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.
