ABSTRACT 



This report contains tlie observed and interpolated temperature and 

 salinity data plus the computed sigma-t, geopotential anomalies and sound 

 velocities for 136 oceanographic stations occupied by U.S. Coast Guard cutters 

 at Ocean Station DELTA (centered at 44°00 N., -il^OO' W.) during July 

 1966-August 1967. They were the USCGC ESCANABA (AVHEC 64), 15
