National Geographic: The Quest for Noah's Flood

"The Quest for Noah's Flood" sends Titanic finder Robert Ballard back to the Black Sea in search of ancient ships. He finds evidence supporting a theory that a flood formed the Sea some 7000 years ago, one that could have inspired the Genesis story as well as the Babylonian Epic of Gilgamesh. And on the Black Sea floor (in an oxygen-free "dead zone") Ballard's crew finds an intact 1500-year-old ship. Michael Carroll narrates.
