 Labrador Sea

The Labrador Sea is a North Atlantic basin between Greenland and northeastern North America, studied as a site of deep ocean convection. Winter surface heat loss can increase near-surface water density until mixing reaches much deeper layers, forming Labrador Sea Water.

Repeated temperature and salinity profiles distinguish deepening convection from ordinary seasonal surface changes. The resulting water spreads into the wider circulation and helps ventilate the ocean interior. The depth of mixing varies between years; a single winter or one observing station cannot characterize the entire overturning circulation.^[ref]

The Labrador Sea is a body of water located between Greenland and the northeastern coast of Canada, specifically Labrador and Newfoundland. It is part of the North Atlantic Ocean and is characterized by its cold waters and significant oceanographic importance. The sea plays a crucial role in the global climate system, particularly in the processes of ocean circulation and thermohaline circulation, which are influenced by the mixing of warm and cold water currents.
