Colored Shaded-Relief Bathymetry, Acoustic Backscatter, and Selected Perspective Views of the Inner Continental Borderland, Southern California

By Peter Dartnell, Neal W. Driscoll, Danny Brothers, James E. Conrad, Jared Kluesner, Graham Kent, and Brian Andrews

Data Catalog

This data catalog contains the multibeam bathymetry and acoustic-backscatter data that comprises the Colored Shaded Relief Bathymetry and Acoustic Backscatter maps of the Inner Continental Borderland, Southern California. This catalog includes data collected in 2013 by Scripps Institution of Oceanography (SIO)(MV-1316) and processed by the U.S. Geological Survey, Pacific Coastal and Marine Science Center. The bathymetry data were merged with publically available multibeam-bathymetry data acquired by federal and local agencies, academic institutions, and private firms (see below for data sources). Also available is a regional perspective view of the inner continental borderland created using the bathymetry data in this report.

The tables below provide the recently collected bathymetry and acoustic-backscatter data in several formats as well as the merged bathymetry of the inner continental borderland. To view an overview map, click on the "Quick View" links. Bathymetry data are available in ASCIIRaster format files and shaded-relief bathymetry geoTIFF images. Acoustic-backscatter images are available as geoTIFF images.

NOTE THAT THE USGS IS PROVIDING THE BATHYMETRIC DATA FOR SCIENTIFIC PURPOSES ONLY. THE USGS DOES NOT GUARANTEE THAT FULL BOTTOM SEARCH HAS BEEN ACHIEVED AND THE DATA HAVE NOT BEEN INSPECTED FOR DANGERS TO NAVIGATION. THESE DATA ARE NOT INTENDED FOR NAVIGATION.
