Site Survey
George Schwarz (NHHC) conducts a metal detector survey over a wreck site. Divers can be deployed with tools, like metal detectors, to assist in identifying or pinpointing iron objects. Some objects become overgrown with marine life and are difficult identify with the naked eye. If the object is buried, more exact location data will assist future research efforts.
