Thermohaline circulation. 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 ...
AMOC in relation to the global thermohaline circulation . The Atlantic meridional overturning circulation (AMOC) is the main current system in the Atlantic Ocean [1]: 2238 and is also part of the global thermohaline circulation, which connects the world's oceans with a single "conveyor belt" of continuous water exchange. [18]
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.

Thermohaline circulation (properly described as meridional overturning circulation) of the world's oceans involves the flow of warm surface waters from the southern hemisphere into the North Atlantic. Water flowing northward becomes modified through evaporation and mixing with other water masses, leading to increased salinity.
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.
Winds drive ocean currents in the upper 100 meters of the ocean's surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.
The Thermohaline Circulation is part of the global ocean circulation. Although this phenomenon is not fully understood yet, it is known that its driving processes are thermohaline forcing and turbulent mixing. [26]
