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 23 digital mosaics of a 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the U.S. Atlantic Continental Margin. Purpose: This remote sensing image of the sea-floor is a reduced-resolution (250-meter) composite mosaic of the 23 mosaics created from the U.S. Atlantic East coast GLORIA sidescan-sonar data. Supplemental_Information: Two of the mosaics contained in this composite mosaic have not been previously released. These mosaics, numbers 22 and 23, were obtained outside of the U.S. Exclusive Economic Zone and were not included in the original publications or data releases. They complete a southern extension of the original released mosaic and are located north of the Bahamas.

Process_Step: Process_Description: An empty PCI database for the full extent of the U.S. Atlantic East Coast GLORIA was defined. The imagery database was defined with an Albers Equal Area (AEA) Conic projection at a resolution of 250-meters. Standard parallels of 29.5 and 45.5 and a central longitude of -73 were selected with a Clarke 1866 spheroid (NAD27).

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. Atlantic East Coast. 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 23 mosaics were combined using a bi-linear resampling mode to reduce noise and blockiness.
