ASSTRACT 
Thermal structure of a rectangular area, approximateiy 220 kilo- 
meters on a side and contiguous to the Continental Shelf northeast of 
Cape Hatteras was investigated by aircraft between 9 October 1968 and 
16 May 1969 with the object of formulating an analysis and prediction 
model. Majer features in the area included warm water northwest of 
the Guif Stream, entrainment of Shelf Water into the Guif Stream cvstem, 
lateral displacement of the northern edge of the Gulf Stream, and a 
thermal gradient adjacent to the Continental Slope during winter. A 
simplified model of thermal structure describes interaction of observed 
water masses.
