Description:

Abstract:

This part of USGS Data Series 781 (Golden, 2019) presents 2-m-resolution bathymetry data for the Offshore of Point Buchon, California, map area. Bathymetry data were collected by Fugro Pelagos in 2008 using a combination of 400-kHz Reson 7125, 240-kHz Reson 8101, and 100-kHz Reson 8111 multibeam echosounder systems. The data were post-processed by the California State University Monterey Bay Seafloor Mapping Lab and the University of California Santa Cruz Center for Integrated Spatial Research. The bathymetry data are available as a georeferenced TIFF image.

Purpose:

The surveys were conducted to map surficial geology and benthic habitat as part of the USGS California Seafloor Mapping Program (CSMP), a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA). These data are intended to provide regional bathymetric information in California State waters for offshore resource and ecosystem management. These data are also intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to help identify geomorphologic features and surficial lithology. These data are not intended to be used for navigation.

Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: Not applicable for raster data.

Logical_Consistency_Report: No formal logical accuracy tests were conducted.
Completeness_Report:

Dataset is considered complete for the area mapped with MBES data.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The POS MV position and motion compensation system has a horizontal positional accuracy of about 0.5 m with DGPS corrections and roll and pitch accuracies of about 0.02 degrees (http://www.measutronics.com/wp-content/uploads/2011/01/posmv320_specifications.pdf). Accuracies of final products may be lower due 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:

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.

Process_Description:

Multibeam echosounder (MBES) data were collected by Fugro Pelagos in 2008 using a combination of 400-kHz Reson 7125, 240-kHz Reson 8101, and 100-kHz Reson 8111 multibeam echosounder systems. An Applanix POS-MV (Position and Orientation System for Marine Vessels) was used to accurately position the vessels during data collection, and it also accounted for vessel motion such as heave, pitch, and roll, with navigational input from GPS receivers. Smoothed Best Estimated Trajectory (SBET) files were postprocessed from logged POS-MV files. Sound-velocity profiles were collected with an Applied Microsystems (AM) SVPlus sound velocimeter. Soundings were corrected for vessel motion using the Applanix POS-MV data, for variations in water-column sound velocity using the AM SVPlus data, and for variations in water height (tides) and heave using the postprocessed SBET data (California State University, Monterey Bay, Seafloor Mapping Lab, 2016). The raw bathymetry data were processed into mosaics using Caris HIPS. The bathymetry mosaics were then exported as two georeferenced TIFF images, a 2-meter resolution image for depths less than 80 meters and a 5-meter resolution image for deeper areas. The images were subsequently mosaiced into a single 2-meter resolution image for this data release.

Process_Date: 2016

Process_Step:

Process_Description:

The 2-m-resolution bathymetry images were mosaiced and clipped into a single geotiff mosaic for the study area by the University of California Santa Cruz Center for Integrated Spatial Research using ArcGIS 10.
