A shallow section of the Arctic Ocean, off N Russia, between Severnaya Zemlya and Novaya Zemlya. It has an average depth of 420 ft (128 m). It receives the Ob, the Yenisei, the Pyasina, and the Taimyra rivers, and is important as a fishing ground. Its main ports are Novyy Port and Dikson, but the ice-locked sea is navigable only during August and September.
