Summary of Activity and Data Gathered: Tripod #116 was dragged 4 miles and damaged approximately 6 days after deployment; however, some good data were obtained. See cruise report for full description. Deployed: 1 current meter (#118 recovered FA 77023 OCEANUS 29 July 6-13, 1977); Deployed: 2 tripods (#119 and 120 both recovered FA 77009 WHITEFOOT March 8 - Apr. 17, 1977); Recovered: 1 current meter (#115 deployed FA 76031 OCEANUS 13 Aug. 12-24, 1976); Recovered: 2 tripods (#116 and 117 both deployed FA 76044 WHITEFOOT Oct. 26-31, 1976); XBT profiles: 83; Transmissometer profiles: 22; Water samples (salinity): 95; Water samples (suspended matter): 65.
