CYM_250M_MER_NAD27.TIF - Cayman Trough GLORIA sidescan-sonar composite mosaic (MER, 250 m, Clarke 1866)
From October 22 to November 22, 1985 the U.S. Geological Survey (USGS) conducted a single to survey to ensonify the Cayman Trough. The survey took place over the coastal region of the spreading ridge and along one line to the eastern extremity of the Trough. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the sea-floor. Two digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution were completed for the Cayman Trough south of the Cayman Islands.
