The NAMSS website has the marine data. The data is in the Pacific Gas and Electric Company section. The Offshore Pt. Buchon 2D data set can be directly downloaded from the website. These are large files and may take time to download. The size of the files is roughly 4GB. Because of the files’ size, the 3D data sets are available upon request from the agency. Please follow the instructions on the NAMSS page to request the data sets. Visit USGS National Archive of Marine Seismic Surveys (NAMSS).
