Skidaway Institute of Oceanography scientist Aron Stubbins joined a research cruise this summer to study hydrothermal vents, but what his fellow scientists found was a recently erupted undersea volcano.
The Axial Seamount is an undersea volcano located about 250 miles off the Oregon coast and is one of the most active and intensely studied seamounts in the world. What makes the event so intriguing is that Bill Chadwick, an Oregon State University geologist, and Scott Nooner, of Columbia University, had forecast the eruption five years before it happened. Their forecast, published in the Journal of Volcanology and Geothermal Research, was based on a series of seafloor pressure measurements that indicated the volcano was inflating and is the first successful forecast of an undersea volcano.
The discovery of the new eruption came on July 28, when Chadwick, Nooner and their colleagues led an expedition to Axial aboard the R/V Atlantis, operated by the Woods Hole Oceanographic Institution. Using “Jason,” a remotely operated robotic vehicle (ROV), they discovered a new lava flow on the seafloor that was not present a year ago. The expedition was funded by the National Science Foundation and the National Oceanic and Atmospheric Administration (NOAA).
