Using a Geospatial Approach to Evaluate the Impacts of Shipping Activity on Marine Mammals and Fish in Arctic Canada
Using a Geospatial Approach to Evaluate the Impacts of Shipping Activity on Marine Mammals and Fish in Arctic Canada Thesis Master of Science in Geography with Specialization in Science, Society and Policy Jenna Joyce April 2018 Submitted to: Dr. Jackie Dawson, Supervisor, Department of Geography, University of Ottawa Dr. Luke Copland, Department of Geography, University of Ottawa Dr. Michael Sawada, Department of Geography, University of Ottawa Department of Geography, Environment and Geomatics University of Ottawa © Jenna Joyce, Ottawa, Canada, 2018 Abstract A loss in sea ice cover, primarily attributed to climate change, is increasing the accessibility and navigability of the Arctic Ocean. This increased accessibility of the Canadian Arctic, and in particular the Northwest Passage, presents important global and national shipping and development opportunities. However, increased shipping in the region also present challenges related to the environmental sustainability, sovereignty and safety, and cultural sustainability. The Low Impact Shipping Corridors (the Corridors) is currently the foundational framework for governing ship traffic within the Canadian Arctic. However, the Corridors were largely established based on historic traffic patterns and thus they do not fully consider important areas for marine mammals and fish in the region. This research addresses this important research gap by spatially identifying important areas for marine mammals and fish in the Kitikmeot region of Nunavut using both Traditional Knowledge and western science, evaluating ship tracks from 1990-2015, and geospatially identifying and evaluating areas of potential disturbance for marine mammals and fish related to vessel noise from different ship types transiting the Corridors within the study region. The results of this study indicate that all vessel types have the potential to cause behavioural disturbance to marine mammals and fish when navigating through these important wildlife areas, and that louder vessels (i.e. -

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’). -

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. -
The Final Days of the Franklin Expedition: New Skeletal Evidence ANNE KEENLEYSIDE,1 MARGARET BERTULLI2 and HENRY C
ARCTIC VOL. 50, NO. 1 (MARCH 1997) P. 36–46 The Final Days of the Franklin Expedition: New Skeletal Evidence ANNE KEENLEYSIDE,1 MARGARET BERTULLI2 and HENRY C. FRICKE3 (Received 19 June 1996; accepted in revised form 21 October 1996) ABSTRACT. In 1992, a previously unrecorded site of Sir John Franklin’s last expedition (1845–1848) was discovered on King William Island in the central Canadian Arctic. Artifacts recovered from the site included iron and copper nails, glass, a clay pipe fragment, pieces of fabric and shoe leather, buttons, and a scatter of wood fragments, possibly representing the remains of a lifeboat or sledge. Nearly 400 human bones and bone fragments, representing a minimum of 11 men, were also found at the site. A combination of artifactual and oxygen isotope evidence indicated a European origin for at least two of these individuals. Skeletal pathology included periostitis, osteoarthritis, dental caries, abscesses, antemortem tooth loss, and periodontal disease. Mass spectroscopy and x-ray fluorescence revealed elevated lead levels consistent with previous measurements, further supporting the conclusion that lead poisoning contributed to the demise of the expedition. Cut marks on approximately one-quarter of the remains support 19th-century Inuit accounts of cannibalism among Franklin’s crew. Key words: Franklin Expedition, skeletal remains, oxygen isotope analysis, lead poisoning, cannibalism RÉSUMÉ. En 1992, on a découvert un site non mentionné auparavant, relié à la dernière expédition de sir John Franklin (1845- 1848) dans l’île du Roi-Guillaume, située au centre de l’océan Arctique canadien. Les artefacts récupérés sur ce site comprenaient des clous en fer et en cuivre, du verre, un fragment de pipe en terre, des morceaux de tissu et de cuir de chaussure, des boutons et de multiples fragments de bois éparpillés, qui pourraient venir d’un canot de sauvetage ou d’un traîneau. -
