Title: FIse1mGS
Description:
Abstract: Geophysical techniques that help identify and define large-scale
marine benthic features are valuable in appraising essential habitats of marine
benthic fish assemblages. Interpretations and verification of sidescan sonar,
swath bathymetry, and backscatter imagery are useful tools for characterizing
these habitats. Bathymetric and backscatter (sidescan) data were collected for
the California Department of Fish and Game by the Seafloor Mapping Lab at
California State University, Monterey Bay
using a Reson 8101 multibeam echosounder.
Purpose: To collect and process bathymetric and backscatter (sidescan
sonar) data for marine habitat classification.
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 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 resolution in sunshaded
grayscale and rainbow 16 color imagery. Sun azimuth and elevation varies.
