Dataset description: Sediment Thickness--Point Conception to Hueneme Canyon, California

This part of DS 781 presents data for the sediment-thickness map of the Point Conception to Hueneme Canyon, California, region. The raster data file is included in "SedimentThickness_PointConceptionToHuenemeCanyon.zip," which is accessible from https://doi.org/10.5066/F7891424. As part of the USGS's California State Waters Mapping Project, a 50-m grid of sediment thickness for the seafloor within the 3-nautical mile limit between Point Conception and Hueneme Canyon was generated from seismic-reflection data collected in 2014 (USGS activity 2014-632-FA) supplemented with outcrop and geologic structure (fault) information following the methodology of Wong (2012). This sediment thickness layer was merged with a previously published sediment thickness grid for the Santa Barbara Channel region (available at https://pubs.usgs.gov/ds/781/SantaBarbaraChannel/data_catalog_SantaBarbaraChannel.html).
