Other ID: 85-3

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Location: La Romana to Isla Saona, southeastern Dominican Republic, Caribbean Sea, North America, North Atlantic;

Principal Investigator(s): N. Terence Edgar, Rafael W. Rodriguez

Affiliate Investigator(s):

Information Specialist(s): PARTNER

Data Type(s): Sampling: Biology, Sampling: Chemistry, Sampling: Geology, Seismics: Sparker, Location-Elevation: Navigation

Scientific Purpose/Goals: Evaluate a sand deposit off Isla Saona as a potential economic resource of the Dominican Republic.


Start Date: 1985-09-20

Start Port/Location: San Juan, Puerto Rico

End Date: 1985-10-02

End Port/Location: San Juan, Puerto Rico

Equipment Used: SCUBA, Alpine Vibracorer, Sparker system, Raytheon radar

Information to be Derived: Grain size analysis; Sea floor map;

Summary of Activity and Data Gathered: This was the third cruise to the Dominican Republic as part of a five-year agreement between the USGS and DGM. This year's cruise, at the request of DGM, examined a sand body extending about 2 km northwest of Isla Saona. The sand body could eventually be exploited to be used as aggregate in the construction industry. The overall sedimentary environments and the geologic characteristic of the shoal were evaluated. Surface sediment samples: 15; Beach samples: 10; Vibracore samples: 6.
