Mr. Overfield is the Resources and UnderSea Threats (RUST) database coordinator for the National Marine Sanctuaries Resource Protection Team. The mission of the RUST database is to develop, maintain, and manage an active and comprehensive inventory of undersea threats and potential environmental hazards within United States waters. RUST focuses specifically on locating and identifying those underwater threats that may be pollution hazards such as abandoned wellheads, pipelines, platforms, and sunken tankers. His participation in the Deep Gulf Shipwrecks of World War II project will allow data collection on ferrous-hulled vessels and the effect of corrosion in the deep water environment of the Gulf.
