moves seaward was found. Oxygen and chlo- 

 rophyll concentrations were relatively high 

 within this bubble suggesting increased photo- 

 synthetic activity. 



In general, surface salinity increased grad- 

 ually from the shore to the shelf edge. Layers 

 of high salinity water were found in the slope 

 water off the Mid-Atlantic Bight in September 

 and December. Upweiling of this high salinity 

 layer appears to have been caused by a local 

 cyclonic eddy in September. 



A counterflow inshore of the Gulf Stream 

 was inferred from the slope water density. 

 This flow may have been discontinuous in the 

 upper 500 meters and may have reversed 

 direction.
