Other ID: 87-1

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): Bradford Butman

Affiliate Investigator(s):

Information Specialist(s):

Data Type(s): Sonar: Sidescan, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Recover 3 tripod systems deployed in western Massachusetts Bay and conduct sidescan sonar surveys at each mooring location to define the local topography and bottom roughness.


Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 1987-04-08

End Date: 1987-04-10

Equipment Used: Klein 531 sidescan, Bottom platform

Information to be Derived:

Summary of Activity and Data Gathered: Instrumentation recovered from Feb. 7 OCEANUS cruise. All three tripods recovered unfouled, but time lapse cameras malfunctioned. Data from (2) 100 kHz sidescan sonar systems are very poor with only 0.50 km horizontal range and 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 (#320) deployed at Station A in February was found adrift in Boston Harbor March 4. Current meter and float were recovered, but release was lost. Moorings recovered: 3 (#317, 318, and 319, deployed FA 87005 OCEANUS Feb. 7, 1987).
