Archaeologist James Delgado, host of National Geographic International Television's "The Sea Hunters," which also features best-selling author Clive Cussler, has announced the discovery of a forgotten Civil War submarine, the Sub Marine Explorer , on a deserted island on Panama's Pacific coast. Delgado's account of the sub's history and discovery was announced at a recent press conference and is featured in his new book, Adventures of a Sea Hunter: In Search of Famous Shipwrecks (Vancouver: Douglas & McIntyre, 2004). News of the discovery comes as the U.S. Navy and the National Oceanic and Atmospheric Administration continue their search for the USS Alligator , the Navy's first submarine, which foundered off the North Carolina coast in 1863, and work continues to preserve and study the remains of the Confederate submarine H. L. Hunley in Charleston, South Carolina.
