Description:

Abstract:

The sidescan sonar image of the nearshore seafloor (0 to 100 m water depths) of the Santa Barbara Channel area was mosaicked from data collected in 2005. A 234 kHz Interferometric Submetix Swath Bathy Sonar System; SEA Swath Processor, v. 2.05, SEA Grid Processor v. 2.05, was used for geophysical surveying. The 2005 survey was navigated with a CodaOctopus, Model F180, Differential Global Positioning System (DGPS). 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.
