Other ID: 80-3; E-10-80
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Kurt Grove
Affiliate Investigator(s): Bill Cleary, Chief Scientist - Duke University
Data Type(s): Sampling: Geology, Location-Elevation: Navigation
Scientific Purpose/Goals: Acquire seismic, bathymetric, and sedimentologic data from previously unsampled portion of the Puerto Rico insular shelf and slope north of Culebra Island and provide alternate research goals for the ill-fated Puerto Rico Trench cruise of the R/V EASTWARD E-1b and c-80.
Start Date: 1980-02-03
End Date: 1980-02-10
Equipment Used: Grab sampler - Shipek, Magnavox satellite positioning system, Loran-C
Information to be Derived:
Summary of Activity and Data Gathered: Retrieved 62 bucket and shipek grab sediment samples from the insular shelf north of Culebra and south southwest of St. Thomas; 42 short gravity cores from slope areas north of Culebra and south of St. Thomas; 900 nautical miles of 3.5 kHz seismic record of the slope and shelf; 317 nautical miles of the 20 cu. in. airgun record in the slope north of Culebra; and 41 nautical miles of 20 cu in. airgun record on the slope south west of St. Thomas. All airgun data is recorded on magnetic tape. Data will be jointly worked up by Bill Cleary, Orrin Pilkey, and USGS-San Juan personnel.
