    The GLORIA data for the Cayman Trough region were acquired during a single cruise aboard the R/V FARNELLA (1985-037-FA) conducted from October 22 to November 2, 1985. The cruise objective was to insonify the central region of the Cayman Trough. As a result of this survey, two digital mosaics of a 2-degree by 2-degree area were completed (Cruise Report HMS FARNELLA Leg 3B, 1985; EEZ-SCAN 85 Scientific Staff, 1987).

    The GLORIA image of the Cayman Trough area covers approximately 51,508 sq km of seafloor.
