Atlantic Meridional Overturning Circulation

Quick Reference

The thermohaline oceanic circulation system in the North Atlantic, in which warm water is carried north and east by the Gulf Stream and North Atlantic Current, with cold water returning south at depth. The circulation, which forms part of the Great Ocean Conveyor Belt, is driven by the intense evaporation off Labrador and Greenland, with a consequent increase in density and salinity, the water sinking to become North Atlantic Bottom Water. See also rapid.
