Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Bradford Butman
Data Type(s): Environmental Data: CTD, Imagery: Photo, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology, Seismics: Boomer, Sonar: Sidescan, Sonar: Single Beam, Time Series: Mooring (physical oceanography)
Scientific Purpose/Goals: This cruise was part of a continuing study of currents and sediment transport on the United States East Coast Continental Shelf. Objectives were to: recover 1 tripod and 3 current moorings; deploy 4 tripods and 3 current moorings; repair/replace surface buoys; obtain grab samples at mooring locations, obtain gravity cores at selected sites; conduct temperature/salinity surveys and collect suspended matter samples for talc analyses; and conduct a sidescan survey of large-scale bedforms on Georges Bank.
