WebOct 8, 2009 · The Thermohaline Circulation - The Great Ocean Conveyor Belt. The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These two regions don't mix except in certain special areas. The ocean currents, the movement of the ocean in the surface layer, are driven mostly by the wind. The movement of surface currents pushed by the wind is fairly intuitive. For example, the wind easily produces ripples on the surface of a pond. Thus, the deep ocean—devoid of wind—was assumed to be perfectly static by early oceanographers. However, modern instrumentation shows that current velocities in deep water masses can be significant (although much less than s… nouk and corrine acim

"WebBetween the surface and deep ocean is a sharp transition between warmer surface called the thermocline at a depth of about a few hundred meters. Although surface and deep waters are not well-mixed, they do mix gradually over hundreds of years through the movements of a global ocean current (a pattern called thermohaline circulation ).
