�� Description:�

�� Abstract:� Information produced from this project contributes new seafloor images and maps that will be used to assess regional geology and characterize habitats critical to fisheries management and planning of Marine Protected Areas (MPAs), as required by Federal mandates stated in the Magnunson-Stevens Fishery Conservation and Management Act and Sustainable Fisheries Act. Seafloor mapping effort was focused on priority areas outlined by multi-agency participants of the California Marine Habitat Task Force (CMHTF) Strategic Planning Meeting (1/20-21/2000).

�� Purpose:� These data are presented as part of a program objective to identify, quantify and synthesize existing information critical to the understanding of the linkage between fisheries and habitats. Before regional exploration and site specific studies are undertake in regard to Essential Fish Habitats (EFH), all possible data that can be used to characterize substrate of EFH should be examined and, where possible, used to delineate habitat. To complete this goal we identified, catalogued, digitized, re-interpreted, and archived proprietary industry data including side scan sonar mosaics, subbottom seismic profiles and bathymetry not previously available to the general scientific community for the purpose of providing critical marine habitat maps of the California margin. In areas where industry data did not overlap the recommendations of the CMHFT, the CSUMB state-of-the-art seafloor mapping facility acquired and processed new data.

�� Supplemental_Information:� Data Acquisition: Bathymetric and backscatter (sidescan) data were collected aboard the R/V MacGinnite using a Reson 8101 multibeam echosounder. Differential GPS (DGPS) position data were generated by a Trimble 4700 GPS with differential corrections provided by a Trimble ProBeacon receiver. A TSS HDMS heading and motion sensor provided heave, pitch, heading, and roll data. Coastal Oceanographics Hypack software was used for survey design and execution. All raw data were logged using a Triton-Elics International (TEI) Isis data acquisition system. Water column sound velocity� profiles collected using an AML SV+ sound velocity profiler.

�� Process_Step:�

�� Process_Description:� Bathymetric data were post-processed using CARIS HIPS hydrographic data cleaning system software. Soundings were corrected for vessel motion using TSS HDMS data, variations in water column sound velocity using AML SV+ data, and adjusted to MLLW using predicted tide charts for the local region. Erroneous soundings were removed in CARIS HIPS. Geotiffs were exported from CARIS HIPS Spatial Editor with 1m and 2m resolution in sunshaded grayscale and rainbow 16 color imagery. Sun azimuth and elevation varies.
