Bathymetry - Outer Mainland Shelf and Slope, Gulf of Santa Catalina, southern California, U.S. Geological Survey 2010-2011
Entry ID: USGS_OFR_2014-1094_SantaCatalinaBathy


Summary
Abstract: In 2010 and 2011, the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC), collected bathymetry and acoustic-backscatter data from the outer shelf and slope offshore the Oceanside region in southern California. These data were acquired as part of the USGS Marine Geohazards Program. Assessment of the hazards posed by offshore faults, submarine landslides, and tsunamis are facilitated by accurate and detailed bathymetric data. The surveys were conducted using the USGS R/V Parke Snavely outfitted with a 100 kHz Reson 7111 multibeam echosounder. These metadata describe the bathymetry data provided in the report.

Purpose: These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) or other software to identify bathymetric features. These data are not intended for navigational purposes.

Quality
Horizontal_Positional_Accuracy_Report:
Estimated to be no less than 2 m, owing to water depth and total propagated uncertainties of the mapping systems, which include sonar system, position and motion compensation system, and navigation, as well as data processing that includes sounding cleaning, gridding, and datum transformations.

Vertical_Positional_Accuracy_Report:
Estimated to be no less than 20 cm, owing to water depth and total propagated uncertainties of the mapping systems, which include sonar system, position and motion compensation system, and navigation, as well as data processing that includes sounding cleaning, gridding, and datum transformations.

Use Constraints
USGS-authored or produced data and information are in the public domain. Acknowledge the U.S. Geological Survey in products derived from these data. Share data products developed using these data with the U.S. Geological Survey. This information is not intended for navigational purposes. Read and fully comprehend the metadata prior to data use. Uses of these data should not violate the spatial resolution of the data. Where these data are used in combination with other data of different resolution, the resolution of the combined output will be limited by the lowest resolution of all the data.
