151207-N-ZZ999-036 ATLANTIC OCEAN (Dec. 7, 2015) -- Blair Atcheson and George Schwarz, underwater archaeologists with Naval History and Heritage Command, prepare a magnetometer to survey a site that may be the wreck of early 19th Century Schooner USS Revenge in the waters off Watch Hill, R.I., Dec. 7, 2015. Commanded by Commodore Oliver Hazard Perry, Revenge ran aground in thick fog and heavy swells on the night of Jan. 9, 1811 and subsequently sank. The area is home to a number of other 19th century vessels that shared the same fate as Revenge over the past 200 years. (U.S. Navy photo by Heather Brown/Released)
