Abstract
A small island (200 m in diameter) is being used to study the interaction of the ice cover with the island and the response of the ice cover to the environmental driving forces. The environmental factors of wind, air temperature, current and tide were measured. Horizontal movements of the ice cover varied from 10 cm per day in March to 2 cm per day in June. The direction of movement did not correspond to wind or current direction. Average strain rates measured with small (0.3 m) gauge length strain meters and large (~100 m) triangular arrays were of the order of 10-⁹ s-¹. Direct measurements of stress and values calculated from the strain rate were of the order of 100 kPa.
