Field Activity Details for field activity 1976-041-FA

Other ID: FAY 026

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): PARTNER

Information Specialist(s):

Data Type(s): Sampling: Geology, Location-Elevation: Navigation

Scientific Purpose/Goals: Obtain 10 vibracores each in both the northern and southern areas of high leasing interest. Emplace 3 reference pipes with buoys and pingers. Obtain 10 hydrostatically damped gravity cores, 5 in each area of interest. Run 3 sidescan sonar lines 20 miles long, 700 m apart in each area.

Vehicle(s):

Start Date: 1976-10-16

Start Port/Location: Woods Hole, MA

End Date: 1976-10-25

End Port/Location: Charleston, SC

Equipment Used: Alpine Vibracorer, Corer - piston, Sidescan sonar, Loran-C

Information to be Derived: Samples and chemical analysis; Grain size analysis; Sea floor map; Morphology;

Summary of Activity and Data Gathered: All cruise objectives were attained. The only major shortcoming was the inability to maintain planned sonar transects when in the Gulf Stream. Vibracores were curated at Skidaway. Hydrostatically damped cores were curated at USGS-Woods Hole. Sidescan sonar data was curated at Georgia U. Vibracores: 18 cores, 2 to 19 feet long, 3 with rock in base, 7 interpreted as bottoming out in rock substrate; custodian = Skidaway. Grab sample: 1; custodian = Skidaway. Hydro-damped cores: 16 cores, 3 to 12.75 in. long; custodian = Mike Bothner, USGS-Woods Hole. Sidescan sonar: 108 km; custodian = Georgia U.
