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. 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. Purpose: This remote sensing image of the sea-floor is a reduced-resolution (250-meter) composite mosaic of the 16 mosaics created from the Gulf of Mexico GLORIA sidescan-sonar data.

The imagery database was defined with an Albers Equal Area (AEA) Conic projection at a resolution of 250-meters. Standard parallels of 29.5 and 45.5 and a central longitude of -88 were selected with a Clarke 1866 spheroid.

The individual full-resolution GLORIA mosaics with the white flood-filled background were mosaiced together to create a single reduced-resolution composite mosaic for the Gulf of Mexico. Individual mosaics were "dropped" into the composite database. No rubber sheeting or geometric corrections were applied to the mosaics. However, some mosaics were radiometrically enhanced to reduce the effect of the individual square boundaries and produce a more uniform overview. The individual 16 mosaics were combined using a nearest-neighbor resampling mode.
