Data were collected aboard the USGS R/V Parke Snavely during field activity 2018-645-FA, using an EdgeTech SB-512i sub-bottom profiler. Sub-bottom acoustic penetration spans several tens of meters and is variable by location. Purpose: Data were acquired to support the USGS geologic hazards projects to aide hazard assessment of shallow faulting, slope stability, and submarine landslides along the western Santa Barbara Channel. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Native_Data_Set_Environment: SEG-Y rev 1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Identified as best available version Logical_Consistency_Report: No formal logical accuracy tests were conducted, but quality control was conducted during data acquisition. 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: Estimated to be no less than 3 m due to total propagated uncertainties of navigation as well as data processing. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: A formal accuracy assessment of the vertical positional information in the data set has not been conducted. Lineage: Process_Step: Process_Description: Chirp sub-bottom data were collected using an Edgetech-512i sub-bottom profiler. Data were corrected for sub-bottom profiler tow depth, converted to envelope, swell corrected and muted above the seafloor. Navigation was converted from seconds of arc to UTM zone 11N.
