Other ID: P-3-85
Status: Completed
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Funding Program(s):
Principal Investigator(s): Kathryn Scanlon Catanach
Affiliate Investigator(s): Nelson Espinell, USGS-San Juan, Puerto Rico
Information Specialist(s):
Data Type(s): Electro-Magnetic: Gravity, Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Seismics: Boomer
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.
Vehicle(s):
Start Port/Location: Roosevelt Roads, Puerto Rico
End Port/Location: Roosevelt Roads, Puerto Rico
Start Date: 1985-03-14
End Date: 1985-03-28
Equipment Used: EG&G 234, Magnavox System 5000 integrated navigation system, Single channel hydrophone, Gravity meter (wh), Air gun
