Alternate Leg: ID (87-1) Area of Operations : Massachusetts Bay, Massachusetts, United States, North America, North Atlantic Dates: April 8, 1987 to April 10, 1987 Chief scientist: Brad Butman
Objectives: Recover 3 tripod systems deployed in Western Massachusetts Bay and conduct side-scan sonar surveys at each mooring location to define the local topography and bottom roughness. Type of Activity: Equipment recovery, sonar surveying Information to be derived: Equipment recovery and side-scan sonar survey. Summary: Instrumentation recovered from Feb. 7, OCEANUS cruise. All three tripods recovered unfouled, but time lapse cameras malfunctioned. Data from 2 100 kHz sidescan sonar very poor, only .50km collected w/poor resolution. Lab testing of system is required. Short, hand-deployed cables did not allow fish to be flown close enough to the bottom. Subsurface mooring deployed at Station A in February found. Current meter and float recovered, but release was lost. USGS Project Number:
