Severnaya Zemlya

Severnaya Zemlya (Russian: Северная Земля, lit. 'Northern Land', pronounced [ˈsʲevʲɪrnəjə zʲɪmˈlʲa]) is a 37,000 km² (14,000 sq mi) archipelago in the Russian high Arctic. It lies off Siberia's Taymyr Peninsula, separated from the mainland by the Vilkitsky Strait. This archipelago separates two marginal seas of the Arctic Ocean, the Kara Sea in the west and the Laptev Sea in the east.

Severnaya Zemlya was first noted in 1913 and first charted in 1930–32, making it the last sizeable archipelago on Earth to be explored. Administratively, the islands form part of Russia's Krasnoyarsk Krai. In Soviet times there were a number of research stations in different locations, but currently there are no human inhabitants in Severnaya Zemlya, except for the Prima Polar Station near Cape Baranov.

The largest glacier in the Russian Federation, the Academy of Sciences Glacier, is located in Severnaya Zemlya. Until recently, ice joined the islands to Eurasia, even at its smallest extent during the late summer melt season, blocking the Northeast Passage between the Atlantic and the Pacific. By the late summer of 2012, however, due to Arctic sea ice decline the permanent ice had reached a record low extent and open water appeared to the south of the archipelago.
