Other ID: AII 103
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Bradford Butman
Data Type(s): Environmental Data: CTD, Environmental Data: Temperature, Imagery: Photo, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Sonar: Single Beam, Time Series: Mooring (physical oceanography), Sonar: Sidescan
Scientific Purpose/Goals: 1. Deploy 5 tripod systems, 6 current moorings; recover 2 tripods and 2 current moorings. Monitor near-bottom circulation along the southern flank of Georges Bank through Great South Channel, and investigate coherence of flow between Georges Bank and the mid-Atlantic shelf. Study currents and sediment movement in the region of fine-grained sediments south of Martha's Vineyard. 2. Conduct temperature, salinity and suspended matter observations along shelf sections to determine position of moorings relative to coastal water masses to aid data interpretation. 3. Conduct sidescan sonar surveys to determine large-scale bedform distribution and direction of movement. 4. Recover, relight and replace necessary surface marker floats at tripod and current locations (so fishermen can avoid fouling their nets and leave instrumentation undisturbed).
