| Summary: | T HIS paper reports on an aspect of the glaciological program carried out on the ice shelf of northern Ellesmere Island in 1954 that was not described previously by other members of the expedition.1 The glaciological program of the expedition to northern Ellesmere Island was supported by the Snow, Ice and Permafrost Research Establishment, Corps of Engineers, U.S. Army, to correlate with structural and stratigraphic studies conducted on ice island T3 during the period May to November 1953. Glaciological investigations were conducted principally around Ward Hunt Island, where the largest remnant of the once more extensive ice shelf exists today. The structural and stratigraphic relationships of the various ice components of the shelf were investigated because the Ellesmere ice shelf is probably the primary source area of the ice islands of the Arctic Ocean. Also, the climatic history of the area during the past periods of ice shelf formation can be deduced from these studies. Ice cores, 3 inches in diameter, were obtained with a manually operated hand corer a t selected sites on the ice shelf (Fig. 1) and in adjoining fiords |
