Chuuk Lagoon, formerly known as Truk Lagoon, is a sheltered body of water in the central Pacific. North of New Guinea, it is located mid-ocean at 7 degrees North latitude, and is part of Chuuk State within the Federated States of Micronesia.
In 1969, French oceanographer Jacques Cousteau and his team explored Truk Lagoon. Following Cousteau's 1971 television documentary about the lagoon and its ghostly remains, the place became a scuba diving paradise, drawing wreck diving enthusiasts from around the World to see its numerous, virtually intact sunken ships.The shipwrecks and remains are sometimes referred to as the "Ghost Fleet of Truk Lagoon".
Scattered mainly around the Dublon, Eten, Fefan and Uman islands within the Truk group, a number of the shipwrecks lie in crystal clear waters less than fifteen meters below the surface.Tourism, especially scuba diving among the many wrecks of Truk Lagoon, is the island's main industry. Copra, dried coconut meat, is the only cash crop and output is relatively insignificant. Most of the inhabitants of outlying islands engage in subsistence activity only.
