Ice cover deformations at Adams Island, winter 1982-1983
Measurements of horizontal movements of the ice cover near Adams Island, March to June l983, and in Eclipse Sound, December l982 to June 1983, indicate no apparent coupling between movement direction and wind or current. Average strain rates in the plane of the ice cover were 10 -10 s -1, with a max...
