Our Time Series Studies are focused on Axial Seamount, the most active submarine volcano in the NE Pacific. It rises to a depth of 1400 m below sea level and is located approximately 300 miles off the coast of Oregon. Axial Seamount was the site of the world's first underwater volcano observatory called NeMO and has erupted most recently in 1998 and 2011. Because it is so active, Axial has been chosen as a key node on the new cabled observatory, which is part of the National Science Foundation’s Ocean Observatory Initiative (OOI). Axial continues to be the focus of long-term time-series studies of the interactions between geology, chemistry, and biology on a dynamic part of the mid-ocean ridge system using state-of the art technology.  For more information on our previous work at Axial Seamount go to our Axial Theme page.
