Change in Heat Content
For 2001 cruises – heat content in upper waters was
negative and in deeper waters was positive
Indicates a net heat loss from surface
Heat source in bottom waters – CDW
Difference between two cruises was negative over
   entire water column (-0.000342 J/m3/day)  - mostly from
surface cooling
Little difference in bottom water heat content between
two cruises – suggests continual input of warm water
