A Peruvian navy diver enters the water during a joint nation underwater survey of a sunken ship in the harbor of Panama City, Panama, on Aug. 16, 2010. Local port authorities asked for the assistance of Mobile Diving and Salvage Unit 2 to see if the 12-year-old sunken ship could be moved. Mobile Diving and Salvage Unit 2 is participating in Navy Diver-Southern Partnership Station, a multinational partnership engagement designed to increase interoperability and partner nation capacity through diving operations.
