Description:
Abstract:
As part of the USGS's California State Waters Mapping Project, sediment thickness for the seafloor 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). Sediment thickness ranges from 0 to 65 m with a mean of 12 m and a standard deviation of 15 m.
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.
