Digital Mosaics of the GLORIA Sidescan Sonar Data of the Gulf of Mexico

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: August 08, 2025 | Last Modified: 20250805
In the late summer and fall of 1985, the USGS conducted surveys of the Exclusive Economic Zone (EEZ) in the Gulf of Mexico. The collected GLORIA data was processed and digitally mosaicked to produce continuous imagery of the seafloor (EEZ-Scan, 1985). A total of 16 digital mosaics of a 2degree by 2degree (or smaller) area with a 50 meter pixel resolution were completed for the Gulf of Mexico. Those individual mosaics were later combined to produce two overviews (east and west) of the Gulf of Mexico at a 250 meter pixel resolution.
