The Thermohaline Circulation - The Great Ocean Conveyor Belt

The Thermohaline Circulation - The Great Ocean Conveyor Belt
Primary Topic: 
Water Cycle
Subtopics: 
Water Properties, Earth Systems, Energy Cycle
Type: 
Video
Audience: 
Informal, Formal, 9 - 12, 6 - 8
Standards: 
ESS2.C
Keywords: 
ocean, density, salinity, ocean temperature, ocean circulation, thermohaline, ocean currents
Summary: 
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, which creates a large slow current called the thermohaline circulation.
