AA_Q01.TIF - Aleutian Arc U.S. EEZ GLORIA sidescan-sonar data mosaic (1 of 31) (LCC, 50 m, WGS84)

During late July through September 1987 and June and July 1988 the U.S. Geological Survey (USGS) conducted four cruises to cover the U.S. Exclusive Economic Zone (EEZ) region of the Aleutian Arc. 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 31 digital mosaics of a 3 degree by 3 degree (or smaller) area with a 50-meter pixel resolution were completed for the region.
