Agulhas Current – A warm current that carries Indian Ocean water around the southern tip of Africa and into the Atlantic Ocean. Antarctic Bottom Water – In southern subpolar latitudes, rapid winter freezing produces very cold, high-density water that sinks down the continental slope of Antarctica and becomes Antarctic Bottom Water, the densest water in the open ocean. It slowly sinks beneath the surface and spreads into all the world’s ocean basics, eventually returning to the surface perhaps 1000 years later. Antarctic Circumpolar Current – The eastward-flowing current that encircles Antarctica and extends from the surface to the deep-ocean floor. It is driven by the powerful prevailing westerly wind belt; the largest volume current in the oceans. Also called the West Wind Drift. Alaskan Current – Where some of the North Pacific Current water flows to the north to and merges. Brazil Current – The warm western boundary current of the South Atlantic Subtropical Gyre. California Current – The cold eastern boundary current of the North Pacific Subtropical Gyre. Canary Current – The cold eastern boundary current of the North Atlantic Subtropical Gyre. Coastal upwelling – The movement of deeper nutrient-rich water into the surface water mass as a result of windblown surface water moving offshore. Conveyer-belt circulation – An integrated model combining deep thermohaline circulation and surface currents. Begins in the North Atlantic, where surface water carries heat to high latitudes via the Gulf Stream. During the cold winter months, this heat is transferred to the overlying atmosphere, warming northern Europe. Cooling in the North Atlantic increase the density of this surface water to the
