Document Summary

Below the mixed layer: the mixed layer is stopped by the thermocline, which is a temperature inversion analogous to the inversion at the top of the boundary layer in the atmosphere, a few hundred meters thick. There are two major regions on earth, where bottom water is currently produced - the north. Each contribute about 50 % to bottom water formation.
