Purpose: These data were acquired to support the California Seafloor Mapping Program and USGS geologic hazards projects to aide hazard assessment of southern Hosgri fault and connections to faults in Transverse Ranges and Santa Barbara Channel. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Quality control was conducted during the collection process. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Some seismic profiles have gaps in them due to system crashes, mammal shutdowns or hardware maintenance. Users are advised to read the rest of the metadata record carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Depths shown in the seismic data files are in milliseconds (round trip travel time) and are referenced to sea level. Lineage: Process_Step: Process_Description: Seismic-reflection data were collected using a minisparker system that creates an acoustic signal by discharging an electrical pulse between electrodes and a ground that generates a frequency spectrum roughly between 200 and 1,600 Hz. At boat speeds of 4 to 4.5 nm/hour, seismic traces were collected roughly every 1 to 2 meters. Water depths were generally between 50 m and 150 m, but as shallow as 10 meters near the shoreline, and as deep as 480 m for profiles crossing the Santa Barbara basin. Acoustic pulses were generated at 0.5-second intervals on most profiles; a 1-second interval was used on the few profiles collected in deeper water. Standard SEG-Y files were generated using a Triton Subbottom Logger (SBL).
