Data Type(s): Imagery: Video, Sampling: Geology, Seismics: Sparker, Environmental Data: Temperature, Sampling: Chemistry, Location-Elevation: Navigation
Scientific Purpose/Goals: 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.
