A two-box model was used to identify and assess physical, biological, and chemical processes responsible for the seasonal variability of DIC, DOC, TA, and pCO2. Surface waters were undersaturated with respect to atmospheric CO2 throughout the year and constituted a net sink of 22 21 1.2 mol C m yr , with ice coverage and ice formation limiting the CO2 uptake during winter.

    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’).

    ARCTIC VOL. 55, SUPP. 1 (2002) P. 4–17 Canadian Beaufort Sea 2000: The Environmental and Social Setting G. BURTON AYLES1 and NORMAN B. SNOW2 (Received 1 March 2001; accepted in revised form 2 January 2002) ABSTRACT. The Beaufort Sea Conference 2000 brought together a diverse group of scientists and residents of the Canadian Beaufort Sea region to review the current state of the region’s renewable resources and to discuss the future management of those resources. In this paper, we briefly describe the physical environment, the social context, and the resource management processes of the Canadian Beaufort Sea region. The Canadian Beaufort Sea land area extends from the Alaska-Canada border east to Amundsen Gulf and includes the northwest of Victoria Island and Banks Island. The area is defined by its geology, landforms, sources of freshwater, ice and snow cover, and climate. The social context of the Canadian Beaufort Sea region has been set by prehistoric Inuit and Gwich’in, European influence, more recent land-claim agreements, and current management regimes for the renewable resources of the Beaufort Sea. Key words: Beaufort Sea, Inuvialuit, geography, environment, ethnography, communities RÉSUMÉ. La Conférence de l’an 2000 sur la mer de Beaufort a attiré un groupe hétérogène de scientifiques et de résidents de la région de la mer de Beaufort en vue d’examiner le statut actuel des ressources renouvelables de cette zone et de discuter de leur gestion future. Dans cet article, on décrit brièvement l’environnement physique, le contexte social et les processus de gestion des ressources de la zone canadienne de la mer de Beaufort.
