Description:
Abstract:
This report presents a digital geologic map of merged onshore and offshore geology near the Coal Oil Point area in the northern Santa Barbara Channel, southern California at a compilation scale of 1:24,000 (one inch on the map to 2,000 feet on the ground). The map depicts the distribution of bedrock units, surficial deposits, and associated deformation underlying onshore and offshore regions. The report also presents ESRI shapefile format data including geologic polygons, contacts, folds, and point features used to create the seamless onshore-offshore geologic map.
Purpose:
These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) or other software to display the geologic information and the merged topography and bathymetry digital terrain model.

Process_Step:
Process_Description:
Offshore geology was mapped by interpreting multibeam bathymetry and acoustic backscatter data, seismic profiles, sea floor photographs, and sediment samples. Heads up screen digitization of geologic polygons, geologic contacts, and folds was done over geo-referenced imagery at 1:24,000 scale in Adobe Illustrator software. The Illustrator map was imported into a GIS (Arcmap) and merged with onshore geologic polygons, contacts, and folds from Minor et al., 2009, available at <http://pubs.er.usgs.gov/usgspubs/sim/sim3001>. The onshore geology was reprojected to UTM, zone 11, NAD83 projection to match the offshore geology. Overlapping polygons along the coast, mainly beach deposits (QB), were cleaned.

Entity_and_Attribute_Information:
Overview_Description:
Entity_and_Attribute_Overview:

The data are supplied in ESRI shapefile format.
geopt.shp: Contains points recording site-specific observations and measurements, such as strike and dip of bedding. In the sbpnt.pat INFO file, the PTTYPE item lists the type of point symbol, e.g., strike and dip of inclined bedding. The STRIKE item contains the strike of bedding as well as trend of fold axis, where applicable. Strike is an azimuthal angle. Measured in degrees from 0 to 360 in a clockwise direction from North, the STRIKE value also specifies the dip direction, where the dip direction is 90 degrees clockwise relative to the STRIKE. The DIP item contains the dip of bedding as well as plunge angles, where applicable. This value is an angle measured (in degrees 0 to 90) down from the horizontal; thus, a horizontal dip is 0 degrees and a vertical dip is 90 degrees.

The DBF structure of the shapefile is listed below:
