  Description:
    Abstract:
      The sidescan sonar image of the nearshore seafloor (0 to 100 m water depths)
      of the Big Sycamore reserve area was mosaicked from data collected
      in 1998.  A Klein 2000 sidescan system was used for geophysical surveying.
      A Triton Elics Isis brand side-scan data recording system was used on the
      cruise.  The 1998 survey was navigated with a Leica Differential Global
      Positioning System (DGPS) which provided a ship position with accuracy
      of 1-5 m in DGPS mode. At times during the cruise differential signal
      was interrupted. In non-differential mode, the receiver provided a
      position with 30-50 m accuracy. A KVH Industries Inc. azimuth digital
      gyro-compass provided ship headings with 0.5 degree accuracy. Navigation
      data were recorded using Yo-Nav version 1.19 (Gann, 1992). The sidescan
      fish was towed approximately 30 m above the seafloor. The distance of
      the fish behind the ship was not known during this survey and must be
      estimated when the data are processed in order to produce the sidescan
      image mosaics.  The resolution of the processed data mosaics is 0.2 m.
      The data are presented here at a resolution of 1 m.
      This is one of a collection of digital files of a geographic
      information system of spatially referenced data related to
      the USGS Coastal and Marine Geology Program Nearshore Benthic Habitat Mapping
      Project.  See <http://walrus.wr.usgs.gov/nearshorehab> for more information.

    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 about the shallower areas of S. California coast.

    Supplemental_Information:
