Coastal & Marine Geology Program

Field Activity Details for field activity 1986-024-FA

Other ID: 86-Test

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Barry Irwin

Affiliate Investigator(s): John Gann, USGS-Menlo Park

Information Specialist(s): Barry Irwin

Data Type(s): Electro-Magnetic: Gravity, Location-Elevation: Navigation

Scientific Purpose/Goals: Transit from eastern Caribbean work area to western Caribbean to test new navigation equipment and run one gravity line.

Vehicle(s):

Start Date: 1986-10-22

Start Port/Location: Roosevelt Roads, Puerto Rico

End Date: 1986-10-25

End Port/Location: Kingston, Jamaica

Equipment Used: Gravity meter (wh), Magnavox satellite positioning system, GPS (wh)

Information to be Derived: Satellite navigation system test;

Summary of Activity and Data Gathered: Integration of the Atlantic Marine Geology navigation system with the gravity meter and the new STARFIX commercial satellite navigation system was completed during transit. Results acquired during 6 crossings of the same feature provided excellent results and indicated system was successful.
