Resource Abstract:
- description: The sidescan sonar image of the nearshore seafloor (0 to 100 m water depths) of the southern Anacapa Passage
area was mosaicked from data collected in 1999 and 2000. 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 2000 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 (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. The sidescan data were
processed using USGS MIPS sonar processing software (Chavez, 1984). See <http://walrus.wr.usgs.gov/nearshorehab> for
more information about this data set.; abstract: The sidescan sonar image of the nearshore seafloor (0 to 100 m water depths)
