Isopachs--Santa Barbara Channel, California

Metadata Updated: October 26, 2023

This part of DS 781 presents data for the isopachs for the Santa Barbara Channel, California, region. The vector data file is included in "," which is accessible from As part of the USGS's California Seafloor Mapping Program, a 50-m grid of sediment thickness for the seafloor within the 3-nautical-mile limit of California's State Waters from the Offshore of Refugio Beach map area to the Hueneme Canyon and vicinity map area was generated from seismic-reflection profile data, collected in 2007 and 2008 (USGS activities Z-3-07-SC and S-7-08-SC), supplemented with outcrop and geologic structure data from DS 781. The resulting grid covers an area of approximately 600 sq km. Sediment thickness contours (isopachs) at 2.5-meter intervals were derived from this grid.
