OoUege 01 Te:eaa ABSTRACT Fifty-two marine sediment samples from Prince of Wales Strait and Amundsen Gulf have been analyzed for properties suoh as grain size and rook and mineral composition. It appes.rs that the distribution of the various sediment types in the area investigated is markedly influenced by both stream location and sea ice. ." INTRODUCTION The marine sediments described in this paper were collected during the 1953 Beaufort Sea Expedition, sponsored by the United States Navy. This was the first expedition to systematically invest­ igate the marine deposits of Amundsen Gulf and Prince of Wales Strait (see Fig. 1). Geographic Description. Previous expeditions have provided con­ siderable information concerning the geography and geology of this general area (Carsola, 1954a; Washburn, 1947; Chipman and Cox, 1924). The mainland east of the Mackenzie River to Cape Bathurst is a fiat swampy plain, and from Dolphin and Union Strait east to Sherman Inlet on Adelaide Peninsula it is generally low and deeply indented. But in the vicinity of Tree River and Cape Barrow on Coronation Gulf the terrain is rugged. The Coppermine is the largest of several rivers in this area. Prince of Wales Strait separates Banks Island from Victoria Island. In the southern portion of Victoria Island and along Prince 1 Contribution from the Department of Oceanography and Meteorology of the A. & M. College of Texas.

Canadian Arctic. Albert Sound the topography is generally under 300 feet, but inland elevations of about 2000 feet have been reported. In the Walker Bay area, steep shores rise to over 1000 feet. The near-shore area along Prince of Wales Strait is generally under 200-300 feet, these elevations increasing inland. The southern part of Banks Island from Nelson Head east to Cape Lambton and then north to Thesiger Bay is characterized by steep cliffs composed of a sedimentary sequence capped with basalt which may rise to more than 1500 feet; in the southwest comer there is a plateau over 2000 feet high. The coast region from Nelson Head to DeSalis Bay and eastward is low-lYing while inland the elevation increases gradually to a maximum of about 1000 feet. The Prince of Wales Strait shore area is generally under 200 feet. Both Banks and Victoria Island show evidence of glaciation (Washburn, 1947; Porslid, 1950). An esker has been observed on the high plateau of Nelson Head and Cape Lambton, and eskers, striated stones, and erratics have been found on southern and eastern Banks Island. In the Walker Bay region of Victoria Island, 1958] Bader and Henry: Marine Sediments in the Arctic 37 also glaciated, the high plateau to the north has in the limestone many large striations which trend northwestward. Terraces on both islands up to approximately 600 feet indicate isostatic adjustment following glaciation. Although it is known that the lower terraces are former strand lines, many of the higher terraces are of doubt­ ful origin. Oceanographic Description. The region eastward from Icy Cape, Alaska, including Amundsen Gulf, is covered by unnavigable shore­ bound sea ice for about 9 to 10 months of the year (U. S. Hydro­ graphic Office, 1946), and permanent polar ice is located approx­ imately 40 to 60 miles north of Point Barrow, Alaska. In July the heavy ice begins to dissipate in the southern Chukchi Sea, at the mouth of the Mackenzie River, and south of Victoria Island in Dolphin and Union Strait and Coronation Gulf. During August a narrow strip of navigable ice appears along the continental shore from the Chukchi Sea to Hershell Island, just east of the Mackenzie River mouth. The strip gradually widens eastward and Amundsen Gulf is usually ice-free in August. In early August 1953 it was neces­ sary to search for open leads only a few miles from shore in the region east of the Mackenzie River. By September the ice begins to move back against the shore and may become land-fast at Point Barrow, although Amundsen Gulf is usually still open. Prince of Wales Strait mayor may not be navigable. In October the sea again becomes ice-bound. The wind direction and force is an important factor in the ice distribution. In August and September of 1953, during periods of north and northwest winds, Prince of Wales Strait was generally ice-bound, but during periods of southeast winds or calm weather the ice was either absent or scattered. Wave action is usually negligible due to the relatively short fetch. The tides are mostly under one foot although Stefansson (1921) has recorded 6- to 8-foot wind tides along the western coast of Banks Island due to strong west winds. Low tides may also be associated with east winds. The currents are poorly developed and not well understood (U. S. Hydrographic Office, 1951; Carsola, 1954a). In the western Arctic most of the soundings have been obtained .s. off the Alaskan coast. Carsola (1954a, 1954b) has discussed the relief of the Continental Shelf and adjacent areas of the Beaufort and Chukchi seas. The Continental Shelf of the Beaufort Sea, ter- 38 J()urnal 01 Marine Research [17 minating at about 30 to 40 fathoms, shows the effects of local glac­ iation just west of Amundsen Gulf. Shelf glaciation is to be expected in the eastern Beaufort Sea since there is ample evidence of glac- ~ iation on the southern parts of Banks and Victoria Island. Amundsen Gulf, approximately 500 to 700 feet deep, is appar­ ently a trough-like basin oriented WNW. Prince of Wales Strait, with a maximum depth of about 240 to 450 feet, is much shallower than Amundsen Gulf or McClure Strait. Sediment lee-Rafting. Ice-rafting of one type or another in the Arctic has been discussed by Nares (1878), Bancroft (1905), Stefans­ son (1921), Kindle (1924), Chipman and Cox (1924), Nichols (1936), Deevey (1939), Washburn (1947), LaFond et ale (1949), Emery (1949), Fletcher (1950), Carsola (1954a), and others. Ice-rafting is capable of transporting sediment far from its source. In the Chukchi Sea, mud-laden ice was observed almost 200 miles from the nearest land. In early August 1953 brown sediment-laden ice was abundant in the vicinity of the Mackenzie River mouth, but in September it had disappeared; it had melted or been carried away by winds and a westerly current. Ice islands provide an excellent means for long range sediment transport. These islands are fragments of shelf ice from Ellesmere Island over 1000 miles to the east (J. O. Fletcher, personal commun­ ications). One such island, 1/4mile wide by 1/2mile long and about 100 feet thick, was observed in Prince of Wales Strait. The surface was coated with a layer of micaceous sediment. The schists and gneisses on northern Ellesmere Island may have been the source of this sediment. The sediments may become a part of sea ice by the following principal means: 1) Grounded sea ice freezes at the base and includes sediments. Repeated melting of the upper surface and refreezing at the base gradually bring sediments to the surface. 2) Land-fast ice picks up beach sediments on the bottom and landslides or slumping add material to the ice surface. Numerous instances of this were observed in Prince of Wales Strait; in some cases till-like soil completely covered the ice. 3) Since river ice breaks up earlier in the spring than sea ice, river waters flow out over the sea ice and deposit their load. Exam­ ples of this were observed at the mouth of small intermittent 1958] Bader and Henry: Marine SedimentB in the Arctic 39 streams on the east side of Banks Island.

    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).

  • 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.

    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.

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.

    ARCTIC VOL. 35. NO. 4 (DECEMBER 1982) P. 519-523 Bowhead Whale Distribution in the Southeastern Beaufort Sea and Amundsen Gulf, Summer 1979 KATHERINE W. HAZARD' and JAMES C. CUBBAGE' ABSTRACT. The distribution of bowhead whales in the southeastern Beaufort Sea and Amundsen Gulf was determined from observa- tions aboard commercial resupply vessels. Fifty-four to sixty-two whale sightingswere recorded on the 2150 km (1 160 nm) of transects. Distribution of whale sightings along transects was clumped. The proportion of whales seen near ice was significantly greater than the proportion of transect surveyed near ice. Our observations and interviews indicate that bowheads are seen over a period of several weeks in many areas where they are seen annually. Both the locations and seasonality of whale Occurrence appear similar to distribution patterns extracted from sightings of nearly a century ago.

    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.
