Abstract
An example of off-shore three-dimensional seismic survey is reported. The survey was provided on the Barbados accretionary prism where the Atlantic plate subducts beneath the eastern margin of the Caribbean plate. R/V Maurice Ewing of LDGO was used for the survey. Study area locates far form the Barbados Island, approximately 300 km. To take the real-time absolute location of the ship, differential GPS technique was successfully adopted for this survey and completed. Other quality control techniques are also provided for this survey. Three-dimensional seismic survey has great advantages for the earth sciences, and should be commonly provided in the near future.
