laptev sea
marginal sea of the Arctic Ocean off the coast of Northern Siberia (Russia), bounded by the Taymyr Peninsula (Poluostrov) and the islands of Severnaya Zemlya on the west and by the New Siberian Islands and Kotelny Island on the east. It is connected in the west with the Kara Sea and in the east with the East Siberian Sea. Formerly called the Siberian Sea, it was renamed in 1935 after Khariton and Dmitry Laptev, the brothers who first mapped its shores (1735-40). Its area is about 276,000 square miles (714,000 square km), the average depth 1,896 feet (578 m), and the greatest depth 9,774 feet (2,980 m)
