Summary
Reverse weathering is a chemical process that forms clay minerals from dissolved silica and positively charged ions in marine sediments. This process is important because it impacts ocean pH, the availability of important metals (e.g. iron, lithium), and the long-term carbon cycle. In this project, the researchers plan to use stable and radioactive silicon isotopes to track reverse weathering processes in sediments of the Mississippi River Plume. The research includes laboratory and ship-based experiments exploring the role of microbial activity in sediment silicon cycling and reverse weatheri
