Keeping Current. While ocean currents are shallow-level circulations, there is global circulation which extends to the depths of the sea called the Great Ocean Conveyor. Also called the thermohaline circulation, it is driven by differences in the density of the sea water which is controlled by temperature (thermal) and salinity (haline).

The Global Conveyor Belt serves as a model for the mechanism of how heat is transported throughout the ocean. Global thermohaline circulation is a relatively slow process. Radiocarbon measurements show that deep water in the ocean is replaced by new bottom water only every 600 years. Although slow, global thermohaline circulation is important ...

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 water.

Ocean temperature plays a key role in the conveyor belt, so a change in the Earth's climate might have drastic effects on the system. If one part of the conveyor belt breaks down—if cold water is not lifted to the surface in upwelling, for instance—nutrients will not be distributed to start the food chain. Organisms, such as phytoplankton,
