Abstract

In July, 1968, the bottom water on the continental shelf of the northern Bering Sea contained concentrations of suspended material in excess of 2 ppm, or 5 mg 1 (super -1) Near the Alaska mainland, concentrations were as much as fivefold greater. The material is 85 percent mineral grains and has a modal particle size of 20mu . Because of the net northward movement of the water through Bering Strait into the Chukchi Sea, the bottom water with its high silt concentration appears to be an important transport mechanism for supplying modern silt to the shelf in the Chukchi Sea.
