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. Purpose: This remote sensing image of the sea-floor is a reduced-resolution (250-meter) composite mosaic of the 30 mosaics created from the Bering Sea U.S. EEZ GLORIA sidescan-sonar data.

The imagery database was defined with a Lambert Conformal Conic (LCC) projection at a resolution of 250-meters. Standard parallels of 59 and 50 and a central longitude of -177 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 U.S. Bering Sea. 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 image. The individual 30 mosaics were combined using a bi-linear resampling mode to reduce noise and blockiness.
