EOI scientists participated in several ROV dives remotely via "telepresence" during the 2016 Deepwater Exploration of the Marianas expedition by the NOAA ship Okeanos Explorer.  During Leg 1 of the expedition, EOI co-led three dives in the Mariana backarc, exploring the site of a recent eruption  and two newly discovered hydrothermal vent fields. All of these discovered during a recent cruise on R/V Falkor in Nov-Dec 2015, and set the stage for further exploration during a follow-on R/V Falkor cruise in December 2016.  During Leg 3 of the Okeanos expedition, EOI co-led three dives in at three volcanically active seamounts, each with its own unique ecosystem.  The expedition was supported by the NOAA Ocean Exploration and Research Program.
