Summary of Activity and Data Gathered: Too rough to recover Grassle's tripod GBQ; 2 surface buoys at K left for recovery during Jan. 1981 cruise (OCNS 091, FA 81002). Moorings deployed: 12 (#205, 207, 208, 209, 211, 214, 215, 216, 217, 218, 219, and 220 all recovered FA 81009 OCEANUS 95 Apr. 23 - May 6, 1981). Moorings recovered: 2 (#195 and 196 partial, deployed FA 80009 OCEANUS 81 May 23 - Jun. 1, 1980). XBT stations: 37; Surface salinity: 35; Bathmetry surveys at mooring stations: 5; Hydrographic stations: 38.
