Description:

Abstract:

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. (available at https://pubs.usgs.gov/of/2012/1161/).

Purpose:

To expand geologic mapping to the seafloor within the California's State Waters, to update coastal geologic mapping, and to contribute to a uniform regional geologic database, which can be used geographic information systems. Additionally, to aid in assessments and mitigation of geologic hazards in the Point Sur to Point Arguello coastal region and to provide sufficient geologic information for land-use and land-management decisions both onshore and offshore. This information is not intended for navigational purposes.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The data points from seismic-reflection profiles are dense along tracklines (about 1–2 m apart) and sparse between tracklines (typically 800–1,000 m apart). 50-m cell size for interpolation is better supported along track than between.

Logical_Consistency_Report:

No formal logical accuracy tests were conducted. All vector geometry and attributes are present.

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 sparker position may vary as much as 20 m 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:

all sources listed above, with the exception of “bathy,” were used in the creation of this layer

Process_Date: 2017
Source_Produced_Citation_Abbreviation: SedimentThicknessPoints

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 this sediment thickness map and the isopach shapefile (see https://pubs.usgs.gov/ds/781/PointSurToPointArguello/data/Isopachs_PointSurToPointArguello.zip) 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/).

Process_Step:

Process_Description:

The depth to the base of the post-Last Glacial Maximum (LGM) unit was generated by adding the thickness data to water depths from the bathymetry data.
