Arctic Ocean deepest point is Litke Deep in the Eurasian Basin, at . The two major basins are further subdivided by ridges into the Canada Basin (between Alaska/Canada and the Alpha Ridge), Makarov Basin (between the Alpha and Lomonosov Ridges), Amundsen Basin (between Lomonosov and Gakkel ridges), and Nansen Basin (between the Gakkel Ridge and the continental shelf that includes the Franz Josef Land). In large parts of the Arctic Ocean, the top layer (about ) is of lower salinity and lower temperature than the rest. It remains relatively stable, because the salinity effect on density is bigger than the temperature effect.
Nansen Academy Nansen Academy The Nansen Academy – Norwegian Humanistic Academy () is a folk high school in Lillehammer, Norway. Nansen Academy was founded as a humanist and anti-totalitarian institution. The school was named after polar explorer, scientist, author and humanist Fridtjof Nansen (1861-1930). His work embodied essential elements of humanism: active love of one’s neighbour and freedom of thought. The school was established in 1938 by Kristian Vilhelm Koren Schjelderup, Jr. (1894–1980) Bishop of the Diocese of Hamar together with future Norwegian Resistance Movement members Anders Platou Wyller (1903-1940) and Henriette Bie Lorentzen (1911–2001).
