Thermohaline Ocean Circulation #1- What is The Thermohaline Ocean Circulation concept? The Thermohaline Ocean Circulation is when the circulation of the ocean is caused by heat and freshwater in the sea’s surface. This causes the mixing of heat and salt in the ocean. Thermo is temperature and haline is salt. Temperature and salt are the two factors that determine the sea’s density. The circulation causes differences in seawater density. The circulation also causes warm water from the southern hemisphere

If the Gulf stream was to slow down considerably (as it has in the past)‚ then winters in Europe would become very cold. The last time this happened
