Information to be Derived: Suspended sediment concentrations; Sea floor map; Morphology;

Summary of Activity and Data Gathered: Operated only in daylight. Due to high winds and resultant seas, high-resolution data quality is poor to fair; sidescan sonar data is fair. Sidescan sonar: 26 km, fair quality; Uniboom: 50 km, poor to fair quality; TV Tape: 6 hours; Grab samples: 25; SARIMA Time Log #68.
