Sarah Moriarty is a PhD candidate at Memorial University of Newfoundland. Sarah utilizes stable isotopes as a tool to constrain sub-seafloor fluid/rock interactions affecting hydrothermal fluid cycling and associated seafloor massive sulfide deposit formation at submarine hydrothermal vent sites from various geological settings. Previously she received her M.Sc. in Earth Sciences from Memorial, as well as a dual B.Sc. in Geology and Oceanography at Kutztown University of Pennsylvania.
