WebJan 3, 2024 · The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness. Are there currents in the deep ocean? Deep ocean currents are driven by density and temperature gradients. This thermohaline circulation is also known as the ocean’s conveyor belt. WebAs opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. 1) is that part of the ocean circulation which is driven by density differences. Sea water density depends on temperature and salinity, hence the name thermo-haline.

WebThese currents bring heat from the tropics to the polar regions; the Gulf Stream, for instance, brings warm water along the eastern coast of the US up to Northern Europe. Deep currents, also known as thermohaline circulation, result from differences in water density. These currents occur when cold, dense water at the poles sinks.

WebThermohaline 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. WebCurrents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation. These currents move water masses through the … WebDeep-ocean circulation consists mainly of thermohaline circulation.
