Transits of the Northwest Passage to End of the 2019 Navigation Season Atlantic Ocean ↔ Arctic Ocean ↔ Pacific Ocean
TRANSITS OF THE NORTHWEST PASSAGE TO END OF THE 2019 NAVIGATION SEASON ATLANTIC OCEAN ↔ ARCTIC OCEAN ↔ PACIFIC OCEAN R. K. Headland and colleagues 12 December 2019 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 but used sledges over the sea ice of the central part of Parry Channel. Subsequently the following 314 complete maritime transits of the Northwest Passage have been made to the end of the 2019 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 (transits 149 and 167). -

Who Discovered the Northwest Passage? Janice Cavell1
ARCTIC VOL. 71, NO.3 (SEPTEMBER 2018) P.292 – 308 https://doi.org/10.14430/arctic4733 Who Discovered the Northwest Passage? Janice Cavell1 (Received 31 January 2018; accepted in revised form 1 May 2018) ABSTRACT. In 1855 a parliamentary committee concluded that Robert McClure deserved to be rewarded as the discoverer of a Northwest Passage. Since then, various writers have put forward rival claims on behalf of Sir John Franklin, John Rae, and Roald Amundsen. This article examines the process of 19th-century European exploration in the Arctic Archipelago, the definition of discovering a passage that prevailed at the time, and the arguments for and against the various contenders. It concludes that while no one explorer was “the” discoverer, McClure’s achievement deserves reconsideration. Key words: Northwest Passage; John Franklin; Robert McClure; John Rae; Roald Amundsen RÉSUMÉ. En 1855, un comité parlementaire a conclu que Robert McClure méritait de recevoir le titre de découvreur d’un passage du Nord-Ouest. Depuis lors, diverses personnes ont avancé des prétentions rivales à l’endroit de Sir John Franklin, de John Rae et de Roald Amundsen. Cet article se penche sur l’exploration européenne de l’archipel Arctique au XIXe siècle, sur la définition de la découverte d’un passage en vigueur à l’époque, de même que sur les arguments pour et contre les divers prétendants au titre. Nous concluons en affirmant que même si aucun des explorateurs n’a été « le » découvreur, les réalisations de Robert McClure méritent d’être considérées de nouveau. Mots clés : passage du Nord-Ouest; John Franklin; Robert McClure; John Rae; Roald Amundsen Traduit pour la revue Arctic par Nicole Giguère. -
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. -

Unfrozen Sea: Sailing the Northwest Passage
UNFROZEN SEA: SAILING THE NORTHWEST PASSAGE Michael Byers In late October 2006, Michael Byers travelled through Bellot Strait in the Canadian North, on the the first ship ever to do so in October. “We were 700 kilometres north of the Artic Circle“ he writes, “but there was no ice.” The shrinking sea of Canada’s Arctic region poses challenges both for the ecosystem and for animals such as the polar bear, as well as for Canada’s claims of Arctic sovereignty over disputed waters such as the Northwest Passage. Where explorers once died in search of the “Arctic Grail,” a northern route from Europe to Asia, the Northwest Passage is now open water in the summer. “In March 2006,” writes Byers, “the area covered during the winter by sea-ice was at an all-time low: 300,000 square kilometres less than the previous year. At this rate the Arctic could lose all its sea-ice by 2030.” Fin octobre 2006, Michael Byers s’est rendu dans le Nord canadien par le détroit de Bellot, à bord du premier bateau à faire cette traversée en octobre. « Nous étions à 700 kilomètres au nord du cercle arctique et il n’y avait pas de glace », écrit-il. Le retrait de la mer dans la région arctique du Canada constitue un défi pour l’écosystème et les populations animales, notamment les ours polaires, mais aussi pour la souveraineté revendiquée par notre pays sur des eaux contestées comme celles du passage du Nord- Ouest. Là où sont morts des explorateurs en quête du « Graal arctique » — une route du Nord entre l’Europe et l’Asie —, ce passage est devenu en été une étendue d’eau libre. -
