Fall ice drift in Nares Strait, as observed by sideways-looking airborne radar   /   Dunbar, M.

From Sideways-Looking Airborne Radar (SLAR) imagery of sea ice obtained on three flights during the week of 19 to 26 Oct. 1976 it is possible to track floes throughout Nares Strait over periods of days and, on one occasion, hours. The data are interpreted in the light of available information on ice drift, winds, and currents. The results are believed to give a fairly typical picture of ice drift characteristics in periods of northerly air flow, which is the dominant pattern in this area. The suitability of the method for acquiring drift information in other areas is also demonstrated.


Soviet timber : regional supply and demand, 1970-1990   /   Barr, B.M.

This paper investigates a specific problem, namely the ability of Soviet regional timber resources, particularly those of Northern European Russia and Siberia, to sustain the demands expected to be placed on them by world and domestic markets in 1990, the final year of the fifteen-year intermediate-future planning or forecasting period now guiding much of the national and spatial development of the Soviet economy. Contrary to the findings of other studies, this analysis suggests that the Soviet forest resource has sufficient potential to satisfy all planned domestic requirements and a large share of foreign demand in 1990, and in the years immediately following that date, if technological improvements in the comprehensive use of roundwood continue to be made in the Soviet wood-processing industry. When expected 1990 Soviet timber exports are compared to the United Nation's estimate of world demand for Soviet timber in the year 2000, the USSR appears able to fulfill but not to overwhelm most potential world demand for its timber although world markets will likely continue to secure a significant portion of their coniferous timber needs from North American, especially Canadian forests.


Effects of storm surges on the Beaufort Sea coast, Northern Alaska   /   Reimnitz, E.   Maurer, D.K.

In 1970, a major storm surge caused by gale-force westerly winds inundated low-lying tundra plains and deltas as far as 5000 m inland and left a driftwood line as much as 3.4 m above normal sea level along the Beaufort Sea coast of Alaska. The height of the surge followed a predictable pattern and was highest along windward-facing shorelines. Coastal retreat and thermoerosion are greatly accelerated on such west-facing shores with eastward sediment transport opposite to normal littoral drift. Evidence suggests an approximate 100-year recurrence interval for similar surges, with potential for damaging the developing oil fields on the North Slope.


Recent year-to-year variations in seasonal temperatures and sea ice conditions in the eastern Canadian Arctic   /   Jacobs, J.D.   Newell, J.P.

Mean summer and winter temperatures for the 1957-1978 period have been analyzed for four eastern Arctic stations. Standard deviations on the order of 3 C in winter and 10 C in summer indicate the magnitude of the interannual variations, and these departures are found to be synchronous over the region. Several indices of sea ice severity also show significant year-to-year variations, but these are not spatially coherent. Relationships between climatic parameters and sea ice are examined in order to explain these differences.


Recent ethnographic research - upper Churchill River drainage, Saskatchewan, Canada   /   Jarvenpa, R.
Arctic, v. 32, no. 4, Dec. 1979, p. 355-365, ill., map, photos., tables

Recent developments in ethnographic research in the Upper Churchill River drainage of northwestern Saskatchewan are reviewed. These include an analysis of the spatial organization of trapping economics, and an examination of behavioral responses to current technological impact (particularly housing, imported food and machinery, and new roads) in a southern Chipewyan community. Although high-income trappers generally exploit the largest trapping areas at the greatest distances from a primary settlement, the increasing congregation of short-distance trappers near the village may be exacerbating ecological and economic instability associated with new consumer goods and purchasing habits. Another direction of research involves analysis of economic and social interactions between Chipewyan and Cree communities that shed light upon processes of inter-tribal communication, symbiosis, enmity and identity management.


"Punch" Dickins and the origin of Canol's Mackenzie air fields   /   Barry, P.S.

Correspondence between the Canadian flyer, C.H. "Punch" Dickins, and government officials in Ottawa during the early summer of 1942 reveals that the United States Army began building an "unauthorized" military air route to Norman Wells ... much earlier than the U.S. War Department's official histories admit, and that, although Canada's Cabinet War Committee professedly knew nothing of it, certain Canadian government personnel were privy to the secret. ...


A sighting of an albino caribou in Alaska and review of North American records   /   Curatolo, J.A.
Arctic, v. 32, no. 4, Dec. 1979, p. 374-375
ASTIS record 3282

An albino caribou (Rangifer tarandus granti) calf was observed among members of the Porcupine Herd on 2 July 1976 near the Kongakut River in northeastern Alaska (69 27' N, 141 30' W). It had snow-white fur and pink eyes. Hooves and muzzle were light-colored. The calf's behavior was similar to normally pigmented calves. This individual was the only albino observed in a group of 15,000 to 20,000 individuals. Observations were made for approximately two minutes at 300 m using a 45 power spotting scope. Eight other people observed the calf. ...
