Voyages of Discovery: NOAA's Okeanos Explorer - Underwater Volcanoes and Hydrothermal Vents

Look over the shoulders of ocean explorers as they map and send their ROV into the little-known and unknown regions of the deep sea. "Voyages of Discovery" connects the Exploratorium with NOAA's newest ship, the Okeanos Explorer, currently in the Pacific Ocean near Indonesia, as it carries out its first exploration voyage. In this program, we learn about underwater volcanoes and hydrothermal vents and see how scientists explore underwater geology with mapping and ROV technology.
