    • BS_250M_LCC_NAD27.TIF - Bering Sea U.S. EEZ GLORIA sidescan-sonar composite mosaic (LCC, 250 m, Clarke1866)

    Metadata Updated: September 17, 2025

    From 1986 through 1989, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted several surveys within the U.S. EEZ off Alaska. Four surveys during that time period focused on the Bering Sea region. 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. The results of these surveys were 30 digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution.
