The vector data file is included in "Isopachs_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). This polyline shapefile provides the sediment-thickness isopachs to accompany the grid layer. Reference Cited: Wong, F.

The difference between the two horizons was exported from Seisworks for every shot point as XY coordinates (UTM Zone 10) and two-way travel time (TWT). The thickness was determined by applying a sound velocity to the TWT of 1,500m/sec in water and 1,600 m/sec velocity in sediment, resulting in sediment thickness values. Source_Used_Citation_Abbreviation: 2014-632-FA Process_Date: 2015 Process_Step: Process_Description: XY locations and sediment thickness values Z were imported to ArcGIS format as points and interpolated to a preliminary surface with TopoRaster from which isopachs (thickness contours) were extracted at 2.5 m intervals. Further refinement of the sediment thickness map (see https://www.sciencebase.gov/catalog/item/589cba9fe4b0efcedb764ca2) and this isopach shapefile was accomplished through several iterations of manual editing to incorporate geology and fault information following the methodology of Wong (2012; see http://pubs.usgs.gov/of/2012/1161/).
