GENERAL UNEP/CBD/SBSTTA/16/INF/5 21 April 2012** ENGLISH ONLY SUBSIDIARY BODY ON SCIENTIFIC, TECHNICAL AND TECHNOLOGICAL ADVICE Sixteenth meeting Montreal, 30 April-5 May 2012 Item 6.1 of the provisional agenda* REPORT OF JOINT OSPAR/NEAFC/CBD SCIENTIFIC WORKSHOP ON EBSAs Information note by the Executive Secretary 1. In paragraph 36 of its decision X/29, the Conference of the Parties requested the Executive Secretary to work with Parties and other Governments as well as competent organizations and regional initiatives, such as the Food and Agriculture Organization of the United Nations (FAO), regional seas conventions and action plans, and, where appropriate, regional fisheries management organizations (RFMOs), with regards to fisheries management, to organize a series of regional workshops, including the setting of terms of references, before a future meeting of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) prior to the eleventh meeting of the Conference of the Parties to the Convention, with a primary objective to facilitate the description of ecologically or biologically significant marine areas (EBSAs) through application of scientific criteria in annex I of decision IX/20 as well as other relevant compatible and complementary nationally and intergovernmentally agreed scientific criteria, as well as the scientific guidance on the identification of marine areas beyond national jurisdiction, which meet the scientific criteria in annex I to decision IX/20. 2. Pursuant to this request, a Joint Scientific Workshop was convened by the OSPAR Commission and the North-East Atlantic Fisheries Commission (NEAFC) in collaboration with the Secretariat of the Convention on Biological Diversity to describe areas meeting scientific criteria for EBSAs and other relevant criteria, in Hyères, France, from 8 to 9 September 2011. 3. The workshop report is circulated, together with the cover letter signed by the executive secretaries of OSPAR Commission and NEAFC, in the form and language in which it was received by the Secretariat of the Convention on Biological Diversity. ** Reposted to include the following footnote: “The designations employed and the presentation of material in this note do not imply the expression of any opinion whatsoever on the part of the Secretariat concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries.” * UNEP/CBD/SBSTTA/16/1. /… In order to minimize the environmental impacts of the Secretariat’s processes, and to contribute to the Secretary-General’s initiative for a C-Neutral UN, this document is printed in limited numbers.

Dr Braulio Ferreira de Souza Dias Executive Secretary Convention on Biological Diversity United Nations Environment Programme 413 Saint Jacques Street Suite 800 – World Trade Center Montreal, Qc, H2Y 1N9 CANADA 15 February 2012 Dear Dr Dias North-East Atlantic Regional EBSA Workshop outcomes On behalf of the Regional Seas Convention (OSPAR) and Regional Fisheries Management Organisation (NEAFC) for the North-East Atlantic we would like to congratulate you on your appointment as Executive Secretary for the Convention on Biological Diversity. Further to our letter dated 14 December 2011, we have the honour to provide a description of candidate EBSAs in the North-East Atlantic region, representing a summary of the results of the North-East Atlantic Regional EBSA Workshop held in Hyeres, France, in September 2011 (the full report of which has already been forwarded to CBD Secretariat). We understand from colleagues at the CBD Secretariat that the full Workshop report will be presented as an Information Document to SBSTTA 16, and that this summary document should serve to provide information in a more manageable format. Regarding our submissions we would like to emphasise that: a. The North-East Atlantic Workshop report, together with this summary, are the products of a purely scientific and technical exercise. Both OSPAR and NEAFC have made arrangements for further scrutiny and political evaluation of the Workshop outcomes. OSPAR and NEAFC have not finalised their work regarding the candidate EBSAs or made decisions on them. For this reason the results are set out as candidate EBSAs;1 b. Further scrutiny will include advice from the International Council for the Explorations of the Sea (ICES), the details of which will also be communicated to the CBD Secretariat; c. Although consideration was also given to dependency, representativeness, biogeographical importance, structural complexity, natural beauty and geological history, the North-East Atlantic Regional Workshop did not consider the criteria of ‘naturalness’ but subsequent evaluation will do so; and d. The OSPAR Commission, at its meeting of Contracting Parties in June 2011, agreed that the six High Seas Marine Protected Areas, designated by Ministers in 2010 and representing the world’s first network of MPAs in Area Beyond National Jurisdiction, should automatically qualify as EBSAs and 1 The terminology adopted for the workshop was to bring forward proposals for consideration and, once agreed, to establish candidate EBSAs. instructed the OSPAR Secretariat to submit these areas to the CBD EBSA Repository as an independent exercise. We consider this Workshop to have been an excellent example of the cooperation between our two Regional Conventions, and we very much appreciated the support and input of the CBD Secretariat to facilitate this event. We look forward to a continuing fruitful cooperation. Yours sincerely David Johnson Stefan Asmundsson Executive Secretary Executive Secretary OSPAR Commission NEAFC Enc Joint OSPAR/NEAFC/CBD Scientific Workshop on the Identification of Ecologically or Biologically Significant Marine Areas (EBSAs) in the North-East Atlantic Hyères, France: 8 – 9 September 2011 Joint OSPAR/NEAFC/CBD Scientific Workshop on the identification of Ecologically or Biologically Significant Marine Areas (EBSAs) in the North-East Atlantic Background and aims of the workshop 1. The 10th Conference of the Parties to the Convention on Biological Diversity (CBD COP 10; Nagoya, Japan, 18-29 October 2010) in its Decision on Marine and Coastal Biological Diversity (CBD Decision X/29, http://www.cbd.int/decision/cop/?id=12295) Annex 1 sets out the process on the identification of Ecologically or Biologically Significant Marine Areas (EBSAs) based upon the scientific criteria as previously adopted by CBD COP 9 (http://www.cbd.int/doc/decisions/cop-09/cop-09-dec-20-en.doc). 2. In particular, § 36 of CBD Decision X/29: “Requests the [CBD] Executive Secretary to work with Parties and other Governments as well as competent organizations and regional initiatives, such as the Food and Agriculture Organization of the United Nations (FAO), regional seas conventions and action plans, and, where appropriate, regional fisheries management organizations (RFMOs), with regards to fisheries management, to organize, including the setting of terms of references, subject to the availability of financial resources, a series of regional workshops, before a future meeting of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA) prior to the eleventh meeting of the Conference of the Parties to the Convention, with a primary objective to facilitate the description of ecologically or biologically significant marine areas through application of scientific criteria in annex I of decision IX/20 as well as other relevant compatible and complementary nationally and intergovernmentally agreed scientific criteria, as well as the scientific guidance on the identification of marine areas beyond national jurisdiction, which meet the scientific criteria in annex I to decision IX/20;”. 3. With a view to respond to the request set out in § 36 of CBD Decision X/29 and in light of the complementary competencies assigned to the OSPAR Commission and the North-East Atlantic Fisheries Commission (NEAFC), and as recognised in the Memorandum of Understanding between OSPAR and NEAFC, the two organisations together with the CBD Secretariat undertook to facilitate the identification and description of EBSAs in the North-East Atlantic through a joint scientific workshop prior to the eleventh meeting of the Conference of the Parties to the CBD. 4. The objective of this scientific workshop was to identify and describe marine areas in the high seas areas in the North-East Atlantic not included in the OSPAR Network of MPAs or the NEAFC Closed Areas but which fulfilled the scientific criteria set out by the CBD (Annex I of CBD Decision IX/20) for Ecologically or Biologically Significant Marine Areas (EBSAs) - with a view to respond to the request by CBD COP 10 (CBD Decision X/29, § 36). Agreed terms of reference are at Annex 2. 5. The geographic area of focus for the workshop was confined to the OSPAR Maritime Area and the Regulatory Area of NEAFC in areas beyond the EEZ of Contracting Parties (i.e. beyond 200 nautical miles). 1 of 13 OSPAR/NEAFC/CBD NEA EBSA Workshop 2011 6. At its 2011 Commission meeting, OSPAR agreed to report to the CBD Secretariat the six existing OSPAR Marine Protected Areas in areas beyond national jurisdiction that fulfil CBD EBSA criteria for inclusion in the CBD EBSA repository. These were therefore, not a primary consideration at the workshop. NEAFC is in the process of giving further consideration

  • The Climate-Sensitive Vesterisbanken Area (Central Greenland Sea): Depositional Environment and Paleoceanography During the Past 250,000 Years
    The climate-sensitive Vesterisbanken area (central Greenland Sea): Depositional environment and paleoceanography during the past 250,000 years MARTIN ANTONOW1, PETER MARTIN GOLDSCHMIDT2j3and HELMUT ERLENKEUSER2 1. Freiberg University of Mining and Technology, Institute of Geology, Bernhard-von-Cotta-Str. 2, D-09596 Freiberg, Germany 2. SFB 313, University of Kiel, Heinrich-Hecht-Platz 10, D-24118 Kiel, Germany 3. present address: PCD, Eckernforder Str. 259, D-24119 Kiel, Germany ABSTRACT Sedimentological, micropaleontological and geochemical studies of sediment cores from the Vesterisbanken region were used to reconstruct the sedimentation pattern, depositional history and paleoceanography for this area over the last 250,000 years. The dating and correlation of the sediments were based on oxygen isotope stratigraphy and absolute ages. The hemipelagic deposits near the Vesteris Seamount are characterised by biogenic, ter- restrial and volcanogenic sediment input that varies through time. The area was influenced by sporadic turbidity currents and thermohaline-induced contour currents. Ice-rafted debris occurred nearly throughout the investigated time interval. Primary production was higher during interglacial periods. Filter-feeding epifauna (C. zi~~~t~llt~rst~rji),an indicator of bottom cur- rents, dominated in isotope stages 7 and 5. During deglaciation (stage boundaries 8/7, 6/5 and 2/1, events 3.3 and 3.1), enorinous meltwater inp~~tstabilised the water column, leading to periodic interruptions in deep water renewal. The influence of water masses from the Polar and Atlantic Domains in the Greenland Sea were very variable over time. The oceanic fronts in the Vesterisbanken area were always close together, allowing only a narrow Arctic Domain to exist.

  • Seamounts and Oceanic Igneous Features in the NE Atlantic: a Link Between Plate Motions and Mantle Dynamics

Seamounts on oceanic crust dated 54–50 Ma are formed on smooth oceanic basement, which resulted from high spreading rates and magmatic productivity enhanced by higher than usual mantle plume activ- ity. Late Eocene–Early Miocene SOIF clusters are located close to newly formed tectonic features on rough oceanic crust in the Irminger, Iceland and Norway basins, reflecting an unstable tectonic regime prone to local readjustments of mid-ocean ridge and fracture zone segments accompanied by extra igneous activity. A SOIF population observed on Mid-Miocene–Present rough oceanic basement in the Greenland and Lofoten basins, and on conjugate Kolbeinsey Ridge flanks, coin- cides with an increase in spreading rate and magmatic productivity. We suggest that both tec- tonic/kinematic and magmatic triggers produced Mid-Miocene–Present SOIFs, but the Early Miocene westwards ridge relocation may have played a role in delaying SOIF formation south of the Jan Mayen Fracture Zone.

MERIAN cruise MSM86 Vesteris Seamount was aimed at improving our understanding of the evolution of Vesteris Seamount, a large and lone intraplate volcano in the Greenland Sea. We had also planned to sample other basement highs in the region to determine their age and origin. Mapping and sampling several basement outcrops in the Greenland Basin, specifically Vesteris Seamount, Logi Ridge and Southern Seamount, as well as suspected volcanic edifices northeast of Vesteris Seamount were the main activites planned. We used the remotely operated vehicle MARUM SQUID 2000 and the TV-guided grab from GEOMAR for sampling rocks and biota. CTD casts were conducted to collect deep-sea water samples and sound velocity profiles for bathymetric mapping. The ship’s EM122 and 712 echosounders were be used by bathymetry and backscatter surveys as well as for the collection of water column data, aimed at locating flares of CO2 bubbles released from Vesteris seamount, which is a dormant volcano. Our research objectives include (1) resolving mantle melting dynamics and source composition and their bearing for the geodynamic evolution of the northern North Atlantic, (2) reconstructing the volcanic growth of Vesteris Seamount and its partial destruction by slope failures, (3) investigating the diversity of sponges and the microbiomes they host at Vesteris Seamount and other basement highs, and (4) examining the colonization of volcanic rocks by microorganisms, including fungi and bacteria, and determining the relation between rock alteration and endolithic life.

Cover: © Bernd Christiansen / OASIS Preface Although there are tens of thousands of seamounts spread throughout the world's oceans, these undersea features are still little-known environments with regard to their biodiversity, their ecology and the short and long-term effects of human impacts. However, it has become clear in recent years that seamounts host very special ecosystems which are at risk from intensive exploitation of their natural resources. Most studies on seamounts have been conducted in the Pacific. Although some North East Atlantic seamounts were studied already in the 1970s, the knowledge base is very limited and information is scattered through various disciplines, and many scientific results are unpublished.
