change is relatively slight, and the circulation structure described under 

 paragraph A, above, is clearly evident. 



VTI. CONCLUSIONS 



A preliminary examination of the data shows that internal waves 

 play a large part in the fluctuation of thermal structure in this area. 

 The data will be carefully analyzed to determine whether the modes of 

 oscillation of the internal waves are simple. If they are, the pre- 

 diction of thermal structure with reasonable accuracy can be simplified. 



A research vessel, instrumented especially for ASWEPS requirements, 

 would allow for the continuation of experiments of this nature.
