Aleutian Basin

[1] Subduction of the Kula Plate came to a halt following the formation of the Aleutian Trench situated to its south.

[1] The deep-water part of the Bering Sea is separated into the Commander Basin and Bowers basins by the submarine Shirshov Ridge and Bowers Ridge.

The Commander Basin occupies the western part of the Bering Sea, with the Shirshov Ridge on its eastern border.

The Bowers Ridge extends in the form of an arc over approximately 900 km from the Aleutian Islands Arc to the northwestern termination, where it meets Shirshov Ridge.

This former island arc, Bowers Ridge, is a prominent semi-circular-shaped geological that meets the Aleutian arc and, together with the Aleutians, bounds Bowers Basin.
