Litke Deep lies in which Arctic Ocean basin?

Litke Deep lies in the Eurasian Basin of the Arctic Ocean.

The Eurasian Basin is one of the Arctic Ocean’s two major divisions, separated from the Amerasia Basin by the Lomonosov Ridge. Within it, the Gakkel Ridge further divides the seafloor into the Nansen Basin and the Amundsen Basin. Litke Deep is associated with the southwestern part of the Eurasian Basin.

Litke Deep reaches roughly 5,449 metres below sea level. It was located in 1955 during an expedition by the Soviet icebreaker Fyodor Litke and was named for the Russian explorer and naval officer Fyodor Petrovich Litke.

A frequent mix-up is with Amundsen Basin, which is also part of the Eurasian Basin and is described as the deepest basin of the Arctic Ocean. Litke Deep, however, is the deepest point within the Eurasian Basin itself. It is also discussed in connection with Earth’s polar flattening: despite being shallower than Challenger Deep by depth below sea level, its high-latitude position places it closer to Earth’s center.
