Account of the Ellesmere Ice Shelf Expeditions, organized by the Defence Research Board and Geological Survey of Canada. On reconnaissance Apr.-Aug. 1953, G.F. Hattersley-Smith and R.G. Blackadar made glaciological and geological observations west from Alert to Markham Bay (including Ross River and Feilden Peninsula), east to Cape Sheridan, and southwest along Wood River toward the United States Range. In 1954 (Apr.-Sept.), G.F. Hattersley-Smith, E.W. Marshall, A.P. Crary, and R.L. Christie made their main base on the ice shelf at Ward Hunt Island (83 05 N, 75 W), from which trips were made east to Cape Albert Edward and Cape Columbia, and west to Kruger Island on the edge of Nansen Sound, completing glaciological and geological reconnaissance of the north coast of Ellesmere. On the ice shelf near the Ward Hunt Island base, geological, geophysical, glaciological and oceanographic investigations, survey and leveling work, and meteorological observations were carried on. Reports are made on the glaciological work by G.F. Hattersley-Smith; geophysical and oceanographic studies, by A.P. Crary; and geological observations, 1954, by R.L. Christie. New place names (11) submitted to the Canadian Board on Geographical Names, also records and relics recovered from cairns of earlier expeditions, are reported. The account is introduced by a useful summary of parties visiting Northern Ellesmere 1876-1951, and of work on ice island T-3.
Contains account of observations and counts made at the Barrow base camp, an 80-acre area, and on the adjacent tundra on the mass movements of the brown lemming. Age composition; male-female ratio; condition of digestive tract, adrenals, reproductive organs, etc., were studied. Causes of this emigration (changes in food supply and cover) as well as similar movements earlier in this region and in Scandinavia are discussed.

Notes on the behaviour of three yearlings kept two and a half months in 1954 in a dry environment at Amchitka in the Aleutians. Their sleeping, preening, reaction to man and feeding habits, drinking, locomotion, handling, food and sociability voice, etc., are discussed in detail. Their anatomy and environment in captivity are also discussed: water for swimming was found desirable, if not necessary. Results of physiological investigations are reported by D.E. Stullken and C.M. Kirkpatrick, q.v.
"The vertical temperature profile through a section of the air-snow-ice system was measured daily off Point Barrow (Alaska) during the late winter and early spring of 1950. Nine thermistors were spaced from 2 m above the snow to a depth of 85 cm in the ice. Four control areas with varying thicknesses of snow cover were used to measure simultaneously the different amounts of ice growth. Snow temperatures at 7 cm varied only 9 C (-7 to -16 C) while the air temperatures varied from -10 to -32 C. The ice growth in the absence of a snow cover was nearly 50 percent greater than under 2 m of snow. Present knowledge is not sufficient to predict ice thickness from snow-cover thickness, but results of earlier studies suggest that a hyperbolic relationship exists."--SIPRE.
The items include: 1) a brief history of the Danish Arctic Station at Godhavn, which is the oldest permanent biological laboratory in the Arctic, and information on how to apply to use the station by M. Westergaard; 2) details on the design and construction of a new Danish Arctic ship, the M.V. Magga Dan; 3) William S. Laughlin's report on a study by C.S. Chard concerning the Kamchadal culture and its relationship to the Asiatic and New World populations; and 4) a list of the main speakers and the titles of their talks that will be presented at the Symposium on Arctic and Alpine Tundras in East Lansing, Michigan.
By the death of Dr. Robert Charles Wallace on 30 January 1955, the Arctic Institute of North America lost more than its Executive Director. The staff and the Governors lost a warm friend. The north lost one who knew it well and who had served it faithfully in a variety of ways during his forty-five years in Canada. So well and so affectionately was he known as "Wallace of Queen's" that his links with the north of Canada were somewhat naturally overshadowed in the minds of many of his friends. To some it seemed strange that, after his distinguished service to Queen's University, and at a time in life when many men would have cast all official duties aside, he willingly accepted the invitation to serve the Arctic Institute in its senior administrative post. But those who knew him well were not surprised nor were they in any doubt that what was supposed to be a "half-time job" was to be for him a labour of love upon which no time limit could be imposed. ...
