This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $372,598 to the University of Washington supports the incorporation of stream biogeochemistry into carbon assessments of enhanced rock weathering (ERW), a promising carbon dioxide removal approach.
The project aims to add photosynthesis and respiration processes of aquatic plants and algae into a dynamic river network model to identify river conditions that promote biological uptake and subsequent release of ERW-derived carbon back to the atmosphere. This will help determine if it is possible to manage rivers and watersheds to maximize carbon dioxide removal by ERW. The open-source model developed through this mid-career advancement award, running from September 2024 to August 2027, will directly inform future ERW deployments.
