Document Summary

As depth increases, salinity increases, temperature decreases, density increases. End member waters (4)- produce water of intermediate salinity- mixing lines. Water masses- deepwater consists of limited number of end member water masses. These masses have properties of surface water until they are mixed. Antarctic intermediate waters (aaiw)- sinking waters in the antarctic ocean. These two waters form a stable water column because less dense water is above denser water. **north atlantic deep water (nadw)- deep, sinking water in the north atlantic ocean. Antarctic bottom water (aabw)- deepest water, hugs the bottom. Principal region in the world ocean where deep water ocean is produced.

Water cools and sinks- deep water formed. Great ocean conveyor belt: warm, salty water from tropics carried to north atlantic deep water. The north pacific does not produce deep water because it is not salty enough.
