Peter 'the Great' Bay

This broad gulf opens into the northwestern Sea of Japan along a deeply indented coast. A long peninsula and an adjoining chain of islands divide its inner waters into the Amur and Ussuri bays. Other islands lie farther offshore, among them Askold and Putyatin. Warm and cold currents meet in these waters, while the shallow inner bays freeze in winter and shelter different marine life as the seasons change.
