Julie is an oceanographer working to advance knowledge of the deep ocean. She is interested in how basic earth processes- rocks forming, fluids moving, sediments accumulating- interact to create and maintain microbial life in the deepest and darkest parts of the ocean. She has led and participated in ocean expeditions around the world using deep submergence technology. She also enjoys mentoring the next generation of scientist and communicating their work to the public.

Chris is a marine geochemist whose primary research focuses on seafloor fluid flow (hydrothermal vents and seeps): Why do they occur where they do? What are their impacts on global-scale ocean biogeochemistry? What are the best ways to explore them using advanced technologies? By studying the deep ocean on Earth, he’s able to investigate newly discovered ocean worlds in the outer solar system.
