Frost-table and Thaw Depths in the Littoral Zone near Peard Bay, Alaska
ABSTRACT. Measurements were made of thaw depths and of sub-surface tem-peratures along four beach profiles, between late May and late August. On the upper beach levels, thaw proceeded rapidly following the disappearance of surface snow, but then became much slower. Near the water line, thaw was dela...
