ABSTRACT 



Thermal structure of a rectangular area approximately .140 

 kilometers on a side contiguous to the Continental Shelf north- 

 east of Cape Hatteras was investigated between 19 September 

 and 13 October 1968. iVIajor features included an area of 

 warm (>2rC) surface water inshore of the northern wall of 

 the Gulf Stream and a strong sound channel impinging upon 

 the Continental Slope. A subsurface temperature maximum 

 was observed beneath warm surface water at 70 percent of all 

 deepwater stations. Zero layer depths occurred at 56 percent 

 of relatively cold (< 19°C) water stations over the Continental 

 Shelf. These features persisted throughout the survey.
