Dates: February 03, 1980 to February 10, 1980
Chief scientist: Kurt Grove
Bill Cleary, Chief Scientist - Duke University
Objectives: 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.
Type of Activity: Sampling; Seismic profiling; BathymetryBathymetry
Information to be derived: Seismic and airgun records
Summary: 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.
