This Project Grant award of $459,803 from the National Science Foundation's Biological Sciences program (CFDA 47.074) supports a collaborative research project titled "ULTRA-DATA: Developing Global Riverine Solute Regime and Synchrony Frameworks for Understanding Watershed-Scale Controls on River Biogeochemical Signals." The goal of this 3-year project is to better understand and predict changes in river chemistry at a global scale. The research team will (re)use publicly available...
This $211,792 federal Project Grant awarded by the National Science Foundation (NSF) Geosciences program supports research to improve models of river chemistry and the global alkalinity cycle. The project, titled "BALANCING THE GLOBAL ALKALINITY CYCLE BY IMPROVING MODELS OF RIVER CHEMISTRY," is being conducted by William Marsh Rice University in Houston, Texas. The research aims to develop new analysis approaches to separate the effects of flow paths and flow rates on river water...
This $372,598 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to incorporate stream biogeochemistry into carbon assessment models for enhanced rock weathering, a carbon dioxide removal approach. The project aims to add biological processes like photosynthesis and respiration into a dynamic river network model to better quantify the fate of bicarbonate generated through enhanced rock weathering. This will help identify river...
This National Science Foundation Project Grant award of $856,624 provides funding from January 2023 through December 2025 to support research entitled "Continental-Scale Determinants of Stream Solute Spatial and Temporal Patterns." The award is made under the Geosciences program (CFDA 47.050) to support basic research in the atmospheric, earth, and ocean sciences. Specifically, the University of Florida will leverage a continental-scale dataset across the eastern United States to...
The National Science Foundation (NSF) awarded a $250,000 Project Grant under the Computer and Information Science and Engineering (CFDA 47.070) program to the University of Virginia. The grant supports the development of new physics-guided graph network models to capture complex, non-stationary, and poorly observed water dynamics in freshwater ecosystems. Key innovations include new graph-based architectures, continual learning strategies, and model initialization methods that leverage...
This $2.9 million project grant from the National Science Foundation's Division of Emerging Frontiers will fund research from 2023 to 2027 under the Biological Sciences program (CFDA 47.074). Oregon State University will lead a collaborative effort to study the resilience of freshwater ecosystems under changing climate conditions. Researchers will test how biodiversity and individual variation among species affect an ecosystem's ability to withstand environmental changes. They will conduct...
The National Science Foundation awarded a $254,976 Project Grant to Resbonds International Corporation through the Engineering program (CFDA 47.041) to develop a digital platform for assessing water quality at urban-watershed interfaces. The platform will integrate physical data from advanced monitoring systems with artificial intelligence to serve as a scalable analytics platform using environmental, economic, and social data. It aims to help cities and utilities finance infrastructure projects...
This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...
This $550,000 federal Project Grant award was provided by the National Science Foundation (NSF) under the Technology, Innovation, and Partnerships (CFDA 47.084) program. The grant supports the development of a new monitoring system designed to more accurately measure streamflow in rivers and streams. The project aims to address the limitations of current monitoring methods by using advanced instruments and modern communication technology to enhance understanding of river systems and provide more...
The National Science Foundation (NSF) awarded a $523,014 Project Grant under the Geosciences program (CFDA 47.050) to the University of Massachusetts (UMass) to develop computational models of global carbon dioxide (CO2) fluxes from inland waters. The research aims to provide robust, physically-constrained estimates of CO2 emissions from rivers, streams, lakes, and reservoirs by coupling hydrologic and hydraulic routing systems with a stream network CO2 model. The project will validate the...
