Dear Mr. Pyle: 
Enclosed are BT cards for cruises 14994, REXBURG, and 14995, 
MARYSVILLE, together with IBM listing of the data, template and explanation 
sheet to assist you in interpreting the listing. You may retain the templet 
and explanation sheet to be used with future listings. 
I am sorry for the delay In forwarding these BT cards to you 
but over the past few months we have been debugging our new digitizer and 
the computer programs associated with it. There have been some unavoidable 
delays In completing the data processing. 
We had considerable difficulty in determining a temperature 
correction for the data taken on the MARYSVILLE. The relationship between 
the injection reference temperatures and BT readings was so erratic that it 
was almost impossible to make any sense out of them. However, by making a 
comparison with the deep temperatures on the REXBURG cruise and temperatures 
at 150 and BOO meters in the GALCOFI data In the same area, we finally 
concluded that a -3.2°F correction would be the most reasonable. With this 
correction, the surface temperature distribution agrees also with the BCF 
temperatures for the same period in that area. Also, the existence of a cold 
tongue extending southwest from Pt. Conception appears in both of these 
distributions . 
I hope this explanation will assist you in interpreting the data. 
Sincerely yours
