These data were merged with other bathymetry data within the channel to create an overall, 10-m resolution bathymetric Digital Terrain Model (DTM) of the majority of the Santa Barbara Channel from Point Conception to Hueneme Canyon. 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 display the bathymetry data. These data are not intended for navigational purposes.

This report has compiled all of the bathymetry data and merged the datasets into one overall 10-m resolution Digital Terrain Model (DTM). NOAA has previously generated a 10-m Tsunami Inundation DTM of the entire channel that merged the available bathymetry data with onshore topography data. This report provides an updated bathymetry DTM that includes more recent bathymetry data included the 2010-2011 USGS bathymetry data. No attempt was made here to merge the new bathymetry DTM with onshore topography. MBARI bathymetry data from their 1998 survey of the deeper central and western channel are available in MBSystems format files from the National Geophysical Data Center (NGDC) bathymetry data server, http://maps.ngdc.noaa.gov/viewers/bathymetry/. XYZ soundings (x-coord, y-coord, depth) were extracted from the survey lines, gridded into a 10-m resolution bathymetric surface using the Fledermaus (GPC) software package, and imported into a GIS (ESRI, ArcMap). USGS bathymetry data from the 2004 survey of the deeper eastern channel are also available from the NGDC bathymetry data server. This project however used the raw survey lines from the USGS archives. Survey lines were imported into Caris HIPS/SIPS software, gridded into a 10-m base surface and imported into a GIS. Nearshore data within California State waters was collected between 2006 and 2009 by California State University, Monterey Bay and Fugro Pelagos Inc. for various seafloor habitat and geology studies. These data are available as GIS files from http://seafloor.csumb.edu/index.html. USGS nearshore data are available as GIS files from on-line reports including http://pubs.usgs.gov/of/2007/1271/ and http://pubs.usgs.gov/of/2009/1289/, as well as from soon to be published datasets. The nearshore, higher resolution bathymetry data were down-sampled to 10-m resolution grids to merge with the deeper-water grids. All datasets were transformed to UTM, zone 11, NAD83 coordinates relative to the NAVD88 ellipsoid. Using the ESRI GRID “merge” function all of the bathymetry data were combined with priority given to the most recent datasets.
