This polygon shapefile is part of a data release of the Oregon outer continental shelf (OCS) proposed wind farm map site. The polygons have attribute values for Coastal and Marine Ecological Classification Standard (CMECS) geoforms, substrate, and modifiers. CMECS is the U.S. government standard for marine habitat characterization and was developed by representatives from a consortium of federal agencies. The standard provides an ecologically relevant structure for biologic, geologic, chemical, and physical habitat attributes. This map illustrates the geoform and substrate components of the standard. The CMECS classes are documented at https://www.fgdc.gov/standards/projects/FGDC-standards-projects/cmecs-folder/CMECS_Version_06-2012_FINAL.pdf....

These data depict littoral cells along the West Coast of the United States, as polygon extents across the shoreline of Washington, Oregon, and California. A littoral cell is a reach of the coast that is isolated sedimentologically from adjacent coastal reaches and that features its own sources and sinks. Isolation is typically caused by protruding headlands, submarine canyons, inlets and some river mouths that prevent littoral sediment from one cell to pass into the next (Beachapedia). The data are a compilation of existing data sources from Washington Department of Ecology (WDOE), Oregon Coastal Management Program (OCMP), and California Coastal Sediment Management Workgroup (CSMW). There is companion data set with...

Introduction High-resolution swath bathymetry and backscatter were collected in the mouth of the Columbia River (MCR) as part of the Office of Naval Research (ONR) funded River and Inlet Dynamics Experiment in 2013. The goal of the U.S. Geological Survey’s component of the research was to evaluate the various hydrodynamic and sediment transport processes in the Columbia River estuary entrance using a combination of field observations coupled with Delft3D model simulations. The MCR is a dynamic estuary inlet with large waves, large tidal currents, and a significant river discharge, resulting in strong estuarine circulation. The field component of the study consisted of an intensive in-situ experiment including bottom-mounted...
