Other ID: none
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Bradford Butman, David W. Folger
Data Type(s): Visual Identification: Ground Truthing, Imagery: Photo, Time Series: Mooring (physical oceanography), Sampling: Geology
Scientific Purpose/Goals: The objective of the ATLANTIC TWIN cruise was to deploy three bottom instrument packages (#104, 105, and 106) on the mid-Atlantic continental shelf to study the frequency, rate and processes of bottom sediment transport.
Start Port/Location: Pt. Pleasant, NJ
End Port/Location: Pt. Pleasant, NJ
Start Date: 1975-12-10
End Date: 1975-12-12
Equipment Used: Mooring tripod, Sediment traps, Current, Benthos model 372 camera and strobe
Information to be Derived: Time series data;
Summary of Activity and Data Gathered: The instrument packages consisted of a 35 mm camera and strobe (Benthos), current meter (EG&G 102), three sediment traps, acoustic release (AMF) and rope canister mounted on a tripod frame. To mark the deployment site and to reduce fishing hazards a lighted surface buoy was deployed near the tripod at two sites. Working days: 2; Ship track: 270 nm (478 km). Tripods deployed: 3 (#104 CINDY, #105 DEBBIE both recovered FA 76003 WHITEFOOT Feb. 21-27, 1976; #106 JERRY recovered FA 76001 SASSAFRAS Jan. 14-17, 1976).
