Purpose: These data were collected as part of USGS efforts to better understand the fault geometry of the Hayward and Rodgers Creek faults beneath the bay. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Logical_Consistency_Report: No formal logical accuracy tests were conducted 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. Due to attenuation of the chirp signal by bay muds and persistent natural gas layers in San Pablo Bay sediments, we were only able to image the upper 2 to 5 meters of the sub-seafloor.
