Arctic Coastal Dynarnics Edited by Volker Rachold, Hugues Lantuit, Nicole Couture and Wayne Pollard Arctic Coastal Dynarnics Report of the 5" International Workshop McGill University, Montreal (Canada), 13-16 October 2004 Edited by Volker Rachold, Hugues Lantuit, Nicole Couture and Wayne Pollard Ber. Polarforsch. Meeresforsch. 506 (2005) ISSN 1618 - 3193 Volker Rachold, Alfred Wegener Institute, Research Unit Potsdam, Telegrafenberg A43, 14473 Potsdam, Germany Hugues Lantuit, McGill University, Department of Geography, 805 Sherbrooke Street West, Montreal, Quebec, Canada H3A 2K6 present address: Alfred Wegener Institute, Research Unit Potsdam, Telegrafenberg A43, 14473 Potsdam, Germany Nicole Couture, McGill University, Department of Geography, 805 Sherbrooke Street West, Montreal, Quebec, Canada H3A 2K6 Wayne Pollard, McGill University, Department of Geography, 805 Sherbrooke Street West, Montreal, Quebec, Canada H3A 2K6 Pre face Arctic Coastal Dynamics (ACD) is ajoint project of the International Arctic Science Committee (IASC) and the International Perrnafiost Association (IPA) and it is a regional project of the International Geosphere-Biosphere Program Land- Ocean Interactions in the Coastal Zone (IGBP-LOICZ). Its overall objective is to improve our understanding of circum- Arctic coastal dynamics as a function of environmental forcing, coastal geology and cryology and morphodynamic behavior. The fifth IASC-sponsored ACD workshop was held in Montreal, Canada, on October 13-16, 2004. Participants from Canada (20), Gerrnany (3), Malaysia (I), the Netherlands (1), Norway (I), Russia (14), and the United States (6) attended. The objective of the workshop was to review the Status of ACD according to the Science and Implementation Plan, with the main focus On completing the circum-Arctic ACD segmentation and classification and initiating the development of web-deliverable GIS products. During the first Part of the workshop, Progress reports of the working groups of the last workshop held in St. Petersburg (Russia) in November 2003 were presented, as were 44 scientific Papers dealing with regional andlor circum-Arctic coastal dynamics. In addition to the established ACD working groups On (1) GIS Development, (2) Transition fiom Onshore to Offshore Perrnafrost and (3) Environmental Forcing, a new theme introduced at the Canadian workshop was (4) the Human Dimensions of Arctic Coastal Dynarnics. Finally, the results of the workshop and the next steps to be taken were discussed in the ACD Steering Committee meeting. The present report summarizes the program of the workshop and the main results. Financial support from the International Arctic Sciences Committee (IASC) is highly appreciated and was essential for conducting the workshop. The Canadian Department of Foreign Affairs and International Trade (DFAIT) and the Canadian International Development Agency (CIDA) provided support for six Russian participants.

  • Birds of Mansel Island, Northern Hudson Bay Anthony J
    The Canadian Field-Naturalist Birds of Mansel Island, northern Hudson Bay Anthony J. Gaston Science and Technology Branch, Environment and Climate Change Canada, Carleton University, Ottawa, Ontario K1A 0H3 Canada; email: [email protected] Gaston, A.J. 2019. Birds of Mansel Island, northern Hudson Bay. Canadian Field-Naturalist 133(1): 20–24. https://doi.org/ 10.22621/cfn.v133i1.2153 Abstract A recent review of bird distributions in Nunavut demonstrated that Mansel Island, in northeastern Hudson Bay, is one of the least known areas in the territory. Here, current information on the birds of Mansel Island is summarized. A list published in 1932 included 24 species. Subsequent visits by ornithologists since 1980 have added a further 17 species to the island’s avifauna. The list includes 17 species for which breeding has been confirmed and 10 for which breeding is considered prob- able. The island seems to support particularly large populations of King Eiders (Somateria spectabilis) and Tundra Swans (Cygnus columbianus) and the most southerly breeding population of Sabine’s Gull (Xema sabini) and Red Knot (Calidiris canuta; probably). Key words: Mansel Island; Hudson Bay; birds; breeding Introduction leaved Mountain Avens (Dryas integrifolia Vahl) and At 3180 km2, Mansel Island, Qikiqtaaluk Region, Purple Mountain Saxifrage (Saxifraga op po sitifolia Nunavut, is the 28th largest island in Canada.

    DEPARTMENT OF THE INTERIOR Fish and Wildlife Service 50 CFR Part 17 [FWS-R7-ES-2009-0024] [MO9221050083-B2] Endangered and Threatened Wildlife and Plants; 12-Month Finding on a Petition to List the Yellow-Billed Loon as Threatened or Endangered AGENCY: Fish and Wildlife Service, Interior. ACTION: Notice of 12-month petition finding. SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the yellow-billed loon (Gavia adamsii) as threatened or endangered, with critical habitat, under the Endangered Species Act of 1973, as amended 1 (Act). The petitioners provided two listing options for consideration by the Service: (1) listing the yellow-billed loon throughout its range, or (2) listing the United States population of the yellow-billed loon as a Distinct Population Segment (DPS). After a review of the best available scientific and commercial information, we have determined that listing the yellow-billed loon rangewide under the Act is warranted but precluded by other higher priority listing actions. DATES: This finding was made on [INSERT DATE OF PUBLICATION IN THE FEDERAL REGISTER]. ADDRESSES: This finding is available on the Internet at http://www.regulations.gov. Data, information, comments, or questions regarding this notice should be submitted to the Field Supervisor, Endangered Species Branch, Fairbanks Fish and Wildlife Field Office, U.S. Fish and Wildlife Service, 101-12th Ave., Room 110, Fairbanks, AK 99701. The complete administrative file for this finding is available for public inspection, by appointment, during normal business hours at the above address. FOR FURTHER INFORMATION CONTACT: Mr.

The SC had the T-NASS Steering Committee- Proposal for T-NASS2015 and report from the NASS2015 Joint Technical, Planning and Steering meeting (Annex 1), and a summary of the NAMMCO-Joint Commission on Narwhal & Beluga (JCNB) Catch Allocation Sub-group Meeting (SC/21/07). National Progress Reports (NPRs) were received from all member countries and observers except for the Greenlandic NPR, which was not received in time for consideration at the meeting. Other reports and documents were presented and were examined under the relevant agenda items. COOPERATION WITH OTHER ORGANISATIONS ASCOBANS plans to write to the EU regarding the Faroese pilot whale hunt. The SC and Secretariat did not know if this letter had been written at the time of the SC meeting. These issues are usually handled by the Ministry of Foreign Affairs. Formally NAMMCO and ASCOBANS have an official agreement on exchange of observers. The SC recommended that the NAMMCO Secretariat request harbour porpoise by-catch numbers for the North Sea from ASCOBANS, when needed for future assessments/WGs. A request for NAMMCO to join the ICES WGHARP was sent from the NAMMCO Secretariat to the ICES Secretariat in August 2014. Role of Marine Mammals in the Ecosystem The traditional perception of prey species preference of killer whales in the Northeast Atlantic has, to a large extent, been linked to herring.
