Thermohaline Circulation - Global Ocean Conveyor System

The last major glacial climate began about 27,000 years ago and reached its peak about 20,000 to 18,000 years ago. At that time, glaciers of several kilometers in thickness, covered large areas of Europe and North America, reaching as far south as New York and the Ohio River Valley.

What is the global ocean conveyor belt?

 · The ocean is not a still body of water. There is constant motion in the ocean in the form of a global ocean conveyor belt. This motion is caused by a combination of thermohaline currents (thermo = temperature; haline = salinity) in the deep ocean and wind-driven currents on the surface.
