    • GMX_Q15.TIF - U.S. Gulf of Mexico EEZ GLORIA sidescan-sonar data mosaic (15 of 16) (ACEA, 50 m, Clarke1866)

    Metadata Updated: November 27, 2025

    During February 1982 and again from August 7 to October 22, 1985 the U.S. Geological Survey (USGS) conducted four cruises to cover the U.S. Gulf of Mexico Continental Margin Exclusive Economic Zone (EEZ) seaward of the continental shelf edge. 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 seafloor. A total of 16 digital mosaics of a 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the Gulf of Mexico region.
