Episode 502: Sunken Stories

The oceans are a graveyard of man’s seafaring adventures. Today, underwater archaeologists are scouring the seafloor for clues to our maritime past. Changing Seas joins members of the National Association of Black Scuba Divers, or NABS, as they learn how to map shipwrecks in Biscayne National Park. Teaming up with researchers from the Florida Keys National Marine Sanctuary and the Mel Fisher Maritime Museum, volunteers return to south Florida and apply their skills on a mysterious 19th Century slave ship. Later, we follow explorers from the Aurora Trust in Key Largo, Florida who use sonar and other remote sensing tools to create detailed maps of the ocean bottom.
