In the centre, there is a deep pit called the Baffin Basin, reaching 2,136 m (7,008 ft) (see depth map), which is mostly covered in silt. Currents form a cyclonic circulation . On the eastern periphery, in summer, the West Greenland Current transports water from the Atlantic Ocean to the North.
[7] [8] Because of the scarce freshwater inflow and extensive evaporation, which is promoted by shallow water and warm climate, the bay has a relatively high water salinity reaching 75‰ (parts per thousand) in its northern part. [9] Between 1946 and 1948 and in 1968, the salinity level in the bay exceeded 100‰ killing much fish in the area ...
Baffin Basin. The Baffin Basin is an oceanic basin located in the middle of Baffin Bay between Baffin Island and Greenland. With a maximum depth of over 2,700 m (8,900 ft), the basin represents the deepest point of Baffin Bay. The basin formed as a result of seafloor spreading at the time of the opening of Baffin Bay around 56 million years ago ...
Below the Atlantic layer are Baffin Bay Deep Water and Baffin Bay Bottom Water, both of which are cold and saline. On a net annual basis, approximately 1.7 Sv of water flows out of the Arctic Ocean through Baffin Bay, making the bay the second most important conduit between the Arctic Ocean and the rest of the world's oceans.

It lies between mid-western Greenland and Baffin Island in Nunavut, Canada. To the north is Baffin Bay. The strait was named for the English explorer John Davis (1550–1605), who explored the area while seeking a Northwest Passage. By the 1650s it was used for whale hunting.
Nares Strait (Danish: Nares Strædet; French: Détroit de Nares) is a waterway between Ellesmere Island and Greenland that connects the northern part of Baffin Bay in the Atlantic Ocean with the Lincoln Sea in the Arctic Ocean. From south to north, the strait includes Smith Sound, Kane Basin, Kennedy Channel, Hall Basin and Robeson Channel.
It is initiated by the East Greenland Current and continued by the West Greenland Current, which brings warmer, more saline waters northwards, along the Greenland coasts up to the Baffin Bay. Then, the Baffin Island Current and Labrador Current transport cold and less saline water southward along the Canadian coast. These currents carry ...
Baffin Bay and the Hudson Strait are the largest freshwater contributors to the Labrador Current. [5] The Hudson Strait is a narrow channel that is about 400 km long and is the opening to the Hudson Bay System, which is connected to the Labrador Sea, and contributes 50% of the freshwater transport of the Labrador Current.
