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...
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...
The University of Massachusetts Dartmouth received a $336,586 Project Grant from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) to conduct collaborative research on deciphering the mechanisms of marine nitrous oxide (N2O) cycling. The research team, which includes one postdoctoral investigator, two graduate students, and several undergraduates, will use stable isotopes, molecular markers, and in-situ rate measurements to study N2O production and consumption in the...
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...
This National Science Foundation Project Grant award, titled "COLLABORATIVE RESEARCH: USING STABLE ISOTOPE LABELING TO TRACE THE FATE OF AMINO ACIDS AND FORMATION OF REFRACTORY DISSOLVED ORGANIC NITROGEN (DON) IN THE OCEAN", was funded under the Geosciences program (CFDA 47.050). The $283,615 award, made to Coastal Carolina University, will investigate how amino acids are transformed into different forms of dissolved organic nitrogen in the ocean. Using stable isotope labeling...
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 $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 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) will provide $452,631 over 3 years to the University of Miami's Rosenstiel School of Marine and Atmospheric Science (RSMAS) for a collaborative research project on using hydrogen isotope analysis of amino acids as a novel tracer of microbial processes in marine particles. The research aims to improve understanding of the formation and sinking of organic particles in the ocean, which is critical...
This $442,689 project grant from the National Science Foundation Division of Ocean Sciences 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. The grantees, led by the University of Connecticut Office of Sponsored Programs, will investigate how phytoplankton access subsurface nitrogen at Station ALOHA in the North Pacific Subtropical Gyre. Researchers will sort phytoplankton...
This National Science Foundation project grant of $328,355 will fund research into nitrogen isotope dynamics on the Amundsen Sea continental margin in Antarctica under the Geosciences program (CFDA 47.050). Trustees of Boston College, doing business as Boston College, will collect full water column profiles of nitrogen and oxygen isotope ratios in nitrate along with isotope ratios of total dissolved nitrogen at select stations during the U.S. GEOTRACES GP17-ANT expedition. Suspended particle...

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 phytoplankton species and changes in nutrient availability or growth conditions independently impact nitrogen isotope values in amino acids. Outcomes include new knowledge about compound-specific and intramolecular nitrogen isotope signatures in polyamine amino acids from key phytoplankton. Insights gained will enable new applications of amino acid isotopic analyses to study topics like the ocean's biological pump and paleoceanography.
