During January and February 2016, I joined a team of scientist aboard the Research Vessel Atlantis on a 40 day expedition to the Pito Deep. This is a unique site in the Pacific Ocean where tectonic plates have exposed the lowermost layers of the ocean crust. We used two underwater robots to map and sample this undersea canyon and even discovered five new hydrothermal vents! You can learn more about the expedition on the website pitodeep.org
