PAC_EXT - Extracted seabed data for the continental margin of the U.S. Pacific Coast (California, Oregon, Washington) from usSEABED (pac_ext.txt)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 16, 2025 | Last Modified: 20230516
This data layer (PAC_EXT.txt) is one of five point coverages of known sediment samples, inspections, and probes from the usSEABED data collection for the U.S. Pacific continental margin integrated using the software system dbSEABED. This data layer represents the extracted (EXT) output of the dbSEABED mining software and contains data items which were extracted from the data resources files and generally represent lab-based analytical data. The EXT data are usually considered the most rigorous data available, although some data may represent a subsample of the sediment (that is, large shells or stones may have been excluded from the analysis). This file contains the same data fields as the parsed (PAC_PRS) and calculated (PAC_CLC) data files, and the three files may be combined.
