Abstract

In 1987, the wreck site of USS Monitor was the scene of a systematic gathering of baseline archaeological data to assess the condition of the wreck. Advanced oceanographic tools, a ROV, and a sonar-based positioning system were used to carry out the project. Four tasks were planned and executed: (1) to define the extent of the archaeological site through analysis of the artifact scatter away from the wreck proper; (2) to make a controlled photographic map of the hull in plan and elevation views; (3) to study the corrosion processes at the site; and (4) to acquire 35-mm stereo photographs of selected specific details of the vessel’s construction for historical engineering analysis. Additionally, the opportunity arose to carry out a fifth task, the acquisition of detailed, close-range, high-resolution imagery of the hull by sector-scanning sonar. With the present study accomplished it became apparent that the site is rapidly being destroyed by human and natural causes. Active steps to preserve the Monitor are recommended up to and including the complete recovery of the wreck and its contents.
