Siberian Shelf Siberian Shelf The Siberian Shelf, one of the Arctic Ocean coastal shelves (such as the Milne Ice Shelf), is the largest continental shelf of the Earth, a part of the continental shelf of Russia. It extends from the continent of Eurasia in the general area of North Siberia (hence the name) into the Arctic Ocean. It stretches to offshore. It is relatively shallow, with average depth of 100 m. A number of islands are within the shelf, including the Wrangel Island, Novaya Zemlya, and the New Siberian Islands. It is encompassed by the Kara Sea, Laptev Sea, and East Siberian
East Siberian Sea the sea centre, reaching 31–32‰ at its northern outskirts. Salinity decreases in summer by some 5‰ due to the snow melting. It also decreases by some 5–7‰ from the sea bottom to the surface. There are constant currents at the sea surface directed from west to east. They are weak and thus can temporarily change direction due to the wind. The tides are semidiurnal (rising twice a day) with the amplitude between 5 and 25 cm. The tidal wave weakens toward the coast due to shallow waters. The sea level is maximal in summer, due to the river runoff, and
