This $283,615 federal Project Grant awarded by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) supports research to investigate the fate of amino acids and the formation of refractory dissolved organic nitrogen (DON) in the ocean. The project uses stable isotope labeling techniques to trace the conversion of amino acids into inorganic forms, labile DON, and refractory DON in waters ranging from productive coastal zones to oligotrophic open ocean environments. Advanced...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $126,324 to Texas A&M University, with a project period from July 2024 to June 2027, will support research to determine the role of dissolved organic nitrogen (DON) in sustaining biological productivity in the nutrient-poor subtropical North Pacific Ocean. The key activities under this award include: conducting a one-month research expedition in the North Pacific to study DON production,...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $237,316 to Pomona College to conduct collaborative research on the role of dissolved organic nitrogen (DON) in sustaining biological productivity in the subtropical North Pacific Ocean. The research aims to quantify the contribution of allochthonous (externally derived) DON to meeting the nitrogen demand of these "ocean desert" ecosystems. Over the 3-year project period from...
This National Science Foundation (NSF) Geosciences program Project Grant (CFDA 47.050) awarded to the University of New Hampshire (UNH) provides $155,302 to support collaborative research on the contribution of allochthonous (externally-derived) dissolved organic nitrogen (DON) to biological nitrogen demand in the subtropical North Pacific Ocean. The research expedition will depart from San Diego, CA and end in Honolulu, HI to study the production, accumulation, chemical composition, and...
This Project Grant award from the National Science Foundation (NSF) Geosciences program (CFDA 47.050) provides $107,673 to the Regents of the University of Minnesota to study the role of dissolved organic nitrogen (DON) in sustaining biological productivity in the oligotrophic subtropical North Pacific Ocean. The award will fund a one-month research expedition from San Diego, CA to Honolulu, HI to collect observations on DON concentration, composition, and utilization by marine microbes. The...
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...
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 federal Project Grant award in the amount of $250,766 was provided by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050). The award, titled "CAREER: CONSTRAINING ATMOSPHERIC NITRATE PRECURSORS AND CHEMISTRY ACROSS THE UNITED STATES (US)", aims to improve the prediction of atmospheric nitrate formation by focusing on nitrogen oxide precursor emissions and oxidation pathways. The project will utilize isotope observations from national monitoring sites,...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $199,997 Project Grant to The Research Foundation For The State University Of New York, doing business as Suny ESF, under the NSF Geosciences federal grant program (CFDA 47.050) with a period of performance from July 1, 2023 to June 30, 2024. The grant is supporting a RAPID project to characterize the sources and chemistry of nitrogen oxides, nitrous acid, and particulate nitrate during the AEROMMA...
The University of New Hampshire will receive $260,000 in funding from the National Science Foundation Division of Environmental Biology through the Biological Sciences federal grant program (CFDA 47.074) from September 1, 2021 to August 31, 2024. The funding will support collaborative research examining mineral-associated organic matter as an overlooked source and mediator of bioavailable nitrogen. The research aims to advance understanding of major problems confronting the nation in the...
