Arctic Ocean basins (these being the Pacific, Atlantic, and Indian Oceans) and where the circulation is dominated by thermohaline forcing”. The Arctic Ocean has a total volume of 18.07×10 km, equal to about 1.3% of the World Ocean. Mean surface circulation is predominately cyclonic on the Eurasian side and anticyclonic in the Canadian Basin. Water enters from both the Pacific and Atlantic Oceans and can be divided into three unique water masses. The deepest water mass is called Arctic Bottom Water and begins around depth. It is composed of the densest water in the World Ocean and has two main sources: Arctic
Litke Deep Litke Deep Litke Deep () is an oceanic trench in the Arctic Ocean. It is the deepest known point in the Arctic Ocean. It is the 20th deepest oceanic trench in the world. The Litke Deep is located in the southwestern part of the Eurasian Basin south of the underwater ridge Gakkel Ridge roughly 350 kilometers northeast of Svalbard and roughly 220 km north of the island of Nordaustlandet. The deepest part is at 5,449 metres (17,881 feet) under sea level. The average depth in the Arctic Ocean is about 1,000 metres and more than 60 % is less than
