Other ID: 82FARN-7; FARN 82-7

Status: Completed

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

Funding Program(s):

Location: continental slope, northern Gulf of Mexico, United States, North America, North Atlantic;

Principal Investigator(s): Louis E. Garrison

Affiliate Investigator(s): Neil Kenyon - IOS

Information Specialist(s):

Data Type(s): Environmental Data: Temperature, Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Sonar: Sidescan, Sonar: Single Beam

Scientific Purpose/Goals: Survey the continental slope in the northern Gulf of Mexico with the GLORIA long-range sidescan-sonar, a cooperative study with the Institute of Oceanographic Sciences, Godalming, England.

Vehicle(s):

Start Date: 1982-02-02

Start Port/Location: New Orleans, LA

End Date: 1982-02-24

End Port/Location: Miami, FL

Equipment Used: GLORIA sidescan, Air gun, 10 kHz Bathymetry, XBT, Northstar 6000 LORAN-C, Magnavox satellite positioning system, Single channel hydrophone

Information to be Derived: Sea floor map; Bathymetric maps;

Summary of Activity and Data Gathered: The cruise collected 3,731 nautical miles of data on the continental slope in 17 days for the USGS, and in 2 additional days collected 395 nautical miles (732 km) of sidescan, 10 kHz echo sounder and large airgun data for an IPOD site survey on Mississippi Fan. The IPOD data will be deposited in the IPOD data bank when processing is completed. GLORIA sidescan sonar: 6910 km (12 reels of 9-track digital magnetic tapes, 12 reels of analog magnetic tapes, 464 photo negatives, photo prints, speed rectified sidescan data, shipboard monitor records); 10 kHz echo sounder: 6910 km (2 sec. sweep shipboard records, 0.5 sec. sweep shipboard records); Airgun: 6910 km (59 reels of analog magnetic tape, shipboard monitor records); Navigation: 50 Northstar cassette recordings from bridge, 19 magnetic tapes from seismic lab, 8 rolls printout from bridge, 4 rolls printout from seis lab, 1 reel digital 9-track tape of LORAN-C plus satellite fixes with water depths; XBT records: 69.
