Several hundred miles off the coast of Oregon and Washington, there’s an undersea volcano known as Axial Seamount. Thanks to a set of high-tech instruments installed last summer by a team of scientists, many from the College of the Environment, the deep sea is online and oceanographers were able to observe an eruption of the Axial Volcano in April 2015. PBS NewsHour’s Hari Sreenivasan recently spoke with the School of Oceanography‘s John Delaney and Debbie Kelley about their team’s deep sea observatory, including a network of sensors, moorings, and cameras that collect troves of new information about this underwater world.
