Summary for Field Activity Number 1978-022-FA

Alternate Leg ID: 78-3

Area of Operations: Southeast Georgia Embayment, Georgia Bight, United States, North America, North Atlantic

Dates: August 15, 1978 to August 19, 1978

Objectives: Study reefs and hardgrounds of the Georgia Bight to ground truth the seismic and sidescan sonar data; investigate firsthand the geologic origin and nature of the reefal features and their use as a marine habitat. Inspect bottom tripod instrument package on the shelf edge for scour, bottom conditions and composition, and document the extent of use of tripods as animal habitat. A minisparker line was planned to supplement existing data from the FAY 1975-1976 cruises and XBT observations are to be made to better define water masses associated with the tripods.
