Volcanoes and Vents: A Hidden World Beneath the Sea
The Earth Institute's Lamont-Doherty Earth Observatory (LDEO) annual Public Lecture Series presents "Volcanoes and Vents: A Hidden World Beneath the Sea," with Emily M. Klein, Professor of Geology and Bass Fellow, Duke University; Visiting Senior Research Scientist, Lamont-Doherty Earth Observatory, The Earth Institute, Columbia University.
Open to the public. RSVP recommended.
Most of Earths volcanoes are on the bottom of the ocean, in a vast volcanic chain that circles the globe. Here, the ocean crusttwo-thirds of Earths surfaceis created. As tectonic plates spread apart and molten rock rises to erupt on the ocean floor, heat at mid-ocean ridges drives hydrothermal circulation, producing black smoker chimneys. In these hidden underwater worlds, researchers are finding thriving and unique biological ecosystems, leading some scientists to hypothesize that mid-ocean ridges are where life on Earth began.
