Information to be Derived: Sea floor map; Morphology; Samples and chemical analysis;

Summary of Activity and Data Gathered: Camera was lost on the first cast due to a break in the wire on the drum. 30,000 J Sparker data: 1520 km; 3.5 kHz ORE data: 1750 km; Cores: 10 (avg. 2.5 m); Dredges: 3; Minisparker data: 1520 km.
