Watch highlights from our live webcasts with the E/V Nautilus as she explored the Mediterranean and Black Seas searching for shipwreck, deep sea vents and the communities of organisms that live in these extreme environments. Join the Exploratorium for our final webcast with researchers on board the Nautilus. We discuss the highlights of their three month expedition to the Mediterranean and Black Seas, as well as to the eastern Atlantic Ocean. Learn about hydrothermal vents, organisms living in extreme environments and ancient shipwrecks. Best known for his discovery of the wreck of the RMS Titanic, Nautilus expedition leader Dr. Robert Ballard is one of the world's most famous ocean explorers.
