description Aleutian Basin Overview
The Aleutian Basin is a deep-water basin in the Bering Sea, lying north of the Aleutian Islands and beside the Bering Sea continental shelf. It is more than 3,000 m deep and forms part of the Bering Sea's broad deep-basin system, which contrasts with the surrounding shelves that are generally less than 200 m deep. The basin is studied in marine geology and oceanography, including its sedimentary structure, deep-water circulation, and links to the physical and biological processes of the Bering Sea.
