Online_Linkage: https://doi.org/10.5066/P95HX7GB Description: Abstract: The U.S. Geological Survey collected high-resolution single channel minisparker data between Point Sal and Piedras Blancas in 2008 and 2009 with support from the Pacific Gas and Electric (PG&E) CRADA and the USGS Coastal and Marine Geology program. Reprocessing of this data in 2018 improved vertical resolution of the stratigraphy and structural deformation of the original data and was funded by an additional CRADA with PG&E. Purpose: This work will aid the USGS in reviewing and refining existing interpretations, hazard assessments and development of new hypotheses. Particular targets include the Hosgri-San Gregorio fault system, and the Los Osos, and Shoreline faults. The ultimate goal of this work for both parties is to enhance earthquake hazard assessments by providing a more comprehensive understanding of regional geologic framework, seismic sequence stratigraphy and hazard assessment. These data and information are intended for science researchers, students, policy makers, and the general public.

Browse_Graphic_File_Type: PNG Data_Set_Credit: This dataset was collected by the U.S. Geological Survey in 2008 and 2009. Work was funded in part by a CRADA agreement between PG&E and the USGS and these data were made publicly available in 2009 (Sliter and others, 2009). Native_Data_Set_Environment: Single channel minisparker data were recorded in SEG-D rev. 2.1 format (https://seg.org/Portals/0/SEG/News%20and%20Resources/Technical%20Standards/seg_d_rev2.1.pdf) using Geometrics CNT-1 seismic acquisition software. A SIG 2Mille 50-tip minisparker operated at 500J was used as the seismic source and SEG-D format data were acquired using a 15-meter-long single channel hydrophone that was towed aft of the stern. Survey speeds were approximately 4.5 knots. Data were converted to SEG-Y format and were minimally processed and released in 2009 (Sliter and others, 2009). For reprocessing efforts utilized SIOSEIS and Seismic Unix software. Cross_Reference: Citation_Information: Originator: Sliter, Ray. W. Originator: Triezenberg, Peter J. Originator: Hart, Patrick E.

Online_Linkage: https://pubs.usgs.gov/of/2009/1100/ Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Quality control was conducted during acquisition. Some seismic profiles have gaps in them due to system crashes or intentional shutdowns as required, under terms of our operating permit, to protect marine mammals. Minor swell correction artifacts exist at line starts and ends as well as in areas where seafloor amplitudes are low. Logical_Consistency_Report: Quality control was conducted during acquisition and processing to ensure consistency of SEG-Y header navigation and seismic-reflection data that matches bathymetry along the tracklines. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal positional accuracy of the seismic data thus linked to the Research Vessel Parke Snavely’s position is estimated to be within 30 meters (Sliter and others, 2009).

This data release contains reprocessed single channel seismic data. Process_Step: Process_Description: Single channel minisparker data collected during USGS field activities S06-08-SC and S-6-09-SC were converted to SEG-Y format and were minimally processed and released in 2009 (Sliter and others, 2009). Source_Used_Citation_Abbreviation: original SEG-Y format data Process_Date: 20090219 Process_Step: Process_Description: Data released in 2009 was bandpass filtered and swell corrected using SIOSEIS software. Data were then converted to Seismic Unix format and trace balanced, trace mixed, and a predictive deconvolution was designed for each line. Following the deconvolution, a bandpass filter was applied as well as an automatic gain control. UTM zone 10N navigation was written to header bytes 73 and 77.
