Other ID: P-2-85
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Location: U.S. Virgin Islands, Puerto Rico, United States, Caribbean Sea, North America, North Atlantic;
Principal Investigator(s): N. Terence Edgar
Affiliate Investigator(s): Juan Trias
Data Type(s): Location-Elevation: Navigation, Seismics: Air Gun / Water Gun
Scientific Purpose/Goals: Collect high-resolution single-channel seismic reflection data near Puerto Rico and the U.S. Virgin Islands. This endeavor was secondary to the collection of gravity data by the USGS-Menlo Park personnel for the Defense Mapping Agency (DMA). This report covers the seismic reflection aspects of the cruise.
