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. In this webcast, we talk live with Dr. Ballard as he explores the Mediterranean's Straits of Sicily. Learn about the Nautilus' latest discoveries and the history of ocean exploration. The Nautilus has discovered several well-preserved shipwrecks on their mission, from ancient Greek trading vessels to modern sailboats. Join us as we talk with chief scientist Katy Croff Bell live aboard the Nautilus and see the latest video of their discoveries. Located in the Atlantic Ocean off the coast of Portugal, the seamounts of Gorringe Bank rise nearly 5000 meters from the sea floor -- as tall as Europe's Alps. Join us as we talk live with scientists aboard the Nautilus as they explore these geologically active and biologically rich submarine mountains. Join the Exploratorium as we connect live for the first time with the E/V Nautilus as it sails the Mediterranean Sea south of Spain. We talk with scientists on the ship and learn about the ship's amazing capabilities and the 2011 exploration mission.

See the subtle, mesmeric effects revealed by slow-motion observation of three iconic exhibits: Circling Wave Umbrella, in which spinning fabric forms pockets of swirling air; Rift Zone, a miniature geothermal landscape created by air bubbling through fine sand; and Vortex, a swirling vortex of water in a hydrodynamic dance with gravity. The ground under our San Franciscan feet is constantly on the move. Join Exploratorium educator Ken Finn as we visit some spots around town where exposed rocks reveal the tale of an active earth. San Francisco's meteorological landscape is as unique as its social landscape. Tune in as we investigate why our city has many microclimates.
