Treading Water

October 27, 2015

The autonomous underwater vehicle Sentry awaits recovery during the MESH (Mapping, Exploration, Sampling at Havre) research cruise in the spring of 2015. Capable of diving and surveying the seafloor at depths of 6,000 meters, Sentry was an invaluable tool for investigating the Havre volcano, which in 2012 became the largest recorded submarine explosive eruption in history. Working in tandem with the remotely operated vehicle Jason, WHOI scientists Adam Soule, Dan Fornari, and MIT/WHOI Joint Program student Meghan Jones joined an international team of researchers to map the eruption site and sample pumice, marine life, and sediment to better understand undersea volcanoes.(Photo by Dan Fornari, Woods Hole Oceanographic Institution)
