Summary of Activity and Data Gathered: The 2 tripods and 1 current mooring which we were unable to recover on OCEANUS were recovered in January 1980 with the Tug WHITEFOOT (FA 80001). The release receiver batteries were defective and we could not communicate with the releases. 1 VACM was lost. Because of extensive grappling/search operations we did not have time to recover 1 buoy with current meter at Station B. Christmas and ship deadlines precluded another few hours of shiptime. We elected to deploy the new equipment and recover the instrument later. On return to site in January, the buoy was missing. Deployed tripods: 5 (#183, 184, 185, 186, and 187 all recovered FA 80009 OCEANUS 81 May 23 - Jun. 1, 1980). Deployed current meters: 4 (#188, no recovery information, fishing boat netted buoys and camera Mar. 25, 1980; 189, 190, and 192 all recovered FA 80009 OCEANUS 81 May 23 - Jun. 1, 1980). Recovered tripods: 2 (#176 and 179). Recovered current meters: 2 (#181 and 182). CTDs: 10; XBTs: 49; Surface salinity samples: 57.
