Ice interaction with Adams Island, winter 1982-83
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...
