The 'Bering Canyon' is the longest of the
Bering Sea canyons; it extends about 400 km across the Bering shelf and slope. It is confined at its eastern edge by the
Aleutian Islands. The width of the canyon at the shelf break is about 65 km, only about two-thirds that of the
Zhemchug Canyon and
Navarin Canyons, but because of its great length, the Bering Canyon has the largest area. At a depth of 3200 m, the Bering Canyon
thalweg reaches the
Aleutian Basin, where a low-relief submarine channel-lobe system has developed.
