly seen species followed by harbour porpoise, then common minke, fin and humpback whales (Table 2).

SNESSA During 30 July to 29 August 2007, the Northeast Fisheries Science Center conducted an abundance survey using an aircraft and ship in waters from Cape Hatteras, North Carolina to the Bay of Fundy, and from the coast to beyond the 2000 m depth contour. 232

NAMMCO Annual Report 2007 - 2008

The shipboard survey (using the R/V Henry Bigelow) was concentrated in the coastal waters in the Gulf of Maine, and the aerial survey (using a NOAA Twin Otter) covered the rest of the area. The primary objective for the aerial survey is to determine the spatial distribution and abundance of cetaceans and sea turtles in the study region. The airplane flew at 600 feet above the water surface at about 110 knots and the circle-back (Hiby) data collection methods were used, where circles were performed on groups of cetaceans and turtles that had 5 or less animals per group. There were about 8,900 km of on-effort track lines that were conducted in Beaufort 3 or less and will be used in calculating the abundance estimates. On these track lines, there were 15 species of identifiable cetaceans, and four turtle species detected. There were 98 circle-backs performed on 20 species/species groups that can be used to estimate g(0) for these species. The abundance estimates procedures using these data are underway.

6.1 Cruise preparation, including platforms and equipment Preparations for the aerial surveys were generally considered to have been adequate in all cases. Minor modifications were made to the Canadian transect design because of logistical considerations. While minor equipment problems were encountered by all teams, the only serious one was the non-functional SST software in the early part of the Icelandic survey, and this did not detract from whale observations.

The survey platforms were adequate in most respects. The Twin Otter platform was preferred because it is relatively large, can carry more observers and uses Jet A fuel, which is more readily available than the Avgas required by the Partenavia and Skymaster. However it costs significantly more to use which will reduce available effort. The secondary platform on the Partenavia was considered less than adequate because it does not afford a good view of the transect, which is important for g(0) estimation using double platform methods. It was noted that experiments are ongoing in Canada and other areas in the use of drone aircraft, so this might be a possibility in the future.

The use of the large Arcturus aircraft by Canada was unfortunately cancelled. It was considered that this platform was promising for covering large offshore areas and it was recommended that its use should be further investigated.

Lightweight immersion suits (pilot suits) were used for the first time in Iceland and these were found to be comfortable and convenient. It is undeniable that they could save lives in some situations. In addition one of the observers had received underwater escape training and shared this experience with the crew. These safety measures were also implemented in SCANS II, and it is recommended they be used in future aerial surveys.

6.2 Data Collection procedures The data collection procedures were similar between Iceland and Greenland but differed from those used by Canada and SNESSA. The single platform observer procedure used by Canada on the Skymaster platforms does not provide a way to estimate availability bias, so this will be an issue when absolute abundance estimates 233

Report of the Planning Committee T-NASS WG V are estimated. The double platform procedures employed in the Twin Otter team surveying the NL part of the Canadian survey will allow for estimation of g(0) however. A test flight during which the two Skymasters flew along the same trackline as the Twin Otter, in relatively close in-line formation, provided a low number of duplicate sightings data to conduct a comparative analysis of detection probability, and thus corrections to the Skymaster data will likely be not be possible using this method.

Pike provided recommendations for the improvement of procedures in the Icelandic survey, including minor changes to the protocol and the development of a protocol for very large schools; these are detailed in Appendix 3. The use of high definition video as a secondary platform should also be investigated. Such systems are relatively inexpensive, compact and have excellent resolution. The use of such a system might make a manned secondary platform unnecessary. It was recommended that this be further investigated.

The change in survey altitude from 750 to 600 ft in the Icelandic survey did not seem to detract very much from the effectiveness of the survey for minke whales and certainly improved its effectiveness for harbour porpoises.

6.3 Evaluation of observers Most of the observers used in the aerial surveys had previous experience, and all received what was felt to be adequate ground and flight training.

Past experience has demonstrated the value of monitoring the observers closely during the survey and providing feedback to them on a regular basis. While this is relatively easy if the data are entered onboard the plane, it has proven difficult in cases where the data are recorded orally. The employment of a ground crew to enter data in the Icelandic survey greatly facilitated this process and should be continued in future surveys.

6.4 Feedback from observers The cruise leaders consulted with the observers in the preparation of the cruise reports.

6.5 Completed effort vs planned Table 1 shows the planned effort vs the effort realized under acceptable conditions. Realized effort was excellent in almost all areas, and spectacularly so in Canada. Some small portions of the Icelandic area, particularly the NE and SE “corners”, were missed because of persistent bad weather. Some areas were surveyed twice or received additional effort. Two planes were used to cover parts of the Canadian area, and this strategy could be considered for other areas.

6.6 Quality of collected data This is presently under evaluation, but no serious issues have as yet arisen.

6.7 Distance experiment 234

NAMMCO Annual Report 2007 - 2008

Distance experiments were not carried out.

6.8 Coordination between planes Three aircraft were used in Canada, and there was close coordination between these and the neighbouring SNESSA crew. The cruise leader of the Greenlandic survey received training in the initial part of the Icelandic survey. Close coordination between other areas during the survey was considered unnecessary as the survey areas were not contiguous and somewhat different methods and equipment sets were used.

6.9 Overall evaluation and what to remember next time Generally the aerial portion of T-NASS was considered successful and relatively unproblematic compared to the ship-based survey. Specific recommendations are provided in Appendix 4.

7. SPECIAL MODIFICATIONS IMPLEMENTED FOR ENCOMPASSING HARBOUR PORPOISES

Such modifications were mainly implemented in the Icelandic aerial survey, see Appendix 5. for details. They include the use of an experienced harbour porpoise observer, a reduction in altitude from 750 to 600 ft, and the implementation of special strata in some of the fjord systems.

The use of an experienced harbour porpoise observer (from SCANS II and other surveys) in the Icelandic survey was considered a success in that the number of harbour porpoise sightings increased dramatically compared to earlier surveys. However in surveys designed to estimate the abundance of both small and large whales it is also important that an optimal searching pattern be used.

The secondary fiord strata attempted in Iceland were, however, only partially successful because of persistent high winds in some of the fiords. It was also found that harbour porpoise densities were not particularly high in those areas flown. Therefore these strata should not have high priority in future surveys, but could be flown on an opportunistic basis.

Overall, the modifications implemented were thought to be satisfactorily and commended by the Working Group. They will lead to the first reliable harbour porpoise abundance in Icelandic coastal area.

8. T-NASS EXTENSION EVALUATION

Three Extension survey efforts covered areas adjacent and to the south of the main T-NASS survey area at approximately the same time that T-NASS was in progress.

1) The MAR-ECO research programme placed one vessel (from UK) along the North Atlantic Ridge north of the Azores, and especially around the Charlie Gibbs Fracture

235

Report of the Planning Committee T-NASS WG V

Zone.

2) The international Redfish survey, coordinated by ICES, covered the Denmark Strait and the Irminger Sea, with three vessels from Iceland, Russia and Germany. The Icelandic vessel would actually also be used as a full cetacean survey platform, as was done successfully in 2001. Unfortunately the German vessel cancelled the survey without reaching the Irminger Sea because of repeated mechanical injuries.

3) The pelagic Norwegian/Russian fish survey had two Norwegian vessels in the Norwegian Sea. The Russian vessel participating to the Redfish survey would also survey in the Barents Sea and in the Norwegian Sea on its way to the Irminger Sea.

The authorities behind the different surveys were contacted and the T-NASS coordinator participated to the ICES Planning Meeting for the Redfish survey (Murmansk, January 2007). Permission was obtained to have two observers onboard the different vessels, except on the MAR-ECO vessel which had only room to house a single observer.

In total, 5,253 nm of whale survey effort were conducted under T-NASS extension, with a total of 288 cetacean sightings made on effort.

Some discussion about the usefulness of the T-NASS Extension ensued at this meeting. In general it was considered a worthwhile addition to the main survey because it provided information on distribution and relative abundance for areas outside the main survey area that will be useful in putting the results of the main survey in context. The usefulness of the data for deriving estimates of abundance is less certain. The effort is generally well distributed in areas that could be designated as strata with relatively balanced coverage (except for the MAR-ECO data). However sightings are few except for minke and sperm whales and likely insufficient to be analyzed separately from the main survey data, and the data must be examined in more detail to see if this is feasible. Acquarone agreed to lead in this effort, and to put a proposal to NAMMCO for additional funding for analysis if that is required.

Some other recommendations were provided to improve the effectiveness of such “opportunistic platform” surveys.

1. Ideally at least 3 observers should be used, one of whom scans the sea with binoculars. 2. It would be very useful if these vessels could overlap in space and time with portions of the main survey, to provide some indication of their relative efficiency. 3. A great deal of other data were collected by these vessels and some of it might be useful in for modelling or other purposes. At the same time the cetacean data may be of interest to the fish researchers. This should be further investigated.

236

NAMMCO Annual Report 2007 - 2008

9. T-NASS ACOUSTIC EVALUATION

9.1 Data collection procedures Although technical problems were encountered on some of the vessels, the acoustic system was generally easy to use and not a heavy burden on the responsible observers. If the data prove to be of value, there were no objections to continuing to have an acoustic programme in future surveys.

9.2 Data collected and planning of analysis The evaluation of the potential of these data is ongoing at SMRU and a decision on further analyses will be made when that is completed.

10. GENERAL EVALUATION

10.1 General T-NASS coordination In discussing the value of a coordinated international synoptic survey, it was necessary to consider what alternatives were available that might be expected to produce similar data. These included uncoordinated or partially coordinated national surveys, or “mosaic” surveys conducted annually and covering a large area over several years. It was concluded that the T-NASS coordination provided many advantages over uncoordinated or less coordinated national surveys. The joint survey planning and commonality of methodology means that the resultant estimates from the coordinated survey can be combined, whereas this may not be possible if the surveys were not coordinated. Mosaic surveys offer many practical advantages in that they can be conducted annually, possibly using the same vessels and observers over long periods, and can be built into annual budgets. On the other hand, the estimates from a mosaic survey apply over several years and must contain additional variance to account for annual variation and long term changes within survey blocks. This additional variance can be great if there are variations in distribution on an annual basis.

The choice between these two modes probably depends mostly on the use of the estimates. In a long-term harvest control system for a single species where estimates must be produced for a specific area on a set time schedule, mosaic surveys may be a viable alternative. However this is not the case for all participants in T-NASS. For some participants it was more important to obtain a snapshot of distribution and abundance of several species, and for this purpose a synoptic coverage offers advantages. In addition temporal changes in distribution by comparison to past surveys can more readily be determined with synoptic surveys.

It was also noted that a synoptic, multi-national survey covering a very large area tended to be more attractive to funding agencies: this was in particular the case for the Canadian survey.

The Working Group concluded that the coordination of surveys under the T-NASS banner had been successful and productive. Problems with the implementation of particularly the ship surveys have been mentioned under section 5 and 237

Report of the Planning Committee T-NASS WG V recommendations for improvement of future large scale surveys are provided within the report as well as collated in Appendix 5. Most importantly, planning the practical aspects of the survey, for example purchasing and testing equipment and training cruise leaders, must be done well in advance of the survey.

There was also a feeling that national interests had dominated in most cases when planning decisions had to be made and implemented. This is understandable since most of the funding came from national research institutes; nevertheless a coordinated survey requires some degree of commitment to the survey as a whole. In several cases, pieces of expensive technical equipment (e.g., “Big Eyes”) were loaned amongst participating countries, decreasing the overall costs of conducting surveys using this equipment.

In this regard it was agreed that further cooperation in coordinating the output from the T-NASS project was of great importance. It was recommended that a primary publication on the planning, conduct and results of the T-NASS, particularly pertaining to general distribution of cetaceans throughout the entire survey area, including the extension areas, be produced as a priority. CODA and SNESSA agreed to participate in this. In addition products for a general audience should be developed (see 10.3-5)

10.2 Feedback after the survey Response to requests from the secretariat or coordinator on updates after the surveys were not always effective in generating answers, which proved very frustrating and led to delays in reporting to different authorities and in building up content for the poster for the ECS.

10.3 Input to website before, during and after Communication with the NAMMCO Secretariat during the survey was sporadic and it was difficult to update the website in a meaningful way. For future surveys this should be improved, as there is considerable public interest in these surveys and funding agencies are interested in seeing the results of their support made public in a timely way. It has continued to be difficult to obtain updates as data compilation and analysis continues. It was hoped that cooperation in this area could be improved.

The NAMMCO Secretariat will continue to maintain a section of the website devoted to T-NASS. It was agreed that, as a starting point, distribution maps for all important species, including sightings from the main T-NASS and extension areas, as well as the CODA and SNESSA surveys, will be developed and posted as a priority. All parties agreed to provide the data to Acquarone in a timely manner.

10.4 Press release It was recommended that the NAMMCO Secretariat develop a press release detailing the conduct and general results of the survey, including maps of the distribution of target species.

238

10.5 Other There were no other points.

11 COOPERATION BETWEEN T-NASS, CODA AND SNESSA

The cooperation between T-NASS, CODA and SNESSA has been positive from the beginning. The provision of survey reports from both T-NASS-associated surveys to this meeting was acknowledged and appreciated. It was also agreed that sightings data would be shared for the production of general interest publications (see point 10.3).

12. T-NASS OVERVIEW AND STATUS

12.1 Overview of effort and data collected: ECS poster A poster presentation outlining the planning, conduct and general results of T-NASS, including a map of fin whale sightings, was presented at the ECS conference in Egmond aan Zee.

12.2 Budget A budget was presented but it could not be updated to reflect actual expenditures, when no feedback had been provided on the actual expenses. The cooperation of national delegates was requested for the update of the budget, so it could constitute usable guidelines/references in future surveys.

13. OTHER ITEMS

The Working Group thanked Genevieve Desportes for her hard work, patience and determination in the face of almost insurmountable adversity in her role as the coordinator of the T-NASS project. Geneviève noted that she had got fantastic support from the ‘successive men’ of the secretariat in this coordination work, Daniel Pike then Mario Acquarone. She also thanked Patrice Simon (DFO Canada) for his enthusiasm for the project and his role in getting Canada to participate. She expressed her appreciation to all who had participated in the planning and conduct of T-NASS, also Christina Lockyer and Charlotte Winsnes from the Secretariat.

Appendix 3 RECOMMENDATIONS FOR THE IMPROVEMENT OF PROCEDURES IN THE ICELANDIC AERIAL SURVEY, INCLUDING MINOR CHANGES TO THE PROTOCOL AND THE DEVELOPMENT OF A PROTOCOL FOR VERY LARGE SCHOOLS

1. Survey altitude should be chosen with regard to the target species. If harbour porpoises are a target, survey altitude should be maintained at 600 ft. Since this altitude appeared to function well for minke whales, it should probably be maintained in future surveys. 2. The secondary fiord strata should be further developed and flown on an opportunistic basis. 3. The protocol modifications emphasizing the collection of abeam declinations should be maintained. 4. The Large School Protocol should be further developed and maintained. 5. The SST sensor is inexpensive, compact, trouble free in operation and potentially provides valuable data for spatial modelling. It should be used in future surveys. However, a way of ground truthing the temperature measurements should be found. 6. A reliable way of finding accommodations in the towns used as bases in Iceland (Isifjorthur, Akureyri, Egilstathir, Hofn) at short notice should be found. 7. The use of high definition video as a secondary platform should be investigated. Pike had the opportunity to use such a system in Antarctica in 2008, and was very impressed by the image quality and our ability to sight Antarctic minke whales on the video. This seems to be far easier than with still photos. Available systems are compact and relatively inexpensive. A single camera could be pointed straight down, or 2 cameras pointed slightly to the side could be used to widen the area covered. Used as a secondary platform, a video system would be independent, provide a clear and unobstructed view of the transect and point, and provide a permanent record that could be reviewed at any time. It would also provide additional information on sea state and ice conditions. If such a system were in use, the flight leader could enter data in flight, as is done during SCANS, American and Canadian aerial surveys.

Report of the Planning Committee T-NASS WG V

Appendix 4 RECOMMENDATIONS FOR IMPROVEMENT OF FUTURE LARGE SCALE SURVEYS

Cruise preparation, including vessels, platforms and equipment (T-NASS)

1. All prospective vessels should be thoroughly inspected by a knowledgeable person before they are contracted. The general condition and seaworthiness of the vessels, as well as their suitability as survey platforms, including autonomy for fuel and water, should be assessed. A certificate of seaworthiness must be provided and the vessel should be tested at sea. 2. Equipment should be ordered and received well in advance of the survey, and should be thoroughly tested in the lab and onboard the vessels before departure. 3. The Cruise Leaders (CLs) should meet together well in advance of the survey, and all equipment should be available for inspection and use at the meeting. This will better enable the CLs to work out problems the equipment and protocols before the survey begins. A pilot/training survey should be conducted with all CLs onboard. 4. All vessels must be prepared thoroughly prepared (e.g. platforms mounted) and equipment mounted before observer training begins. 5. Adequate time must be allocated for observer training before departure. This should include at least one day of class training, and one day of practical training onboard the vessels. 6. Backup equipment, ideally duplicates of all major items, should be purchased for each vessel. 7. The protocol should include detailed instructions on alternative methods in cases of equipment failure. 8. Observers on each vessel should be designated and trained as technical experts on each type of survey equipment, and they should be responsible for onboard repair and maintenance.

Data collection procedures

9. Effectiveness of the “Big-Eye” binoculars seemed to depend on the stability of the platform and the willingness and determination of the trackers to persevere in using them. If “Big Eyes” are to be used special attention should be given to the stability of the vessels and platforms. Further training on the proper setup and use of these would be useful. 10. A better data recording system, possibly using weatherproof computers with touch screens, should be developed and used. The recording system should be fully field tested well in advance of the survey. 11. Consideration should be given to having a dedicated data recorder for the primary platform. 12. There should be frequent meetings of the cruise leader and observers to identify and resolve procedural problems, particularly early in the survey, and 248

NAMMCO Annual Report 2007 - 2008

to receive feedback from the observers. These could be combined with data validation. 13. The cruise leader should regularly review the sightings performance of the observers, with regard to radial distances and angles and species identifications.

Observers

14. If required, survey guidelines and protocols should be provided in a language native to the observer using them. A simplified guide should also be provided to the Captain and crew. 15. All observers should be evaluated after the survey by the CL’s based on specific criteria, and these evaluations should be given to the observer and kept on file for future reference. 16. Observers should be required to provide references and these references should be consulted before contracting. 17. Observers should have a medical examination, including a vision test, before departure. Observers should know their focus settings for binoculars. 18. Observers should be chosen for their observer quality coupled with social skills and dedication for the project 19. A formal meeting should be held at the end of the cruise to gain input from the observers. Another effective mechanism might be to have a suggestion book onboard that can be used at any time.

Survey design

20. The survey design should be based on realistic assessment of available ship time, using the achievements of past surveys in the specific area as a guide. The endurance capabilities of the vessels must also be considered.

Distance estimation Experiment

21. Distance experiments should be conducted primarily as a training exercise at the beginning of the survey and possibly at intervals throughout the survey. 22. The nature of distance experiments should be revaluated and if appropriate a standard method of conducting these experiments be documented.

Communication between platforms conducting a synoptic survey

23. It was recommended that a regular communication schedule be established between vessels in future surveys.

Aerial surveys

249

Report of the Planning Committee T-NASS WG V

24. Lightweight immersion suits (pilot suits) and underwater escape training were recommended to be used in future aerial surveys. 25. The use of high definition video as a secondary platform should also be further investigated. Such systems are relatively inexpensive, compact and have excellent resolution. The use of such a system might make a manned secondary platform unnecessary.

250

NAMMCO Annual Report 2007 - 2008

Appendix 5 SPECIAL MODIFICATIONS IMPLEMENTED FOR ENCOMPASSING HARBOUR PORPOISES

The measures taken in the aerial Icelandic survey to increase survey effectiveness for harbour porpoises were as follows. i. Decrease in survey altitude to 600 ft. This appeared to be successful, in that no problems were encountered in surveying at this altitude, and a large number of harbour porpoise sightings were recorded. The altitude decrease did not seem to detract from the efficiency of the survey for minke whales, in that the effective search area decreased by only 15% compared with 2001. ii. Secondary fiord strata. These strata were added because it was suspected that harbour porpoises might be especially abundant within fiords. They were to be flown on an opportunistic basis, when weather conditions were unsuitable for surveying in other areas. Of the 4 secondary strata designed, only Breidafjorthur (block 2A) and Reytharfjorthur were flown successfully. Winds within the fiords were often stronger than outside, which prevented our completion of the Eyafjorthur stratum. In the limited effort that was completed, it did not appear that harbour porpoises were especially abundant in the fiords. Only one sighting was made in Reytharfjorthur and none in Eyafjorthur. In contrast 11 sightings were made on the additional Breidafjorthur transects so this is likely a high density area for the species. The extra Breidafjorthur effort was incorporated into the survey through post stratification of block 2. No operational difficulties were encountered in flying the sometimes very short fiord transects. Generally this was considered to be a worthwhile addition to the survey. iii. Specialized harbour porpoise observer. Observer P1 had participated in the SCANS II and German North Sea porpoise surveys and was very experienced with this species. Observer P1 recorded 78 sightings of harbour porpoise compared to 38 for observer P2. The total number of harbour porpoise sightings was far greater than in any previous survey. It also seemed that observer P2 increased in effectiveness for this species in response to the large number of sightings made by P1. Therefore this measure should be considered a resounding success. iv. Use of cue counting for harbour porpoises. The intention here was to try cue counting with the dive as a cue, as for minke whales. This was less successful than anticipated. Of the 78 porpoise sightings made by P1, only 17 displayed a definite cue. Many of the animals were recorded as resting on the surface, milling or underwater. It therefore seems that cue counting may not be viable method for this species.

Report of the Scientific WG on Abundance Estimates

ANNEX 2 NAMMCO SCIENTIFIC COMMITTEE WORKING GROUP ON ABUNDANCE ESTIMATES Copenhagen, Denmark, 8 April 2008

1. CHAIRMAN’S WELCOME AND OPENING REMARKS

Chair Øien welcomed the participants (see Section 5). He pointed out that the purpose of this meeting was to examine the early results from the T-NASS 2007 surveys and to discuss plans for further data analysis with special attention to integration with the concurrent CODA and SNESSA surveys.

A summary of the effort achieved and the sightings made during these three surveys is presented in Tables 1 and 2.

2. ADOPTION OF AGENDA

The adopted agenda is given in Appendix 1.

3. APPOINTMENT OF RAPPORTEURS

Acquarone was appointed as rapporteur.

4. REVIEW OF AVAILABLE DOCUMENTS AND REPORTS

Documents that were made available for the meeting are listed in Appendix 2.

Note that all estimates presented in this document should not be used as final point estimates for the surveys unless fully corrected and openly endorsed.

5. FIN WHALES

5.1 Shipboard Iceland/Faroes Pike presented abundance estimates for fin whales from the Icelandic and Faroese survey areas (NAMMCO SC 15/AE/05).

Combined single platform estimates were provided using three degrees of certainty in species identification, and with and without a bias correction for distance estimation. In addition an estimate of g(0) using mark-recapture (or sight-resight) methods was provided. Density and abundance were estimated using stratified line transect methods (Buckland et al. 2001) using the DISTANCE 5.0 (Thomas et al. 2005) software package. Total abundance for the combined platform estimate using the identification certainty classification most comparable to that used in previous analyses and no correction for bias in distance estimation was 20,644 (CV=0.15, 95% CI:15,053-26,540) and 18,846 (CV=0.15) for the bias-corrected data.

The double platform analysis resulted in a mean value for g(0) for the primary 252

NAMMCO Annual Report 2007 - 2008 platform of 0.87 (CV=0.06), which is similar to that estimated for 2001 and a total abundance in the survey area of 23,379 (CV=0.19) using all effort and non-duplicate detections and of 21,341 (CV=0.17) for the equivalent primary platform estimate using effort conducted in double platform mode only, and without g(0) correction.

Estimated abundance is lower (but not significantly so) than the total estimate for 2001 of 24,887 (95% CI:18,186-30,214) (Víkingsson et al. in press). Abundance increased rapidly in parts of this area between 1987 and 2001, and it appears that this increase has ceased.

The basic methodology used was the BT mode with two independent sighting platforms. The analysis carried out is similar to the one used in 2001. The most reliable estimate of distance was chosen among the available as that corresponding to the closest sighting to the abeam position. The estimated bias in distance estimation was applied to the sighting by the primary platform only. Duplicates were identified in the field, as well as later from the information available from the dataset and audio recordings. Single platform estimates were generated for all three sighting classes using all unique sightings from both platforms.

Double platform: The total abundance in the survey area was 23,379 (CV=0.19) using all effort and non-duplicate detections and 21,341 (CV=0.17) for the equivalent primary platform estimate using effort conducted in double platform mode only, and without g(0) correction.

Potential biases • Poor weather and other external factors contributed to reduce coverage in some areas that have had high densities of fin whales in previous surveys. The net effect of poor coverage in some areas most likely will give a negatively biased estimate of abundance. • The least restrictive sighting classification probably results in a positively biased estimate. • The radial distances estimated by the primary platforms were estimated negatively biased by about 9.7% based on the distance experiment conducted at the beginning of the survey, but the bias correction used in the estimate was 13%. However there is some evidence based on comparison of duplicate sightings that suggests that the bias obtained from the distance experiments may have been underestimated in the experiments. • g(0) might be somewhat overestimated because no covariates (other than distance) improved the fit of the conditional detection function.

Multi-year Comparisons There was an apparent increase in fin whale abundance between the 1987 and 2001 surveys. The calculations from the 2007 T-NASS suggest a stable abundance since the last survey.

The Working Group reviewed the analysis and identified several problems and work needed before the analysis could be considered for acceptance. 253

Report of the Scientific WG on Abundance Estimates

• The g(0) calculated for the Primary platform in double platform mode should not be applied without further investigation to the data in combined platform mode. Combining the two platforms into one, which was done at times, indeed results in a different type of effort with more observers and a likely higher g(0). However it is not possible to estimate g(0) when the platforms are combined in this way. The group therefore concluded that the estimated g(0) was applied correctly by the authors. • The choice of the last distance estimate from the trackers was used because it was assumed that there was no responsive movement of the whales and this last distance estimate should be the most accurate. The discussion failed to convince the meeting participants of the validity of this unconventional selection method. It was suggested that a re-analysis be carried out using the initial detection distance standardly used in abundance estimation to investigate the possibility of a bias. • The current species identification confidence index is confusing. The participants felt that another system should be used in the future, while ensuring consistency with previous analyses. • The delegates agreed on the necessity of clarification of the survey procedures which should include a species specific definition of ‘group’. Group size estimates seem to be particularly difficult to assess for pilot whales, leading to difference between observers. In fin whales, however, group sizes are generally small. Group size estimates differed between tracker and primary platforms and it was generally accepted that the tracker estimate is better. Macleod reported that for the SCANS-II survey duplicates were used to determine a species-specific correction factor to be used for bias corrections of group sizes for all primary sightings. It was agreed that Gunnlaugsson would look into this for fin whales.

NOTE ADDED AFTER MEETING: These estimates were revised for presentation to the IWC Scientific Committee in June 2008. The main differences were i) the choice of a more inclusive species identification certainty classification as being most consistent with previous NASS estimates; and ii) no correction for bias in distance estimation by primary observers as the magnitude of this bias (if it exists) remains uncertain. The combined platform estimate using unique sightings from both platforms was 21,628 (CV=0.15). Inclusion of less certain species identification sightings increased this estimate by up to 22%. g(0) was estimated as 0.77 (CV=0.10) for this same certainty classification using the “trial configuration” under the assumption of point independence. The total corrected estimate was 27,493 (CV=0.20).

5.2 Shipboard Norway Øien reported that the Norwegian eastern Barents Sea survey had only 15 primary fin whale sightings. The independent analysis for the Barents Sea alone will not be

254

NAMMCO Annual Report 2007 - 2008 conducted due to the few sightings, but the estimate for the most recent 6 years cycle will be produced within the next year.

5.3 Aerial Greenland In the absence of Heide-Jørgensen, Donovan reported the Greenlandic aerial survey results (NAMMCO SC/15/AE10) presented during the previous week to the IWC RMP meeting (IWC SC/M08/AWMP7).

Two abundance estimates have been produced: c) Line transect with correction for perception bias by mark recapture distance sampling (MRDS). This estimate was not accepted mainly because of the very low number of duplicate sightings (eight duplicates). d) Conventional line transect estimate, which was acceptable for the purpose of RMP.

Suggestions were made at the IWC-RMP Intersessional Workshop for clarification in a future paper to be presented at the IWC Scientific Committee Meeting in Santiago in June 2008.

The analysis was not discussed at length, but the participants agreed that the conventional line transect estimate was acceptable, although the clarifications asked at the IWC RMP Intersessional Workshop should also be provided to the Working Group.

The Greenland fin whale abundance estimate from 2007 was higher than estimates from previous surveys, some were however obtained using a different method and/or carried out in a different period. It was also noted that the survey area did not cover the entire summer range of the feeding stock. The Working Group therefore agreed that there was insufficient information at this stage to reach a conclusion about the rate of increase of fin whales in this area.

5.4 Aerial Canada It should be noted here that all Canadian estimates are preliminary and are given at places without variance. Some estimates have yet to be corrected for biases, including observer bias (Newfoundland and Labrador).

Lawson and Gosselin reported results for fin whales sighted during the Canadian component of the T-NASS (see NAMMCO SC/15/AE/12)

Standard methods were employed and 98 fin whale sightings were made across the survey area, of which only six were in the Gulf of St Lawrence. The preliminary abundance estimate for fin whales is 1,008 (95% CI: 571-1786). Overall, the numbers of fin whales in the Canadian waters were lower than expected. Surveys conducted in the Gulf in 1995-1996 resulted in higher estimates than the 2007 survey; this could be due to: (a) a real population decline, (b) survey bias, and (c) a later arrival of whales in the area in 2007.

255

Report of the Scientific WG on Abundance Estimates

Palka mentioned that the number of fin whales sighted in the SNESSA survey area to the south of Canada (see below under 5.6) was higher than seen in previous years in the same area and month, which also suggests a delayed migration to northern waters.

The Working Group concluded that further refinement of the analysis is required before further discussion of this abundance estimate is conducted.

5.5 CODA MacLeod reported on the CODA area (see NAMMCO SC/15/AE/15).

A total of five vessels participated in the effort which was divided in four blocks. The fin whale sightings were concentrated in the southern blocks (195 primary, 241 tracker, 90 duplicates, and mean group size 1.15).

There were problems in the classification of whales similar to those experienced on the T-NASS ship survey: a large number of sightings were classified as unidentified whales particularly on one of the vessels.

A double platform analysis using Mark-Recapture Distance Sampling methods to generate stratified abundance estimates is planned as a first step. This will be finished by early May to be presented to the annual meeting of the IWC. Estimates will be performed for fin whales alone and for pooled fin and sei whales. It has yet to be decided how to handle the large number of unidentified whales. The detection function developed from the mark-recapture analysis will be used for the density surface models. Dynamic in addition to static variables will be incorporated in the density surface models to generate abundance estimates and investigate habitat preferences.

Plots of perpendicular distances of fin whale duplicates at the time they were seen by the tracker (x-axis) and then by the primary (y-axis), and plots of tracker sightings and primary sightings seen in relation to the vessel at (0,0), both clearly suggested that fin whales move towards the ship.

The Working Group discussed the graphs and concluded that there could be several interpretations: • Fin whales respond to the vessel by moving towards it; • Primary observers systematically underestimate radial distances relative to the trackers; • Primary observers are more likely to spot whales that are moving towards the vessel, relative to those that are moving away from the vessel.

The WG concluded that either attraction to the vessel or systematic underestimation of distance by the primaries would represent a potential bias in standard analysis and that it should be seriously looked at in all fin whale datasets when possible, in particular in the Icelandic-Faroese one.

256

NAMMCO Annual Report 2007 - 2008

5.6 SNESSA Palka reported on the SNESSA surveys, where fin whales were recorded for both aerial and shipboard surveys (see NAMMCO SC/15/AE/8 & 9).

The abundance estimates from the 2007 surveys (both aerial and shipboard) were not available yet but the initial impression was that there were more sightings than in previous years in the same area and time.

Palka reported a new analysis form she was exploring to obtain a corrected abundance estimate for species with few sightings, both in each survey but also over the years. For the aerial surveys (with circle-back) the estimate of g(0) will be pooled over years that have the same aircraft and setup and year is a possible covariate. Then the estimate of g(0) for individual species will be derived by pooling species that have similar detection function shapes. Only groups of <= 5 animals are included in the calculation of g(0) because these are the only groups that are circled on, and thus have the data needed to estimate g(0). This then assumes that groups larger than five are seen with certainty, g(0) is assumed to be equal to1. The group proposed alternative grouping, when some of the species grouped had very different surfacing behaviour as perceived by an observer.

6. MINKE WHALES

6.1 Shipboard Iceland/Faroes No estimate was calculated yet. There are less than 40 sightings in the dataset, which is fewer than in previous surveys. There have been quite large gaps in the effort due mostly to the adverse weather conditions along the coast of Greenland, which has been a high density area in previous surveys. Coverage was also poor to the north and east of Iceland. An analysis is planned even though the estimate might not be as reliable as from previous surveys.

6.2 Shipboard Norway Øien reported that the total estimate for the 1996-2001 survey cycle was 107,000 (cv: 0.14) and for the 2002-2007 cycle was 103,000 (cv: 0.16). Sightings rates in the Barents Sea in 2007 did not appear to be different from previous surveys in the same area.

The CM area (Jan Mayen) shows approximately the same abundance in 2005 as in 1997 (27,000 versus 25,000).

The distributions seems to be similar between the two Norwegian survey cycles, but there was a shift westwards between the synoptic survey in 1995 and the 1996-2001 cycle.

Donovan underlined here the importance of synoptic surveys in interpreting shifts in distribution, while they are difficult to interpret with mosaic surveys.

6.3 Shipboard Greenland 257

Report of the Scientific WG on Abundance Estimates

No documents were provided to the meeting, although it was noted that there were a total of 35 minke whale sightings and this was the most sighted species for the Greenlandic shipboard survey. In a preliminary estimate, a total of 29 unique sightings had been identified, leading to a rough estimate of 4,000 minke whales (Jacob Hansen Rye, pers. comm.).

The Working Group recommended that a proper analysis of these data be carried out as soon as possible.

6.4 Aerial Iceland Pike reported on the Icelandic aerial survey in the coastal area (NAMMCO SC/15/AE/04).

Data analyses were carried out using the DISTANCE 5.0 software packages and stratified cue counting methods (Hiby and Hammond 1989, Hiby et al. 1989, Buckland et al. 2001). Only sightings made in conditions up to Beaufort Sea State (BSS) 3 were included in the calculations. The duplicates were classified (based on cues) in two classes of confidence and the data post stratified. Individual observer performance and bias was also evaluated. The ESW was truncated at 1,200 m. Several covariates were tried in modelling the detection function, but no covariate seemed to improve the fit and the simple half normal model with a single cosine adjustment parameter resulted in the lowest AIC. The cue rate was assumed to be 53 cues per whale per hour, the same rate used in previous analyses.

A total of 71 cues were sighted by the primary and secondary observers at BSS 3 or less. Of these, 9 were cues sighted by both the secondary observer and the primary observer on the same side of the plane (i.e. duplicate cues). The total estimate for the original blocks is 10,680 (95% CI: 5,873-17,121). Post-stratification decreases this estimate by 12%. This estimate may be negatively biased because of visible cues missed by the observers near the plane.

One of the primary observers appeared to be more effective in detecting minke whales than the other and his sighting rate was much higher. Analysis using solely data from this observer only resulted in an estimate of 15,055 (95% CI: 6,357-27,278).

The 2007 point estimate (data from both observer used) is 24% of that from the 2001 survey and the decrease is significant (P<0.05). Abundance was lower in 2007 than 2001 in all blocks but one. The reason for the decrease cannot be determined definitively, but possibilities include population decrease, changes in spatial distribution (i.e. more minke whales outside the survey area) and/or changes in the timing of migration to or from the survey area. The differences in abundance cannot be directly ascribed to changes in survey design or execution.

It was noted that the two-observers estimate is most probably negatively biased and that the single-observer estimate may be unreliable because it is based on a low number of sightings (27). The WG did not opt for either of the two, but accepted the

258

NAMMCO Annual Report 2007 - 2008 analyses as satisfactorily and recommended the acceptance of the estimates by the Scientific Committee.

Reasons for the obvious change in abundance, although not in the general distribution pattern in the area surveyed, compared with the 2001survey were discussed. None of the several possible explanations seem to better explain the dramatic decrease alone.

Víkingsson pointed out that this apparent change in numbers is consistent with recent changes in the ecosystem of the Icelandic continental shelf area perhaps as a result of high sea temperatures in the area. Indications of recent changes include a northward shift in distribution of several fish species, low abundance of sand eel and capelin, and breeding failure in seabirds.

Pike suggested that one way to investigate the temporal change would be by executing spatially smaller surveys throughout the summer. Looking more closely at the Norwegian data in the areas around Jan Mayen to investigate the abundance of minke whales in the area and the trend in distribution and abundance there could also be helpful.

6.5 Aerial Greenland No documents were available to the meeting

6.6 Aerial Canada Lawson and Gosselin reported results for minke whales sighted during the Canadian component of the T-NASS (see NAMMCO SC/15/AE/12)

The uncorrected abundance of minke whales in Canada was calculated to be 997 for the northeast Newfoundland stratum, 394 for the southern Newfoundland Stratum and 2,218 for the Gulf of St. Lawrence and Scotian Shelf areas.

The more extensive survey of 2007 provides a higher estimate than the most recent uncorrected estimate of 1,014 whales (95% CI: 598-1,719) that was obtained by combining estimates from relatively smaller nearshore areas of Newfoundland surveyed in consecutive summers of 2002 and 2003.

Uncorrected estimates for different species, including minke whales, from the 2002-03 nearshore surveys of Newfoundland were not consistently different than the estimates of the larger extensive survey of 2007. Some of the 2002-2003 estimates for smaller cetaceans and minkes were larger than the estimates obtained for the larger area surveyed in 2007, and some estimates were smaller. These differences need further investigation before conclusions can be drown.

6.7 SCANS II Paxton reported on the SCANS survey in the coastal area (NAMMCO SC/15/AE/6 & 7).

259

Report of the Scientific WG on Abundance Estimates

Design-based abundance estimates: the analysis of the shipboard data was based on mark-recapture line-transect methods and the analysis of the aerial data was based on the method of Hiby and Lovell (1998) and Hiby (1999). The study region was divided into 17 blocks, surveyed by seven ships and three aircraft. Estimates of group and animal abundance were obtained for each block and the whole study region. SCANS II minke whale Design-based abundance estimate was 13,281 (CV=0.36) for the shipboard survey (g(0) = 0.55 ; CV=29.2) and 5,333 (CV=0.55, in particular due to only 15 sightings) for the aerial survey, with a total of 18,614 (CV=0.30; 95%; CI: 10,445-33,171). Data from the shipboard survey indicated that minke whale had a tendency of moving away from the trackline.

Model-based abundance estimates: data were analysed using density surface modelling methods (Hedley and Buckland, 2004). Explanatory covariates were used to species density throughout the study region. Using these methods the abundance estimates was 18,790 minke whales (CV=44.0; 95% CI: 7,310-38,085). This analysis approach allows density to be estimated at a much higher resolution (i.e. estimates can be made for smaller regions than blocks) than is possible with a conventional line transect analysis and thus to obtain abundance estimates for regions other than the predefined survey blocks. Thus, minke whale abundance were estimated for the SCANS 1994 study region to 15,594 minke whales (CV=44.5; 95% CI: 6,144- 33,465). For comparison, the same analysis methods were used to analyse the data collected during SCANS 1994, giving 7,785 minke whales (CV=25.0; 95% CI: 5,067-12,753). Paxton underlined the difference between predictive models (using static variables: ‘why are the animals there?’) and explanatory models (using dynamic variables: ‘where are the animals?’) in model-based abundance estimation. These kinds of methods allow producing useful maps and graphs of environmental predictors of the density of whales; they still need to be perfected, though.

Comparison of estimated density surface between 1994 and 2005 indicated changes in spatial distribution between the two surveys, with higher densities in the North Sea, South Ireland, North West Scotland and the western part of the Channel in 2005. The point estimates suggested also an increase in animals in the North Sea in 2005 although the estimates were not significantly different.

The Working Group thanked Paxton for this review and noted the changes in density distribution between the two surveys. It concluded that one interesting use of Model- based abundance estimates would be to help explain temporal changes in the spatial distribution of animals.

6.8 CODA The 15 CODA minke primary sightings were all concentrated in the northern block. These sightings were too few to warrant a separate analysis and should be analyzed in combination with the T-NASS data.

6.9 SNESSA There were 45 sightings of minke whales. Estimates have not been calculated yet, but sightings rates were apparently similar with earlier surveys. 260

NAMMCO Annual Report 2007 - 2008

6.10 Summary Discussion The group discussed at length possible explanations for the decrease in minke whale abundance as observed in the Icelandic coastal area, which did not seem to be compensated by an apparent increase (few estimates have been calculated to date) in abundance (sighting rates) in other surveyed areas. A change in distribution could not therefore be inferred from the surveys data. It was pointed out that the low catches in Norway and Iceland could certainly not explain the decline. The group decided that at least two things could be attempted: • The analysis of the T-NASS Extension minke data in the Norwegian Sea, an area which was not covered by the dedicated survey. A comparison in sightings rate could inform on change in relative densities there. • A spatial analysis of present and past minke data could allow identification of predictors of minke distribution and reveal whether minke whales could have been expected in 2007 in areas which were not covered by the 2007 dedicated survey, e.g., the northern Icelandic blocks. The WG recommended that these two analyses be carried out as soon as possible.

7. OTHER TARGET SPECIES

The data collected can be seen on Table 2

7.1 Humpback whales Greenland aerial Donovan reported on the Greenlandic aerial survey results (NAMMCO SC/15/AE11) presented to the IWC RMP Intersessional Workshop meeting in the previous week (see point 5.3, (IWC SC/M08/AWMP6)).

The approach used in the document was considered in principle correct, but that there were objections to resulting estimate for 2007 of 3,820 (CV=0.51). It was noted that it would be more appropriate to consider only the periods corresponding to the time of the survey when developing the availability bias correction factor. For this reason the IWC RMP Intersessional Workshop asked the authors to present new calculations according to this advice.

The Working Group agreed with the view of the IWC RMP Intersessional Workshop and its recommendation for further analysis.

Iceland-Faroese shipboard/aerial 66 unique sightings out of 81 were seen by Venus and all concentrated in the northwest corner, and it would be probably difficult to generate a reliable overall estimate. No animals were detected by the east coast of Iceland where they have been abundant in previous survey, although the area was very poorly covered. There were also 56 unique sightings in the aerial survey. Pike pointed out that there is an overlap between the aerial and shipboard areas where most of the sightings were made and that this has to be taken into consideration during the analysis.

The estimate from this survey would probably be lower than that from the 2001 one, 261

Report of the Scientific WG on Abundance Estimates due to the difference in coverage alone. An external expert has been contracted to develop the abundance estimates.

Canada Lawson and Gosselin reported results for humpback whales sighted during the Canadian component of the T-NASS (see NAMMCO SC/15/AE/12)

There were 144 sightings for the Newfoundland and Labrador stratum and 83 for the Gulf of St. Lawrence and Scotian Shelf strata leading to an uncorrected estimate of 2,317 animals (95% CI: 1,383-4,149).

SNESSA There were 37 sightings made by the aerial team and 169 from the shipboard. There are good indications that the abundance is much higher than the last survey when only 40 sightings were made.

CODA No humpback whales were observed in the CODA area, nor have they been recorded on previous SCANS surveys.

Eastern Barents Sea Some (11) sightings were made. It seems that the survey was somewhat too early in the season for humpback whales.

7.2 Pilot whales Iceland-Faroese shipboard and CODA No distribution map had been produced at the time.

The NASS conducted since the 1987/89 survey had not provided comprehensive estimates of abundance mainly because of limited coverage. An estimate of pilot whale abundance is a priority for the Faroes and is one of the NAMMCO Council’s requests for advice.

The number of sightings was low in most T-NASS and CODA blocks, mostly concentrated in two blocks, the northern block of the Irminger Sea (45) and the northern CODA block (25). CODA has agreed to combine their data with the Faroese- T-NASS data to produce a common detection function. It was suggested that the Faroese data be analyzed by an external contractor. The Faroese would take the lead on this matter and were investigating the possibility of Macleod undertaking the task.

Canada Lawson and Gosselin reported results for pilot whales sighted during the Canadian component of the T-NASS (see NAMMCO SC/15/AE/12).

In the Newfoundland and Labrador area 10 sightings were made and 43 in the Gulf of St. Lawrence and Scotian shelf area. The uncorrected abundance estimate was 5,833

262

NAMMCO Annual Report 2007 - 2008 whales (95% CI: 3,020-10,867). General comments were made on the difficulty in determining the groups divisions and group sizes for this species.

SNESSA The east coast surveys had sightings of two groups from shipboard survey (coastal) and 20 groups from the aerial survey (offshore).

7.3 Harbour porpoises Iceland aerial The T-NASS survey had 119 sightings which is a very much higher number than in the previous similar survey in 2001. This is likely due to the employment of a specialized harbour porpoise observer on the survey. An external specialist has been contacted to perform the analysis.

Harbour porpoise were a target species for T-NASS and this estimate will represent the first reliable estimate of harbour porpoise in coastal Icelandic waters.

CODA There were only 2 primary and 1 tracker sightings.

SCANS II The abundance estimates within the 1994 survey area were calculated from the 1994 and 2005 data using density surface modelling; the estimates were 345,132 and for 315,027 respectively. Although the overall abundance estimates are not significantly different, there was a big difference in regional abundance between the 1994 and 2005, with lower abundance in the northern North Sea and a higher abundance in the southern North Sea and Celtic Sea in 2005. This has been also inferred from stranding data for the same period.

Canada Fewer animals (n=58) were observed in 2007 than in a smaller-scale aerial survey around Newfoundland in 2002-2003. Similarly, the number of individuals sighted in both the Gulf and Scotian Shelf in 2007 (n=95) was lower than in the smaller-scale aerial surveys in the Gulf in 1995 and 1996 (n=395). The uncorrected estimate is 4,566 (95% CI: 2,242-9,305) animals for all areas in 2007.

Greenland During the shipboard survey 8 animals were sighted (20+ were seen on the market in town) while 46 animals were sighted in the aerial.

The WG recommends that Greenland develops reliable abundance estimates for this species. It also suggests that Greenland coordinates the analysis with Iceland as there is a high degree of similarity between the two surveys (similar methods and one of the same observers). It was noted that the harbour porpoise was the species with the second highest number of sightings (46) after the white-beaked dolphin (58) in the Greenlandic aerial survey.

263

Report of the Scientific WG on Abundance Estimates

SNESSA The sightings were 387 for the shipboard and 131 for the aerial survey. There was no indication of variation in population size, which had previously been estimated to be 81,000.

8. OTHER SPECIES

Sperm whales Iceland/Faroes An evaluation of the acoustic data is in process, which should reveal whether the quality of the data would allow an abundance estimate to be calculated. The visual data would also be analyzed to get an estimate of relative abundance like in previous surveys, although sightings were not very abundant.

Canada There were 22 sightings among all the Canadian survey strata. It may be possible to perform a combined analysis to derive a population estimate.

SNESSA The area is not a typical sperm whale habitat. However eight sightings were made.

CODA In this area 34 primary and 28 tracker sightings were distributed over all blocks but they were more concentrated in the southern one. An absolute estimate of abundance will be calculated using the acoustic data. A visual estimate using conventional distance sampling (at least) will also be generated.

Pike reminded the delegates that many sperm whales were sighted during the T-NASS-extension cruises and that these data have to be included in the analysis.

Killer whales Canada There were a total of 26 individual whales sighted. From current photo-identification efforts there are at least 64 known individuals, and a considerable number of new individuals that are not a part of the catalogue. Thus the total eastern Canadian estimate for killer whales is at least 100 individuals.

Iceland aerial Only 11 sightings were made (including a group of 9 individuals clearly associated with a minke), which is roughly equivalent to previous surveys.

SNESSA No killer whale sightings for this survey and very few in the previous years.

CODA A total of 3 tracker sightings were made for this species.

264

NAMMCO Annual Report 2007 - 2008

White-beaked dolphins Iceland-Faroese shipboard-aerial There are a large number of white beaked dolphin sightings and that there seem to be enough data for further analysis. She noted also that more information on the species was awaited by the SC for being able to conduct a review of the species.

The Working Group recommended the analysis of the data and the production of abundance estimates as soon as feasible.

Canada Lawson and Gosselin reported results for white beaked dolphins sighted during the Canadian component of the T-NASS (see NAMMCO SC/15/AE/12).

There were a total of 617 individual white-beaked dolphins sighted, and preliminary analyses yielded an uncorrected abundance estimate of 1,716 dolphins (95% CI: 893-3,038).

9. T-NASS EXTENSION

Extension data has to be investigated to assess which analyses are worth conducting. The data should be reviewed in the context of the whole T-NASS survey. The data on minke whales in the Norwegian Sea seems particularly interesting to further explore in terms of sightings rate and comparison with earlier surveys in the same area in the framework of the present discussion: where have the minke whales gone.

10. COOPERATIVE ANALYSIS

10.1 Within T-NASS The advantage of using the same person for conducting analysis of the same species was emphasized.

10.2 With CODA and SNESSA Donovan reminded the delegates of their agreement to produce common total distribution maps and a common survey report for the three surveys, task that Desportes and Acquarone had promised to undertake as soon as the necessary data (shapefiles of realized, and possibly planned, effort and of sightings) is made available by the responsible leader of each survey. This should be followed by a primary, peer reviewed publication.

The interest in conducting spatial analysis was reiterated (see under point 6). It was also agreed that spatial modelling be used for fin and humpback whales analyses.

11. PUBLICATION OF SURVEY RESULTS

The NAMMCO SC had previously discussed the advantage of getting the results of such a comprehensive survey published together. The possibility of producing a NAMMCO special Issue had been mentioned. 265

Report of the Scientific WG on Abundance Estimates

Alternatively, Donovan offered to dedicate an issue of the IWC journal to the publication of T-NASS distribution and abundance results. The submission of papers should be completed before the end of 2008 and publication could occur within a year from this meeting pending review.

12. OTHER ITEMS

Donovan asked about the existence of an agreement for the archiving of T-NASS data. He suggested a common archiving location. The IWC offered their facilities for archiving these data in DESS database format. This question should be posed to the NAMMCO SC with special respect to the suitability of this solution.

Palka suggested the data or subsets be submitted voluntarily to the OBIS-SEAMAP database as well.

13. NEXT MEETING

It was agreed that the need for another meeting would be considered as the analysis was progressing.

Palka suggested the group create an e-mail discussion group for questions and discussion related to the analysis of the T-NASS, SNESSA, and CODA survey data. The suggestion was accepted by the group.

14. ADOPTION OF REPORT

Considering the lack of time and the impossibility of being able to have a final accepted report for the meeting of the NAMMCO SC, Desportes ask the participants if it would be acceptable to present a preliminary report to the SC and finalize the report later. The participants would have a chance to comment on a first version of the preliminary report before it was presented to the SC. The report would then be finalized and re-circulated to the NAMMCO SC. This way of proceeding was agreed upon.

The final report was agreed upon by correspondence on 9 July 2008.

ANNEX 3 NAMMCO SCIENTIFIC COMMITTEE WORKING GROUP ON PILOT WHALES Qeqertarsuaq, Greenland, 11 and 13 April 2008

1. WELCOME AND INTRODUCTIONS

The WG convened to discuss draft proposals for a monitoring plan for long-finned pilot whales in the Faroe Islands, developed during the course of internet discussions in the previous few months. The chair of the WG, Christina Lockyer welcomed all members. Apart from the chair, participating members present included Mario Acquarone, Dorete Bloch, Geneviève Desportes, Bjarni Mikkelsen and Gísli Víkingsson. Michael Kingsley, Maria Dam and Thorvaldur Gunlaugsson, also members of the WG, were unable to participate in this instance.

2. ELECTION OF CHAIR AND RAPPORTEUR

Christina Lockyer, was appointed as chair of the meeting, She also acted as rapporteur.

3. ADOPTION OF AGENDA

The agenda was adopted without changes – see Appendix 1.

4. REVIEW OF DOCUMENTATION AND INFORMATION

Documentation is listed in the Appendix 2.

5. DISCUSSION OF THE BACKGROUND AND THE TERMS OF REFERENCE (TOR) FROM COUNCIL AND THE BASIC GOAL OF THE WG

The WG had as Terms of Reference (TOR) and goal, the following extracts from the NAMMCO Annual Report 2006 –

• Extract from NAMMCO Annual Report 2006 vol.I, p.18 - “The SC is requested to develop a proposal for the details of a cost- effective scientific monitoring programme for pilot whales in the Faroes.”

• Extract from NAMMCO Annual Report 2006 vol.II, p.335 - “7.14 Pilot whales 7.14.1 Update on progress since the last ICES SG meeting in April 1996 The Committee last considered this species in 1996, operating under a general request to provide an assessment and advice on the sustainability of Faroese catches. Many of the recommendations for research concerned improving surveys to obtain better estimates of abundance, particularly by expanding

273

Report of the Scientific WG on Pilot Whales

spatial coverage and addressing inter-annual variability. Other recommendations included satellite telemetry to assess movements, and research on social structure, ecology and multi-species interactions. It was strongly recommended that a long-term research and population monitoring strategy be developed related to the Faroe Islands fishery, which should include both longer term monitoring which would help improve understanding of the status of the harvest animals, and short term monitoring to detect more rapid changes as might occur. It was noted that a successful satellite telemetry programme had been carried out in the Faroes, which had provided valuable new knowledge about the movements of pilot whale pods in the medium term (several months) (Heide-Jørgensen et al. 2002, Bloch et al. 2003).

Discussion The Committee was concerned that NASS conducted since 1987/89 had not provided comprehensive estimates of abundance for this species, mainly because of coverage, timing and technical issues. A major priority should therefore be to obtain a better estimate from the T-NASS. The Committee was also concerned that the recommended monitoring programme had not been instituted in the Faroes, although some samples are collected from most grinds on an ad hoc basis. It was therefore recommended that such a program be developed as soon as possible under the auspices of the Committee.

7.14.2 Future work The work on satellite telemetry will continue in the Faroes. The Committee recommended that the most recent tagging data be published. This is a target species of the T-NASS. The Committee noted that there had been no assessment of pilot whales since 1994.”

The WG had available two earlier status reports – SC/5/4 (ICES CM1996/A-6) from the meeting of the ICES Study Group on Long-finned Pilot Whales, held in Cambridge, April 1996, and NAMMCO SC/5/AE 3 on the abundance estimate of N. Atlantic pilot whales from the NASS-95.

SC/5/4 noted that in 1993 the Study Group recommended the following:

274

NAMMCO Annual Report 2007 - 2008

However, no additional work had been undertaken by 1996, and there was nothing new to report. Bjarni Mikkelsen brought attention to a 2000 paper on genetics and water temperature (Fullard et al., 2000).

With respect to pollutant studies it was reported that

The report recommended that satellite tagging should be developed and carried out to follow movements of pilot whales in the Faroes area.

The report referred to the abundance estimates derived from NASS89 and earlier for the eastern N. Atlantic.

The report presented information on prey abundance and distribution correlation 275

Doc. NAMMCO SC/5/AE 3 presented abundance estimates from the NASS95 survey, and these are extracted from this document and presented below in Table 1. The overall abundance is just under 215,000 animals (.95 CI ca 130,000 – 355,000). The new data from the TNASS should be prioritised to produce updated abundance estimates as soon as feasible and surveys should be repeated at regular intervals in order to maximise the outcome of any monitoring programme adopted.

Table 1. Abundance estimates by block (seen in chart to right). Figures in parentheses are % cvs.

The lower estimates compared to earlier NASS89 surveys was only partly explained by different areal coverage, and comparison on just similar Faroese blocks indicated lower – but not significantly - abundance in 1995 (ICES CM1996/A-6).

NAMMCO 1997, in commenting on the work of the ICES Study Group of 1996, reported that apart from status and assessment, sustainability of catches around the Faroes was a concern.

The Recruitment area for pilot whales which are coastal could be much further afield. The use of tagging could be useful here although tagging in other areas than the Faroes would be desirable. Genetics was useful in determining population structure, but presently this told more about intra- and inter-school relationships more than overall population.

276

NAMMCO Annual Report 2007 - 2008

Historic catches could be used to tell about sustainability (Bloch et al., 1990; Bloch, 1994; Bloch and Lastein, 1994).

Gísli commented that while genetics might not tell very much, new technology on relatedness – Hans Skaug et al (2008) was a promising tool.

The WG discussed the TOR and its interpretation. It concluded that, although this was not expressed directly in the TORS, the aim of the monitoring programme was to assess the continued sustainability of the Faroese catch and that “there should be both a long-term and short-term monitoring directed to determining the continued sustainability of the Faroese catches”.

6. DISCUSSION OF METHODS AS COMPONENTS FOR A SAMPLING AND MONITORING PROGRAMME ALREADY PRESENTED, AND ANY NEW METHODS, PARTICULARLY WITH REFERENCE TO RELEVANCE TO THE TOR.

There is already a basic sampling programme in existence (with full coverage of nearly all catches today) and catch statistics on schools in the grindedrap since 1584 (in blocks of time) and also grinds and sampling since July 1988 – January 2008 (Dorete Bloch’s paper SC/15/PW4). Dorete’s doctoral thesis (Bloch, 1994) has new results and papers on the pilot whale catches. Otherwise there is nothing really new. Samples collected since the 1986-88 programme have not been worked up, so that ca 20 yr have elapsed since any analyses have been done, and here is only sporadic new information.

Information on pollution analyses was provided by Maria Dam via the e-mail discussion group and in a table of costs information, ca 200,000 DKK is available for 2008 analyses of POPs in the Faroes, Iceland and Greenland for a joint project.

The WG considered document SC/15/PW7 introduced by Bjarni Mikkelsen on recent developments in satellite tagging in the Faroes. Whales are not easily accessible for tagging because scientists compete with the locals for suitable target schools of whales. The pod should be intact when released after tags have been applied. Tags have been available since 1997. Tagging of 4 whales in 2000 showed that the stability of a pod may not be strong because the tagged whales dispersed. The shelf life of tags was not good as the battery runs down.

In 2004 tagging was possible again and 7 whales were tagged. Cooperation with local people is essential.

There are now 9 tags available for deployment, but scientists may have to wait many years for another good opportunity to deploy. Duration of the tags has been at best 133 days. Most range only from several to only few days. In 2004, the tagged group did not disperse, except from one animal leaving the group, so different pod behaviour pattern from previous efforts.

277

Report of the Scientific WG on Pilot Whales

There is a continuous development of smaller and more efficient tags. This is important because social behaviour is very important within the pod so tags must be discrete. Loss and damage of tags is believed to be due to such social body contact. Pilot whales often log at the sea surface , so possibilities for uplinking of satellite data are good. Other oceanographic data can also be collected by satellite tags – e.g. sea temperature and salinity, etc. but these greatly add to the cost. Wildlife Computers provide tags at present but SMRU tags that incorporate other data gathering are much more expensive. Minimising the effect on the animals is important as stability of the whale group is important.

A key problem with telemetry is the unpredictability of how and when the method can be deployed. The method is potentially valuable for monitoring stability and dispersion of pods but also how far animals venture. So far all tagged whales have predominantly moved to northeast of Faroes towards Norway in the Faroes-Shetland channel and northward. Southern Norwegian Sea appears to be a home range for the tagged pods from the two tagging events. However it was noted that these were conducted about the same time of the year (late summer) and taggings at other times of the year might give different results. It is important to continue to determine if the catchment area for recruitmet is mainly from N.E.of Faroes towards UK and Norway or also from the west towards Iceland. It was suggested that perhaps Iceland and Faroes could cooperate in a tagging programme? This might also tell where animals came from as well as where they go to.

Diving depth can be monitored from the tags. Maximum dive depth was 848m, and within every 24 hr period there are always dives to below 600 m. This may indicate foraging behaviour perhaps for squids. Dive behaviour may thus be linked to potential diet. Swimming speed is 1-5m per sec.

In a final evaluation of the method, it was noted that it would be most valuable if the tags would remain on the animals for up to a year.

The WG considered the recent information on pilot whale abundance from the TNASS and Abundance Estimate WGs, and considered the report of the Abundance Estimate WG SC/15/AE/13. No distribution map has yet been produced. It was noted that sightings from both TNASS and CODA surveys were limited and thus data was agreed to be combined for both surveys. It was advised that an external contractor be sought to do the analysis for abundance. The WG noted that there is a request from NAMMCO 16 (NAMMCO/16/MC/4, item 3.8.4) for a priority assessment of pilot whales on completion of TNASS.

The WG then discussed SW/15/PW3 which provided a summary table of ideas on methods that could be employed as part of a monitoring programme to collect relevant information. This had been compiled as a result of e-mail correspondence within the WG. In particular emphasis was placed on the goal of the methods and what useful information would be gathered that could contribute to the monitoring of sustainability of catches. It was recognised that this was a first step and that details of such a 278

NAMMCO Annual Report 2007 - 2008 sampling and methods part of a monitoring programme would require considerably more effort from the WG at a future meeting to develop a meaningful, feasible and coordinated programme.

It was also recognised that this only provided input to the next important stage where regular integration of data, results and analyses would be required in reports to the authorities with recommendations on the status of the catches in relation to the population.

Sampling and Methods • Catches - numbers of schools, individuals and date and place • Catch composition by total body length, age, sex and reproductive status – biological sampling of teeth, ovaries, etc. • Tagging, parasites, and contaminants for determining catchment area and recruitment • Genetics, contaminants, internal parasites (linked with stomach and gut sampling) for population structure and relatedness • Population parameters and dynamics – biological parameters, reproductive rates and growth using teeth, ovaries, etc. • Replacement and sustainability – population dynamics – trends in biological parameters • Environmental parameters – sea temperature, salinity, prey abundance, contaminants in relation to spatial distribution. • Health and body condition – contaminants, body fat (blubber thickness, girth) – linked to growth and reproduction, virology, (stomach contents not necessary). • Surveys and assessments are required ideally at regular intervals - e.g. 5-10yr (usually every 6 yr in Iceland) to detect trends in abundance. Indices in abundance need to be estimated so that all surveys can be meaningful.

Environmental factors are important as they influence the behaviour and health of whales. Many studies could indicate “alarm bells” when changes were imminent or taking place and initiate additional specialist studies. Contaminants may disturb the health of the population and its fecundity. Parasites may be labour intensive to sample and hand-in-hand with stomach and gut sampling which is not essential.

7. COMPARISON OF THESE METHODS WITH WHAT SUCCEEDED IN PREVIOUS RESEARCH AND MONITORING PROGRAMMES – NOTES AND TIPS

The WG briefly examined the work of the Faroese 1986-88 research progamme reported in the IWC Special Issue on pilot whales (Rep.int.Whal.Commn (Special Issue 14). The following were noted: • Environmental monitoring in relation to whale distribution could be very interesting for very long-term monitoring, as such had proved enlightening

279

Report of the Scientific WG on Pilot Whales

for other species such as minke whales and harbour porpoises in explaining redistribution (data presented at this SC meeting). • Focus on reproduction should be in females – especially age at sexual maturity, examination of ovaries for ovulation/pregnancy, presence of foetus (with allowance for missing of small fetuses and timing of the breeding season). • Numbered plastic tag duplicate series could be essential to identify separated body parts during the grind flensing stage when sampling. • Body condition – blubber thickness and girth – simplify sampling and measurement as much as possible by selecting just one representative body site.

8. DISCUSSION OF ANALYSES THAT COULD BE UNDERTAKEN ON EXISTING DATA NOW

The following were considered important and to be undertaken before the start of any monitoring programme: • Calculation of indices of abundances from previous NASS surveys – 87 and 89, 95 and 2001, as well as 2007. • Full documentation and statistical analysis of historic catch series – including length / skinn composition of pods – oscillation in mean lengths over time may be inherent or correlated with factors external – although not surface temperature (for skinn values, see Bloch and Zachariassen, 1989). A full analysis is already planned to be undertaken by Dorete Bloch in collaboration with Lars Witting.

9. DRAFTING OF A MONITORING PACKAGE THAT INCLUDES BASIC ESSENTIALS WITH RELATIVE COSTS, AND DESIRABLE BUT NON-ESSENTIAL ADD-ON PROJECTS – TO BE PRESENTED TO THE SC FOR CONSIDERATION

Sampling component Refer to Annex 1 for a summary of the methods and sampling possibilities suggested.

Reporting and evaluation component • Catch statistics are reported annually to national authorities today, and it is desirable to report also catch composition annually. • Catch information and catch composition data and analyses should be submitted annually as part of the NAMMCO Progress report and presented to the NAMMCO SC. • Survey plans should be announced to the NAMMCO SC, and on completion, reported on together with the final abundance assessment to the NAMMCO SC for evaluation, as has commonly been the practice in NAMMCO. • Reporting of analyses on population biology and health and other sample- based studies should be undertaken at regular intervals – not necessarily annually. 280

NAMMCO Annual Report 2007 - 2008

• New information with assessment results from surveys and analysis of catches in relation to abundance should be submitted to perhaps an international study group (e.g. standing NAMMCO WG on pilot whales) after each new results from a survey have been obtained to provide a more comprehensive integrated status report which can be evaluated expertly. • All pilot whale reports evaluated by the NAMMCO SC should be submitted to national authorities.

10. CONCLUSION AND REPORT

It is clear that another WG meeting will be required to finalise the monitoring programme proposal with detailed costs. Timing could be in early July 2008. The WG will need to detail sampling strategy and advantages of different methods together with costs, and possibly collaborate with the Faroese in advising on any revisions of their existing sampling protocol for the authorities during grinds. However, any final proposal must be considered by the SC and will thus not be available for the Council meeting in 2008. However the Faroes will not be able to begin a sampling and monitoring programme before 2009, since it has to be approved by the Council.

Many of the recommendations for research concerned improving surveys to obtain better estimates of abundance, particularly by expanding spatial coverage and addressing inter-annual variability. Other recommendations included satellite telemetry to assess movements, and research on social structure, ecology and multi-species interactions. It was strongly recommended that a long-term research and population monitoring strategy be developed related to the Faroe Islands fishery, which should include both longer term monitoring which would help improve understanding of the status of the harvest animals, and short term monitoring to detect more rapid changes as might occur. It was noted that a successful satellite telemetry program had been carried out in the Faroes, which had provided valuable new knowledge about the movements of pilot whale pods in the medium term (several months) (Heide-Jørgensen et al. 2002, Bloch et al. 2003).

Discussion The Committee was concerned that NASS conducted since 1987/89 had not provided comprehensive estimates of abundance for this species, mainly because of coverage, timing and technical issues. A major priority should therefore be to obtain a better estimate from the T-NASS. The Committee was also concerned that the recommended monitoring program had not been instituted in the Faroes, although some samples are collected from most grinds on an ad hoc basis. It was therefore recommended that such a program be developed as soon as possible under the auspices of the Committee.

7.14.2 Future work The work on satellite telemetry will continue in the Faroes. The Committee recommended that the most recent tagging data be published. This is a target species of the T-NASS. The ommittee noted that there had been no assessment of pilot whales since 1994.”

Report of the Scientific WG on Pilot Whales - ADDENDUM

ADDENDUM NAMMCO SCIENTIFIC COMMITTEE WORKING GROUP ON PILOT WHALES Copenhagen, Denmark, 7-8 July 2008

1. WELCOME AND INTRODUCTIONS

Lockyer welcomed the convened Working Group (WG) Members and gave a brief introduction to the house and facilities including schedule and catering plans. She then invited them to introduce themselves. Present were: Mario Acquarone (NAMMCO), Dorete Bloch (Faroe Islands), Maria Dam (Faroe Islands), Geneviève Desportes (Faroe Islands and Scientific Committee Chair), Thorvaldur Gunnlaugsson (Iceland), Michael Kingsley (Greenland), Christina Lockyer (NAMMCO) – see Appendix 4.

2. ELECTION OF CHAIR AND RAPPORTEUR

Lockyer was elected Chair and Acquarone rapporteur.

3. ADOPTION OF AGENDA

The Agenda was adopted with the addition of item “10. Other business”.

4. REVIEW OF NEW DOCUMENTATION AND INFORMATION, INCLUDING THE WG REPORT FROM APRIL 2008 AND SC REPORT EXTRACTS

The Chair presented the documents sent out with the invitation (Appendix 2). No additional documents were submitted to the group.

Lockyer underlined that after the report from this meeting is circulated to and approved by the Scientific Committee (SC) it will be presented to Council (2-4 September 2008, Sisimiut).

5. DETAILED SCIENTIFIC EVALUATION OF COMPONENTS OF MONITORING PLAN PRESENTED IN ANNEX 3 OF THE APRIL WG REPORT (SC/15/11)

The WG had as Terms of Reference and goal, the following extract from the NAMMCO Annual Report 2006: “The SC is requested to develop a proposal for the details of a cost-effective scientific monitoring programme for pilot whales in the Faroes.” (Extract from NAMMCO Annual Report 2006 vol. I, p.18)

The WG had interpreted the aim of the monitoring programme as being to assess the continued sustainability of the Faroese catch and that “there should be both a long- term and short-term monitoring directed to determining the continued sustainability of the Faroese catches” (SC/15/11).

288

NAMMCO Annual Report 2007 - 2008

The Chair asked the Members if there were any comments on the report from the April 2008 meeting of this working group (SC/15/11). There were no comments.

It was suggested beginning the evaluation by a table on which Monitoring activities were divided from Research activities. It was further suggested that Monitoring should further be divided into “monitoring according to the requests from Council” and “additional monitoring”. Research could accordingly be divided into research that would help the monitoring requested from Council and other research. There would also be a monitoring section on “supporting activities”. The WG accepted this as a way forward (Table 1).

Table 1. Proposed activities of a monitoring programme

The WG used Appendix 3 (extracted from the Report of the first meeting of the WG, presented to the NAMMCO SC15 (SC/15/11) – Proposal for sampling and methods in a monitoring programme for sustainability of pilot whale catches of the Faroe Islands) as the basis for discussion of priorities in the monitoring plan. The following items constitute the most important and essential of such a plan and are summarised in Table 1 above. 289

Report of the Scientific WG on Pilot Whales - ADDENDUM

The following paragraphs expand and discuss in detail the items listed in Table 1.

Commission requests The following items represent the basic requirements for a monitoring programme that would fulfil the request for monitoring by Council.

A. Abundance surveys The WG recommended that the abundance surveys provide both indices of abundance and absolute abundance. Surveys should be carried out at least every six years. Abundance surveys are the cornerstone of stock assessments.

The following points illustrate monitoring-specific required research:

A.1: Review of past data - A reviewed analysis of past surveys, specifically NASS data (Faroese-Icelandic and 1987 and 1989 Spanish data) developing indices of abundance in different areas, would produce essential baseline data against which to compare new results to produce trends in population size. This has already been endorsed by the SC (SC/15/11).

A.2: Survey methods – the effectiveness of methods used in the recent T-NASS survey with respect to this species should be verified. Pilot-whale-specific survey design and methods (e.g. timing of the survey, height of the observation platform and recording of school size) should be refined and included in future surveys.

A.3: Area of stock distribution – The definition of a survey area of relevance to the assessment of the exploited stock(s) should be verified from information on population structure obtained e.g. by a tagging programme. Tagging is instrumental to understanding distribution and movements and as a base for survey design. A number of options in the choice of tags were discussed. It is preferable to deploy a larger number of smaller simple tags rather than fewer more complex instruments for the same cost. Among the possibilities, not mutually exclusive, the WG elected SPOT5 satellite tags (cost 12-14,000 DKK, adapted for harpoon deployment) for short term detailed movement of individuals, and sub-dermal microchips (or a modified, recoverable “Discovery” tag) for longer term mark-recapture and movement studies, as the most promising options. Tags should be deployed both in the Faroes and elsewhere in the North Atlantic according to an experimental design to be specifically developed. Natural marks, such as genetic markers are an alternative and genetic samples should be collected from all available catches to keep open the possibility of a DNA register. Photo- ID does not appear to be a feasible alternative for north Atlantic pilot whales owing to the large population size, paucity of natural marks, absence of historical photograph data and the logistic difficulty of photographing animals taken in the drives.

The following additional items are optional research topics that complement, but are not essential, for the development and assessment of the monitoring programme:

290

NAMMCO Annual Report 2007 - 2008

A.4: Genetics – Relatedness (Skaug, H. et al. 2008. Relatedness of North Atlantic fin whales; an update. IWC SC/M08/RMP WP3) based on biopsy sampling activities run in parallel with the tagging programme and integrated by grind- sampled biopsies could provide information on the genetic structure of the population, thus defining relations in and between pods and delineating stocks. The availability of tissue samples from pilot whales in other areas and previous periods for specific genetic analysis could be investigated and to this end it would be worth exploring existing tissue banks (e.g. in the Faroes and in ASCOBANS member countries). Continuance of the Faroese tissue bank is encouraged. Alcohol as a medium for genetics-directed sample storage, rather than freezing at -80oC, was suggested.

A.5: Life table – Age-specific knowledge of life history parameters could in the long term form a basis for population modelling as an alternative check on the sustainability of the harvest. However, the compiling of such a table is labour intensive and the WG was unable to accord this activity a high priority.

B. Catch statistics The most basic information used in management is numbers caught and age by sex. These are routinely collected for fish stocks. The present official reporting system gives the information of date, number of whales, skinn (a measure for weight), length and sex of individual whales caught in the Faroe Islands. In order to determine whether the catch is sustainable it is, however, necessary to know the individual age and sex, to be able to determine whether changes in age distribution occur. To meet this requirement it is necessary to do some additional sampling and analyses beyond the monitoring already in place. Teeth (lower jaws) should be collected for age determination alongside the numbers and sex of the whales. The design of appropriate sub-sampling schemes for recording and analysis of data would be a part of the finalisation of a monitoring plan. The WG recommends the continuation and improvement of the current catch statistics recording along with jaw collection.

The following points illustrate monitoring-specific required research:

B.1: Analysis of existing catch series – An in-depth analysis of existing long-term catch series with associated data on size and other biological details is an excellent starting point for a demographic study through a catch- at–age-and-sex data table (see Agenda item 6), below).

B.2: Intensive short-term catch sampling – Design of a long-term monitoring plan will need better information on the within- and between-year variability of the data to be recorded. A short-term intensive sampling programme of sex and age distribution data over a three year period is necessary to assess the present within- and between-year variabilities and to compare them with those measured under the 1986-88 sampling programme. Such analyses will facilitate the design of a solid, cost-effective and long-term monitoring programme.

291

Report of the Scientific WG on Pilot Whales - ADDENDUM

During this intensive sampling, it would be cost-effective and valuable to take additional samples that may be used to shed light on causes for possible demographic changes. This includes pieces of meat and blubber, ovaries, mid- girth measurement, and lateral blubber thickness, and from some individuals blood, kidney and liver samples. These additional samples will then be used for studies of contamination, condition, health and reproduction, including also the potential negative effects of contaminants on the whale organism. (See further explanation and discussion below under items D.-F. and I.).

C. Reporting Progress, results and conclusions from the monitoring programme (including all survey plans and analyses) are to be reported and submitted for review to the NAMMCO SC.

Additional topics The following items represent additional components in a monitoring plan that are important for additional interpretations of items A. and B. (above), though not strictly essential for a basic monitoring programme, are recommended because they represent great added value for a minimal outlay of cost and manpower if undertaken alongside item B.

D. Catches Currently date, locality, numbers, sex and size (length and skinn) are routinely collected for all grinds. It is recommended to continue the recording of these data.

E. Contaminants There is currently (1996-2008) a programme for contaminant analysis of the Faroese pilot whales under the auspices of AMAP (Arctic Monitoring and Assessment Programme). Periodic analyses during the past three decades represent valuable data on contamination of pilot whales in Faroese waters. In this respect the Faroese pilot whales are one of the very few species of cetaceans with a long history of contaminant concentration measurements. It is recommended that the current programme is intensified and integrated with the new monitoring programme. See also additional remarks under item F. Reproductive status below.

F. Reproductive status Reproductive status, especially of females (state of maturity, age at sexual maturity, pregnant, lactating, etc.) is valuable for providing a picture of the overall production and reproductive health of the population. The collection and examination of ovaries and presence/absence, length and sex of a foetus should be included in the programme. The following additional item is an optional research topic that complements, but is not essential, for the development and assessment of the monitoring programme:

E – F.1: Effect of contaminants on reproduction – The long history of sampling and analyses of contaminants in the Faroese pilot whales gives the possibility of examining the effect of pollutants on reproduction. This also emphasises the 292

NAMMCO Annual Report 2007 - 2008 added value of continuing the contaminant studies.

G. Health The general health status of this population has not been monitored, and is unknown, but may be important in explaining future changes in stock status. A possible method is analysis of blood samples. (e.g. Tryland, M. et al. 2006. - Serum chemistry of free- ranging white whales (Delphinapterus leucas) in Svalbard. Veterinary Clinical Pathology 35(2):199-203). However it is unknown what pathological conditions this population is subject to, or how to detect them. Therefore any health status monitoring would be dependent on the following research activity in the early stages of the developing the monitoring programme:

G.1: Health – A general examination of a sample of animals taken in the harvest for pathological conditions, including disease and parasite infestation, in order to determine which pathological conditions may be frequent and significant and how to detect them reliably and cheaply.

H. Condition Body condition as distinct from general health (above) is an indication of short term feeding success. In 1986-1988 (Lockyer, C. 1993. Seasonal changes in body fat condition of Northeast Atlantic pilot whales, and their biological significance. Rep. int. Whal. Commn – Special Issue 14: Biology of Northern Hemisphere Pilot Whales, pp.325-350), girth and blubber thickness were used as indicators of body fat condition. The most useful measures were girth (G3) and lateral blubber thickness (probably body site L3 is the most practicable). It is recommended that these are collected routinely along with length, when they may be collected with little extra effort.

The following additional item is an optional research topic that complements, but is not essential, for the development and assessment of the monitoring programme:

H.1: Spatial analysis of distribution data – In the long term, this should be considered especially in view of NAMMCO’s commitment to an ecosystem approach to management, but is of low priority relative to a monitoring programme.

Supporting activities These items listed in Table 1 are of low priority to the establishment of a Faroese monitoring programme. Items I. and J. could be valuable in the longer term for obtaining pilot whale data and samples from a wider geographic area that could augment Faroese data and analyses. Item K. addressing reviews of other cetacean management plans, could provide useful reference and guidance on future management of the pilot whale. Further discussion of some of these points follows later.

6. ANALYSES THAT COULD BE UNDERTAKEN ON EXISTING DATA

293

Report of the Scientific WG on Pilot Whales - ADDENDUM

• It was (item J., Supporting Activities in Table 1) suggested recommending approaching organizations that might have pilot whale samples in their tissue bank (e.g. in ASCOBANS countries). It was suggested posting an announcement for existing tissue banks on MARMAM. The WG recommended that the Secretariat investigate the availability of genetic samples before the next NAMMCO Scientific Committee meeting (SC16) with a view to an extensive study involving samples from sources other than Faroese.

• The WG recommended the completion of the demographic analysis based on the historical Faroese catch data (see Research Activity 2a)).

• The WG further recommended producing indices of trends of abundance by areas based on past surveys (see Research Activity A.1)), specifically NASS data (Spanish data from 1987 and 1989, and not only Faroese-Icelandic data) before the next NAMMCO Scientific Committee meeting (SC16).

• The WG finally recommended the initiation of an intensive 3 years’ sampling programme (see Research Activity B.2)) in order to investigate the variability of the parameters to be included in the long-term monitoring programme.

7. TENTATIVE COSTING OF RECOMMENDED COMPONENTS, MANPOWER NEEDS AND POTENTIAL FUNDING CHANNELS

All prices must be taken with reservations. • A preliminary budget covering expenditures for sampling, age determination and reporting results is 825 DKK per individual whale, including manpower, for an initial three years’ intensive sampling programme as outlined in research activity B.2 and reporting item C. This budget is calculated from the annual average take of 6.3 grinds consisting of 150 whales each and in total 1,000 whales per year. Basic funding for this component will originate from Faroese government sources. Additional funding sources will have to be identified.

• Surveys: synoptic ship-based sighting surveys should be carried out at intervals of not more than 6 years (about 2 M DKK in 2007, including analysis). Manpower needs will depend on the survey method of choice and on the number of simultaneous working platforms. In the previous NASS surveys funding was obtained through the Faroese government sources, Nordic Council of Ministers, Oil Companies and private funds.

• Other tissue sampling: in the calculated costs for the intensive three years’ sampling for age determination in item a. above (see also Item B.2)), additional measurements and sampling including soft tissue like foetus, meat, blubber, liver, kidney and ovaries were included. The inclusion of these additional components over and above mere catch statistics, sex and age is 294

NAMMCO Annual Report 2007 - 2008

estimated to increase the total basic sampling cost per whale by 6 % from 775 DKK to 825 DKK. Given the importance of these tissues for monitoring and/or study of other impact factors and individual body condition indices, it is considered a highly cost-effective strategy to expand the scope of the sample and data collection. Thus sampling of all catches, strandings and opportunistic sources (live sampling) should be encouraged. Presently there are only data on costs and manpower needs for the part of the supporting research activities that includes monitoring of pollutants like PCBs, pesticides and heavy metals (see Item E). The monitoring of PCBs and pesticides in blubber, and heavy metals like mercury and cadmium in muscle, liver and kidney has been estimated to amount to 5,700 DKK per whale for a total of 50 individuals. This includes sample preparation, analyses, data assessment and reporting. This estimate also includes the determination of stable isotopes of carbon and nitrogen which are used for food-web indications.

8. IMPLEMENTATION OF A REPORTING AND EVALUATION SCHEME FOR THE MONITORING PROGRAMME – NEED FOR A STANDING WG?

The WG recommended that a report on the monitoring programme be presented to NAMMCO every SC meeting as a part of the Faroese National Progress Report. Similarly the Group also recommended that a review of the initial intensive sampling programme be carried out at the latest within four years after its start in order to allow for the timely definition of the long-term monitoring programme. In particular, abundance survey planning and results should be presented in time before the annual meeting of the NAMMCO SC in order to allow for a thorough scientific review.

The WG noted that there is currently an outstanding request for the results from the completed Icelandic minke whale research programme to be presented to the SC for review. The WG considered that after evaluation by the SC, it could be useful to investigate which components of this Icelandic programme were potentially relevant to the pilot whale monitoring programme.

In view of the magnitude of the task of reporting, reviewing and adjustment of the pilot whale monitoring programme the group reiterated its previous recommendation that a standing working group be created. This was endorsed at the previous SC meeting (SC/15/11).

9. RECOMMENDATIONS ON A FUNCTIONAL MONITORING PACKAGE

The WG emphasised that the absolute minimum requirements for a monitoring programme would be the implementation of items A., B. and C. including the necessary preliminary research activities of Table 1. For reasons of cost effectiveness and added research value, the WG also recommended that items D., E., F. and H. (together with research activities) be seriously considered as part of a complete

295

Report of the Scientific WG on Pilot Whales - ADDENDUM package. Items G. and H.1 are interesting in the long term but not a priority. Supporting activities (items I. – K.) require further consideration by the WG.

10. OTHER BUSINESS

It was suggested drawing up a wish list for data collected in case of strandings or takes in other areas than the Faroes (see Table 1, supporting activity I.). The WG agreed to continue this matter by correspondence and develop a list that could be circulated along with the Secretariat’s enquiries regarding availability of tissues in tissue banks and institutions (see Table 1, supporting activity J.).

The WG recommends that an “Alert Hotline” channel of communication for pilot whales be instigated whereby strandings – live and dead – could be quickly communicated to interested researchers so that opportunistic sampling relevant to the monitoring programme could be made in any North Atlantic area. The internet MARMAM site ([email protected]) could be instrumental in setting this up.

This report was accepted in a preliminary version on 8 July 2008 and finalised on 14 July 2008.

1. INTRODUCTION

This report summarises Faroese research on cetaceans and pinnipeds conducted in 2006 and 2007. Since 1984, the main bulk of research on marine mammals in the Faroes has been conducted by the Zoological Department of the Faroese Museum of Natural History, which in 2007 became part of the newly created Environmental Agency. Additional studies are carried out by the Faroese Fisheries Laboratory, the Food and Environmental Agency of the Faroes, and the veterinarians involved in whaling.

2. RESEARCH

2.1 Species/Stocks studied Cetaceans Fin whale (Balaenoptera physalus) – hunting statistics Sperm whale (Physeter macrocephalus) - stranded animals Bottlenose whale (Hyperoodon ampullatus) – stranded animals Pilot whale (Globicephala melas) - landed animals Bottlenose dolphin (Tursiops truncatus) – landed animals White-sided dolphin (Lagenorhyncus acutus) - landed animals Harbour porpoise (Phocoena phocoena) – stranded animal Grey seal (Halichoerus grypus) – tagged animals

2.2 Field Work (e.g. sighting, tagging, scientific sampling) Bottlenose whale In 2007, three bottlenose whales stranded in Sandvík and had to be euthanized. The Museum got full samples, see Table 3. For clarification, full samples include: total length, weight (when possible), sex, and lower jaw containing the teeth for ageing, ovaries/testes, stomach, samples of muscle, blubber, kidney, and liver. If the animal is pregnant, the same measurements and samples are taken of the foetus.

Pilot whale Sex, skinn values and total body length in cm have been recorded from nearly all pilot whales caught in 2006-2007 with kind assistance from the district police and the men

303

Faroe Islands – Progress Report Marine Mammals evaluating the whales. The museum is notified every time a whale drive occurs and explores every opportunity for using the pod for satellite tagging studies. The museum has started a small-scale sampling programme from the pilot whale drives, with four drives being sampled in 2006 and one drive in 2007, see Table 2. The sampled schools are those which are easy to reach in time and when enough assistants are available. Full samples are taken from 20 animals on a random basis.

White-sided and bottlenose dolphins Sex and total body length in cm have been recorded from nearly all white-sided and bottlenose dolphins caught in 2005-2006. In addition, full samples have been taken whenever possible and from as many individuals as possible within the time available before the catch has been distributed, see Table 2. In 2007, there have been no catches of white-sided or bottlenose dolphins.

Grey seals Four grey seals, two immature males and two immature females, were fitted with satellite transmitters in June 2007, in a study on movements and distribution patterns of the species in Faroese waters. Three of the transmitters terminated after 200, 216 and 234 days, respectively, while one tag still transmitted 240 days after tagging (on January 30 2008). The seals have mostly stayed near their tagging site, but with some movements also to more distant islands. No significant offshore movements have been demonstrated; the most distant movements being 20 nautical miles out from land, for a week at the most. The seal movements have been accessible on the Museum website: www.ngs.fo .

2.3 Other studies Cetaceans T-NASS The Faroes was part of the Trans North Atlantic Sightings Surveys (T-NASS), conducted during summer 2007, under the auspices of the North Atlantic Marine Mammal Commission. The Faroese vessel, Thor Chaser, chartered by the museum, covered broadly the area inside the Faroese EEZ as well as an area south-west and south off the Faroes, south to 52.5°N. The vessel covered a distance of 1.520 nautical miles during 20 survey days. Fewer animals were observed during TNASS compared to NASS 2001.

Fin whale Checking the North Atlantic whaling statistics from the pelagic Norwegian catch and land stations in Ireland, the Hebrides, the Shetlands, the Faroes, Norway and Greenland is continuing and will hopefully be finished in 2008. A database including all data is under progress.

Pilot whale The development and testing of new equipment for killing pilot whales is still performed by the Veterinary Service. A report on the progress on this work is submitted to the NAMMCO Committee on Hunting Methods in January 2008. The Food, Veterinary and Environmental Agency performed tissue sampling for contaminants analyses from two pilot whale kills a year. The samples taken are primarily blubber and muscle and from a smaller selection of animals also kidney and liver. The samples are stored in the Environmental Specimen Bank at -20°C until analyses. Muscle samples are analysed for mercury, and blubber samples for persistent organic pollutants as PCB and “legacy” pesticides like DDT. Kidney and liver samples are analysed for mercury, cadmium and selenium, and some are even taken into a pilot study aiming to discover whether histopathological changes that could be ascribed for instance to the aforementioned heavy metals do occur. This pilot study is done in cooperation with the Dept. for Arctic Research at the National Environmental Research Institute (affiliated with the University of Aarhus) in Denmark.

A major part of the monitoring of long-range transported pollutants in pilot whale is done as part of the Arctic Monitoring and Assessment Programme (AMAP) under the 305

Faroe Islands – Progress Report Marine Mammals auspices of the Arctic Council, with resources from the DANCEA fund administered by the Danish Ministry of the Environment.

Monitoring of contaminants in pilot whale has been ongoing with irregular intensity since 1977, and the question of whether the pollutant loads are changing over time is important to address. Thus, a study of the statistical power of detecting such trends in the mercury concentration in pilot whales was performed and it turned out that the best chance of detecting changes would be provided by a sampling programme involving more juvenile individuals (Dam and Rigét, 2006). Therefore, the previous sampling programme that has been directed at taking a school representative sampling as would be pertinent when addressing the transfer of contaminants from pilot whale to the human through the food-chain, has been revised so as to include more juveniles. In addition to the monitoring of pollutants like PCB, dioxin and mercury, the pilot whales are analysed for other contaminants when the opportunity arises. In connection with a survey of dioxin in Faroese food, samples of pilot whale liver were analysed for dioxin, PCB including dioxin-like PCBs, pesticides as well as brominated flameretardants polybrominated diphenyl ether, PBDE. The rationale for including pilot whale liver in such a study was not its potential use as food, which it is not by all means, due to the high level of mercury, but rather an interest in acquiring knowledge of the ambient contaminant pressure on the pilot whale organism. Data on dioxin in pilot whale liver was published in a report intended for non-specialists (Dam and Hoydal, 2006). The brominated flameretardants hexabromocyclododecane, HBCD, and tetrabromobisphenole A, TBBA, were analysed in samples of pilot whale as well as in seabirds, mammals and fish from the Greenland marine environment (Frederiksen et al., 2007). Samples of pilot whale generally contained higher concentrations of HBCD than the other samples, and the overall highest HCB level was found in juvenile long-finned pilot whales blubber (119.8 ng/g lw).

White-sided and bottlenose dolphins A discoloured dolphin was observed in two drives of white-sided dolphins (12 August 2005, Fuglafjørður, 271 dolphins; 8 August 2006, Klaksvík, 327 dolphins; see Table 2) - see the animal at the bottom of the picture below. Both animals had about similar colour patterns. Full samples were taken and genetic examinations were undertaken by L.W. Andersen, DMU, Denmark, to examine whether the animals were an hybrid between e.g. white-sided dolphin and bottlenose dolphin or whether this was just a discolouration. The work is under progress.

3. CATCH DATA

Pinnipeds Some grey seals are shot every year, as a protection of salmon farms. But reporting is not mandatory and no catches are reported. The Ministry of Fisheries has promised to facilitate sampling of data. Cetaceans

Reporting is not mandatory. The Ministry of Fisheries will take initiative to have these informations in the mandatory logbook and facilitate sampling of data. By-catches of larger whales are usually reported by phone to the Museum. One immature female grey seal was caught by M/S Vesterland 22/11-2007 during long-line fishery on the Faroe shelf.

4.2 GREENLAND - PROGRESS REPORT ON MARINE MAMMALS IN 2006 - 2007

1. INTRODUCTION

This report summarizes the Greenland research on pinnipeds and cetaceans done in 2006 and 2007. Most of the research was conducted by The Greenland Institute of Natural Resources (GINR), but some projects also involved DFO (Department of Fisheries and Oceans, Canada), The Danish Environmental Research Institute (Department of Arctic Environment), Denmark, National Marine Mammal Laboratory, USA, Polar Science Center, Applied Physics Laboratory, Seattle, USA, Naturhistorisk Museum, København, Denmark, Naturhistorisk Museum, Oslo, Norway, Research Unit for Wildlife Population Assessment, University of St Andrews, Scotland, University of Århus and Woods Hole Oceanographic Institute.

2. RESEARCH

2.1 Species and stocks studied Pinnipeds • Walrus Odobenus rosmarus – Central West Greenland/ SE Baffin Island. • Harp seals Pagophilus groenlandicus – Southwest Greenland • Hooded seals Cystophora cristata – Southeast Greenland.

Cetaceans • Bowhead Whale Balaena mysticetus – Alaska, West Greenland • Narwhal – West Greenland - Monodon monoceros, West Greenland • Beluga – Delphinapterus leucas, West Greenland • Fin Whale Balaenoptera physalus – West Greenland • Humpback whale Megaptera novaeangliae - West Greenland, Brazil, South Pacific • Sei whale Balaenoptera borealis - West Greenland.

2.2 Field work Pinnipeds During March 2006, the Greenland Institute of Natural Resources (GINR) in cooperation with hunters from Sisimiut attached 5 satellite transmitters to walruses off Sisimiut in Central West Greenland in order to determine area use on the West Greenlandic foraging banks and spring migration. The transmitters that were remotely deployed by use of a cross-bow were attached to the skin of the back of the animals by a harpoon-head type anchor. This study was followed up in April 2007, with 8 satellite transmitters attached to walruses off Sisimiut.

During August 2007, staff from GINR, DFO, Danish National Environmental Research Institute (NERI) in cooperation with hunters from Sisimiut in Greenland and Pangnirtung and Qikiqtarjuaq in Canada and representatives of the Hunters and 311

Greenland – Progress Report Marine Mammals

Trappers Association (HTA) deployed a total of 8 satellite tags on walruses at terrestrial haul-outs at SE Baffin Island (SEB). Furthermore, skin biopsies were taken for genetic analyses. Data analysis is in progress.

During 21 March-19 April 2006 an aerial survey was conducted at between ca. 66° N and ca. 74° N in Central West Greenland to determine numbers of narwhal, beluga and walrus.

During two days in July, August and September 2006, respectively, GINR and Department of Fisheries and Oceans (DFO) in Canada flew aerial surveys over the terrestrial haul-outs for walruses on the coast of SE Baffin Island between Iqaluit and Qikiqtarjuaq. Representatives of HTA in Canada participated in planning the surveys and as observers. This study was repeated during three days in August, September and October 2007, respectively, Data analysis for 2007 is in progress.

The unusual event of a large group of harp seals whelping near the tip of Greenland was documented in spring 2007.

Seven adult hooded seals were caught off Southeast Greenland and equipped with satellite-linked time/dept/temperature recorders, during July 2007.

Cetaceans A total of 157 biopsies were collected from bowhead whales in Disko Bay between March and May 2007. The samples are being used for sex determination, genetic identification and stock identity.

A total of 75 samples of narwhals was collected from East and West Greenland and these are currently being analyzed for genetic diversity, age estimation by aspartic acid racemization of eye lenses and reproductive status.

Three bowhead whales were instrumented with satellite transmitters in Alaska in collaboration with Alaska Department of Fish and Game.

Nine bowhead whales were instrumented with satellite transmitters and three were instrumented with fluorometers in Disko Bay, April 2006 (GINR).

Thirteen gray whales were instrumented with satellite transmitters in Chukotka, Russia, September 2006, in collaboration with Chukot TINRO.

Fifteen humpback whales were instrumented with satellite transmitters off Brazil in October 2006, GINR in a collaborative study with Biodinamica, Brazil.

Two humpback whales were instrumented with satellite transmitters at the Cook Isles (Pacific Ocean) in collaboration with the National Marine Mammal Laboratory, in 2007.

NAMMCO Annual Report 2007 - 2008

Six narwhals were tagged with harpoon delivered satellite transmitters in Qaanaaq in August. In Melville Bay three narwhals were tagged with back-back transmitters in September and one was tagged with back-pack transmitter in Uummannaq in November.

Sonobouys were used for recordings of cetacean vocalizations in Baffin Bay in April and 57 hrs of recordings of primarily bowhead whale and narwhal vocalizations were obtained.

Four recording moorings were deployed cross the Davis Strait where they recorded from October 2006 - October 2007. Three moorings were successfully retrieved and downloaded (one was lost), each containing 1 yr of continuous recordings.

Multi-sensor, archival tags (DTAGs) with a pressure sensor and three-axis accelerometers and magnetometers were used to study in detail the kinematics of lunge feeding in humpback whales (Megaptera novaeangliae). Three tags were deployed during summer 2007 in Nuuk fjord.

55 ID-photos of humpback whales were collected in 2007 leading to the identification of 20 individuals in Nuuk fjord.

An aerial survey of cetaceans off West Greenland was conducted between 25 August and 29 September 2007. The survey platform was a Twin Otter operated by Air Greenland with four observer platforms and long-range fuel tanks. The survey was conducted as a line transect survey with cue counting data collection for the three target species; minke whales, fin whales and humpback whales. The survey was planned to systematically cover the banks off West Greenland from Uummannaq in the north to southernmost tip at Kap Farvel. East-west going parallel transects were chosen for most areas except for south Greenland were north-south going transects were deployed. Complex fjord systems were covered by a zig-zag transect design.

Aerial line transect surveys of narwhals were conducted in Inglefield Bredning and Melville Bay in August 2007.

A ship based survey for cetaceans was carried out between 27 June and 16 August 2007 in West Greenland. The survey was a line transect distance sampling survey with a single platform and three observers. The platform was a 93 ft coast guard ship, Tulugaq.

2.3 Laboratory work Pinnipeds Preliminary genetic analyses involving microsatellites compared samples of walruses from SE Baffin Island (SEB, 2006), Hudson Strait (HS) and Central West Greenland (CWG).

2.4 Research results Pinnipeds 313

Greenland – Progress Report Marine Mammals

The transmitters attached to walruses in Central West Greenland (CWG) in March 2006 signalled for a little more than a month during which time two animals got close to the coast of SE Baffin Island (SEB), and one moved from Store Hellefiskebanke north to the bank west of Disko Island. The others remained in the general survey area. In 2007 one animal of which the tags transmitted for about two months, moved from CWG to SEB. Furthermore during ground surveys at SEB in August 2007 an animal was observed at a terrestrial haul-out with a no longer functioning satellite tag that had been deployed in CWG. This was the third confirmed crossing from CWG to SEB since 2005, of walruses tagged in CWG.

The survey conducted in April 2006 resulted in an estimate corrected for potentially submerged animals during the surveys of 3,085 walrus (90% CI: 1239-7681 animals). The final survey results regarding narwhals and belugas are still not available.

Maximum number of walruses accounted for on the terrestrial haul-outs on the coast of SE Baffin Island during any of the months was 775+ walruses. If corrected for walruses potentially at sea during the surveys, an estimated 2600+ walruses were present at SE Baffin Island (SEB).

The genetic study of walruses found no genetic difference between SEB and CWG whereas walruses from HS differed slightly from the remainder. The analyses are continued involving a larger sample from SEB (2007) and CWG.

A large number of harp seal pups (white coats) were coming to Southwest Greenland with the drift ice from east Greenland during early April 2007. When the pups lost the white hair and turned into beaters they were included in the subsistence hunt. The skin purchase statistics show that more than 1,000 harp seal pups were born near the tip of Greenland far from the traditional whelping grounds.

The hooded seals with transmitters migrated from the moulting ground off Southeast Greenland to feeding grounds in the Davis Strait/Baffin Bay and from there down to the whelping ground off the Labrador/Newfoundland coast where they are at present. Hooded seals tracked in earlier years followed the same migration pattern.

Cetaceans The results of the tagging studies are still not available.

The aerial survey off West Greenland covered a total of 220,924 km2 and the accomplished effort was 9,434 km flown in sea state 5 of which 5,285 were flown in sea state 3. In terms of effort for cue counting estimation this corresponds to 190,163 seconds in sea state 5 of which 126,290 seconds were flown in sea state 3. A total of 25 sightings of fin whales, 27 sightings of minke whales, 21 sightings of humpback whales and 8 sightings of sei whales were obtained.

During the aerial line transect surveys of narwhals, a total of 328 sightings was obtained of which 32 were from Melville Bay. The data are currently being analyzed to develop fully corrected abundance estimates. 314

NAMMCO Annual Report 2007 - 2008

Several species of whales and seals were recorded from the moorings in Davis Strait. Preliminary analysis has shown that fin whales produce 20Hz pulses from September to February and in some months more than 100,000 calls are recorded. The power analysis programme is under development.

Analysis of 357 lunge feeding events provided little evidence that humpback whales accelerate forward before mouth opening to lunge at prey schools, but rather support the notion that they adjust their fluking to match the increased drag created from the opening of the mouth to maintain a steadier, slow speed throughout the lunge. As the drag increases with the cube of speed, adopting a slower speed will save oxygen and maximize dive times when foraging. It was concluded that humpback whales seem to gulp rather than lunge at prey laden water masses.

The photo-ID of humpback whales in Nuuk fjord, show that these whales are part of an open population with different foraging techniques. The open fjord allows the whales to migrate in and out throughout the season. Despite this, some individuals return to this specific fjord-system indicating year-to-year site fidelity.

The design of the ship based survey covered the west Greenland shelf and a total of 209 sightings were obtained on effort. Of these 57 were cetaceans.

3. ONGOING (CURRENT) RESEARCH

The harbour seal working group recommended a research program focusing on the remnant southern harbour seal population, beginning with the installation of stationary cameras at known haul out sites. Such cameras have now been made and will be put out in June when also an aerial survey will try to locate the breeding areas of these habour seals. The breeding localities have not been seen as these seals live in areas that only can be reached by boats in late summer and fall.

4. CATCH DATA

Walrus West Greenland are all walrus reported by hunters living on the vest coast south of Avanersuaq (76°N). For ringed seals the East Greenland population is here defined as ringed seals that are caught in East Greenland or in one of the three southernmost municipalities on the West coast, whereas the rest belongs to the Baffin Bay population. Hooded seals are only considered East Atlantic if they are caught in Ittoqqortoormiit. All harp seals caught in Ittoqqortoormiit are believed to come from the Greenland Sea population, whereas catches from Ammassalik are split fifty-fifty between the Greenland Sea and the West Atlantic populations.

Reported catches on pinnipeds and small cetaceans are only available from 2006. The figures are preliminary and small adjustments are likely to be made.

5. BY-CATCH DATA

• One humpback whale (female) entangled in pond net for cod, euthanized (Greenland). • One humpback whale entangled in pond net for cod, died (Greenland). • One humpback whale entangled in pond net for cod, came free by its self (Greenland). • One Bowhead whale entangled in fishing gear for crabs, came free by its self (Greenland). • One Bowhead whale entangled, gear not specified, died (Greenland).

6. ADVICE GIVEN AND MANAGEMENT MEASURES TAKEN

NAMMCO working group on harbour seals advised a total cessation of harbour seal hunting in all Greenland in order to provide an opportunity for recolonization of abandoned breeding areas in west Greenland by a remnant population in the extreme south.

No management measures have been taken so far.

NAMMCO has earlier advised a reduction in the catch number of walrus.

New regulations of the walrus hunt from 2006 give better protection of females and calves accompanied by females. Quotas have also been introduced. These quotas will gradually be reduced in order to meet the advised catch number in 2009.

4.3 ICELAND PROGRESS REPORT ON MARINE MAMMAL RESEARCH IN 2006-2007 Compiled by Gísli A. Víkingsson, and Droplaug Ólafsdóttir. Marine Research Institute, Reykjavík Iceland

1. INTRODUCTION

The following reports on studies on marine mammals in Icelandic and adjacent waters in 2006-2007. As in previous years most of the studies were conducted by the Marine Research Institute (MRI) and its various research partners. Queries for information on research were sent to all offices or individuals known to have been involved in marine mammal research or data collection during the period, including the Research Committee for Biological Seafood Quality (RCBSQ) the Institute of Natural History (INH), University of Iceland, Icelandic radiation protection institute as well as data collection from private commercial platforms such as whaling and whale watching companies.

In 2006, research effort on marine mammals at the MRI was largely devoted to the wide ranging research programme on common minke whales initiated in 2003. In addition to completing the sampling phase of the common minke whale research programme in 2007, research resources were primarily concerned with a large scale cetacean survey in the North Atlantic (TNASS). Progress of the programme is reported under respective headings according to the guidelines for national progress reports submitted to NAMMCO.

2.2. Field Work Pinnipeds Harbour seals were counted from an aircraft, along the entire Icelandic coast in August 2006. In 2006 about 20 samples of tissue from grey seals were collected for genetical studies on grey seal populations in the North-Atlantic and sent to Anne Kirstine Frie University of Tromsø, Norway. In 2007, Samples from two harp seals, 15 harbour seals and 23 grey seals, were collected for food studies, nematode and acanthocephalan infestation in the digestive tract, genetics, biopsy of fat, meat, liver and kidneys, and diseases in the intestines. The animals were also measured and weighed. In 2007 samples of tissue from Icelandic harbour seals were collected for genetical studies on harbour seal populations in the North-Atlantic and sent to the University of Copenhagen, Denmark for laboratory analysis.

Cetaceans Strandings Information on stranded cetaceans in Iceland is compiled by the Marine Research Institute in cooperation with the Institute of Natural History and other relevant institutions (Table 1). In 2005 a formal arrangement regarding authority and responsibilities of different governmental agencies concerning cetacean strandings was adopted and put into force in 2006. According to this arrangement the Marine Research Institute is the central authority concerning science and research while other aspects of strandings s.a. euthanasia/rescue, disposal of carcasses and preservation of museum specimens fall under the responsibilities of the Chief Veterinary Office, the Environment Agency of Iceland and Institute of Natural History respectively.

Depending on the condition of the stranded animals, samples are taken for diet studies (stomach), life history studies (teeth, ear plugs, gonads), genetic studies (skin, muscle), energetic studies (muscle, blubber) and for morbillivirus antigen screening (blood). Various tissue samples for pollution studies have been routinely collected during dissections of stranded or by-caught cetaceans in recent years. These are stored frozen at the MRI (Table 2).

The common minke whale research programme During 15 June – 22 August 2006, 27 April – 20 June 2007 and 24 August – 2 September 2007, 60, 33 and 4 common minke whales respectively were caught under special permit in accordance with the original research proposal (MRI 2003).

The whales were caught from four minke whale catching boats hired by the Marine Research Institute: Njörður, KÓ-7 (18.04m, 30 tons), Halldór Sigurðsson, ÍS-14 (17.6m, 41 tons), Trausti, ÍS-111 (25m, 93 tons) and the former research vessel Dröfn –RE-35 (25.9m, 155 tons). The crew was mostly composed of experienced minke whalers, and 1-3 scientists were onboard each of the vessels. Cruise leaders from the Marine Research Institute were in charge of the operation onboard each vessel.

Searching effort was distributed all around Iceland in proportion to known densities of minke whales in the nine areas as laid out in the original sampling scheme (MRI 2003). Minor sampling constraints were imposed by avoidance of whale watching areas and unfavourable weather conditions in offshore areas.

Dissection and sampling took place on board the vessels. Detailed weighing of all tissues and organs was conducted on eight animals. Sampling effort was similar to the previous sampling in the programme (see NAMMCO 2007, p. 513-517)

Data from commercial catch Seven fin whales were caught west of Iceland as a commercial catch in October 2006. Blubber thickness and morphometric measurements were taken as well as samples for analyses on pollutants (see item 2.4), reproductive biology, age (ear plugs, eyes), genetics (skin, muscle), diet (stomach content, skin, blubber) and hormones (urea).

Genetic samples were taken from one and six common minke whale caught as commercial catch in 2006 and 2007 respectively.

Sightings data Systematic sightings surveys T-NASS

324

NAMMCO Annual Report 2007 - 2008

In the summer of 2007 the MRI participated in the Trans North Atlantic Sightings survey, (T-NASS) the largest synoptic cetacean survey ever attempted. This survey was the 5th in the series of North Atlantic Sightings Surveys (NASS) previously conducted in 1987, 1989, 1995 and 2001, in all of which Iceland has participated. In addition to the full partners of T-NASS (Iceland, Faroe Islands, Greenland, Norway, Canada and the Russian Federation) the survey was coordinated with cetacean surveys off western Europe (CODA) and the east coast of USA (SNESSA). On behalf of T- NASS, cetacean observers were also placed onboard other research vessels operating simultaneously in adjacent areas in the North Atlantic. Further details regarding overview and scope of the survey (T-NASS and associated surveys) can be found at the website of NAMMCO (www.nammco.no).

Three vessels and one aircraft participated in T-NASS on behalf of Iceland, covering most of the central North Atlantic area in close cooperation with one Faroese vessel. Cruise reports and preliminary abundance estimates for the main target species were submitted to the NAMMCO working group on abundance estimates (SC/15/TNASS/29, SC/15/AE/05, SC/15/TNASS/40, SC/15/TNASS/30, SC/15/TNASS/31).

Incidental sightings Monitoring of sightings during whale watching operations was conducted in Faxaflói and Húsavík. Sighting and effort data is stored at each whale watching company and partly at MRI.

MRI and a whale watching company operating in SW Iceland co-operated in reporting and compiling sightings data during whale watching excursions. This is a pilot project, initiated in 1999, for investigating the feasibility of using whale watching boats for systematic collection of data on distribution and relative abundance of cetaceans in nearshore Icelandic waters.

Telemetry data In 2006 the Marine Research Institute participated in a multinational research project for the study of acoustics and movements of white-beaked dolphins in Icelandic waters. Two animals were captured and released after acoustic experimentation. One of the animals was instrumented with a satellite tag. Transmissions were received from the time of tagging in August 2006 until February 2007. During this period the animal moved extensively but never left the western part of the Icelandic continental shelf area.

In 2007 the same international group of scientist attempted to use the same methods on a common minke whale in Faxaflói bay using a purse seine instead of the hoop net as used for the dolphins in 2006. These attempts were unsuccessful as no minke whales could be captured.

Unsuccessful attempts were made to instrument common minke whales with satellite and TDR tags in summer and fall of 2006. Three humpback whales were instrumented

325

Iceland – Progress Report Marine Mammals with satellite tags in the autumn of 2007. Data were received from one of the animals for few days.

Biopsy sampling No skin biopsies were obtained in 2006 and 2007.

Natural marking Catalogues of individuals based on natural marking data are held at the MRI for blue, humpback and killer whales. Photographs are obtained in special cruises as well as from opportunistic platforms. No cruises were conducted in 2006-7 specifically to collect photo-ID data. Collection of photos of white-beaked dolphins and common minke whales were collected from whale watching platforms in Faxaflói Bay (Bertulli and Ratayczak 2007) and some photo ID material was also collected in other inshore whale watching locations.

2.3 Laboratory work Pinnipeds Age determination In 2006, age was determined from cross sections of canine tooth delivered to the RCBSQ, from a total of 112 grey seals and a single harbour seal.

Cetaceans Common minke whale research programme The originally scheduled sample size of 200 common minke whales was achieved in 2007. The sampling phase of the programme is thereby finished. The status of different sub-projects of the programme to date is discussed under the representative sections below.

Feeding and energetics Diet composition Initial prey species identification from all forestomach samples was completed in 2007. Determination of age and length of fish prey from otoliths is underway. Two samples of 8 common prey species each have been prepared for measurements of stable isotopes, fatty acids. Further processing is underway.

Energetics Laboratory analysis on the energy density of muscle, blubber and visceral fat from all animals from 2003, 2004 and 2005 and liver and kidneys from 25 animals from 2003 and 2004 is finished. Evaluation of this data is ongoing.

Two samples of 8 common prey species each were prepared for measurements of energy density. Further processing is underway. 25 samples each of muscle, skin and blood, 75 samples in total, have been analysed for stable isotopes. Evaluation of results awaits results from prey species for comparison.

Pathology

326

NAMMCO Annual Report 2007 - 2008

Work continued on the various aspects of pathology of common minke whales such as hematology and serology, microbiology, virology and histology. The details of these analyses were outlined in previous progress reports.

Parasites External parasites from all samples have been analysed.

Biological parameters Gonads from all animals caught in 2006 and 2007 (50 females and 45 males) have been analysed for sexual maturity for both sexes and reproductive history for females. Analyses of growth layers in earplugs is underway. Analyses of amino acid racemisation (AAR) in 100 eye lenses from 86 animals taken in 2003, 2004 and 2005 are completed. AAR analyses of lenses collected in 2006 and 2007 are ongoing.

For verification of the amino acid racemisation method, eye lenses from 50 Antarctic minke whales (Balaenoptera bonaerensis) from the JARPA project are being analysed. The results will be compared to age readings already obtained from ear plug readings for those same animals

Environmental contaminants Of the 95 samples collected in 2003, 2004 and 2005, 25 animals have been selected for detailed studies on organic and inorganic contaminants. All tissues samples for trace elements have been processed and analysed except bones that were sampled in 2007. Evaluation of data is ongoing. Five animals from 2003 have been analysed for dibenzo-p-dioxins, dibenzofurans, dioxin-like PCBs and marker PCBs in blubber while the analysis of the remaining samples for organic contaminants of the original programme is ongoing. Some of these will be done in laboratories outside Iceland.

Interpretation and diagnostic work on trace elements with reference to biological parameters (age, size, sex, etc), pathology, trophic status, body condition and geographical variation is underway.

Genetics Laboratory analysis of all samples collected in 2003–2007 for the stock structure component of the minke whale research programme is completed. Today, all samples collected in Icelandic waters from 1981 to 2007 have been genotyped for 16 microsatellite loci and the mtDNA (n= 342 for the microsatellite loci; n= 347 for the mtDNA). In addition, samples collected at feeding grounds in Greenland (n=37), Barents Sea (n=50), Norway coastal region (n=37), Spitsbergen (n=63) and North Sea waters (n=7) were genotyped for geographical comparisons. The genetic analyses have been performed and a manuscript is in preparation.

In 2007, collaboration was initiated between the MRI and scientist at WHOI and Harvard Medical School in USA on the structure of the auditory system in common minke whales. Samples taken for this purpose will be sent to the USA for analysis.

Strandings 327

Iceland – Progress Report Marine Mammals

Laboratory work on blood sampled from stranded and by-caught cetaceans screened for morbillivirus antibodies at the Institute for Pathology, University of Iceland.

Analyses of abundance and trends In 2006 large effort was placed on analysis of data from the North Atlantic Sightings survey (NASS) series 1987-2001. The results of these analyses will be published in a Special Volume of NAMMCO Scientific Publications, including new information on distribution, abundance and trends of blue, fin, minke, humpback, sperm, and Northern bottlenose whales.

Data from the T-NASS survey conducted in 2007 have been validated and abundance estimation work was initiated in 2007. Preliminary abundance estimates for the main target species (fin and common minke whales) were submitted to the NAMMCO Working Groups on T-NASS and Abundance Estimates (SC/15/TNASS/29, SC/15/TNASS/30, SC/15/TNASS/31, SC/15/AE/4,SC/15/AE/5).

Genetics Fin whale Samples of fin whales from Iceland 1981-2006 (n=1,069), Spain 1985 (n=46), Norway (n=57), West Greenland (n=16) and East Canada (n=38) were statistically analysed for 9 microsatellite loci in order to study the spatio-temporal structure of Northeast Atlantic fin whales (Daníelsdóttir et al. 2005; 2006c).

A sub-sample of the total fin whale samples (Iceland 1985, 1987 and 1989 (n=128); Spain 1985 (n=43); Norway (n=39); West Greenland (n=16) and East Canada (n=13) was analysed further. They were screened and statistically analysed for mtDNA sequences and 6 microsatellite loci (same as in Bérubé et al. 1998; Bérubé et al. 2006) and also 16 microsatellite loci (Bérubé et al. 2002; Daníelsdóttir et al. 2006c and Skaug et al. 2006). Reanalysis of North Atlantic fin whale allozyme data is presented in Daníelsdóttir et al. (2006a). Finally, several individuals were selected to run more microsatellite loci and the mtDNA. A total of 365 individuals from Iceland as well as 39 from Norway, 43 from Spain, 15 from West Greenland and 13 from Canada were successfully genotyped and analysed for 15 microsatellite loci, a sex-specific marker and the mtDNA. These results were presented at a technical workshop in December 2007 as a part of the RMP implementation process conducted within the IWC Scientific Committee (Pampoulie et. al 2007).

Common minke whale – see common minke whale research programme above.

Natural marking Analysis of all available photo-ID material on humpback whales in Icelandic waters (archived at the MRI) is at a final stage.

Analysis of 89 blue whales photo-identified off Iceland during 1996-2003 yielded no matches with a large catalogue (400 individuals) from the Gulf of St Lawrence, the Nova Scotia shelf and the Gulf of Maine. In 2005, a blue whale was photographed off

328

NAMMCO Annual Report 2007 - 2008

Mauritania, West Africa and was identified to be the same as one previously photographed off Iceland on two occasions, in 1997 and 1999. This is the first match between Iceland and any other region for this species and represents the longest range re-identification of blue whales in the North Atlantic or 5,200 km (Sears et al. 2005).

Photos of cetaceans taken during whale watching excursions in S.W. Iceland were archived at MRI. Studies conducted from commercial whale watching vessels included a photo-ID study on common minke whales and white-beaked dolphins in Faxaflói Bay in 2007.

2.4 Other studies A study conducted by Hvalur h.f. on levels of trace elements and organic micropollutants in fin whales caught of Iceland in 2006 has been carried out. Analysis of the results is underway. Age determinations of the same animals have been estimated from growth layers in ear plugs.

A collaborative study between MRI scientists and colleagues from Norway and Scotland on stock structure and movements on killer whales in the Northeastern Atlantic was initiated in 2006 (Foote et al. 2007).

Various analyses were conducted in relation to the IWC pre-Implementation Assessment of North Atlantic fin whales (Daníelsdóttir et al. 2006b, Víkingsson et al. 2006), including genetic (Daníelsdóttir et al. 2006a; 2006c, Berubé et al. 2006, Skaug et al. 2006) and non-genetic indications of stock structure (Víkingsson and Gunnlaugsson 2005) and abundance. Data on life history parameters for fin whales caught in 1967 to 1989 has been revalidated and reanalysed in particular with respect to spatial and temporal segregation (Gunnlaugsson and Víkingsson 2006, Víkingsson 2006).

Results from a collaborative study concerning health of harbour porpoises in the Northeast Atlantic were published in 2006 (Das et al. 2006, Siebert et al. 2006).

2.5 Research results Pinnipeds Based on the survey in August 2006 the harbour seal population was estimated as 12,000 (95%CI 9,000-16,000) animals.

Cetaceans Preliminary results from analyses of stomach contents of minke whales have been presented at the annual meeting of NAMMCO in 2006 and in other fora in Iceland. Icelandic data relevant to management and in particular the RMP pre-implementation and implementation of North Atlantic fin whales were presented to the annual Joint NAMMCO/IWC scientific workshop on catch history, stock structure and abundance of North Atlantic fin whales in March 2006. Results of studies on the acoustics and movements of white-beaked dolphins were presented at conferences of the European Cetacean Society and the Society for Marine Mammalogy. Various analyses on distribution and abundance of cetaceans in Icelandic and adjacent waters based on the 329

Iceland – Progress Report Marine Mammals

North Atlantic sightings surveys 1987-2001 will be published in a highly ranked journal (NAMMCO Sci. Publ.) in 2008.

3. ONGOING (CURRENT) RESEARCH

In August 2003, the government of Iceland decided to start implementation of a wide ranging research programme concerning common minke whales. Progress has been reported to the Scientific Committees of NAMMCO and the IWC SC (Víkingsson et al. 2004, 2005, 2006, 2007; NAMMCO 2005, 2006, 2007). The collection of 200 common minke whales was completed in 2007 after 5 seasons (4 years) of sampling instead of two years according to the originally submitted research proposal. The objectives, methodology, total sample size and spatial and seasonal distribution of the sample remain unchanged (for details see MRI 2003) and the modifications involve only a longer sampling period. Analyses of samples for the various sub-projects are ongoing (see item 2.3 Common minke whale research programme).

Analyses of data from the 2007 international sightings survey T-NASS of abundance estimates is ongoing and preliminary estimates for the primary target species presented at NAMMCO working group meetings in April 2008 (SC/15/TNASS/29, SC/15/TNASS/30, SC/15/TNASS/31, SC/15/AE/4,SC/15/AE/5).

4. BY-CATCH DATA

Reporting of marine mammal by-catch in the Icelandic fishery is mandatory. All fishing vessels are obliged to report catch and by-catch in log books. No observation scheme is carried out in order to evaluate the reliability of the system. The reporting is entirely based on the cooperation of the fishermen and is therefore voluntary in practice, most likely resulting in inadequate monitoring of marine mammal by-catch in the Icelandic fishery.

Data on marine mammal by-catch in the gill net fishery has been obtained in observer covered surveys conducted by MRI in April the years 2003-2007.

5. ADVICE GIVEN AND MANAGEMENT MEASURES TAKEN

Direct catches Pinnipeds In 2006 direct catch of seals consisted of 192 harbour seals (Phoca vitulina) (100 pups, 1 1+ animals and by-catch of 91) and 286 grey seals (Halichoerus grypus) (99 pups, 112 1+ animals and by-catch of 75).

Preliminary data on direct catch of seals in 2007 consists of 72 harbour seals (Phoca vitulina) (72 pups, 0 1+ animals and by-catch of unknown number) and 267 grey seals (Halichoerus grypus) (84 pups, 183 1+ animals and by-catch of unknown number).

As in recent years Icelandic authorities issued a permit to Norwegian sealers to catch harp seals inside the Icelandic EEZ but to date the MRI has not received catch data for 2006-2007 (see also below). These catches are included in Norwegian catch statistics.

Cetaceans A total of 60 and 37 common minke whales were taken as a part of the Icelandic research programme in 2006 and 2007 respectively. A total of one and six common minke whales were taken as a commercial catch in 2006 and 2007 respectively. These catches were taken from Icelandic continental shelf waters (Central North Atlantic stock, CIC sub-area). Seven fin whales were taken as commercial catch in October 2006. These catches were taken in the area west of Iceland (East Greenland-Iceland stock, EGI sub-area).

Pinnipeds Advice given for harbour seals in 2006 and 2007 was in accordance with advice given in 2005. Based on the most recent survey of harbour seals from August 2003 and 2006 respectively the MRI concluded that due to uncertainties in the number of net- entangled animals it is not possible to predict whether the observed decline in abundance in the past will continue, although recent hunt rates are much reduced. The MRI therefore stressed the importance of better by-catch recording and that the stock was monitored, including aerial surveys at 2 or 3-year intervals in the coming years. The MRI called for management objectives for the stock of harbour seals.

Advice given for grey seals in 2006 and 2007 was identical to advice given in 2005. The management objectives set for the grey seal stock in 2005 calls for action if the 331

Iceland – Progress Report Marine Mammals stock is further reduced below the estimated level in 2004 of 4,100 animals. Based on the survey in 2005 this was not considered likely to be the case. The MRI stressed the importance of regular monitoring.

Based on concerns expressed by the Scientific Committee of NAMMCO regarding low numbers of hooded seals from a survey in 2005 (NAMMCO 2007), Icelandic authorities declined issuing permits to Norwegian sealers to catch this species within the Icelandic EEZ in 2006 and 2007.

Cetaceans In October 2006, the Icelandic minister of Fisheries issued a permit to catch up to 9 fin whales and 30 common minke whales for commercial purposes. These catches were the first commercial catches since the moratorium imposed by the IWC took effect at the end of the 1985 season. In October 2006, 7 fin whales and a single common minke whale were caught from this quota. In 2007, 6 common minke whales were taken for commercial purposes.

The MRI recommended a precautionary TAC of 150 fin whales if all catches are taken on the traditional grounds west of Iceland. If catches are distributed over a wider area the recommended TAC was 200 fin whales. Similarly a total limit of 400 minke whales within the Icelandic EEZ was recommended by the MRI.

2.2 Field work Pinnipeds 2006 Biological material, to establish age distributions in catches as well as health, reproductive and nutritive status of the harp seals were collected from commercial catches in the southeastern Barents Sea in April/May. (IMR)

In May/June 2006, a Norwegian survey was conducted, aimed to study the feeding habits of harp seals occurring in the open waters of the Barents Sea. No seals were seen in the open, ice-free areas. In the northwestern parts of the Barents Sea, however, very large numbers of seals were observed along the ice edge and 20-30 nautical miles south of this. (IMR)

Physiological studies of hooded seals from the Greenland Sea stock were conducted during a research cruise with R/V “Jan Mayen” in the Greenland Sea between 15 and 30 March 2006. A total of 4 adult female and 8 newborn hooded seals were culled and used in studies concerning a) neuronal tolerance to hypoxia (oxygen shortage), b) adaptations to fasting in pups, and c) heart physiology, as further outlined: a) Studies of hypoxia tolerance of nervous tissue from hooded seals are conducted in collaboration with Dr. T. Burmester, Zoologisches Institut und Museum, Universität Hamburg, Germany. Samples were collected from 4 adult and 4 newborn seals, from the cerebral cortex (occipital region), cerebellum, medulla oblongata, and retina, for later immune-histochemical studies of regional differences in the distribution of the respiratory protein neuroglobin, as well as of various metabolic enzymes. The work focuses on understanding how seal neurons cope with lack of oxygen and can maintain energy supply during long duration dives that may render these animals severely hypoxic. b) Four pups, 2 recently born, and 2 weaned, were killed and dissected to determine the weight of different tissues, including blubber, muscle and various internal organs. The purpose of these investigations is to estimate how much energy is deposited during the short and intensive lactation period of the hooded seal, and to calculate the possible maximum duration of the postweaning fast. c) Samples of cardiac (heart) muscle were collected from altogether 11 hooded seals (4 adult and 7 pups), for later immune-histochemical studies of the occurrence and distribution of gap junction proteins (connexins) in cardiomyocytes. Gap junctions are responsible for the electrical cell-to-cell communication between cardiomyocytes that secures the coordinated and controlled contraction of the heart. The proteins, connexins, that make up the gap junctions may occur in several isoforms. Previous studies in non- diving mammals have shown that the connexin isoform composition changes both with age and in response to hypoxia. The purpose of the present study was to investigate whether the connexin occurrence and distribution in the heart of a diving and hypoxia- tolerant species like the hooded seal might reflect particular adaptations, possibly to secure proper heart function under severely hypoxic conditions. Also, age effects on connexin composition were studied.

In addition to these studies, a pilot tagging of 1 weaning hooded seal with a satellite- linked dive recorder was made during the cruise, in order to study the movements and dive behaviour of this species during the first year of life. Finally, 4 weanling hooded 338

NAMMCO Annual Report 2007 - 2008 seals were live-captured and brought to the Department of Arctic Biology (AAB), for later detailed studies of various aspects of neuronal tolerance to hypoxia during diving, and of adaptations to fasting. In addition to the samples collected for own projects, various samples were also collected for other scientific projects, as organised by other research groups (e.g., the project “Hoodhealth” – Norwegian School of Veterinary Science - Section of Arctic Veterinary Medicine (NVH-SAV)). The described research was combined with extensive teaching of the 19 students that participated in the cruise, which represents a mandatory part of the recently established course “Arctic Biology” (BIO-2310) at the University of Tromsø. The combination of research and teaching proved to be very fruitful and may hopefully contribute to improve recruitment of students to the field of arctic biology in general, and to marine mammal biology in particular (UiT-AAB).

In the period March-June, 2006, altogether 8 adult harbour seals were culled outside the coast of Troms, northern Norway, in connection with the project “The pineal gland of the fetal seal”. The purpose of this project is to elucidate the function and role of the unusually large and active pineal gland of the pinniped fetus. Thus, culling of pregnant adult females was required, for collection of tissue samples (pineal gland, blood) from both mother and fetus. Altogether, 5 adult pregnant females were culled, recovered and sampled, while 3 adults of unknown sex were killed but lost during attempts of recovery (UiT-AAB).

Abundance estimation using boat based visual surveys was performed for harbour seals in South Norway in August (i.e., the moulting period, methodology based on total counts). Additionally, to be able to adjust the estimates for animals not hauled out during the surveys, the haulout behaviour of the species was investigated on a special location in Rogaland, Southwest Norway, in August. (IMR)

Abundance estimation (using pup counts) and sampling of biological material for studies of breeding biology (including tagging of pups), in particular the temporal distribution of births, and stock identity (biopsy samples for genetic analyses) was performed for grey seals in ship borne surveys in North Norway in November - December. (IMR)

Material to assess demographic parameters (teeth, measurements) and population structures (tissues for genetic analyses) were collected from the Norwegian grey and harbour seal hunt. (IMR)

In 2006 adult bearded seals in Svalbard were equipped with small cameras to study behaviour during foraging and prey handling in addition to study the effect of foraging on the benthic environment (bioturbation). Bearded seal pups were equipped with satellite transmitters to study diving development. (NP)

The walruses in Svalbard were surveyed during the first part of August. All known haul- out sites were surveyed and sites that were in use were documented using digital photography. An extensive behavioural dataset from walruses equipped with satellite transmitters was used to create a model that accounted for walruses that were in the water 339

Norway – Progress Report Marine Mammals at the time of the survey to produce an estimate for total numbers of walruses present in the archipelago at this time of the year. (NP)

2007 It is recommended that comprehensive aerial surveys needed to provide estimates of current pup production should be conducted periodically (c. every 5 year), and that efforts should be made to ensure comparability of survey results. Recent abundance estimate for hooded seals in the Greenland Sea from 1997 and 2005 have indicated stagnation or maybe even reduction in pup production. For this reason, new surveys were carried out in March-April 2007 using an icegoing vessel (‘Nordsyssel’), one helicopter and two fixed- wing aircrafts. Both hooded and harp seal pup production was surveyed. (IMR) Biological material, to establish health, reproductive and nutritive status of the hooded seals was collected during research surveys in the Greenland Sea in April/May. (IMR) Tissue samples were collected from harp seal pups in the Greenland Sea (50 individuals, taken on Norwegian sealer) – also several samples were obtained from a new harp seal breeding patch in the Denmark Strait (from Greenland hunters). All samples will be subject to genetic (DNA) analyses. (IMR)

Studies of hooded seals from the Greenland Sea stock were conducted during a research cruise with R/V “Jan Mayen” in the Greenland Sea between 17 March and 01 April 2007. A total of 6 adult female and 6 newborn hooded seals were culled and used in studies concerning a) neuronal tolerance to hypoxia (oxygen shortage) and b) adaptations to fasting in pups, as further outlined: a) Studies of hypoxia tolerance of nervous tissue from hooded seals are conducted in collaboration with Dr. T. Burmester, Zoologisches Institut und Museum, Universität Hamburg, Germany, and Dr. E. Messelt, Institutt for Oral Biologi, Universitetet i Oslo. Samples were collected from 4 adult seals from the cerebral cortex (occipital region) and the cerebellum, for later immune-histochemical and electron microscopical studies of the distribution of mitochondria in neuronal and glial cells. This work is part of a program addressing the mechanisms underlying the extreme neuronal hypoxia tolerance typical of many diving species. b) Four pups, 2 recently born, and 2 weaned, were killed and dissected to determine the weight of different tissues, including blubber, muscle and various internal organs. The purpose of these investigations is to estimate how much energy is deposited during the short and intensive lactation period of the hooded seal, and to calculate the possible maximum duration of the post-weaning fast. In addition to samples collected for own projects, various samples were also collected for other scientific projects.(UiT-AAB)

Additionally, 4 weanling hooded seals were tagged with satellite-linked dive recorders in order to study movements and dive behaviour of this species during the first year of life. Another 4 weanling hooded seals were live-captured and brought to the Department of Arctic Biology (AAB), for later studies concerning neuronal tolerance to hypoxia during diving and aspects of their renal physiology. (UiT-AAB)

Hooded seals were equipped with satellite-relayed data-loggers that also have incorporated a conductivity-temperature sensor into them so they function as a CTD in 340

NAMMCO Annual Report 2007 - 2008 addition to give “normal” information on positions and diving. This fieldwork was carried out in the Greenland Sea during July and August and is part of a larger IPY- project called MEOP (Marine Mammals Exploring the Oceans Pole to Pole). (NP) The described research was combined with teaching of 11 students that participated in the cruise, which represents a mandatory part of the course “Arctic Biology” (BIO-2310) at the University of Tromsø (UiT-AAB)Tissue sampling to assess the stock identity of harbour seals using DNA analyses were initiated in Vesterålen, North Norway, in June when biopsy samples from pups were taken. (IMR)

Feeding habits and habitat use of harbour seals in Vesterålen, Norway, were investigated by feaces sampling and trawling from spring to autumn (February-October), and with deployment of GSM-based tags on 5 seals in September. (IMR)

Abundance estimation (using pup counts) and sampling of biological material for studies of stock identity (biopsy samples for genetic analyses) was performed for grey seals in ship borne surveys in North Norway in September - October. Some areas were also covered with simultaneous aerial surveys. (IMR)

Material to assess demographic parameters (teeth, measurements) and population structures (tissues for genetic analyses) were collected from the Norwegian grey and harbour seal hunt. (IMR)

Bearded seal pups were captured to study growth and some were instrumented with accelerometers to study diving. This fieldwork was done in Kongsfjorden, Svalbard, during May.(NP)

Ringed seals were collected for ecotoxicologial studies in Van Keulenfjorden and Tempelfjorden in Svalbard during April. (NP)

Cetaceans 2006 During the period 3 July to 6 August 2006 a sighting survey was conducted with two vessels covering the Small Management Area EW, which includes the waters off the Finnmark coast, Lofoten/Vesterålen and the eastern parts of the Norwegian Sea. This was the fifth year of the recent six-year program 2002-2007 to cover the northeast Atlantic to provide a new abundance estimate of minke whales every sixth year as part of the management scheme established for this species. A total of 2,300 nautical miles was surveyed on primary effort and 121 sightings of minke whales were made during this effort. Sightings of other cetacean species include sperm whales (107 primary sightings), Lagenorhynchus dolphins (91 primary sightings), killer whales (47 primary sightings), harbour porpoise (43 primary sightings), fin whales (25 primary sightings) and humpback whales (5 primary sightings). VHF radio tags were put on two minke whales and these were followed for 18 hours over 50 nmi and for 39 hours over 80 nmi, respectively. Biopsy samples were collected from 11 minke whales, one fin whale, one humpback whale and three sperm whales. Identification photos were collected from humpback, minke, fin and sperm whales.

In August-September field work was conducted off Spitsbergen and in the Barents Sea to instrument whales for collecting dive time data and studying their migrational behaviour. At this time of the year, these areas usually have reasonable high densities of minke whales but this turned out to be different in 2006 as only very few minke whales were observed and none were possible to close on for attachment of tags. Off Spitsbergen some blue whales were observed, and one of these was instrumented with a satellite tag. Also two fin whales were approached and tagged, but none of the instruments provided signals. Biopsies were collected from five fin whales, five humpbacks and three blue whales. (IMR)

In April-June 2006 mapping of whale distributions was conducted during an ecosystem survey in the Norwegian Sea by having dedicated whale observers onboard who collected information following line transect protocols. A similar effort was conducted during the ecosystem surveys in the Barents Sea in August to September 2006. (IMR)

During the traditional whaling season (April-October), body condition data and tissue materials for studies of DNA identity were collected from all minke whales taken by vessels participating in the Norwegian small type whaling. (IMR)

Collection of humpback whale photo IDs continued in 2006, and a total of about 30 individuals were sampled during several effort occasions this year. (IMR)

A search for bowhead whales in the Greenland Sea along the ice edge between Svalbard and Greenland was conducted during the second half of April. Bowhead whales were observed at several occasions and biopsies for genetic analyses were collected from several individuals. There were 8 observation events that included 17-20 bowhead whales. All whales were detected visually from the vessel’s bridge and all observations were made in a relatively small area of the Fram Strait over the continental slope at depths between 1,030 and 2,785 meters. Age and sex of the animals were not determined, but those whales those whales that were approached with small boats for biopsy darting were at least 15 m long. (NP, NHM)

2007 IMR vessels and coastguard vessels have collected incidental observations of marine mammals. Recorded data include date, position, species and numbers. During 2007 a total of 965 observation incidents have been reported. The most frequently observed species were minke whales (224), Lagenorhynchus dolphins ( 181), fin whales (136), humpback whales (107), harbour porpoises (82), killer whales (57) and pilot whales (30).

During the period 2 July to 5 August 2007 a sighting survey was conducted with two vessels covering the Small Management Area EB, which includes the Barents Sea proper east of 28ºE eastwards to and from the Norwegian and Russian coastal areas northwards to the ice-edge. This was the last year of the recent six-year program 2002-2007 to cover the northeast Atlantic to provide a new abundance estimate of minke whales every sixth year as part of the management scheme established for this species. A total of 2,230 nautical miles was surveyed on primary effort and 159 sightings of minke 342

NAMMCO Annual Report 2007 - 2008 whales were made during this effort. Sightings of other cetacean species include fin whales (25 primary sightings), humpback whales (19 primary sightings), Lagenorhynchus dolphins (204 primary sightings), harbour porpoise (76 primary sightings) and killer whales (1 primary sighting). One observation of particular interest was made 13 July 2007 of a Greenland right whale in the Barents Sea at position 78º12’N, 39º01’E. Biopsy samples and associated identification photos from about 50 humpback whales were collected.

In July whale observers were placed onboard two chartered vessels doing fish surveys in the Norwegian Sea, as part of a contribution towards the TNASS survey effort to map whale distributions throughout the North Atlantic. (IMR)

During the period 13 August to 2 September 2007 field work with emphasis on instrumentation of minke whales was conducted in the waters between northern Norway and Svalbard, including the Bear Island. One minke whale was radio tagged in the Storfjord area southeast of Spitsbergen and followed for 116 hours. The area seemed to be a feeding area with several minke and fin whales present at the time. Within the area a satellite tag was also applied to a minke whale which was then followed for about three weeks. Biopsy samples were collected from minke (3), humpback (11), fin (12) and killer (1) whales. Several photo Ids were collected from humpback, minke, fin and blue whales. A VHF tag with suction cups was also tested on a humpback whale and stayed attached for about two hours. (IMR)

In August to September 2007 whale distributions were mapped during an ecosystem survey in the Barents Sea by having dedicated whale observers onboard who collected information following line transect protocols. (IMR)

During the traditional whaling season (April-October), body condition data and tissue materials for studies of DNA identity were collected from all minke whales taken by vessels participating in the Norwegian small type whaling. (IMR)

Studies of hypoxia tolerance of nervous tissue from hooded seals were conducted in collaboration with Dr. J. M. Ramirez of Department of Organismal Biology and Anatomy, University of Chicago, using in vitro electrophysiological recordings with thin slices from the cerebral (visual) cortex, as well as from the cerebellum. Analyses of the distribution of the neurally based respiratory protein neuroglobin and of selected enzymes in hooded seal neural tissue are conducted in collaboration with Dr. T. Burmester, Zoologisches Institut und Museum, Universität Hamburg, Germany. (UiT-AAB).

Immunohistochemical studies of the distribution of various connexin isoforms in the cardiac muscle of neonate and adult hooded seals were conducted at the Electron Microscopy Department, Institute of Medical Biology, University of Tromsø, by representatives of AAB (UiT-AAB).

Electron microscopic studies of organelles (mitochondria) in cerebral and cerebellar neurons and glial cells are conducted in collaboration with Dr. E. Messelt, Institutt for Oral Biologi, Universitetet i Oslo (UiT-AAB).

Marine mammals are hyperglycaemic compared to terrestrial mammals and hooded seals have plasma levels more than twice those of humans. Experiments are performed to study whether the hooded seal has developed more effective renal glucose reabsorption mechanisms due to the continuous high load of plasma glucose in the kidney. Various plasma glucose levels were experimentally established through intravenous glucose infusion in captive hooded seals, while urine flow and glucose concentration were measured continuously in order to determine threshold levels for plasma glucose to appear in urine. The reabsorption rate of glucose in proximal tubuli was also measured by use of radio labelled inulin in order to determine transport maximum (Tmax) for glucose in the hooded seal kidney (UiT AAB)

Pictures from aerial photographic surveys aimed to estimate the total populations of harbour seals along the coast of Norway have been analysed. (IMR)

To be able to adjust the estimates for animals not hauled out during aerial surveys, the haul-out behaviour of harbour seals has been investigated on special locations in Vesterålen and Rogaland – the collected data have been analysed. (IMR, NFH-UIT)

Determination of OH-PCBs and OH-PBDEs in plasma samples from polar bears (Ursus maritimus) and liver samples from 5 harbour seals was performed (NVH/VI). The seals were captured at Froan, Norway, in 2003 as part of EU-project FIRE, and provided by Eugen Sørmo at NTNU. Results showed, among others, that the levels of OH-PCBs were considerably lower in the seal liver samples compared to the polar bear plasma samples. 4’-OH-CB106, 3’-OH-CB138, 6-OH-BDE47 and 4’-OH-CB159 were not detected in any of the harbour seal liver samples. See Løken KBL, 2006 for further information.

Studies of a possible genetic bottleneck in walruses at Svalbard due to heavy hunting is done based on DNA extracted from old jaws (NHM, NP).

A study of the validity of the subspecies of Laptev walrus (Odobenus rosmarus laptevii) is performed by NHM and NP in cooperation with Greenland Institute of Natural Resources, Nuuk, National Environmental Research Institute, Rønne, Lund University, Lund, Zoological Institute, St. Petersburg. The analysis is based on DNA extracted from 12 old skulls of Laptev walrus, which is the only material available from that subspecies in the World. A manuscript, concluding that the Laptev walrus is a part of the Pacific subspecies, has been submitted for publication to BMC Evolutionary Biology. (NHM/NP)

Information on the sex distribution in the former catches of walruses in SE Svalbard is investigated by morphometric analyses of old jaws found. at the hunting sites (NHM, NP). The research is done in cooperation with Greenland Institute of Natural Resources, Nuuk, and Fisheries and Oceans, Winnipeg. The work has been published in Marine Mammal Science. The conclusion was that there was much more females in the area at that time than today. (NHM/NP)

Baseline data on serum chemistry parameters in Atlantic walrus from Svalbard has been investigated. Serum samples obtained from 17 males during tagging (NP) has been analysed for enzymes, proteins, metabolites, minerals and the hormone cortisol. This information will serve as reference values for the male population of Atlantic walrus in Svalbard, as well as for individuals in captivity. Together with similar data on other seal species, they may also represent important reference points for effects of environmental changes in the Arctic. The results have previously been presented at the 15th biennal conference on the biology of marine mammals, Greensboro, USA, 2003, and a scientific article is in preparation (NVH-SAV). 345

Seventeen walrus sera collected in 2002-2004 were tested for IgG antibodies against Toxoplasma gondii with the direct agglutination test with a cut off-value of 1:40 dilution. One sample was positive up to the highest dilution tested, 1:1280. (NVH-SAV)

Similar investigations have been conducted for 20 Weddell seals, 20 Ross seals , 9 crabeater seals and 61 Antarctic fur seals. A scientific article is in preparation (NVH- SAV).

Databases containing recapture information and incidental observations of marine mammals have been updated. (IMR)

Cetaceans Stomach content samples from minke whales have been analysed using traditional methods where the original biomass and size composition of prey items have been reconstructed based on remaining hard parts in the contents. (IMR, NFH-UIT)

Tissues sampled for stock identity studies of minke whales have been archived and analysed using DNA techniques. (IMR)

Databases containing incidental observations of marine mammals have been updated. Minke whale catch data for the 2006 and 2007 seasons have been computerised and evaluated. The work with cataloguing identification photos of humpback whales collected on incidental occasions and during our own surveys in Norwegian and adjacent waters is progressing. More recently, we have also collected identification photos from other species like minke whales, fin whales, blue whales and sperm whales. For the latter two species the usefulness in collecting such data is seen in connection with other established identification catalogues in the North Atlantic. (IMR)

As part of the work with mapping stock structure, migration and habitat use for humpback whales in the northeast Atlantic, DNA laboratory analyses of about 60 biopsy samples collected in Norwegian waters have been conducted in cooperation with P. Palsbøll at the University of Stockholm. Standard methods for population genetics studies will now be applied to the data. (IMR)

The past and present status of bowhead whales in the Northeast Atlantic are studied in a project cooperation between NHM, IMR, NP, and also in cooperation with Greenland Institute of Natural Resources, Nuuk, Wildlife Conservation Society, New York, and Fisheries and Oceans, Winnipeg. The population structure of bowhead whales during postglacial time is studied by help of DNA extracted from ancient (bones and baleen) and tissue from extant individuals. The material making the basis for the investigation is about 300 samples of bone remains found along the coasts of Svalbard and the Norwegian mainland. About 200 of these have been 14C dated are from recent to about 40,000 years old. Up to now parts of the mitochondrial DNA control region from about 200 individuals have been sequenced. Only minor differences in haplotype diversity have been found between the Spitsbergen and Bering Sea stocks. The results support previous findings suggesting that the BCB 346

NAMMCO Annual Report 2007 - 2008 stock retained a large amount of genetic variation despite the severe bottleneck caused by whaling around the turn of the 20th century. The similar haplotypes of the ancient Svalbard samples and the current BCB stock indicate significant migration between stocks. The results have been published in Molecular Ecology. (NHM/IMR/NP)

Biopsy samples of bowhead whales from western Greenland are analyzed in cooperation with Mads Peter Heide Jørgensen, Greenland Institute of Natural Resources and Lianne Postma, Fisheries and Oceans. (NHM) The mitochondrial cytochrome b (cytB) gene has been sequenced for a set of historic bowhead whales from Svalbard and compared to the highly variable control region haplotypes . Preliminary analyses show that the assignment of mitochondrial haplotypes on the basis of cytB sequences yields a significantly lower number but do not correlate to haplogroups based on control region sequences. The cytB based haplotypes occur at much higher frequencies and allow frequency-based comparisons of the genetic structure of bowhead whale stocks. (NHM) DNA suitable for PCR amplifications has been extracted from historic whale samples from South Georgia. Amplification and sequencing of two stretches of the mitochondrial cytb gene offers an easy and rapid approach to identifying samples suitable for further genetic analyses and to determine the species status of whale remains with reasonable confidence. At least for humpback, fin, and sei whales, South Georgia provides suitable material for studying historic population structures. A manuscript is under review in Marine Mammal Science. The project is done in cooperation with Tony Martin, BAS. (NHM).

2.5 Research results Pinnipeds Aerial surveys performed in the Greenland Sea in the period 11 to 29 March 2005 suggested a minimum hooded seal pup production of 15 200 (s.e. = 3 790, cv = 24.9%), i.e., considerably lower than observed in similar surveys in 1997. For this reason, in the period 14 March to 3 April 2007, new aerial surveys were performed in the Greenland Sea pack-ice (the West Ice), primarily to assess the pup production of the Greenland Sea population of hooded seals, alternatively also of harp seals if practicable possible. Two fixed-wing twin-engined aircrafts, stationed in Constable Pynt (East-Greenland), Akureyri (Iceland), and the Jan Mayen island, were used for reconnaissance flights and photographic surveys along transects over the whelping areas. A helicopter, operated from the applied expedition vessel (M/V”Nordsyssel”) also flew reconnaissance flights, and was subsequently used for other purposes, such as monitoring the distribution of seal patches and age-staging of the pups. The reconnaissance surveys were flown by the helicopter (14 – 24 March) and the fixed-wing aircrafts (21 march – 3 April) in an area along the eastern ice edge between 66°55’and 75°30’N. Obviously, the ice cover was narrow and the edge close to the Greenland coast in 2007, and all surveyed areas were overlaying the continental shelf (300 - 400 m depth). The reconnaissance surveys were adapted to the actual ice configuration, usually flown at altitudes ranging from 160 - 300 m. Repeated systematic east-west transects spacing10 nm (sometimes 5 nm apart) were flown from the eastern ice edge and usually 20-30 nautical miles (sometimes longer) over the drift ice to the west. The reconnaissance surveys detected no apparent hooded seal whelping concentrations, only scattered hooded seal families and, subsequently, solitary bluebacks over a relatively large area ranging from 72º00’N and 73º51’N. Scattered harp seal whelping was observed in the same area, whereas a more concentrated harp seal whelping patch was observed to the east of the scattered hooded seals between 73º00’N and 73º40’N. On 27 March, a total of 19 photo transects were flown over the entire area of scattered whelping hooded seals, including also scattered whelping harp seals in the northern parts of the covered area. The survey was conducted with low-density photographic effort, resulting in a total of 1136 photos. On 29 March, a high-density coverage of the concentrated patch of whelping harp seals was conducted, resulting in a total of 1987 photos shot. A second, smaller harp seal whelping concentration further south was covered in another high-density coverage on 3 April, resulting in a total of 264 photos shot. Only very few whelping hooded and harp seals were observed outside the surveyed whelping areas. The results from the aerial surveys are now being analysed and will be used to estimate the 2007 hooded and harp seal pup production in the West Ice. Subsequently, the status of the stocks will be assessed by fitting population models to the pup production estimates. (IMR) 348

NAMMCO Annual Report 2007 - 2008

During aerial surveys to estimate hooded seal pup production in the West Ice in 1997, additional video material was collected from helicopter surveys. This material have now been analysed and the conclusion has been drawn that no additional information could be gained from it, as it had a lower coverage and lower resolution than ordinary still photos. In addition, by the methods available, reading video tapes requires a lot of effort. Results from the standard aerial photo analyses have been presented earlier. (IMR)

A Canadian-Norwegian genetic study has been conducted of the two putative populations of hooded seals in the North Atlantic. The Greenland Sea population pup and breed on the pack ice near Jan Mayen (‘West Ice’) while the Northwest Atlantic population is thought to breed in the Davis Strait, in the Gulf of St. Lawrence (the ‘Gulf’), and off southern Labrador or northeast Newfoundland (the ’Front’). Microsatellite profiling of 300 individuals using 13 loci and mitochondrial DNA sequencing of the control region of 78 individuals was carried out to test for genetic differentiation between these four breeding herds. No significant genetic differences were found between breeding areas, nor was there evidence for cryptic or higher level genetic structure in this species. The Greenland Sea breeding herd was genetically most distant from the Northwest Atlantic breeding areas; however the differences were statistically non-significant. These data, therefore, suggest that the world’s hooded seals comprise a single, panmictic genetic population. (IMR)

In a Norwegian-Russian study of harp seal genetics (DNA-based), a 421 bp sequence from the mitochondrial control region has been sequenced in 21 seals sampled in the White Sea breeding patches and 28 harp seals sampled in the West Ice breeding patches. Preliminary analyses show extremely high diversity and no significant differentiation between areas. Additional samples from 53 West Ice harp seals and 78 White Sea harp seals have been processed but are not yet analysed. Fragment analyses based on eight microsatellites are in progress. (IMR)

Work with a historical population assessment of Barents Sea harp seals back to the late 1800s has been finished. (IMR)

Historical Norwegian and Russian data which describe the trends in fertility rate and maturity at average age (MAM) for hooded seals in the Greenland Sea have recently been subjected to joint Russian-Norwegian analyses. Age at maturity was determined by fitting Richards’ curves to age specific proportions of mature females in scientific samples taken by Russian scientists in the Greenland Sea pack ice in May-June in the years 1990-94. Samples from the Denmark Strait (1956-60) and South Greenland (1970- 71) previously analysed by the back calculation method were also included in the present analyses. Although there were annual difference in MAM among the Greenland Sea samples a common MAM of 4.8 years could be fit to all years. Similarly, a common MAM of 3.1 year could be fit to the two Northwest Atlantic samples. This represents a temporal and a stock specific split in the sample and it cannot be concluded which factor is more important. Ovulation rates of mature females ranged from 0.68 in May 1990 to 0.99 in June 1991 and 1992, but the average ovulation rate of 0.88 was similar to previous estimates for Northwest Atlantic hooded seals. For breeding and moulting patch samples taken in the period 1986-1990, indirect measures of pregnancy rates derived 349

Norway – Progress Report Marine Mammals from patterns of alternation in corpora formation between ovaries ranged from 0.74 to 0.97 and were significantly lower in 1987 and 1988 than in all other samples including the older data for the Northwest Atlantic stock ranging from 0.94 to 0.97. (IMR)

Biological parameters (fertility, mortality, demography) are important input in models used for seal assessments. Data availability is, however, restricted, and it is important to establish routines for sampling. A substantial material of teeth (for ageing) has already been sampled, both by Norway and Russia, from commercial catches. This material is very useful, and some joint Norwegian-Russian age-reading experiments have been conducted on harp seal teeth. Age estimates of known age teeth (obtained from mark- recapture experiments) suggested differences between readers in both accuracy and precision, but these were not found to be statistically significant. Overall the study indicates that age estimates of harp seals should be treated as probability distributions rather than point estimates even in the youngest age classes. Adequate description of the probability distributions and the effects of having different readers can only be achieved by repeating the experiment with a much larger sample size. To obtain this, and to try to standardise reading between laboratories (in Norway, Russia and other relevant countries such as Canada and Greenland), a joint workshop was arranged in Bergen, Norway in November 2006. (IMR)

To enable an assessment of the ecological role of hooded seals throughout their distributional range of the Nordic Seas (Iceland, Norwegian, Greenland Seas), a project was initiated in 1999 by members of the NAMMCO Scientific Committee where the feeding habits of the species were studied in 1999-2003. The project pays special attention to the period July-February (i.e., between moulting and breeding), which is known to be the most intensive feeding period for hooded seals. Seals were collected for scientific purposes on expeditions conducted in the pack ice belt east of Greenland in September/October 1999, 2002 and 2003 (autumn), July/August in 2000 (summer), and February/March in 2001 and 2002 (winter). Results from analyses of stomach and intestinal contents revealed that the diet was comprised of relatively few prey taxa. The squid Gonatus fabricii and polar cod Boreogadus saida were particularly important, whereas capelin Mallotus villosus, and sand eels Ammodytes spp contributed more occasionally. G. fabricii was the most important food item in autumn and winter, whereas the observed summer diet was more characterized by polar cod, however with important contribution also from G. fabricii and sand eels. The latter was observed on the hooded seal menu only during the summer period, while polar cod, which contributed importantly also during the autumn survey, was almost absent from the winter samples. During the latter survey, capelin also contributed to the hooded seal diet. Samples obtained in more coastal waters indicated a varied, fish based (polar cod, redfish Sebasetes sp., Greenland halibut Reinhardtius hippoglossoides) diet.

In 2001 and 2002, Norwegian and Russian scientists performed an aerial survey to assess whether there was an overlap in distribution, and thus potential predation, between harp seals and capelin in the Barents Sea. This experiment is now being followed with boat- based surveys aimed to study pelagic feeding by harp seals in the Barents Sea during summer and autumn. In May/June 2004, in June/July 2005, and in May/June 2006, Norwegian surveys were conducted, aimed to study the feeding habits of harp seals 350

NAMMCO Annual Report 2007 - 2008 occurring in the open waters of the Barents Sea. Very few seals were observed along the coast of Finnmark, and no seals were seen in the open, ice-free areas. In the northwestern parts of the Barents Sea, however, very large numbers of seals were observed along the ice edge and 20-30 nautical miles south of this. In these areas, 33, 55 and 57 harp seals were shot and sampled (stomachs, intestines, blubber cores) in 2004, 2005 and 2006, respectively. Additionally, samples of faeces were taken from the haul out sites on the ice. Preliminary results from the analyses indicate that the summer consumption to a large extent was dominated by krill, whereas polar cod also contributed importantly. All sampling were performed in a period with low capelin abundance – this may have influenced the results. (IMR, NHF-UIT).

During research surveys in the Greenland Sea pack ice in 1999-2002, blubber and muscle tissues were secured from captured harp and hooded seals. The sampled tissues were used for analyses of fatty acid profiles and stable isotopes. The application of fatty acids analysis combined with stable isotopes in food web studies in marine ecosystems is an efficient tool, as it reflects dietary intake and assimilation over longer time periods than stomach content analysis. The use of fatty acid trophic markers (FATM) to trace the energy transfer from phytoplankton to top predators is based on the observation that primary and some secondary producers synthesize characteristic fatty acids and that this fatty acid signal is conservatively transferred through food chains. Stable isotopes reveal information about food carbon sources and trophic position of the species. The stable isotopes ratios of carbon and nitrogen (δ13C and δ15N) in consumer proteins and fatty acid signature in consumer lipids both reflect those of their prey. Even if the two seal species showed considerable overlap in diet and occur at relatively similar trophic levels, the fatty acid profile indicated that the base of the food chain of harp and hooded seals was different. The fatty acids of harp seals originated from diatom based food chain, typically for high Arctic ice covered ecosystems. The fatty acids of hooded seals originate from dinoflagellate and the prymnesiophyte Phaeocystis pouchetii based food chain, which associates this species with more open Atlantic waters ecosystems.

Harp seals predatory interactions were incorporated in the assessment model of capelin (Bifrost) in 2007. Bifrost, in which species are structured by age, length and maturity, can potentially serve as a simulator where the herring-cod-capelin harvesting control rules can be studied. Presently, the predation on cod and capelin by harp seals has been included in the model. Preliminary results indicate that harp seals have considerable impact on the capelin stock. By running two harp seal abundance scenarios, one when the stock being constant at the present level and another when the stock being constant at 50% of the present level, indicate that the maximum long-term catch of capelin is sensitive to number of harp seals in the Barents Sea; a reduced harp seal population generated a 100% greater maximum long-term catch of capelin. (IMR)

Seals are high trophic level feeders that bioaccumulate many contaminants to a greater degree than most lower trophic level organisms. In 1999 and 2000, harp, hooded and ringed seals were captured on the east coast of Greenland for scientific purposes, including documentation of the levels and bioaccumulation potential of radiocaesium. The results indicated low levels of radiocaesium in all seal species in response to a long term trend of decreasing levels of radiocaesium in the Greenland Sea region. 351

Norway – Progress Report Marine Mammals

Bioconcentration factors for the seals corresponded well with the variety of prey consumed by them in the region, indicating that diet selection is a dominant factor controlling bioaccumulationm of radiocaesium in these Arctic seals. (IMR)

Immune-histochemical studies of neural tissue from hooded seals have revealed an unusual distribution of both neuroglobin and mitochondria, compared to in rats and some other non-diving species. This finding and its functional significance is presently studied using electron-microscopical and immune-histochemical techniques (staining for various metabolic enzymes), based on previously collected fixed material, as well as electrophysiological studies of fresh material. Simultaneously, the hooded seal neuroglobin has been sequenced, revealing some unique amino-acid substitutions compared to in several other species. The possible functional significance of these substitutions is as yet unclear, and will be subject of further studies (UiT-AAB).

Electron-microscopical studies of hooded seal hearts and the distribution of the gap junction protein connexin showed that commercially available connexin-antibodies for connexin-isoforms like connexin43 (Cx43) and Cx 45 bind specifically to hooded seal cardiomyocytes, both in pups and adults. Cx43 appears to occur in higher density in adult seal cardiomyocytes than in pups, but results are preliminary and further studies will be required in order to determine whether the high hypoxia tolerance of the pinniped heart may somehow be linked special adaptations in cardiac gap junction function (UiT-AAB).

Electrophysiological, immune-histochemical and electron microscopical studies of neural tissue from hooded seals have been continued during 2007 in order to shed light on possible mechanisms underlying the unusual neuronal hypoxia tolerance of this species. Unlike in rats and some other terrestrial mammals, both neuroglobin and mitochondria seem to be predominantly found in glial cells, and much less in neurons, in hooded seals. This may suggest that seal neurons are designed for efficient anaerobic metabolism, which may in part explain their enhanced hypoxia tolerance. Further studies are, however, required before firm conclusions may be drawn (UiT-AAB).

Preliminary results obtained from studies of hooded seal kidney physiology suggest that the renal threshold for glucose is more than twice that of humans, which indicates that the seal kidney has a higher transport maximum (Tmax) for glucose and, thus, a higher capacity for reabsorption of filtrated glucose, thereby avoiding losing glucose through urine (UiT-AAB)

One recently weaned hooded seal pup was tagged with a satellite-linked dive recorder in the last week of March 2006 in the pack ice of the Greenland Sea. The transmitter provided data on daily locations and dive behaviour (dive depths, dive durations and time at depth) for a total of 4 weeks, before contact was lost for unknown reasons. During these initial weeks of life, the pup remained in pack-ice covered waters, and appeared to drift passively with the pack ice in a south-westerly direction, towards the Denmark Strait. In 2007 four recently weaned hooded seal pups were tagged with satellite-linked dive recorder in the last week of March in the pack ice of the Greenland Sea. The transmitters provided data on daily locations and dive behaviour 352

NAMMCO Annual Report 2007 - 2008

(dive depths, dive durations and time at depth). The pups entered water shortly after tagging, to perform extensive migrations in the Northeast Atlantic during the course of the spring/summer autumn of 2007. Three of the animals traveled from the tagging site (the pack-ice NE of Jan Mayen) to waters north of the Shetland Islands, from where two continued due north to waters west and north of Svalbard. At this time, the fourth animal already stayed in this area, after first having visited the shelf edge west of Bear Island. Contact was lost with all animals in October 2007. During the course of the tracking period, the animals performed dived to depths exceeding 300 m. Data on distribution and diving behaviour are currently being analysed (UiT-AAB).

Abundance estimation surveys were performed for harbour seals from the Swedish border to Finnmark county in August-September (i.e., the moulting period, methodology based on total counts) in 2003-2006. Almost all known moulting areas were covered by aerial photographic surveys using a fixed-wing aircraft. In some sub- areas, two or three independent surveys were conducted in the same year. In addition, visually counts using binocoulars from smaller boats and islands were carried out in some selected areas. The surveys revealed a total minimum population of c 6700 harbour seals in Norwegian waters. The seals were most abundant in the Nordland and Sør-Trøndelag counties with minimum estimates of approximately 2500 and 1500 harbour seals, respectively. The present minimum estimate was approximately 700 seals lower than the estimate obtained in a similar study in 1996-1999. Both studies covered the same areas and used mainly the same type of aircraft, and the same camera. Increased hunt along the entire coast and the phocine distemper virus (PDV) epidemics in the Skagerrak region in 2002, could have contributed to the lower present estimate. (IMR)

The haul-out behaviour of harbour seals has been investigated on a location in Vesterålen, Nordland county, during moult (August) in 2003 and 2004. The studies were carried out using VHF telemetric equipment. The purpose was to obtain necessary data for estimation of a correction factor to account for unobserved animals in aerial photographic surveys and visual counts. The data were processed using various time series analysis techniques. First, a smoothed estimate of the proportion of seals that haul-out was obtained using thin-plate regression splines in a GAM framework. Furthermore, in order to get some deeper knowledge about the behaviour of the seals, a multiscale analysis tool were applied in order to visualize the haul-out pattern at different time scales. The results of the time series analysis show that the main proportion of the hauled-out seals was in the range of 0.2 – 0.5 of pups and subadults at low tide, and that the sea level predicts the proportion of seals better than the sun elevation. The observed proportions in the present study are comparable with results from studies in other harbour seal populations. (IMR)

A pilot study aimed to assess the prey consumption by harbour seals in the Gavlfjord in Vesterålen, and to evaluate the seal consumption in relation to the major fish resources in the area, was started in 2007. Recently developed GPS-GSM tags were deployed on 5 harbour seals late August 2007. These tags collect and relay data (on dives, haulout, positions, and two-hour summary data) at a much higher temporal resolution and spatial accuracy than can be obtained from conventional satellite tags. 353

Norway – Progress Report Marine Mammals

Scat samples, aimed to estimate the diet composition of the seals, have been collected during summer and autumn. The data will be combined with population estimates, and the energetic demand of seals to predict total annual consumption by species. Acoustic and trawl based resource surveys were carried out in January-February and June, and will be continued in January 2008. The tags were supposed to work for 4-6 month, and data were still obtained from 3 deployments by December 2007. (IMR)

A method has been developed that could be used to estimate the abundance of grey seals from pup counts performed at one or a few surveys per season. Using this method requires data input on statistics on the lengths of well-defined morphological pup “stages”. To provide such data was the main objective of a project conducted in Norwegian and Russian grey seal breeding colonies in October-December 2005. In each colony, newborn seal pups were observed from an inflatable boat, and researchers landed where the pups were observed. Pups were caught, tagged with Dalton jumbo Rototags, and their sex recorded. In subsequent daily visits to the sites, the developmental stage was monitored on each individual pup. The pups were classified into six morphological stage categories (including newborn), and the duration of each stage (mean and standard deviation in days) was the main parameter to be estimated. Approximately 80 and 100 pups were followed in Norway and Russia, respectively. For various reasons (mobility of pups and lowered monitoring frequency to minimise disturbance) both the Norwegian and the Russian stage monitoring expeditions had very few full stage development sequences (i.e. from birth to stage 5). The number of high quality partial sequences (with observation based start and end for individual stages) ranged from 3-18 individuals. Based on this material median stage duration lengths were derived from both Norway (Myken, Northern Norway) and Russia (Ainov, Northwest Russia) for 4 stages (based on Radford, 1978; excluding stage 5). Median stage durations varied from 4 to 6 days in Myken and from 4-8 days in Ainov but there was considerable variability within most stages. There was a tendency towards longer duration of stage 1 and 2 in Myken as compared to Ainov, whereas stage 3 and 4 appeared to be of longer duration in Ainov than in Myken. The classification of stage 2 and 3 depend very much on body condition (stage 2 has a clearly defined neck, while stage 3 hasn’t ) and these characteristics could thus vary both between years and between geographical regions depending on variability in resource availability. Differences in stage duration between areas were marginally significant for stages 1 and 3 (P< 0,05, Mann Whitney U-test with Dunn-Sidak correction for multiple comparisons). Analyses of the data continue and will include analyses of differences in stage classifications between observers based on digital images, durations of pooled stages and simulation studies of the effect of stage length variability and detail on population modelling. (IMR)

In 2001-2003, ship based surveys of grey seal pup production were conducted along the Norwegian coast, which resulted in a total minimum estimate of c 1200 grey seal pups born annually in Norwegian waters. By using a range of multipliers (4.0-4.7), based on annual growth rates of 7-12 % in other grey seal populations, it was estimated a total abundance of approximately 4600-5500 grey seals (1+) in Norwegian waters. A new study aimed to cover the entire distribution area of grey seals in Norway in the period 2006-2008, was started in Troms and Finnmark in November- 354

NAMMCO Annual Report 2007 - 2008

December 2006. Ship based surveys of grey seal pupping areas counties were carried out, and the results revealed and increase in the number of pups born in both counties. In Troms, 76 pups were born in 2006 compared to 41 pups in 2003. In Finnmark, 207 pups were counted in 2006 compared to 169 pups in 2003. Total population estimates were derived from the recorded pups born using a range of multipliers (4.0-4.7), based on observed annual growth rates of 7-12 % in other grey seal populations. This resulted in a total estimate of c 1200 (1130-1330) one year and older (1+) grey seals in 2006 in the management area which cover Troms and Finnmark counties, compared to c 900 (840-990) grey seals (1+) in 2003. (IMR)

In September-October 2007, similar grey seal pup surveys were carried out in the entire area between Lofoten in Nordland county and Froan in Sør-Trøndelag county. In sub-areas, also aerial fixed-wing photographic surveys were conducted. At present no results are available. Due to difficult weather conditions, the Lofoten area has to be surveyed also in 2008.. Also the grey seal population in Rogaland county will be surveyed during November-December 2008. (IMR)

Studies of grey seal population structure based on 389 bp sequence of the mitochondrial control region show clear differentiation between grey seal populations in Norway, the Orkney Islands and the Baltic Sea based on AMOVA analysis. Within Norway, there are at least three clearly differentiated grey seal populations in southern, central and Northern Norway. Exact tests of pairwise differences between populations show highly significant differentiation on an even finer geographical scale along the Norwegian coast with breeding colonies in the Helgeland and Troms forming separate units. Fragment analyses based on 8 microsattellites are ongoing. (IMR)

The brominated flame retardant hexabromocyclododecane (HBCD) was analysed in two marine food webs from Norway (Bæk et al., 2006). The species were collected in 2003-2004. The HBCD are determined in different species from Svalbard and outer Oslofjord. From the outer Oslofjord: polychaete lugworm (Arenicola marina), calanoid copepods (Calanus spp), glass shrimps (Palaemon adspersus/P.elegans), northern shrimp (Pandalus borealis), black goby (Gobius niger), sandeel (Ammodytes spp.), sand goby (Pomatoschitus microps/P. minutus), saithe (Pollachius virens), whiting (Merlangus merlangus), Atlantic cod (Gadus morhua) and harbour seals are analysed. From Svalbard we have analysed ice-amphipod (Gammarus wilkitzkii) polar cod (Boreogadus saida), ringed seal and polar bear (Ursus maritimus). The main findings were that HBCD biomagnifies in the food chain up to ringed seal. There was not found biomagnifications any from ringed seal to polar bear. (NVH/VI)

Polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD) were analysed in a food chain at Svalbard (Sørmo et al., 2006a). The higher trophic sampling included polar cod (Boreogadus saida), adult male ringed seals and the polar bear (Ursus maritimus) Invertebrates, polar cod and ringed seals were sampled in 2002-2003 north of 78°N. In the ringed seal, the biomagnification of BDE-47 from polar cod to ringed seal was ~200 times, whereas concentrations of BDE-28, -99, - 100, 154 and HBCD showed more modest 20 to 85 times biomagnification from polar 355

Norway – Progress Report Marine Mammals cod. BDE-209 showed no biomagnification in the seals, and was also only detected in one seal. Thus, in contrast to the modest biomagnification of BFRs in the lower parts of the Arctic marine food web (from invertebrates to fish), there was a more than two orders of magnitude biomagnification of many BFRs from pelagic zooplankton and polar cod to the ringed seal. (NVH/VI)

Grey seal pups were sampled in Norway (n=37) and Estonia (n=53). See Sørmo et al., 2006b. Immunotoxicity of polychlorinated biphenyls (PCBs) and dichlorodiphenyl-trichloroethans (DDTs) in free ranging grey seal pups from Atlantic and Baltic waters was studied. (NVH/VI)

BFRs (PBDEs and HBCD) were analysed in an arctic marine food chain: polar cod, ringed seals, and polar bears. 6 ringed seals were captured in 2003. For results, see Sørmo et al., 2006c. (NVH/VI)

Within the European project FIRE, the presence of the major BFRs (PBDEs, TBBPA and HBCD) was identified and characterized in marine biota from the Artic (Spitsbergen, Bear Island) to the Norwegian west coast (Froan), Skagerrak, Dutch Wadden Sea and the Western Scheldt estuary (NL). The species included among others tern, harbour seals and polar bear. Results showed that the concentrations of PBDEs in mature male harbour seals from the outer Oslofjord were in the same order of magnitude as the concentrations in mature male harbour seals from the Wadden Sea (Figure 2). This pattern was also seen for HBCD, levels in harbour seals were lowest at Svalbard, followed by seals from Froan, and highest in the Oslofjord and Wadden Sea. The HBCD levels in Oslofjord and Wadden Sea are about one order of magnitude higher than in the seals from Spitsbergen (Pim Leonards et al., 2007.).

In June – July 2002 and 2004 a total of 29 Cape fur seals were captured in 3 colonies in Namibia and equipped with satellite transmitters. Their movements were followed until pupping and breeding in December. The Cape fur seals performed foraging trips lasting 4-7 days and covering 180 – 430 km, and spent around 2 days on shore between the foraging trips. Fidelity to colony and foraging trip length varied significantly between colonies. Seals from Atlas Bay in southern Namibia and Cape Cross in central Namibia moved frequently between colonies along the coast and visited numerous foraging areas performing both long (5-7 days, outside Atlas Bay) and short foraging trips (4-5 days, in central Namibia). Seals in the northern Cape Frio colony performed predominantly long trips (7 days) and showed high fidelity to both colony and foraging areas. The higher degree of fidelity observed in Cape Frio seals, both to foraging areas and to the colony, suggest a greater persistence and predictability of prey, and thus a better habitat quality, in this region compared to southern and central Namibia. This is further supported by a larger increase in pup production in northern Namibia relative to southern Namibia. Furthermore, although males tended to perform longer foraging trips and foraged at deeper depths than females, there was an extensive overlap between the two sexes at sea. Thus, intraspecific competition, believed to be a key factor in causing sexually segregated distributions at sea in several fur seal species, seem not to be an important factor affecting Cape fur seal distributions. The flexible behaviour of Cape fur seals 356

NAMMCO Annual Report 2007 - 2008 observed in this study may be an adaptation to the highly dynamic northern Benguela upwelling system, and perhaps a precondition for the rapid recovery of Cape fur seals following the dramatic events of sealing and Benguela niños that killed thousands of seals. (IMR)

Baseline data on 24 different serum chemistry parameters in Atlantic walrus, Weddell seal, Ross seal, crabeater seal and Antarctic fur seal have been obtained and will be presented by median-values, range and 10%-90% percentiles in two scientific articles (NVH-SAV).

Cetaceans In 2007, an age-length structured multispecies model (Gadget, Globally applicable Area-Disaggregated General Ecosystem Toolbox) was parameterised for the Barents ecosystem in order to analyse the historic population dynamics of major fish and marine mammal species. Presently, minke whale is the only sea mammal included in the model but incorporating harp seals predatory interactions in the model will be an important task in the future. There are, however, not sufficient data available on harp seal diet to parameterize a MSFR. The model was used to examine possible effects of a number of plausible biological and fisheries scenarios. The results suggest that changes in cod mortality from fishing or cod cannibalism levels have the largest effect on the ecosystem, while changes to the capelin fishery had only minor effects. Alternate whale migration scenarios had only a moderate impact on the modelled ecosystem. Indirect effects are seen to be important, with cod fishing pressure, cod cannibalism and whale predation on cod having an indirect impact on capelin, emphasising the importance of multi-species modelling in understanding and managing ecosystems. Models such as the one presented here provide one step towards an ecosystem based approach to fisheries management. (IMR)

The Norwegian DNA register for minke whales has been further studied to investigate stock structure. Although some heterogeneity can be found, no significant differences are apparent between the Small Areas within the North-eastern management area. (IMR)

Based on statistics collected in connection with the minke whaling, growth of minke whale fetuses and birth periods for minke whales in the North Atlantic have been studied in a master thesis (2006). With a pregnancy period of about 10 months, mating mainly takes place in March-April and calving in January-February. Based on mating time, North Atlantic minke whales seem to group into three geographical clades – one that comprises the North Sea, Iceland, Jan Mayen and Svalbard; one which comprises the Norwegian Sea and the Barents Sea, and one which comprises Canada and Greenland. Mean estimated length at birth falls into two groups – one comprises the Barents and Norwegian Seas and Svalbard, and one comprising the rest. (IMR)

Abundance estimates for fin, sperm and humpback whales based on recent surveys have been provided earlier, however, in 2006 some studies were done on bias in fin whale estimates attributed to g(0) deviating from 1. It was shown that this effect on fin whale estimates based on data from the Norwegian surveys was minor. (IMR)

During the years 2003-2006, five minke whales have been tagged in the Norwegian Sea and Svalbard areas to increase the data base of surfacing rates for use in estimation of abundance of minke whales in the Northeast Atlantic. While one of the whales was followed for less than 3 hours, the other four were followed over periods of 19-40 hours. They showed large individual variation in hourly blow rates, which is of the same order of magnitude as variation between individuals, and spans the range 33-72 blows/whale/hour. These are in accordance with results from earlier radio- tagging and visual experiments. The mean intersurfacing interval of 18 minke whales radio-tagged in Norwegian waters is 77.31 s, corresponding to a blow rate of 46.6 blows/whale/hour. A statistical model for successive dive times of North-eastern minke whales has been developed with the aim of describing the variability in the short term dive patterns between whales as well as within the whale over longer time periods. The dives were divided into short, medium and long dives. It was found that the series of rapid blows were not very dependent on the longer dives which may mean that the minke whales operate well beyond their theoretical diving capacity based on body size. It was also found that the variability in the conditional probability of a dive being long given that it is not short was considerable both between and within whales, and roughly of the same magnitude. (IMR)

Killer whales staying in the Norwegian spring spawning herring overwintering area in Vestfjorden, northern Norway, have been studied by means of photo identification for many years. Using mark-recapture estimators, the local population in Vestfjorden was estimated to be about 600 animals in 2003. Reproduction rate seems to be low as the calving interval ranged from 3 to 14 years. (IMR)

A study based on historic catch positions, incidental observations and dedicated sightings surveys, indicates that although some of the killer whale populations in the northeast Atlantic undoubtedly follow the migrations of the Norwegian spring spawning herring, this is not a general rule. Estimates of abundance show an interannual variability from about 5,000 to 25,000, probably caused by difficulties in group size estimation and differences in area coverage between surveys. (IMR)

A study of humpback whales in the northeast Atlantic based on incidental sightings, ecosystem surveys, sightings surveys and photo identification work indicate that the abundance of humpback whales in the Barents and Norwegian Seas combined is around 1,000 animals in mid-summer and there is no statistical evidence of an increase over the years. However, summer distributions have varied between surveys with the year 1995 as the most extreme with a major part of the animals sighted around the Bear Island. Prior to 1995 most humpbacks were sighted in the Norwegian Sea, while post 1995 sightings are more widespread and also include many observations in the eastern part of the Barents Sea. Photo identification work has been carried out within the season July – September in waters surrounding the islands Jan Mayen, Bear Island and Hopen. Resightings, within year or up to eleven years after first sighted, were within the same general areas as the first sight, indicating strong site fidelity for this season. There was one exception in this material, demonstrated by one individual 358

NAMMCO Annual Report 2007 - 2008 which was seen at Jan Mayen in August 1997 and off Bear Island in July 2003. For data collected over the years 1992-2003, the average distance between resightings is 134 km (SD = 175 km), and in a sight-resight pair, there is a tendency that the latest dated position is farthest to the north and east, indicating a general movement in late summer to fall in a northeastern direction. (IMR)

Since 2003 marine mammal observers have participated on ecosystem surveys in the Barents Sea conducted in August-October. In addition to marine mammal distributions, these surveys provide information on ocean climate and distribution of water masses, and abundance and distribution of pelagic fish. During these surveys 11-18 species of marine mammals are observed each year, and of these white-beaked dolphins Lagenorhynchus albirostris, common minke whales, fin whales and humpback whales are most frequently observed. The distribution of these species within the Barents Sea differs. Humpback and fin whales are predominantly observed along the shelf edge, in the deeper troughs around Bear and Hopen Islands and in the northern Barents Sea. White-beaked dolphins and common minke whales occur throughout the Barents Sea, although the white-beaks have high density areas south of the high density areas of the baleen whales. While the smaller and rapid white-beaked and minke whales have dynamic distributions changing from year to year, the larger whales, and particularly the humpback whales, have conservative distributions that are similar between years. (IMR)

Predators aggregate where prey is available, a process termed the predators’ aggregative response. Therefore, systematic spatial concordance between predators and potential prey species is a good indicator of predator-prey interactions. In the Barents Sea, the different prey species have different spatial distributions; polar cod in the north and east, capelin in the central areas, herring in the south and the newcomer, blue whiting in the south-west. And furthermore, within these prey species, also the different age groups differ in distributions. In capelin, for instance, the older capelin is distributed further north and east than the younger capelin, at the time of the ecosystem cruise. Thus, within the Barents Sea, we can use the aggregative response to investigate both which prey stocks the cetaceans are targeting, as well as which demographic part of the stocks. Humpback, fin and minke whales aggregate in the north where 2-year old capelin is abundant. During the years covered the capelin stock has been small but increasing, and 2-year olds have been more abundant than older capelin. White-beaked dolphins are associated with 1-year old capelin. Furthermore, white-beaked dolphins and fin whales were also associated with blue whiting. It is interesting to note that none of these species were associated with juvenile herring, which could have been an alternative prey during periods of low capelin abundance. Krill may therefore be more important as alternative prey, but we have insufficient data on krill distributions to test this hypothesis.

Finally, annual abundance indices of humpbacks within the Barents Sea are identical to annual changes in capelin abundance. No such correlation is observed between the other three cetacean species and prey abundance. We suggest that the number of humpback whales immigrating to the humpback core areas is regulated by the

359

Norway – Progress Report Marine Mammals amount of food within these areas, while the other cetacean species respond to changes in food availability by tracking different prey species, which result in the dynamic spatial distributions of these species. (IMR)

Biopsy samples of white whales sampled at Spitsbergen (captured in 1995-1997) were analysed for toxaphenes (VI/NVH). Results (Andersen et al., 2006) showed that concentrations of sum toxaphenes in white whale blubber (biopsies) (11,447 ng/g lipid weight (lw)) were 2.5 times higher than the mean concentrations of sum DDTs and sum PCBs, and 4.5 times higher than sum chlordanes measured earlier in the same individual white whales.

3. ONGOING (CURRENT) RESEARCH

Harp and hooded seal pup productions were assessed in the Greenland Sea in 2007. In 2008, analyses of the data collected during this survey will be finalized and new abundance estimates will become available. (IMR)

Sampling of data on body condition, reproduction and health status from harp seal 1yr+ animals taken in commercial catches will be performed on one Norwegian vessel operating in the Greenland Sea in April-May 2008. Similar data will be secured from Greenland Sea hooded seals during research cruises in April and July 2008. (IMR, NVH-SAV)

Satellite tagging experiments with harp seals in the White Sea will be carried out jointly between Norwegian and Russian scientists with the purpose to study distribution, migrations and daily activity of the seals. This activity (supposed to run over a period of 5 years with new taggings every year) will give an important contribution to a better understanding of the temporal and spatial distribution of the seals, which is important input data when their total consumption of marine resources in the Barents Sea is to be assessed. It is important that animals of different sexes and ages are tagged. Each tagging will include 15 tags being deployed every spring (i.e., immediately after the moulting period). First deployment of tags will be conducted in the White Sea in 2008. (IMR)

During the period September-November 2008, ship based registrations of grey seal pups, including tagging, counting and staging of pups, will be conducted in Lofoten and Southwest Norway – this is the third of a three year program aimed to provide a new abundance estimate for the species along the entire Norwegian coast from Rogaland county in the south to Finnmark county in the north. All known and many other potential whelping areas along the Norwegian coast will be surveyed. (IMR)

Ecological studies designed to provide data on habitat use, diet and food consumption of harbour seals will be conducted in North Norway. A number of seals are already fitted with GSM/GPS tags – feaces sampling and resource mapping in the observed distributional area of the seals will be conducted in the period February-October. (IMR, NFH-UIT) 360

NAMMCO Annual Report 2007 - 2008

Possible methods are being developed in order to able a relatively quicker toxic screening of marine mammal products, especially with regard to the monitoring of TEQ (toxic equivalent factor) concentrations. (VI)

4. CATCH DATA

Sealing Four Norwegian vessels participated in the commercial harp and hooded seal catches in the West Ice (the Greenland Sea) both in 2006 and 2007. In the East Ice (the southeastern Barents Sea) two vessels operated in 2006, one in 2007. Harp seal quotas were permitted taken as weaned pups subject to prescribed conversion factors between pups and 1+ animals, the hooded seal quota in 2006 was given irrespective of age. Due to uncertain status for the Greenland Sea hooded seals, no animals of the species were permitted taken in the ordinary hunt operations in 2007. Only a few animals were taken for scientific purposes. Table 1. shows the Norwegian catches of harp and hooded seals in 2006 and 2007. The total given quotas were not fulfilled in any area: In the West Ice, 7% of the harp seal quota and 91% of the hooded seal quota were taken. In the East Ice and the White Sea 16% of the quota was taken (including Russian catches of 7,005 pups and 102 1+ animals).

Whaling After a temporary suspension, the traditional small type Norwegian minke whaling was again permitted in 1993 and quotas were implemented based on the Revised Management Procedure (RMP) developed by the International Whaling Commission's (IWC) Scientific Committee. The RMP allocates catch quotas to specific management areas. There are five such management areas within the region of interest to Norwegian whalers, and these were revised by the IWC/SC at their Implementation Review of North Atlantic minke whales conducted at the 2003 Annual Meeting. Starting in the 2004 season, the areas are (1) the Svalbard-Bear Island area (coded ES), (2) the eastern Barents Sea (EB), (3) the Norwegian Sea and coastal zones off North Norway, including the Lofoten area (EW), (4) the North Sea (EN) and (5) the western Norwegian Sea-Jan Mayen area (CM). Table 2. shows the number of minke whales taken by area in the 2006 and 2007 seasons. Since the quotas are given by five- year blocks, catches may deviate from quotas within year. 361

5. BY-CATCH DATA

2006 Norwegian Fisheries are comprehensive and include a large number of vessels and gear types. Further information on catch and effort can be found on http://www.fiskeridir.no/. With regard to volume landed, most of the pelagic catches were by purse seine, and the demersal catches by demersal trawl. These gear types operated by the larger vessels are regarded as having a relatively low risk for by- catches of marine mammals in Norwegian fisheries. Monitoring of by-catches in the offshore fleet continued in 2006 using two different approaches: 1) onboard independent observers from the Directorate of Fisheries and 2) ten vessels contracted by IMR to report detailed statistics of effort, catches and by-catches.

Different gill nets and fish traps used by the coastal fleet are anticipated to have a higher risk for entanglement of marine mammals. These assumptions and the practical problems associated with independent observers onboard small vessels were considered when we developed systems to initiate the monitoring of marine mammal by-catches in coastal waters. In 2006, 18 coastal gill-netters less that 15 meters total length were contracted by IMR, two vessels in each of nine domestic fishery statistics areas, to report detailed statistics on effort, catch and by-catches.

In total 194 marine mammals (149 harbour porpoises, 27 harbour seals 10 grey seal and 8 harp seals) were observed incidentally by-caught in 2006. The by-catches per ICES fishery statistics area, and cause of death are gives in Table 3. below, which also shows the reported directed take (by seal hunters) of the same species (commercial harvest is reported elsewhere).

6. ADVICE GIVEN AND MANAGEMENT MEASURES TAKEN

Sealing Advice on the management of harp and hooded seals is based on deliberations in the ICES/NAFO Working Group on Harp and Hooded Seals (WGHARP). WGHARP met at the Department of Fisheries and Oceans (DFO), St.Johns, Newfoundland, Canada, 30 August-3 September 2005, and in the ICES Headquarters, Copenhagen, Denmark, on 12-16 June 2006, to assess the stocks of Greenland Sea harp seals, White Sea / Barents Sea harp seals and Greenland Sea hooded seals. Updated information was available for all stocks to enable WGHARP to perform modelling which provided ICES with sufficient information to give advice (for harp seals in October 2005, for hooded seals in August 2006) on status and to identify catch options that would sustain the populations at present levels within a 10 year period.The management agencies requested advice on “sustainable” yields for these stocks. “Sustainable catch” as used in these yield estimates for seals means the catch that is risk neutral with regard to maintaining the population at its current size within the next 10 years.

Population assessments were based on a population model that estimates the current total population size. These estimates are then projected into the future to provide a future population size for which statistical uncertainty is provided for each set of catch options. The population model estimates the current total population size using historical catch data and estimates of pup production. In principle, the model can also estimate biological parameters (mortality and natality), but for the populations to 363

Norway – Progress Report Marine Mammals which the model is applied there is not enough data to provide accurate estimates of these parameters. To compensate for the lack of data, information from other similar populations are used as input to the model in the form of a prior distribution (mean and standard deviation) for each of the parameter. The same population dynamic model was used for both of the northeast Atlantic harp seal populations, but with stock specific values of prior distributions for mortality and natality. The modifications implemented in the model was an improvement from previously used estimation programs. In harp seals the modified model gives higher stock estimates and catch options than the previous model. These differences are primarily due to the change in the estimate of adult mortality (which was fixed at a value which is now regarded to have been to high) and the inclusion of additional sources of uncertainty in the parameters.

Based on the assessments performed by WGHARP, the ICES Advisory Committee on Fishery Managament (ACFM) provided advice on quotas for the 2006 season and following years. The recommended sustainable Total Allowable Catches (TACs) were set as follows: Harp seals in the East Ice 78,200 1+ equivalents, harp seals in the West Ice 31,200 1+ equivalents. If pups are to be taken, 2.5 and 2 are equivalent to 1 one year old or older seal for the two stocks respectively. Hooded seals were regarded more data-poor than the two harp seal populations and required a more risk adverse management approach. Results from a Norwegian aerial survey in 2005 suggested that current pup production (15,200) was lower than observed in a comparable 1997 survey (24,000). Model explorations indicated a decrease in population abundance from the late 1940s and up to the early 1980s. In the most recent two decades, the stock appeared to have stabilized at a low level of approximately 71,000. This may be only 10-15% of the level observed 60 years ago. Due to restricted availability of data, ICES has recommended an approach based on Potential Biological Removal level (PBR) in the assessment of this stock. The PBR approach identifies the maximum allowable removals that will ensure that the risk of the population falling below a certain lower limit is only 5% and that would allow a stock that dropped below this limit to recover. Using the PBR approach, the catch limit was calculated as 2,189 animals. However, ICES concludeed that even harvesting at the PBR level could result in a continued stock decline or a lack of recovery, and recommended that harvesting should not be permitted with the exception of catches for scientific purposes from 2007 on.

Traditionally, both Russia and Norway have participated in the sealing operations in the West Ice and the East Ice and have, therefore, allocated quotas on a bilateral basis in negotiations in the Joint Norwegian-Russian Fisheries Commission. However, the Russians cancelled their sealing operations in the West Ice in 2001. The Norwegian shares of the 2007 and 2008 quotas would be 31,200 harp seals (1+) in the West Ice (the total quotas in this area). In the East Ice, the Norwegian quota was set at 15,000 harp seals (1+). Russian aerial surveys of White Sea harp seal pups in 2004-2007 have, however, given indications of a possible reduction in pup production as compared with the results obtained in similar surveys in 1998-2003. These possible reductions is a matter of concern and the Commission agreed that the 2008 Barents Sea / White Sea quota should be preliminary reduced to 55 000 1+ animal where each 364

NAMMCO Annual Report 2007 - 2008

1+ seal could be balanced by 2.5 pups. The Norwegian share of this TAC should be 10 000 1+ animals. There is a general ban on catching females in the breeding lairs in the West Ice. The Norwegian ban on catching pups of the year, introduced in 1989, was lifted from the 1996 season onwards, and weaned pups can now be taken.

In 1996 new regulations for the “sustainable” hunt of coastal seals as well as compulsory catch reports were introduced. Quotas have been set based on the available information on abundance and allocated along the coast according to abundance within counties (common seals) or regions (grey seals). From the 2003 season, quotas were increased substantially by the Norwegian Ministry of Fisheries in comparison with previous years when set quotas generally followed recommendations based on scientific advice. The 2003 quotas were set at 1186 grey seals (25% of current abundance estimate) and 949 harbour seals (13% of current abundance estimate). The 2006 and 2007 quotas was kept at exactly the same levels as in 2003 for grey seals, whereas the harbour seal quota was reduced to 750 animals (following the availability of an updated abundance estimate) in 2006 and increased to 860 in 2007. Catches of grey seals were 329 and 456 in 2006 and 2007, respectively. The harbour seal hunt resulted in 660 (2006) and 905 (207) seals shot.

Whaling At the IWC Annual Meeting in 1992 Norway stated that it intended to reopen the traditional minke whaling in 1993. So far, IWC has accepted the RMP developed by its Scientific Committee as a basis for future management decisions but has not implemented the procedure. The Norwegian Government therefore decided to set quotas for the 1993 and following seasons based on RMP, with parameters tuned to the cautious approach level as expressed by the Commission and using the best current abundance estimates as judged by the IWC Scientific Committee. In later years research has been conducted on retuning of the procedure to other target levels than the original 0.72, chosen by the Commission. 2006 The total quota for the northeast Atlantic and the Jan Mayen area in 2006 was set to 1052 minke whales (Table IV.2) with 609 whales in the Northeastern management areas and 443 whales in the Jan Mayen area. The catch quotas are calculated for each of five management areas, and allocated on a per vessel basis with some over- regulation, which means that there also is some competition between vessels for the total quota. The basic catching season was from 1 April to 31 August. RMP essentially sets a five-year block quota where animals not taken in a particular year may be transferred to later years within the block. At the annual meeting of the IWC/SC in 2003 a new abundance estimate (80 500 minke whales for the Northeastern stock area and 26 700 minkes for the Jan Mayen block) based on the data collected in the period 1996-2001 was approved. These estimates were used in new RMP calculations that resulted in a total basic quota of 670 minke whales for 2004 and each of the following four years. The Small Area allocation of this total quota is: EB 170, EW 153, ES 113, EN 89 and CM 145. Including catches not taken in 2004, the total quota for 2005 was 796 minke whales. For 2006 the total catch quota was set

365

Norway – Progress Report Marine Mammals to 1,052 minke whales with 609 whales in the Northeastern area and 443 in the Jan Mayen (CM) area.

2007 For 2007 the total catch quota was set to 1,052 animals of which 900 may be taken within the Northeastern stock area (the E Small Areas) and 152 within the CM area of the Central minke whale stock. The catch quotas are calculated for each of five management areas, but for practical purposes no allocation was made on the different E areas at the start of the 2007 catching season. However, accounts of the catch were kept and in late May a restriction of a maximum catch of 165 minke whales was introduced for the EW area to avoid the Small Area quota to be exceeded. The catching in EW was stopped on 25 June 2007.

For 2008 a total quota of 1052 minke whales has been set, of which 900 may be taken within the North-eastern stock area (i.e. the EW, EN, ES and EB Small Areas) and 152 in the Jan Mayen area (Small Area CM). There is also a further restriction that not more than 155 minke whales can be taken in the EW Small Area.
