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.
The most prominent morphological features are the East Novaya Zemlya Trough and Saint Anna Trough, with depths over 500 m. The Saint Anna Trough is a main pathway for water, sediment, and ice exchange between the Arctic Ocean, the Barents Sea, and the Kara Sea. The annual river runoff into the Kara Sea is 1100–1350 km3 (including the Ob and Yenisei runoff of 400–450 and 600–630 km3, respectively). These two rivers discharge up to 13.2 and 15.8 million tons of sediment matter annually. Their discharge shows a strong seasonal variability and controls the sedimentation, biological productivity, and hydrological structure in the southern part of the sea.
Fe-Mn nodules and crusts.
