On August 11, scientists set out to explore a potential shipwreck target that had been mapped during a previous Okeanos Explorer cruise. They believed that the wreck might be the Japanese Imperial Naval Destroyer, Hayate, which was sunk during the Battle of Wake. However, the shipwreck was instead found to be that of the Amakasu Maru No. 1, which was a Japanese water tanker that was sunk by a U.S. submarine in 1942. For more information, click here.
