In 2018 and 2019 the NOAA ships Rainier and Fairweather collected multibeam bathymetry data in 5 areas along the southern Cascadia Margin offshore northern California and southern Oregon as part of a cooperative project between the U.S. Geological Survey, Pacific Coastal and Marine Science Center and NOAA. These regions were combined with other publicly available multibeam bathymetry data. The surface was generated to assist research projects studying offshore geohazards including mapping faults, submarine landslides, sediment transport pathways, and seafloor seeps. These data are not intended to be used for navigation.
