Ocean Circulation

Ocean Circulation. Chapter 9. Geostrophic Currents. As water moves it is constantly deflected by the Coriolis Effect This effect pushes water into a hill in the center of the gyre. It is about 1 meter high in the center of the Atlantic Nevertheless, it IS a hill, and water runs downhill.

Abyssal Circulation

Abyssal Circulation. Deep ocean is below the permanent thermocline (at 1~km) with ? ~2 o - 4 o C below 2 km (0 o -2 o C at 4 km typically). Waters of such low temperatures can only be formed by cooling in Polar Regions.
