Location: Maro Reef, Northwestern Hawaiian Islands
Type of Ship: Tanker
Depth: 80 feet
After years of searching, marine researchers from the National Oceanic and Atmospheric Administration discovered a sunken 524-foot US Navy tanker in August. The tanker transported fuel during World War II and the Korean War, but ultimately took a plunge in 1957 after hitting Maro Reef at full speed. The Navy rescued all 42 crewmembers on board, but a lack of coordinates made it difficult to locate the tanker afterward. The ship is nestled in one of the largest marine conservation areas in the world, the Papahānaumokuākea Marine National Monument, which covers roughly 140,000 square miles of ocean. These waters are home to about 60 known shipwrecks. The USNS Mission San Miguel now lives on as an artificial reef.
