Description	In 1984, the U.S. Geological Survey (USGS), Coastal and Marine Geology Program (CMGP), began a program to map the areas of the U.S. Exclusive Economic Zone (EEZ). To accomplish the mapping of the deepwater portion (depths greater than 400m) of the EEZ, the USGS selected the long-range sidescan sonar system GLORIA (Geological LOng-Range Inclined Asdic). GLORIA creates images that are a record of the acoustic backscatter from the ocean floor and was developed specifically to map the morphology and texture of seafloor features in the deep ocean. The GLORIA imagery provides a broad-scale view of sea-floor features and the effects of sedimentary processes that had been previously unknown.
