Description160907-N-TH437-031 (29535755445).jpg	160907-N-TH437-031 NORTH SEA (Sept. 7, 2016) — George Schwarz, an underwater archaeologist with the Naval History and Heritage Command (NHHC), prepares batteries that power magnetometer survey equipment in a rigid hull inflatable boat aboard the Military Sealift Command rescue and salvage ship USNS Grasp (T-ARS 51), Sept. 7, 2016. Underwater archaeologists from NHHC are aboard Grasp conducting a remote sensing survey of a shipwreck that may be that of Revolutionary War ship Bonhomme Richard.
