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). -

Wolf-Sightings on the Canadian Arctic Islands FRANK L
ARCTIC VOL. 48, NO.4 (DECEMBER 1995) P. 313–323 Wolf-Sightings on the Canadian Arctic Islands FRANK L. MILLER1 and FRANCES D. REINTJES1 (Received 6 April 1994; accepted in revised form 13 March 1995) ABSTRACT. A wolf-sighting questionnaire was sent to 201 arctic field researchers from many disciplines to solicit information on observations of wolves (Canis lupus spp.) made by field parties on Canadian Arctic Islands. Useable responses were obtained for 24 of the 25 years between 1967 and 1991. Respondents reported 373 observations, involving 1203 wolf-sightings. Of these, 688 wolves in 234 observations were judged to be different individuals; the remaining 515 wolf-sightings in 139 observations were believed to be repeated observations of 167 of those 688 wolves. The reported wolf-sightings were obtained from 1953 field-weeks spent on 18 of 36 Arctic Islands reported on: no wolves were seen on the other 18 islands during an additional 186 field-weeks. Airborne observers made 24% of all wolf-sightings, 266 wolves in 48 packs and 28 single wolves. Respondents reported seeing 572 different wolves in 118 separate packs and 116 single wolves. Pack sizes averaged 4.8 ± 0.28 SE and ranged from 2 to 15 wolves. Sixty-three wolf pups were seen in 16 packs, with a mean of 3.9 ± 2.24 SD and a range of 1–10 pups per pack. Most (81%) of the different wolves were seen on the Queen Elizabeth Islands. Respondents annually averaged 10.9 observations of wolves ·100 field-weeks-1 and saw on average 32.2 wolves·100 field-weeks-1· yr -1 between 1967 and 1991. -

CANADA'S SOVEREIGNTY OVER THE NORTHWEST PASSAGE Donat Pharand* In 1968, when this writer published "Innocent Passage in the Arc- tic,"' Canada had yet to assert its sovereignty over the Northwest Pas- sage. It has since done so by establishing, in 1985, straight baselines around the whole of its Arctic Archipelago. In August of that year, the U. S. Coast Guard vessel PolarSea made a transit of the North- west Passage on its voyage from Thule, Greenland, to the Chukchi Sea (see Route 1 on Figure 1). Having been notified of the impending transit, Canada informed the United States that it considered all the waters of the Canadian Arctic Archipelago as historic internal waters and that a request for authorization to transit the Northwest Passage would be necessary. -
Hudson Bay Ice Conditions
Hudson Bay Ice Conditions ERIC W. DANIELSON, JR.l ABSTRACT.Monthly mean ice cover distributions for Hudson Bay have been derived, based upon an analysis of nine years of aerial reconnaissance and other data. Information is presented in map form, along with diseussian Of significant features. Ice break-up is seen to work southward from the western, northern, and eastern edges of the Bay; the pattern seems to be a result of local topography, cur- rents, and persistent winds. Final melting occurs in August. Freeze-up commences in October, along the northwestern shore, and proceeds southeastward. The entire Bay is ice-covered by early January,except for persistent shore leads. RÉSUMÉ. Conditions de la glace dans la mer d’Hudson. A partir de l’analyse de neuf années de reconnaissances aériennes et d’autres données, on a pu déduire des moyennes mensuelles de distribution de la glace pour la mer d’Hudson. L‘informa- tion est présentte sous formes de cartes et de discussion des Cléments significatifs. On y voit que la débâcle progresse vers le sud à partir des marges ouest, nord et est dela mer; cette séquence sembleêtre le résultat de la topographielocale, des courants et .des vents dominants. La fonte se termine en aofit. L’enge€wommence en octobre le long de la rive nord-ouest et progresse vers le sud-est. Sauf pow les chenaux côtiers persistants, la mer est entihrement gelée au début de janvier. INTRODUCTION In many respects, ice cover is a basic hydrometeorological variable. In Hudson Bay (Fig. 1) it might be considered the most basic of all, as it influences all other conditions so decisively. -
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. -
Markham Bay – Western Hudson Strait – Foxe Channel
Written Submission No. 41 2016 Draft Nunavut Land Use Plan Proposed Amendment and Enlargement of Key Migratory Bird Site # 33: Community Area of Interest – Multiple Values: Markham Bay – Western Hudson Strait – Foxe Channel To: The Nunavut Planning Commission From: The Qikiqtaaluk Wildlife Board (QWB), and the Hunters and Trappers Organization (HTO) of Kimmirut and Cape Dorset Background Information: Multiple resources that are highly valued by the Inuit of Kimmirut and Cape Dorset occur on the islands and in the waters of Markham Bay, western Hudson Strait and Foxe Channel off the coast of Baffin Island (i.e., a Multiple Value Area, MVA). The important waters extend to at least 20 km from Baffin Island and the outer-most associated islands. The Key Migratory Bird Site # 33 in the draft 2016 Nunavut Land Use Plan should be changed to a Community Area of Interest as a protected area and expanded to include these waters and islands. Without protection of this area, plus others near Kimmirut and Cape Dorset, the Nunavut Land Use Plan will fail in its goal to protect and promote the well-being of all of Nunavut’s residents and communities as a primary purpose of land use planning under Article 11 of the Nunavut Agreement. This enlarged Community Area of Interest includes a significant part of Nunavut’s population of Common Eiders. Eiders occur in this area from Upingaksaaq to Aujaq, inclusive. This MVA also supports Kumlien’s Gull and Black Guillemots. Throughout the year, this MVA is an important community harvesting area for wildlife and fish, including but not limited to: Polar bears, beluga, walrus, Arctic char, common eiders and other waterfowl, ringed seals and more. -
