Abstract:
This part of DS 781 presents data for the depth-to-transition map of the Point Conception to Hueneme Canyon, California, region. The raster data file is included in "DepthToTransition_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). 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. This depth-to-transition layer was merged with a previously published depth-to-transition grid for the Santa Barbara Channel region (available at https://pubs.usgs.gov/ds/781/SantaBarbaraChannel/data_catalog_SantaBarbaraChannel.html).

Attribute_Accuracy:
Attribute_Accuracy_Report:
Data points are approximately 1 m apart along tracklines and 1000-2000 m apart between tracks. 50-m cell size for interpolation is better supported along track than between.
Logical_Consistency_Report: Not applicable for raster data.
Completeness_Report:
Sediment thickness data points exported from Seisworks profiling software were processed within the California 3-nmi limit.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The chirp sonar instrument is deployed under the research vessel with about 10m of variation in position. The sparker position may vary as much as 20m from the navigation reference on the vessel.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Estimated to be approximately 1 m, along the track lines where data is well constrained, but may be much greater in areas where interpolation occurred.

Process_Step:
Process_Description:
Water bottom (seabed) and depth to base of the Last Glacial Maximum (LGM) horizons were digitized from seismic-reflection data using Seisworks software. 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 1,500 m/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 (see https://www.sciencebase.gov/catalog/item/589cba61e4b0efcedb76497e). Further refinement of this sediment thickness map and the 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/).
