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...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will support collaborative research at the California Institute of Technology (Caltech) and the University of Miami. The $569,967 award, effective March 1, 2025 through February 29, 2028, will fund the development of a novel tracer using hydrogen isotopes in amino acids to study microbial processes and the formation and sinking of organic particles in the ocean. The research aims to advance...
This $309,557 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research effort to study the fate of amino acids and the formation of refractory dissolved organic nitrogen (DON) in the ocean. Using stable isotope labeling techniques, the project will trace how amino acids are converted to different nitrogen forms, including remineralization into inorganic compounds, conversion to labile DON, and transformation to refractory DON....
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 award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research study conducted by Coastal Carolina University to investigate the fate of amino acids and the formation of refractory dissolved organic nitrogen (DON) in the ocean. Using stable isotope labeling techniques, the study will trace the conversion of amino acids into different nitrogen compounds, including remineralized inorganic forms and refractory DON that can persist...
This $452,631 Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) supports a collaborative research project to investigate the use of hydrogen isotope analysis of amino acids as a novel tracer of microbial processes in marine particles. The project, conducted by researchers at the University of Miami's Rosenstiel School of Marine and Atmospheric Science (RSMAS), aims to improve understanding of the formation and sinking of organic particles in the...
This $419,968 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to examine the biogeochemistry of dissolved organic sulfur (DOS) in the Pacific Ocean. The research will quantify the DOS inventory across the Pacific, identify abiotic and biotic processes governing DOS production and removal, and investigate the reactivity of DOS over a one-year period at the Bermuda-Atlantic Time Series site. The project will...
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...
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...
