This Final Report summarizes the procedures utilized and the results of the mapping efforts reached as a result of the preparation of the deliverables for the project, "Mapping Areas of Hard Bottom and Other Important Bottom Types: Outer Continental Shelf and Upper Continental Slope." Some of the tasks and approaches evolved during the course of the project and are documented below. The geohazards on the upper continental shelf were mapped from a variety of sources, including high-resolution geohazard seismic and industry-provided seismic surveys.
