Transformation of the Labrador Sea Water in the subpolar North Atlantic
Development, spreading and decay of the thermohaline properties of two Labrador Sea Water (LSW) classes are described. During the development phase, a specific LSW class repeatedly mixed by winter convection in the Labrador Sea becomes colder, denser, thicker and deeper. Once convection weakens, the...

Development, spreading and decay of the thermohaline properties of two Labrador Sea Water (LSW) classes are described.
