Description This part of DS 781 presents data for the isopachs for the Bolinas to Pescadero, 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 between offshore Offshore Bolinas and offshore Pescadero was generated from seismic-reflection data collected between 2006 and 2010, supplemented with outcrop and geologic structure (fault) information following the methodology of Wong (2012).
