Cruise Announcement – Hydrothermal Hunt at Mariana

Melissa Anderson, a Ph.D. student in the department of Earth and Environmental Sciences at the University of Ottawa and visiting scholar at the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, has been selected by the Schmidt Ocean Institute to participate in an upcoming research cruise aboard the R/V Falkor.

The cruise is headed to the unexplored Mariana back-arc in the western Pacific, searching for new hydrothermal vent sites using the Sentry Autonomous Underwater Vehicle (AUV) and various instruments to detect optical and chemical changes in the water column that result from hydrothermal discharge at the seafloor.

Melissa will be providing her expertise on geological mapping of the seafloor in order to understand the tectonic controls on the distribution of back-arc volcanism, and the geological controls on hydrothermal venting. The science team expects to find some surprises given how little exploration has been done in the back-arc and anticipates finding several new sites.
