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.
