FILE PHOTO WASHINGTON (June 23, 2014) Kate Morrand, underwater archeology conservator at the Naval History and Heritage Command, removes an inert cannonball from a wooden box in which the artifact was found. The cannonball was one of more than 30 artifacts that the command received after conservation from the Clemson University Restoration Institute. Scientists retrieved the artifacts from the sunken confederate states ship CSS Alabama and have undergone years of conservation in order to stabilize them and make them ready for eventual display.
