The Olympic Coast National Marine Sanctuary (OCNMS), the Active Tectonics & Seafloor Mapping Lab (AT&SML) at the Oregon State University, and several contributing partners worked together to compile raw seafloor mapping data and stitch them together into a seafloor atlas.
The group remapped data when necessary, standardized the classifications and methodologies, and applied existing ground-truth information as appropriate. Data in the seafloor atlas include seabed habitat, backscatter, bathymetry, structural data, and remote sensing with multibeam sonar information. The atlas shows high resolutions of the primary surficial substrate types from the shoreline to 700 fathoms.
The image below is an example of the online atlas and references the rest of the atlas in the top right.
