The raster data file is included in "DepthToTransition_SantaBarbaraChannel.zip," which is accessible from http://pubs.usgs.gov/ds/781/SantaBarbaraChannel/data_catalog_SantaBarbaraChannel.html. This depth-to-transition map of the Santa Barbara Channel is published in Scientific Investigations Map 3225, "California State Waters Map Series--Hueneme Canyon and Vicinity, California" (see sheet 9). In addition, this depth-to-transition map will be published in five future California State Waters Map Series SIMs of the region (namely, the Offshore of Ventura, Offshore of Carpinteria, Offshore of Santa Barbara, Offshore of Coal Oil Point, and Offshore of Refugio Beach map areas) [note that, at the time of this writing, two of the other five SIMs have been published: the Offshore of Ventura map area (SIM 3254), and the Offshore of Carpinteria map area (SIM 3261)]. As part of the USGS's California Seafloor Mapping Program, a 50-m grid of depth to the transgressive surface of the Last Glacial Maximum was generated for the areas 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. Source data include multibeam bathymetric data (for example, sheet 1, SIM 3225) and seismic-reflection profile data, collected in 2007 (USGS cruise Z-3-07-SC) and 2008 (USGS cruise S-7-08-SC), supplemented with outcrop and geologic structure data (for example, sheets 8, 10, SIM 3225). The resulting grid covers an area of approximately 600 sq km. The depth to the transgressive surface of the Last Glacial Maximum ranges between 12 and 190 meters. 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) software to display geologic and oceanographic information.

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.
