Dr. Kelley takes us a tour of one of the most dynamic environments on Earth - ‘Axial Seamount’. Our window into this world is the Regional Cabled Array, an underwater laboratory that streams live data from over 150 instruments to shore 24/7. Using high definition video from deep-diving remotely operated vehicles, we will explore Axial Seamount, which is the largest and most active volcano off our coast. This volcano erupted in 1998, 2011, and 2015 and is posed to erupt again. Located a nearly a mile beneath the oceans surface, Axial displays an amazing seascape of glass covered collapsed lava lakes with spectacular archways and deep channels where rivers of lava flowed. The heat from molten material within the core of the volcano drives spectacular underwater hot springs emitting boiling fluids and hosting amazing life forms that thrive off of the volcanic gasses.
