Which sea lies north of Siberia between the Kara Sea and the East Siberian Sea? The answer is the Laptev Sea.
The Laptev Sea is a marginal sea of the Arctic Ocean along Russia’s northern coast. The Kara Sea lies to its west, while the East Siberian Sea lies to its east, making the geographic description in the question distinctive and unambiguous.
Its boundaries also include the Taimyr Peninsula, Severnaya Zemlya, and the New Siberian Islands. The sea is generally shallow over its broad continental shelf and receives enormous freshwater inflows, especially from the Lena River, one of the great rivers of the Arctic.
The name honors Russian explorers Dmitry Laptev and Khariton Laptev. Severe cold, seasonal sea ice, low salinity, and sparse settlement characterize the region. The Laptev Sea is also a major source of Arctic sea ice exported into the wider Arctic Ocean.
