- 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...
- Federal Grant Award Summary The National Science Foundation's Division of Ocean Sciences awarded a $350,000 Project Grant (CFDA 47.050, Geosciences Program) to Bigelow Laboratory for Ocean Sciences effective September 1, 2025, through August 31, 2028. The award supports fundamental research investigating the life-history patterns, systematics, and biogeography of Patescibacteria and Chloroflexota—abundant yet understudied bacterial lineages residing in marine sediments. The primary...
- This National Science Foundation (NSF) Award under the Geosciences Program (CFDA 47.050) supports fundamental research to characterize the physiological and environmental cycling of abundant osmolytes, which are small carbon-containing molecules produced by marine microorganisms. The $519,767 award to the University of North Carolina at Wilmington aims to quantify how environmental conditions, such as nutrient availability and temperature, impact the abundances and cycling rates of these...
- The National Science Foundation Division of Ocean Sciences awarded a $260,366 Project Grant to the University of Washington's Office of Sponsored Programs to support collaborative research under the Geosciences program (CFDA 47.050). The research aims to conduct shipboard measurements of dissolved aluminum, iron, and manganese to trace inputs to the South Pacific Gyre and Southern Ocean from September 2021 through August 2024. The Geosciences program seeks to expand fundamental knowledge of...
- 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...
- Federal Grant Award Summary The National Science Foundation's Division of Ocean Sciences has awarded the University of Arizona $391,271 under the Geosciences program (CFDA 47.050) for a collaborative research project spanning September 1, 2025, through August 31, 2028. The project will produce high-resolution paleoclimate reconstructions and oceanographic datasets derived from marine sediment cores collected from the Garrison Basin offshore Texas. Specifically, the research will generate...
- Federal Project Grant Award Summary The National Science Foundation's Division of Ocean Sciences awarded $745,396 to the University of California, Irvine under the Geosciences program (CFDA 47.050) for a collaborative research initiative examining large-scale nutritional ecology of diverse phytoplankton. The project, which commenced September 1, 2025 and concludes August 31, 2028, delivers innovative genomic tools and methodologies to diagnose nutritional stress conditions in marine...
The National Science Foundation Division of Ocean Sciences awarded $421,600 under the Geosciences federal grant program (CFDA 47.050) to the University of Arizona for the period April 1, 2023 through March 31, 2026. The award will support research into polyphosphate production and cycling in marine ecosystems. Specifically, the university researchers will conduct the first quantitative measurements of polyphosphate in marine microorganisms through laboratory and field studies. They will examine polyphosphate content and chain length distribution across different microbial groups and environmental conditions with varying phosphorus availability in the Pacific Ocean and Mediterranean Sea. The researchers also aim to clarify the cellular function and role of polyphosphate in microbial phosphorus nutrition through analyses of production, demand, and stoichiometry. Outcomes of this research will further understanding of phosphorus biogeochemistry and its influence on ocean productivity, carbon uptake, and climate regulation.
