Description:

Abstract:

The Gulf of Alaska U.S. EEZ GLORIA digital sidescan-sonar mosaic covers about 806,000 square kilometers (sq km) of sea-floor. The mosaic shows the sea-floor morphology from Uminak Pass to Dixon Entrance, from the shelf break seaward to about 400 km. An additional 70-km-wide swath was imaged along the British Columbia margin to follow the trace of the Queen Charlotte Fault south of the Dixon Entrance. Major features visible on the mosaic include continental-margin deformation structures and submarine-channel systems. 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 30 digital mosaics with a 50-meter pixel resolution were assembled to complete the Gulf of Alaska overview mosaic.

Purpose:

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

An empty PCI database for the full extent of the Gulf of Alaska U.S. EEZ GLORIA was defined. The imagery database was defined with an Lambert Conic Conformal (LCC) Conic projection at a resolution of 250-meters.

Process_Step:

Process_Description:

Using the PCI Geomatics tool GCPworks, the 30 individual 50-meter mosaics were combined to create a composite overview of the Gulf of Alaska U.S. EEZ GLORIA data at a resolution of 250-meters. 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 Gulf of Alaska. 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.

Process_Step:

Process_Description:

Edits to the metadata were made to fix any errors that MP v 2.9.46 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added a landing page link as the first link in the identification section. Fixed the date format in the time period of content. Removed LIDAR bounding coordinates - an artifact of Esri and MP processing. Attempted to modify http to https where appropriate. Added a cross-reference online link. The source information was incomplete and had to be modified to meet the standard. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.

Entity_and_Attribute_Overview:

There are no attributes associated with a GeoTIFF image. Image pixel values contain acoustic reflectivity values normalized to an 8-bit data range (0-255). Low-backscatter is represented by dark tones (low values) and high-backscatter is represented by bright tones (high values). These data have NOT been radiometrically enhanced.
