Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. [ 1 ] [ 2 ] The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content , factors which together determine the density of sea ...
English: Thermohaline Circulation (The Great Ocean Conveyor Belt) This animation first depicts thermohaline surface flows over surface density, and illustrates the sinking of water in the dense ocean near Iceland and Greenland. The surface of the ocean then fades away and the animation pulls back to show the global thermohaline circulation.

Animation of the thermohaline circulation. The later part of this animation shows the Antarctic Circumpolar Current. Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise (as seen from the South Pole) from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift.
The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of seawater. The thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes.
The cold blob in the North Atlantic (also called the North Atlantic warming hole [2] [3]) describes a cold temperature anomaly of ocean surface waters, affecting the Atlantic Meridional Overturning Circulation (AMOC) which is part of the thermohaline circulation, possibly related to global warming-induced melting of the Greenland ice sheet.
Due to global warming and increased glacier melt, thermohaline circulation patterns may be altered by increasing amounts of freshwater released into oceans and, therefore, changing ocean salinity. Thermohaline circulation is responsible for bringing up cold, nutrient-rich water from the depths of the ocean, a process known as upwelling. [69]
