Abstract

Freezeup conditions in the beach and nearshore zone at Radstock Bay in the fall of 1971 are described and provide a basis for a more general discussion of the factors involved. The timing and duration of the freezeup process and the type of ice conditions produced at the shore are considered. The basic control on the process is the rate at which temperature declines in the fall; but wind and wave conditions, the type and amount of pack ice present both offshore and at the beach, and the amount of snowfall in the period are of major significance. In 1971, the final immobilization of the beach did not occur until October 4, though the process began a month earlier; storm-wave action and the grounding of resistant pack ice at the shore were important.
