Yevgeny Korotkevich Yevgeny Korotkevich Yevgeny Sergeyevich Korotkevich () (1918 – 1 February 1994) was a Soviet scientist and polar explorer, Hero of Socialist Labor, and Doctor of Geographical Sciences. He was one of the leading scientists of the Arctic and Antarctic Research Institute (AARI) in the field of glaciology and geography of polar countries. Yevgeny Korotkevich participated in and headed many Arctic expeditions. In 1947-1955, he was engaged in scientific research on New Siberian Islands, Franz Josef Land, Novaya Zemlya, Severnaya Zemlya, Spitzbergen, Kara Sea islands, Taymyr Peninsula. Since 1955, Korotkevich's scientific and organizational activity was closely associated with the studies of
Barents Sea (temperature <0 °C, salinity <35) from the north, and warm, but not very salty coastal water (temperature >3 °C, salinity <34.7). Between the Atlantic and Polar waters, a front called the Polar Front is formed. In the western parts of the sea (close to Bear Island), this front is determined by the bottom topography and is therefore relatively sharp and stable from year to year, while in the east (towards Novaya Zemlya), it can be quite diffuse and its position can vary a lot between years. The lands of Novaya Zemlya attained most of their early Holocene coastal deglaciation approximately
