Jeffrey Pardee, Panamerican diver tender, examines diver James Duff’s equipment and topside air supply during an initial dive event Jan. 22, 2015, on the Savannah River near Old Fort Jackson. Duff, a Panamerican diver and maritime archaeologist, used a rope to connect sections of the CSS Georgia wreck site scuttled on the river floor. A network of ropes connects wreck site artifacts and assists divers to navigate through the mucky underwater floor of the Savannah River. CSS Georgia recovery is the first action begun under the construction phase of the Savannah Harbor Expansion Project (U.S. Army Corps of Engineers photo by Chelsea Smith.)
