Description:

Abstract:

This part of DS 781 presents data for the sediment-thickness map of the Santa Barbara Channel, California, region. The raster data file is included in "SedimentThickness_SantaBarbaraChannel.zip," which is accessible from https://pubs.usgs.gov/ds/781/SantaBarbaraChannel/data_catalog_SantaBarbaraChannel.html.
As part of the USGS's California Seafloor Mapping Program, a 50-m grid of sediment thickness atop the bedrock at the Last Glacial Maximum horizon for the seafloor within the 3-nautical-mile limit of California's State Waters from the Offshore of Refugio Beach map area to the Hueneme Canyon and vicinity map area was generated from seismic-reflection profile data, collected in 2007 and 2008 (USGS activities Z-3-07-SC and S-7-08-SC), supplemented with outcrop and geologic structure data from DS 781. The resulting grid covers an area of approximately 600 sq km. Sediment thickness contours (isopachs) at 2.5-meter intervals were derived from this grid and are also available in this data release

Purpose:

These data are intended for science researchers, students, policy makers, and the general public. This information is not intended for navigational purposes.The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.

Supplemental_Information:

Additional information about the field activities from which this data set was derived are available online at:

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Data points are approximately 1 m apart along tracklines and 1,000-2,000 m apart between tracks. 50-m cell size for interpolation is better supported along track than between.

Logical_Consistency_Report: Not applicable for raster data.
Completeness_Report:

Sediment thickness data points exported from Seisworks profiling software were processed within the California 3-nmi limit, omitting values over Hueneme Canyon.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The chirp sonar instrument is deployed under the research vessel with about 10 m of variation in position. The sparker position may vary as much as 20 m from the navigation reference on the vessel.

Process_Step:

Process_Description:

Metadata was modified to bring up to current USGS PCMSC standards. USGS Thesaurus and keywords were added, added keywords section with USGS persistent identifier as theme keyword, Point of Contact and Metadata Contact information was updated, and Process Steps were refined. Information about the data available for download and different Network Resource Name links and details were given in the Standard Order Process section. Minor typos were corrected. No data information was changed. The metadata available from a harvester may supersede metadata bundled within a download file. Users are advised to compare the metadata dates to determine which metadata file is most recent.

Fees: none

Technical_Prerequisites:

The downloadable data file has been compressed with the "zip" command and can be unzipped with Winzip (or other tool) on Windows systems. To utilize these data, the user must have software capable of uncompressing the WinZip file and importing and viewing an Esri ArcMap TIFF. Users should download the ArcGIS Project File, SantaBarbaraChannelGIS.mxd.zip, a compressed (with the "zip" command) version of the ArcMap document (.mxd) that has all the data layers loaded in the table of contents for the Santa Barbara Channel region, and has all the data symbolized as on the map sheets. Download and save this ArcGIS project file, including all data layers, to the directory the user has created for this GIS.
