Abstract 



Observed and interpolated temperature and salinity data, plus com- 

 puted sigma-t values, geopotential anomalies and sound velocities, are 

 presented for 315 oceanographic stations occupied by U.S. Coast Guard 

 cutters at Ocean Station ECHO (centered at 35° OO'N, 48° OO'W) during 

 November 1967-December 1968. Profiles of temperature versus depth and 

 salinity versus depth, as well as a plot of temperature versus salinity are 

 presented for each of the 14 patrols. Plots of temperature versus time and 

 salinity versus time at selected depths are presented and analyzed to 

 describe annual temperature and salinity cycles at ECHO. The presence 

 of Mediterranean water at intermediate depths, and a series of temperature 

 and salinity cycles with periods of 2 to 3 months at depths between 200 and 

 700 m are noted.
