  • Diamond Jenness (1886-1969)
    Diamond Jenness (1886-1969) HENRY B. COLLINS and WILLIAM E. TAYLOR Jr. Canada’smost distinguished anthropologist, Dr. Diamond Jenness, formerly Chiefof the Division of Anthropology, National Museums of Canada, and Honorary Associate of the Arctic Institute of North America, died peacefully at his home in the Gatineau Hills near Ottawa on 29 November, 1969. He was one of that rapidly-vanishing, virtually extinct kind - the all round anthropolo- gist, who, working seriously, turned out first-class publications in all four major branches of the discipline : ethnology, linguistics, archaeology, and physical anthropology. One must also add a fifth: applied anthropology, a fitting designa- tion for theseries of monographs on Eskimo administration in Alaska, Canada, and Greenland which he wrote after his retirement and which were published by the Arctic Institute between 1962 and 1968. Diamond Jennesswas born in Wellington,New Zealand, on 10 February 1886, and attended Victoria University College, one of the four branches of the University ofNew Zealand, wherehe graduated withfirst class honours in classics in 1908. Later he studied at Balliol College, Oxford, under one of the outstanding ethnologists of the time, Professor R. R. Marett. He received both a B.A. in Lit. Hum. and a diploma in Anthropology at Oxford in 1911. In 191 1-12 he was designated Oxford Scholar in Papua and was sent by the Uni- versity to make anthropological studies among the Northern d’Entrecasteaux, a primitive tribe dwelling on the islands of the D’Entrecasteaux Archipelago off the east coast of New Guinea. The results of this first field-work were published by Oxford University (1 920a).

    Compendium of Research in the Northwest Territories 2014 www.nwtresearch.com This publication is a collaboration between the Aurora Research Institute, the Department of Environment and Natural Resources, Fisheries and Oceans Canada and the Prince of Wales Northern Heritage Centre. Thank you to all who submitted a summary of research or photographs, and helped make this publication possible. Editor: Ashley Mercer Copyright © 2015 ISSN: 1205-3910 Printed by Aurora Research Institute Foreword Welcome to the 2014 Compendium of Research in the Northwest Territories. This year marked a special anniversary for the Aurora Research Institute and northern research. Fifty years ago, the Inuvik Research Laboratory was built and has served as a hub for research in the western arctic ever since. The Lab, as it was known, was first built as an initiative of the Canadian federal government in the newly established community of Inuvik. It remains on the same site today, but in 2011, a new modern multi-purpose facility opened to continue to support research in the north. We have included a brief history of the Lab and its impact in this edition of the Compendium to mark its long lasting importance to many researchers and community members. As part of the 50th anniversary celebration, the Aurora Research Institute team undertook a full set of NWT-wide celebrations. We celebrated the history, capacity and growth of research in the NWT that touched all corners of the territory and beyond. We honoured the significant scientific contributions that have taken place in the NWT over the past 50 years, and the role of NWT researchers, technicians and citizens in these accomplishments.

  • Frederick J. Krabbé, Last Man to See HMS Investigator Afloat, May 1854
    The Journal of the Hakluyt Society January 2017 Frederick J. Krabbé, last man to see HMS Investigator afloat, May 1854 William Barr1 and Glenn M. Stein2 Abstract Having ‘served his apprenticeship’ as Second Master on board HMS Assistance during Captain Horatio Austin’s expedition in search of the missing Franklin expedition in 1850–51, whereby he had made two quite impressive sledge trips, in the spring of 1852 Frederick John Krabbé was selected by Captain Leopold McClintock to serve under him as Master (navigation officer) on board the steam tender HMS Intrepid, part of Captain Sir Edward Belcher’s squadron, again searching for the Franklin expedition. After two winterings, the second off Cape Cockburn, southwest Bathurst Island, Krabbé was chosen by Captain Henry Kellett to lead a sledging party west to Mercy Bay, Banks Island, to check on the condition of HMS Investigator, abandoned by Commander Robert M’Clure, his officers and men, in the previous spring. Krabbé executed these orders and was thus the last person to see Investigator afloat. Since, following Belcher’s orders, Kellett had abandoned HMS Resolute and Intrepid, rather than their return journey ending near Cape Cockburn, Krabbé and his men had to continue for a further 140 nautical miles (260 km) to Beechey Island. This made the total length of their sledge trip 863½ nautical miles (1589 km), one of the longest man- hauled sledge trips in the history of the Arctic. Introduction On 22 July 2010 a party from the underwater archaeology division of Parks Canada flew into Mercy Bay in Aulavik National Park, on Banks Island, Northwest Territories – its mission to try to locate HMS Investigator, abandoned here by Commander Robert McClure in 1853.3 Two days later underwater archaeologists Ryan Harris and Jonathan Moore took to the water in a Zodiac to search the bay, towing a side-scan sonar towfish.

  • Annual Report: October 1, 2014 Assessing the Impact of Small, Canadian Arctic River Flows to the Freshwater Budget of the Canadian Archipelago Matthew B
    Annual Report: October 1, 2014 Assessing the impact of small, Canadian Arctic River flows to the freshwater budget of the Canadian Archipelago Matthew B. Alkire, University of Washington Assessing the impact of small, Canadian Arctic river flows to the freshwater budget of the Canadian Archipelago (or SCARFs) is a scientific research project funded by the National Science Foundation (USA). The purpose of this project is to collect water samples from seven different rivers and their adjoining estuaries throughout the Canadian Arctic Archipelago (see Fig. 1) in order to determine whether or not their chemical signatures differ from larger North American rivers such as the Mackenzie and Yukon Rivers. Five of the rivers are located within Nunavut, Canada: the Coppermine River (near Kugluktuk), Ellice River (~140 km southeast of Cambridge Bay), Back River (~180 km southeast of Gjoa Haven), Cunningham River (~77 km southeast of Resolute Bay on Somerset Island), and Kangiqtugaapik River (near Clyde River, Baffin Island). Two of the rivers are located within the Northwest Territories, Canada: the Kujjuua River (located approximately 67 km northeast of Ulukhaktok on Victoria Island) and Thomsen River (specifically near the mouth of the river where it empties into Castel Bay, on Banks Island). Figure 1. Map of the Canadian Arctic Archipelago. The red stars indicate the mouths of the rivers sampled during this study: (1) Coppermine R., (2) Ellice R., (3) Back R., (4) Kuujuua R. (Victoria Island), (5) Thomsen R. (Banks Island), (6) Cunningham R. (Somerset Island), and (7) Clyde R. (Baffin Island). The Coppermine, Ellice, and Back Rivers are located on the mainland of Nunavut.

  • 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’).

Global economies are changing, new markets are growing, and international focus is shifting north – and we are poised to take full advantage of this incredible opportunity. Our vast natural resource base continues to provide the backbone to our territorial economy and provide opportunities to our residents. The NWT exports approximately $3 billion in diamonds and oil annually. However, signifi cant potential remains. Last year industry bid over $500 million in the Sahtu Region for land parcels that will be explored for oil potential. The rugged, pristine and isolated nature of the Northwest Territories is also a perfect fi t for the large and growing international tourism market – tourism contributes $100 million annually to our economy, and, like our resource industry, it is on the brink of tremendous growth. Our smaller industries are also capitalizing on the unique Northern setting.

  • Diet of Arctic Wolves on Banks and Northwest Victoria Islands, 1992-2001
    Diet of Arctic Wolves on Banks and Northwest Victoria Islands, 1992-2001 Nicholas C. Larter Department of Environment and Natural Resources Government of the Northwest Territories 2013 Manuscript Report No. 230 The contents of this paper are the sole responsibility of the author. i ii ABSTRACT As part of a larger study, wolf stomachs were collected from entire wolf carcasses collected by local harvesters from Sachs Harbour (71°59’N 125°15’W) on Banks Island from 1992-2001, and from Ulukhaktok, formerly Holman (70°45’N 117°42’W) on Northwest Victoria Island from 1998-2001. Wolf scats were collected opportunistically during field research trips conducted on Banks Island from 1993-2001 and on Northwest Victoria Island from 1998-1999. A total of 129 stomachs and 38 scats from Banks Island, and 30 stomachs and two scats from Northwest Victoria Island were analyzed macro and microscopically for hair, feather, and bone fragments of prey items. Prey items were identified as closely as possible to species. Seventeen stomachs were empty. Remains of muskoxen (Ovibos moschatus) predominated being found in 90% of 115 and 88% of 27 stomachs from Banks Island and Northwest Victoria Island, respectively, and 87% of 38 and 100% of two scats from Banks Island and Northwest Victoria Island, respectively. Peary caribou (Rangifer tarandus pearyi), collared lemming (Dicrostonyx torquatus), Arctic hare (Lepus arcticus), Arctic fox (Alopex lagopus), snow goose (Chen caerulescens), ptarmigan (Lagopus spp.), and plant material were also found in stomachs and scats; however, only Peary caribou and collared lemming occurred in ≥5% of either stomachs or scats.

Box 377 Kugluktuk, NU X0B 0E0 2Integrated Ecological Research, Nelson, BC NUNAVUT DEPARTMENT OF ENVIRONMENT WILDLIFE RESEARCH SECTION KUGLUKTUK, NU Executive Summary Dolphin and Union (DU) Caribou (Rangifer tarandus groenlandicus x pearyi) have a large distribution covering Victoria Island (Nunavut and Northwest Territory) and the northern region of the Canadian mainland in Nunavut. The DU Caribou calve and summer on Victoria Island, resulting in the sharing of the northwestern extents of their seasonal ranges with Peary Caribou (Rangifer tarandus pearyi). While Peary Caribou winter on Victoria Island, the DU Caribou generally display migratory behavior by crossing the sea-ice of the Coronation Gulf to winter on the Canadian mainland. Once on the mainland, DU caribou over-winter with other tundra- wintering caribou in the eastern part of their winter range. In addition to this specific movement and seasonal range, the DU Caribou can also be distinguished, with certainty, genetically from other caribou herds (Peary Caribou and Barren-ground Caribou), highlighting the conservation importance of this herd. A coastal survey methodology, originally developed by Nishi (2004), has been used to estimate the DU caribou since 1997 as they physically separate from the Peary caribou in the fall. This methodology is based on hunter observations and Inuit Qaujimajatuqangit of Dolphin and Union Caribou gathering during rut into a narrow band on the southern coastline of Victoria Island.

  • 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.

BITZ Department of Atmospheric Sciences, University of Washington, Seattle, Washington (Manuscript received 26 June 2007, in final form 22 January 2008) ABSTRACT Rain on snow (ROS) events are rare in most parts of the circumpolar Arctic, but have been shown to have great impact on soil surface temperatures and serve as triggers for avalanches in the midlatitudes, and they have been implicated in catastrophic die-offs of ungulates. The study of ROS is inherently challenging due to the difficulty of both measuring rain and snow in the Arctic and representing ROS events in numerical weather predictions and climate models. In this paper these challenges are addressed, and the occurrence of these events is characterized across the Arctic. Incidents of ROS in Canadian meteorological station data and in the 40-yr ECMWF Re-Analysis (ERA-40) are compared to evaluate the suitability of these datasets for characterizing ROS. The ERA-40 adequately represents the large-scale synoptic fields of ROS, but too often has a tendency toward drizzle. Using the ERA-40, a climatology of ROS events is created for thresholds that impact ungulate populations and permafrost. It is found that ROS events with the potential to harm ungulate mammals are widespread, but the large events required to impact permafrost are limited to the coastal margins of Beringia and the island of Svalbard.
