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
