This federal Project Grant award of $309,557.00 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to trace the fate of amino acids and the formation of refractory dissolved organic nitrogen (DON) in the ocean. The study will use stable isotope probing with 15N-labeled amino acids and controlled incubations to investigate how different amino acids are remineralized, converted to labile DON, or transformed into refractory DON. Advanced mass...
The National Science Foundation Division of Ocean Sciences awarded a $438,331 project grant to the University of Massachusetts Dartmouth under the Geosciences program (CFDA 47.050) to conduct collaborative research from April 1, 2023 through March 31, 2026. The research aims to characterize amino acid nitrogen isotopes in phytoplankton and advance understanding of isotopic patterns produced under varying physiological conditions. Investigators and students will explore how different...
The National Science Foundation (NSF) awarded a $237,316 Project Grant under the Geosciences program (CFDA 47.050) to Pomona College for a collaborative research project titled "Contribution of Allochthonous DON to Biological Nitrogen Demand in the Subtropical North Pacific." The project aims to determine the role of laterally transported dissolved organic nitrogen (DON) in sustaining biological productivity in the nutrient-limited subtropical North Pacific Ocean. The one-month...
This three-year, $445,124 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research on the phylogenetic and physiological characterization of amino acid nitrogen isotopes in phytoplankton. The research will examine whether different phytoplankton species produce distinct amino acid nitrogen isotope patterns when using the same nitrogen source. It will also study whether these patterns change under different growth and environmental...
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 award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $126,324 to Texas A&M University to conduct research on the contribution of allochthonous 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 utilization of DON and link it to photosynthesis...
The National Science Foundation Division of Ocean Sciences awarded a $131,201 Project Grant to the University of California Santa Cruz (UCSC) under the Geosciences program (CFDA 47.050) to investigate and develop compound-specific isotope analysis of amino acids (CSI-AA) to better understand the species-level ecology of planktonic foraminifera. The goal is to use CSI-AA from shell-bound organics to refine inferences about foraminifera's depth habitat, diet, and symbiosis in order to improve...
This Project Grant, awarded by the National Science Foundation under its Geosciences program (CFDA 47.050), aims to provide a thorough characterization of the dissolved organic matter (DOM) released by marine nitrifiers. The $300,785 award, effective December 1, 2024 through November 30, 2026, will support laboratory culturing and incubation studies, as well as field experiments, to determine the chemical composition, quantity, release mechanisms, and bioavailability of nitrifier-derived DOM....
This federal Project Grant award for $519,767, provided by the National Science Foundation's (NSF) Geosciences program (CFDA 47.050), supports a collaborative research project to characterize the physiological and environmental cycling of abundant osmolytes in the ocean. The primary objectives are to: Identify differential production of osmolytes by different microbial taxa in response to nitrogen stress, Measure rates of osmolyte assimilation and metabolic fate, and Quantify osmolyte cycling...
The University of Maryland Center for Environmental Science will receive $498,844 from the National Science Foundation under the Geosciences program (CFDA 47.050) to conduct collaborative research from April 1, 2023 through March 31, 2026. The research aims to characterize amino acid nitrogen isotopes in phytoplankton and advance understanding of isotope patterns produced under varying physiological conditions. Researchers will examine whether different phytoplankton species and the same species...
