A research vessel packed with teams of scientists recently returned from a two week journey to study an active volcano off the Oregon coast. The volcano, called Axial Seamount, lies more than a mile beneath the surface of the ocean, about 250 miles west of Cannon Beach. It may be one of the most well studied volcanoes in the world. Among other things, the scientists were trying to learn how to predict when volcanoes might erupt. OPB science reporter Jes Burns was also aboard the research vessel, and tells us about the journey, and the science that happened onboard.
