ABSTRACT 

 A research experiment, conducted aboard the USS SAN 

 PABLO for the purpose of studying temperature structure 

 in the waters of the Tongue of the Ocean from 4 to 20 March 

 1960, is described. The data have been tabulated and listed 

 as Appendixes to the report. Analysis of the data has not 

 been completed; however, a preliminary examination shows 

 that internal waves play a large part in the fluctuation of 

 thermal structure in this area.
