Dr. John Jamieson

Associate Professor;
Canada Research Chair in Marine Geology (Tier II);
Chair, Canadian Consortium for Ocean Drilling

I received my BSc (Hons) from the University of Alberta (2002), MSc from the University of Maryland (2005), and PhD from the University of Ottawa (2013). From 2013-2015 I worked as a research scientist at GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany).

Dr. Chris Galley

Post-doctoral Fellow; PhD 2022

I received my B.Sc. from the University of Victoria in 2015, and Ph.D. from Memorial University of Newfoundland in 2022. I study ancient and modern hydrothermal systems to better understand the fundamental geologic controls on ore-forming processes, primarily through the modelling of geophysical data, where magnetic and/or gravity data to construct 3D physical property models of the Earth.

Sarah Moriarty

PhD Candidate

I received a dual BSc in Geology and Marine Science/Oceanography from Kutztown University of Pennsylvania in 2017 and a MSc in Earth Sciences from Memorial University in 2020. My research focuses on the application of stable isotope signatures (including multiple S and Sr isotopes) of seafloor massive sulfide deposits, hydrothermal fluids, crustal rocks, and sediments to investigate fluid mixing and elemental cycling associated with submarine hydrothermal systems at mid-ocean ridges and arc volcanoes.

Caroline Gini

PhD Candidate

I obtained my Bachelor’s degree in geology from the Université de Lausanne (Switzerland) in 2015 and my Master’s degree in 2017 from the Institut de Physique du Globe de Paris (France). I am interested in understanding geological and tectonic processes at mid-ocean ridges and their implications for hydrothermal systems. My research focuses on understanding the geology of a hydrothermal vent field on the Mohns Ridge, in the Greenland Sea, and geological characterization of the seafloor and exploration of hydrothermal deposits using Interferometric Synthetic Aperture Sonar (InSAS), an ultra-high-resolution underwater acoustic mapping and imaging technology.

Johannes Scheffler

PhD Candidate

I received my B.Sc. in Chemistry at Leipzig University, Germany, in 2017. As part of my M.Sc in Mineralogy and Materials Science at Leipzig I spent an exchange semester at the University of Bergen, Norway, where I had my first experience studying seafloor hydrothermal systems research. My Ph.D. research at MUN focuses on the development and application of different U-series radioisotope geochronological dating methods for submarine hydrothermal systems, starting with samples collected from the Escanaba Trough.

Natalie McNeil

MSc Candidate

I graduated from Saint Mary’s University in Halifax, Nova Scotia, with a BSc (Hons) in geology. At Memorial University my research focuses on the application of the ²³⁰Th/²³⁴U dating technique to samples collected from seafloor hydrothermal vent fields, and evaluating the precision of this technique relative to other techniques that have been applied to vent fields previously (e.g., ²²⁶Ra/Ba).

Kallie Stone

MEnv Candidate

The goal of my research project is to investigate the release of metals into the ocean from the oxidation of seafloor massive sulfide deposits. For my undergraduate thesis project, I evaluated hydrothermal discharge velocities associated with active venting at the Niua South hydrothermal vent field (near Tonga) through video analysis, and used these data to calculate the chemical mass balance and depositional efficiency of this hydrothermal system.

Charles Lapointe

MSc Candidate

I earned a B.Sc. in Earth & Planetary Sciences from McGill University in 2022. My M.Sc. project at Memorial University focuses on the geological characterization of the Aurora vent field, located on the Gakkel mid-ocean ridge in the Arctic Ocean. To this end, I am applying a variety of mineralogical, geochemical, and geochronological tools to rock samples collected from the seafloor.
