ICE COVER DEFORMATION AT ADAMS ISLAND, WINTER 1982-1983

Measurements of horizontal movements of the ice cover near Adams Island, March to June 1983, and in Eclipse Sound, December 1982 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 to the minus 10th power times s to the minus one power, with a maximum of 10 to the minus 8th power times s to the minus one power. Similar strain values were obtained on Eclipse Sound. Movement rates at Eclipse Sound were of the same magnitude as those at Adams Island, but the direction was quite different. Maximum calculated and measured ice pressures were 500 and 140 kPa, respectively.
