Abstract 



This report contains the observed and interpolated temperature 

 and salinity data plus the computed sigma-t, geopotential an- 

 omalies, and sound velocities for 89 oceanographic stations oc- 

 cupied by four U.S. Coast Guard cutters at ocean station ECHO 

 (centered at 35° N., 48° W.) during September 1966-October 

 1967 They were the USCGC YAKUTAT (WHEC 380), 21 

 September-13 October 1966; USCGC MCCULLOCH (WHEC 

 386), 4-25 February 1967; USCGC ANDROSCOGGIN (WHEC 

 68), 1-20 June 1967; USCGC ABSECON (WHEC 374), 17 

 July-6 August 1967; USCGC MCCULLOCH, 27 September-13 

 October 1967. Casts of 14 Nansen bottles were made daily to 

 1500 meters where weather and operating conditions permitted. 

 In addition, sampling was successfully extended to near the 

 bottom at one station during each patrol.
