Mixed layer depths are based on a temperature increase of 0.1 and 0.5
degrees C from the second temperature value listed in the CTD files, which
corresponds roughly to a density increase of 0.03 and 0.125 density units.

The second TEMPERATURE value was used because there occasionally appeared to
be questionable numbers as the first value.  The temperature change of 0.1
degree C was recommended by Dr. Craig Lee (WHOI) after looking at the data
and the 0.5 degree C value is the Levitus standard used in his NOAA global
atlases.  These are also the values used in the US JGOFS EqPac program.

Please note variable initial (starting) depths.

Calculations were made by Jan Gundersen. (TAMU).
