| Purpose | The purpose of this cruise was to map the entire ocean floor of the EEZ of Puerto Rico and the U.S. Virgin Islands. | ||||||||
| Location | EEZ of Puerto Rico and the U.S. Virgin Islands, United States, Caribbean Sea, North America, North Atlantic; | ||||||||
| Summary | 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. | ||||||||
| Info derived | Sea floor map; | ||||||||
| Comments | This cruise was carried out jointly by the U.S. Geological Survey (USGS) and the British Institute of Oceanographic Sciences (IOS). Personnel from the Geological survey of the Dominican Republic (DR), Puerto Rico's Department of Natural Resources (DNR) and Great Britain's Research Vessel Services (RVS) also participated. Scanlon (USGS) and Masson (IOS) shared the duties of Chief Scientist while Harris (IOS) was designated as Party Chief. Original Center People field contained: Kathy Scanlon - co-Ch. Sci.; Dann Blackwood - photographer; Chris Polloni - watchstander, Nov. 15 - Dec. 3. Project = GLORIA Survey 1985, GLORIA Survey 1985 | ||||||||
