Atlantic conveyor

Quick Reference

A system of ocean currents that plays a major role in the transport of heat from low to high latitudes and, therefore, in global climates. It is driven by the convective overturning of water near the edge of the northern sea ice, where cold, saline water sinks to the ocean floor and travels south as the North Atlantic Deep Water, eventually to the Southern Ocean. Its place is taken at the surface by warmer water flowing northward.
