As part of the USGS's California State Waters Mapping Project, depth to base of last glacial maximum within the 3-nautical mile limit between Gaviota and Hueneme Canyon was extracted from seismic-reflection data collected in 2007 (USGS activity (Z-3-07-SC) and 2008 (S-7-08-SC). Depths range from 7 to 568 m with a mean of 67 m and a standard deviation of 65 m.
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.

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

The chirp sonar instrument is deployed under the research vessel with about 10m of variation in position. The sparker position may vary as much as 20m from the navigation reference on the vessel.
Chirp and sparker seismic-reflection data from USGS field activity Z-3-07-SC and chirp data from field activity S-7-08-SC were imported to SEISWORKS. (Ray Sliter, rsliter@usgs.gov)
