Science: Investigating Climatic and Environmental Processes
Driven by the sun's heat absorbed by tropical oceans and impacted by variations in salt content in the water, the Thermohaline Circulation or THC is a powerful force on the world's climate system. As heat from the tropics is carried by the Gulf Stream into the North Atlantic where it is vented into the atmosphere, a deep convection of ocean waters is caused by surface cooling, with the flow of water then sinking to depths and then upwelling back to the surface at lower latitudes.
frozen, water releases salt, and thus when it melts it is salt-free. This
factor and the heavier density of salty water is particularly important
in polar regions where the convergence of fresh and saline waters influences
