- This National Science Foundation (NSF) project grant, awarded under the Biological Sciences program (CFDA 47.074), provides $163,362 from January 1, 2024 to December 31, 2026 to Duke University to conduct collaborative research. The project aims to determine the relationship between microbial genes and ecosystem processes in order to improve biogeochemical models for nutrient management in water systems like the Chesapeake Bay and wastewater treatment plants. Specifically, the research will...
- 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 Project Grant award from the National Science Foundation's (NSF) Biological Sciences program (CFDA 47.074) provides $491,409 to President & Trustees of Williams College to conduct research on how nitrogen fertilization impacts soil carbon formation and cycling in northern deciduous forests. The key products and services to be delivered include: Leveraging a field experiment to investigate the biogeochemical mechanisms underlying soil carbon responses to nitrogen enrichment across...
This Project Grant from the National Science Foundation Division of Earth Sciences, under the Geosciences program (CFDA 47.050), provides $499,696 to the Stroud Water Research Center Inc. to conduct collaborative research on nitrogen pollution removal processes in riparian soils and wetlands. Specifically, the award will fund an innovative study from July 2022 to June 2025 to identify the key soil conditions that regulate the balance between dissimilatory nitrate reduction to ammonium (DNRA) and denitrification in anoxic soils. The research will evaluate hypotheses around how hydrologic stagnation, specific electron donor to nitrate ratios, and salinization impact the DNRA-denitrification dynamics and ammonium-N production. The work will integrate designed mesocosm experiments using 15N-labeled nitrate, in-situ measurements at mill dam study sites, microbial gene quantification, and reactive transport modeling to advance understanding of nitrogen pollution in landscapes subject to various stressors. Outcomes aim to inform watershed management and environmental decision-making regarding riparian zone functions. The funding also supports graduate student and scientist professional development.
