Litke Deep

The deepest point, also referred to as Litke Deep, is 5,449 m (17,877 ft) below sea level.

[5][6][7][8][9] The Litke Deep is located in the southwestern part of the Eurasian Basin,[10] which stretches from northeastern part of Greenland past the Svalbard archipelago, Franz Josef Land and Severnaya Zemlya to the Taymyr Peninsula.

[3] Litke Deep is closer to North Pole at 82°24’ N and the difference between Earth's diameter at poles and equator is greater than the depth at Challenger Deep (10,925 m (35,843 ft) below sea level), around 11°22' north, nearer to equator with sea level also having the difference.

However, by depth below sea level, Litke Deep is not the deepest point in the Arctic Ocean.

[11] No crewed or unmanned descents have been undertaken to Litke Deep as of 2024[update].
