Field Activity 1975-015-FA

Identifier 1975-015-FA
Purpose The cruise objective was to recover a single mooring on the southern slope of Georges Bank and redeploy 2 moorings at the same site.
Location southern slope of Georges Bank, United States, North America, North Atlantic;
Summary The surface element of the U-shaped mooring had been found to be missing in June, which required that ground line grappling be the primary recovery method. Arriving on station, we proceeded to make several passes over the mooring with grappling gear. The dragging operation proved unsuccessful and the decision was made to re-evaluate the mooring design prior to redeployment. Ship track: 410 nm (228 km); Moorings recovered: 0; Moorings deployed: 0.
