Abstract
Along the gravel beaches of the south west portion of Cornwallis Island in the Canadian archipelago in about 76 degrees 45 feet N and 95 degrees 00 feet W, a belt of fresh water ice anchored to the sea bed has been observed. It is suggested that it forms from fresh water extruded through the sea bed. The fresh water reaches the sea bed by way of a duct formed between the permafrost layer and the frozen upper layer of the wet beach gravel which appears with the first frost. The belt of ice is widely distributed along 30 km of beach front, which indicates that the phenomenon may be common along gravel beaches in many areas of the Arctic. Since the belt of anchor ice protects the beach from disturbance by moving sea ice, a more intensive study is indicated beacuse of the rapidly increasing industrial use of the arctic beach zone.
