Project Grant 2525151
- This federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $309,557 to the University of Texas at Austin to investigate the fate of nitrogen in amino acids and the formation of refractory dissolved organic nitrogen (DON) in the ocean. The project will use stable isotope probing with 15N-labeled amino acids to trace the pathways by which amino acid-derived nitrogen is remineralized, converted to labile DON, or transformed to refractory...
- The University of California Santa Cruz received a three-year, $543,521 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will fund collaborative research to quantify nitrogen fixation rates of non-cyanobacterial diazotrophs and determine environmental controls on their activity. As part of the Geosciences program's goal of expanding knowledge of the integrated Earth system through basic research,...
- 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 $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...
- 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...
- This $283,615 Project Grant award from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) will fund a collaborative research project led by Coastal Carolina University to investigate the fate of nitrogen in amino acids and the processes that contribute to 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 trace the fate of different amino acids as...
- The National Science Foundation Division of Ocean Sciences awarded a $100,590 project grant to Texas A&M University on June 15, 2021 with a completion date of May 31, 2022. The grant was awarded under the Geosciences program (CFDA 47.050) to support the acquisition of an auto analyzer system for nutrient analysis at sea. The auto analyzer system will allow Texas A&M researchers to analyze seawater samples for nutrient content as part of basic research efforts to expand understanding of...
- This $582,005 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by The Trustees of Princeton University to investigate nitrous oxide (N2O) consumption in the surface ocean. The research aims to determine the factors that control or stimulate N2O reduction in surface waters and characterize the microbes responsible for the process. Specifically, the investigators will perform 15N tracer incubations to measure the rate of N2O reduction...
- This $297,369 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund research evaluating the contribution of small eukaryotes to nitrate-based new production in the North Pacific Subtropical Gyre. Over a three-year period ending November 2025, the University of Hawaii at Manoa will conduct laboratory and ship-based research to better understand how phytoplankton access subsurface nitrogen in surface waters during summer months. Researchers will sort phytoplankton...
- Stanford University was awarded a three-year, $751,285 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will fund research to quantify nitrogen fixation rates of non-cyanobacterial diazotrophs and environmental controls on their activity from April 2021 through March 2024. As part of the Geosciences program's mission to expand fundamental knowledge of the integrated Earth system through basic...
The National Science Foundation's Geosciences Program (CFDA 47.050) awarded a Project Grant of $498,457.00 to Texas A&M University to conduct research on the rates and fates of nitrogen fixation in the Southwest Pacific. The research aims to track the fate of newly fixed nitrogen using geochemical tools, in collaboration with French scientists. Specifically, the study will examine whether the newly fixed nitrogen is retained in the surface ocean or sinks to the deep ocean, and how this fate may change depending on which microbes carry out the nitrogen fixation process. The project will support a graduate student, undergraduate student, and technician, and train them in cutting-edge biogeochemical techniques. The award has an ultimate completion date of July 31, 2028.
