Lecture date: March 25, 2014. Dan Fornari is a senior scientist in geology and geophysics at the Woods Hole Oceanographic Institution.

The largest and most active volcanic province on Earth lies beneath the ocean along the global Mid-Ocean Ridge. Research on individual eruptions is still in its infancy. The close association of deep-sea hydrothermal vents and their chemosynthetic-based biological communities has revolutionized biological and oceanographic science, but there is much that we still do not understand about these linked phenomena.

Fornari presented examples of the lava formations and hydrothermal vent features that have been imaged using the latest deep-sea photographic and lighting techniques deployed on state-of-the-art vehicles.
