The international composition of the whaling fleets that sought Balaena mysticetus north of Canada before 1915 has long been a deterrent to the compilation of a complete set of voyage and catch data. Using unpublished whaling logbooks and journals, manuscript annual summaries of Dutch and British whaling, and other sources, the author assembles data annually for each of the whaling grounds of Davis Strait, Hudson Bay, and the Beaufort Sea, which indicate that more than 29,000 whales were secured. Considering gaps in the coverage and the mortality of wounded escaped whales, the total kill during the whaling period may have exceeded 38,000. This reconstruction is considered preliminary; additional research could improve the completeness and accuracy of the information.
Breeding birds of Arctic Bay, Baffin Island, N.W.T., with notes on the biogeographic significance of the avifauna

The known avifauna of the Arctic Bay area consists of 38 species, of which 22 are probable or proven breeders and 3 are permanent residents. Arctic Bay appears to be in a transition area between characteristic high arctic and low arctic forms. Eurasian or Greenlandic forms include breeding Ringed Plover and 'Greenland' Hoary Redpoll; and transient Wheatear, Red Knot and Ruddy Turnstone. The absence of several sea-associated species as breeders or even transients may be attributed to the normal late ice break-up in Admiralty Inlet.
During the spring and summer months the diet of three Inuit families living in a seal hunting camp south of Holman, N.W.T., was studied. A total of 13 food items including the most commonly eaten mammal, bird and plant species were analysed for Vitamin C in both the raw and cooked state. We document a daily intake of ascorbic acid of between 11 and 118 mg and estimate a mean dose of at least 30 mg. This is well above the levels documented in larger transitional culture villages by a recent Nutrition Canada report.
This paper examines how sea ice floes of thickness exceeding 6 m can be formed in the Arctic. Such floes have been observed by a Soviet drifting station, by a submarine at the North Pole, and at three sites in the Canadian Arctic Archipelago. The Maykut and Untersteiner model of sea ice growth predicts an equilibrium thickness of 3 m under normal conditions, but if the oceanic heat flux is set to zero and the annual snowfall is increased to 1 m growth will continue to at least 12 m thickness over tens of years. The conclusion is that thick floes grow as 'plugs' of fast ice in constricted channels of shallow water at high latitudes, and that they break out into the Arctic Ocean only after many years of growth in place. Their history in some respects resembles that of Arctic ice shelves.
Drill hole data from the Eagle River crossing by the Dempster Highway near the Arctic Circle have been interpreted on the basis of point bars formed by a migrating meander loop and dated by tree core ring counts. In the wake of the migrating meander loop, two waves of changes in the state of permafrost have penetrated downwards into the ground, associated with a downward migrating and thickening interpermafrost talik layer containing water under pressure.
The geomorphology of Teshekpuk Lake in relation to coastline configuration of Alaska's coastal plain

Observations on a drained and a partially drained lake basin adjacent to Teshekpuk Lake led to the conclusion that the drainage was a result of erosion produced by the moat-current phenomenon of Teshekpuk Lake. The processes of shoreline erosion and lake-capture seem to be responsible for the growth and configuration of Teshekpuk Lake. Similar phenomena between large lakes and the Beaufort Sea may also have influenced the shoreline configuration of vast coastal areas such as Admiralty Bay, Dease Inlet and Harrison Bay.
... This field study has shown how an impulse radar ice profiling survey can be used to survey for fresh water in isolated pools under the ice cover of arctic river deltas. ...
This paper describes the use of snow dens by polar bears during two summers on northern Baffin and Bylot Islands. More dens were found during 1976 than 1975, probably because of heavier snow during 1976. Dens were of three types, shallow surface pits, shallow dens, and deep burrows.
Northward looking - a strategy and a science policy for northern development : Science Council of Canada report no. 26 [review]

... The Council approached its study ... by (1) undertaking a review of past resource developments there and their related government policies and (2) commissioning five case studies, all dealing with large, recent projects involving non-renewable resources. It analyzes later the subject of Canadian control over the technologies used in northern development and the special problem of marine transportation of natural gas from the Arctic. ... the Science Council has produced an enormously interesting report which should serve to stimulate further analysis and discussion. ... the report's main conclusions come close to providing a reasonable and attainable northern development strategy for the forseeable future. ...
