Other ID: 85 Leg 4; FRNL 85-4
Status: Completed
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Funding Program(s):
Principal Investigator(s): Kathryn Scanlon Catanach
Affiliate Investigator(s): Doug Masson - IOS
Information Specialist(s):
Data Type(s): Sonar: Sidescan, Seismics: Air Gun / Water Gun, Seismics: Boomer, Seismics: Bubble Gun, Seismics: Sparker, Seismics: Sub Bottom Profiler, Electro-Magnetic: Magnetics, Sonar: Single Beam, Location-Elevation: Navigation
Scientific Purpose/Goals: The purpose of this cruise was to map the entire ocean floor of the EEZ of Puerto Rico and the U.S. Virgin Islands.
Vehicle(s):
Start Port/Location: San Juan, Puerto Rico
End Port/Location: San Juan, Puerto Rico
Start Date: 1985-11-04
End Date: 1985-12-03
Equipment Used: GLORIA sidescan, Air gun, Single channel hydrophone, Marine magnetometer, 3.5 kHz, 10 kHz Bathymetry, ABC navigation system, Transit GPS, Dead reckoning
Information to be Derived: Sea floor map;
Summary of Activity and Data Gathered: The GLORIA sidescan sonar data are of excellent quality and complete coverage of the EEZ area was obtained. No down-time was experienced by GLORIA. The airgun, 10 kHz echo sounder and magnetic data are also of high quality with only a few hours of airgun data lost because of technical problems. The 3.5 kHz echo sounder records vary in quality from good to very noisy. This cruise was made scientifically successful and most enjoyable by the cooperation and competence of the ship's officers and crew and our multinational scientific staff.
