Area of Operations: mid-Atlantic Bight, continental shelf, New Jersey, United States, North America, North Atlantic

Dates: December 10, 1975 to December 12, 1975

Objectives: 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.

Type of Activity: Mooring work

Information to be derived: Time series data

Summary: 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).
