Severnaya Zemlya Severnaya Zemlya Severnaya Zemlya ( (Northern Land), ) is a 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 federal subject. In Soviet times there were a number of research stations in different locations,
Severnaya Zemlya appeared to the north of the archipelago. Although located not far off the northern coast of Russia, nested among Arctic ice-locked waters, the archipelago that is now known as Severnaya Zemlya was not formally recorded until the 20th century. Earlier explorers deemed that there was a land mass in the general area of the archipelago, such as in the report by Matvei Gedenschtrom and Yakov Sannikov made in 1810 at the time of their exploration of the New Siberian Islands. Later in the 19th century Adolf Erik Nordenskiöld during the Vega Expedition sailed very close to this land in 1878
