The vector data file is included in "Faults_OffshoreGaviota.zip," which is accessible from https://doi.org/10.5066/F7TH8JWJ. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Cochrane, G.R., Hartwell, S.R., Golden, N.E., Kvitek, R.G., and Davenport, C.W. (S.Y. Johnson and S.A. Cochran, eds.), 2018, California State Waters Map Series—Offshore of Gaviota, California: U.S. Geological Survey Open-File Report 2018–1023, pamphlet 41 p., 9 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20181023. The southwest-striking south strand of the Santa Ynez fault obliquely cuts the shelf in the western part of the map area. As mapped onshore by Dibblee (1950, 1988a) this fault is unique among Santa Barbara fold belt structures in that it obliquely crosses the Santa Ynez Mountains and the dominant east-west structural grain. The fault was difficult to map in the offshore, even with our dense seismic-reflection data coverage, because the pre-LGM section on the shelf includes massive "reflection free" zones, probably associated with gas or steep dips, and the adjacent slope is mainly underlain by massive to chaotic seismic facies of the Conception Fan.

Davenport 2018 pamphlet and map sheets Open-File Report 2018-1023 Reston, VA U.S. Geological Survey https://doi.org/10.3133/ofr20181023 Map elements were visually checked for overshoots, undershoots, duplicate features, polygon closure, and other errors by the lead authors and by the GIS technician(s) who created the digital database. Review drafts of the map were reviewed internally by at least two other geologists for consistency with basic geologic principles and general conformity to USGS mapping standards. Data are complete: no offshore features that could be accurately identified and represented at the compilation scale of 1:24,000 were eliminated or generalized. The smallest area represented is approximately 100 square meters. All geospatial database elements are attributed. Faults were primarily mapped by interpretation of seismic reflection profile data (see https://doi.org/10.5066/F7SX6BCD for data). Faults lines were digitized by heads-up screen digitization on to shot-point picks from seismic-line navigation data - each shot point has an associated lat/long in the survey data. Error is introduced from layback, as well as from interpretation of oblique features, so horizontal accuracy of fault and fold location is estimated to be on the order of 10 to 20 meters.
