| Summary: | G LACIERS are an important element of the arctic and subarctic environment. They strongly influence meteorological and climatological conditions and have local economic significance. Glaciers are delicately responsive to subtle climatological changes, and their behaviour provides a useful means of recognizing the nature and scale of these changes depending upon the degree to which the influence of the various glaciometeorological elements is under-stood (Wallkn, 1948; Hubley, 1954; Orvig, 1954). Useful data on mean annual temperatures in remote regions can be obtained from measurement of thermal regimen in polar glaciers (Ahlmann, 1953, p. 3). Academically, study of arctic glaciers will be especially valuable if Ahlmann (1953, p. 5) is right in supposing that the great Pleistocene ice-sheets were essentially polar in behaviour and temperature regimen.
