WELCOME AND MEETING INFORMATION 1.1 Introduction Jill Prewitt, Scientific Secretary of NAMMCO, welcomed the participants (Appendix 1) to Hillerød and expressed the satisfaction of NAMMCO that this long-awaited review was taking place. She conveyed the deep regrets of the chair of the Planning Group, Arne Bjørge (IMR, Norway), who was not able to attend the meeting due to health issues, and thanked Rod Hobbs, the vice-chair, for agreeing to step in. She briefly introduced NAMMCO, summarized background for the Global Review, and acknowledged Christina Lockyer, the former NAMMCO General Secretary, for her efforts to launch this Global Review. She also thanked the other members of the Planning Group (Barry, Bjørge, Desportes, Ferguson, Guldborg-Hansen, Hobbs, Marcoux, Reeves, Shpak, Suydam) and noted that the Arctic Council’s Conservation of Arctic Flora and Fauna (CAFF) biodiversity working group had joined the effort to organise the review. Although Tom Barry (CAFF Secretariat) was unable to participate, his colleague Tom Christensen, co-chair of CAFFs Circumpolar Biodiversity Monitoring Program (CBMP), attended. She also thanked the funders who made the Global Review possible, primarily NAMMCO, the Government of Greenland, Shell Oil and the US Marine Mammal Commission. 1.2 Chair’s welcome Hobbs, the meeting Chair, welcomed the participants and noted that the International Whaling Commission’s (IWC’s) Scientific Committee had reviewed the status of belugas and narwhals in 1992 (IWC 1993) and conducted a more thorough updated review of beluga stocks in 1999 (IWC 2000). Additionally, the NAMMCO Scientific Committee’s Working Group on the Population Status of Beluga and Narwhal in the North Atlantic carried out an extensive review in 1999 (NAMMCO 2000).

  • Thermal State of Permafrost in North $PHULFD
    Thermal State of Permafrost in North America: A Contribution to the International Polar Year ABSTRACT A snapshot of the thermal state of permafrost in northern North America during the International Polar Year (IPY) was developed using ground temperature data collected from 350 boreholes. More than half these were established during IPY to enhance the network in sparsely monitored regions. The measurement sites span a diverse range of ecoclimatic and geological conditions across the continent and are at various elevations within the Cordillera. The ground temperatures within the discontinuous permafrost zone are generally above -3°C, and range down to -l5oC in the continuous zone. Ground temperature envelopes vary according to substrate, with shallow depths of zero annual amplitude for peat and mineral soils. and much greater depths for bedrock. New monitoring sites in the mountains of southern and central Yukon suggest that permafrost may be limited in extent. In concert with regional air temperatures, permafrost has generally been warming across North America for the past several decades, as indicated by measurements from the western Arctic since the 1970s and from parts of eastern Canada since the early 1990s. The rates of ground warming have been variable, but are generally greater north of the treeline. Latent heat effects in the southern discontinuous zone dominate the permafrost thermal regime close to 0oC and allow permafrost to persist under a warming climate. Consequently, the spatial diversity of permafrostthermal conditions is decreasing over time. Copyright @ 2010 Crown in the right of Canada and John Wiley & Sons, Ltd. KEY WORDS: permafrost; ground temperature regime: climate change; permafrost thaw; active layer: International Polar Year; North America INTRODUCTION About 30% of the permafrost in the Northern Hemisphere is in North America.

  • Transits of the Northwest Passage to End of the 2020 Navigation Season Atlantic Ocean ↔ Arctic Ocean ↔ Pacific Ocean
    TRANSITS OF THE NORTHWEST PASSAGE TO END OF THE 2020 NAVIGATION SEASON ATLANTIC OCEAN ↔ ARCTIC OCEAN ↔ PACIFIC OCEAN R. K. Headland and colleagues 7 April 2021 Scott Polar Research Institute, University of Cambridge, Lensfield Road, Cambridge, United Kingdom, CB2 1ER. <[email protected]> The earliest traverse of the Northwest Passage was completed in 1853 starting in the Pacific Ocean to reach the Atlantic Oceam, but used sledges over the sea ice of the central part of Parry Channel. Subsequently the following 319 complete maritime transits of the Northwest Passage have been made to the end of the 2020 navigation season, before winter began and the passage froze. These transits proceed to or from the Atlantic Ocean (Labrador Sea) in or out of the eastern approaches to the Canadian Arctic archipelago (Lancaster Sound or Foxe Basin) then the western approaches (McClure Strait or Amundsen Gulf), across the Beaufort Sea and Chukchi Sea of the Arctic Ocean, through the Bering Strait, from or to the Bering Sea of the Pacific Ocean. The Arctic Circle is crossed near the beginning and the end of all transits except those to or from the central or northern coast of west Greenland. The routes and directions are indicated. Details of submarine transits are not included because only two have been reported (1960 USS Sea Dragon, Capt. George Peabody Steele, westbound on route 1 and 1962 USS Skate, Capt. Joseph Lawrence Skoog, eastbound on route 1). Seven routes have been used for transits of the Northwest Passage with some minor variations (for example through Pond Inlet and Navy Board Inlet) and two composite courses in summers when ice was minimal (marked ‘cp’).

  • Canadian Arctic Tide Measurement Techniques and Results
    International Hydrographie Review, Monaco, LXIII (2), July 1986 CANADIAN ARCTIC TIDE MEASUREMENT TECHNIQUES AND RESULTS by B.J. TAIT, S.T. GRANT, D. St.-JACQUES and F. STEPHENSON (*) ABSTRACT About 10 years ago the Canadian Hydrographic Service recognized the need for a planned approach to completing tide and current surveys of the Canadian Arctic Archipelago in order to meet the requirements of marine shipping and construction industries as well as the needs of environmental studies related to resource development. Therefore, a program of tidal surveys was begun which has resulted in a data base of tidal records covering most of the Archipelago. In this paper the problems faced by tidal surveyors and others working in the harsh Arctic environment are described and the variety of equipment and techniques developed for short, medium and long-term deployments are reported. The tidal characteris­ tics throughout the Archipelago, determined primarily from these surveys, are briefly summarized. It was also recognized that there would be a need for real time tidal data by engineers, surveyors and mariners. Since the existing permanent tide gauges in the Arctic do not have this capability, a project was started in the early 1980’s to develop and construct a new permanent gauging system. The first of these gauges was constructed during the summer of 1985 and is described. INTRODUCTION The Canadian Arctic Archipelago shown in Figure 1 is a large group of islands north of the mainland of Canada bounded on the west by the Beaufort Sea, on the north by the Arctic Ocean and on the east by Davis Strait, Baffin Bay and Greenland and split through the middle by Parry Channel which constitutes most of the famous North West Passage.
