I lead the USGS Global Marine Minerals project, which you can learn more about here. My work focuses on the geochemistry of marine minerals including all aspects of water-rock interactions such as precipitation, alteration, and the role of nanoparticles in mineral accumulation.
Mineral-laden water emerging from a hydrothermal vent on the Niua underwater volcano in the Lau Basin, southwest Pacific Ocean. As the water cools, minerals precipitate to form tower-like “chimneys.” Image taken during 2016 cruise “Virtual Vents.”
