EOI Scientists Return to Axial Seamount

The 2017 expedition to Axial Seamount was on R/V Revelle, July 13-23, with ROV Jason and AUV Sentry on board. On this expedition we made measurements to monitor the continued re-inflation of the volcano since its last eruption in 2015 so we can better understand how magma is supplied and stored within the volcano, how it fuels hydrothermal vents and their biological communities, and how we can refine forecasts of future eruptions.  We also sampled hydrothermal vents to continue a time-series aimed and understanding the interactions between volcanic events and the hydrothermal and biological systems.  A cruise report is in preparation and will be posted here when it is finished.
