Statement of the problem. It was the purpose of this study (1) to describe the meteorological conditions on the Barnes Ice-cap during the months of June, July and August 1950; (2) to describe the ablation in that period; and (3) to show the relationship between ablation and meteorological conditions. Importance of the study. Nothing has been known about the climate of the ablation period on any Canadian glacier or ice-cap. Wood noted that previous to 1948 it was difficult to recall a single example of studies carried out in North America and devoted to the great areas of snow accumulation. In the systematic investigation of glaciers it isimperative that glaciologic and meteorologic research go hand in hand, since the problems of the two fields are intimately joined — precipitation with alimentation of the glaciers, interior temperature of ice and firn with air temperatures. As pointed out by Ahlmann, glaciology requires meteorological observations of a special kind. General and local climatological information is necessary to determine the ablation, with observations from the glacier surface itself.[...]
