The raster data file is included in "DepthToTransition_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 Project, a 50-m-resolution grid of depth to the transgressive surface of the Last Glacial Maximum within California State Waters between Refugio Beach and the Hueneme Canyon and vicinity map area was generated from seismic-reflection 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 sediment-thickness grid was subtracted from regional bathymetry to determine the depth to the last glacial maximum transitional surface. The resulting grid covers an area of approximately 600 sq km. Contours at 5-meter intervals were derived from this depth-to-transition 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.

(Ray Sliter, rsliter@usgs.gov). Process_Date: 2011 Process_Step: Process_Description: X, Y locations and sediment thickness value Z imported to ArcGIS format as points, interpolated to preliminary surface with TopoRaster. Because processing of the related sediment-thickness map resulted in an interpolated surface that diverged from the data exported from Seisworks, the final transgressive surface was calculated by subtracting sediment thickness from multibeam bathymetry. (Florence Wong, fwong@usgs.gov; Eleyne Phillips, ephillips@usgs.gov) Process_Date: 2011 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.
