Depth to Transition, Point Sur to Point Arguello, California Mini-sparker This part of DS 781 presents data for the depth-to-transition map of the Point Sur to Point Arguello, California, region. The raster data file is included in the "DepthToTransition_PointSurToPointArguello.zip," which is accessible from https://doi.org/10.5066/P97CZ0T7. 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 Sur and Point Arguello was generated from seismic-reflection data collected between 2008 and 2014, and supplemented with geologic structure (fault and fold) information following the methodology of Wong (2012). Water depths determined from bathymetry data were added to the sediment thickness data to provide information on the depth to base of the post-LGM unit. Reference Cited: Wong, F. L., Phillips, E.L., Johnson, S.Y., and Sliter, R.W., 2012, Modeling of depth to base of Last Glacial Maximum and seafloor sediment thickness for the California State Waters Map Series, eastern Santa Barbara Channel, California: U.S. Geological Survey Open-File Report 2012-1161, 16 p.

Faults - Point Sur to Point Arguello, California Mini-sparker This part of DS 781 presents data for the faults of the Point Sur to Point Arguello, California, region. The vector data file is included in the "Faults_PointSurToPointArguello.zip," which is accessible from https://doi.org/10.5066/P97CZ0T7. Faults in the Point Sur to Point Arguello region are identified on seismic-reflection data based on abrupt truncation or warping of reflections and (or) juxtaposition of reflection panels with different seismic parameters such as reflection presence, amplitude, frequency, geometry, continuity, and vertical sequence. Faults were primarily mapped by interpretation of seismic reflection profile data collected by the U.S. Geological Survey between 2008 and 2014. Samuel Y Johnson
Folds-Point Sur to Point Arguello, California Mini-sparker This part of DS 781 presents data for the folds of the Point Sur to Point Arguello, California, region. The vector data file is included in the "Folds_PointSurToPointArguello.zip," which is accessible from https://doi.org/10.5066/P97CZ0T7. Folds in the Point Sur to Point Arguello region are identified on seismic-reflection data based on warping and tilting of reflections. Folds were primarily mapped by interpretation of seismic reflection profile data collected by the U.S. Geological Survey between 2008 and 2014 and interpretation of high-resolution bathymetry data.

Isopachs-Point Sur to Point Arguello, California Mini-sparker This part of DS 781 presents data for the isopachs of the Point Sur to Point Arguello, California, region.
