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...
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 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) will provide $419,968 to Texas A&M University-Corpus Christi to conduct research on dissolved organic sulfur (DOS) in the Pacific and Atlantic Oceans. The research aims to: 1) quantify the DOS inventory across the Pacific Ocean, 2) identify abiotic and biotic processes responsible for DOS production and removal, and 3) investigate the reactivity of DOS components through monthly sampling at...
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 $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 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...
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 Project Grant award of $645,614 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research effort to examine the biogeochemistry of dissolved organic sulfur (DOS) in the Pacific Ocean. The research objectives are to: 1) quantify the DOS inventory across the Pacific, 2) identify the processes governing DOS production and removal, and 3) investigate the reactivity of DOS over a year-long monthly sampling period near Bermuda. The project will...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) totaling $257,498 will support research to characterize Rhizosolenia mat ecosystems and determine whether they obtain nitrogen from nitrogen-fixing microbes in the North Pacific Subtropical Gyre. The project, led by researchers at Stanford University, aims to provide the first detailed characterization of mat-forming Rhizosolenia diatoms and their associated diazotroph communities using a...
