This Project Grant award, worth $905,118, was provided by the National Science Foundation Division of Polar Programs under CFDA Program 47.078 to the University of Rhode Island Research Office. The funding will support a collaborative research project examining how the chemistry of fossil diatoms (a type of plankton) can be used as proxies to reconstruct past changes in ocean nutrients and biological productivity, which are linked to global climate change. The research will involve field...
This $257,498 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) is funding a 3-year research project at The Leland Stanford Junior University to characterize Rhizosolenia diatom mats and their associated nitrogen-fixing microbes in the North Pacific Subtropical Gyre. The project aims to determine if these diatom mats obtain nitrogen from symbiotic diazotrophs, which could transform the understanding of their role in oceanic nitrogen and carbon...
This $713,951 Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) supports research into the adaptability of phytoplankton carbon dioxide concentrating mechanisms to changing climatic conditions. The grant to Columbia University will fund experiments to quantify the plastic and adaptive responses of carbon fixation in five key phytoplankton groups - diatoms, dinoflagellates, green algae, coccolithophores, and cyanobacteria - under climate change...
This National Science Foundation project grant award of $1,053,775 provides funding from June 1, 2023 through May 31, 2026 to support research examining the cellular metabolism and physiology of diatom-diazotroph associations (DDAs) and evaluate their ecosystem and biogeochemical impacts. The University of Rhode Island will investigate the responses of DDAs to different nitrogen sources and temperatures, compare DDA physiology and metabolism to asymbiotic diatoms, and model ecosystem-level...
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...
This $916,578 federal Project Grant awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) supports fundamental research to expand understanding of iron adaptation in marine phytoplankton across global oceans. The key objectives are to: Characterize iron storage capacities and limitation thresholds for 20 Synechococcus phytoplankton strains from 11 ecotypes across a range of ocean iron niches. Analyze gene regulation responses to varying iron availability for the 20...
The National Science Foundation awarded a $1,101,964 project grant to the Institute For Systems Biology under the Biological Sciences program (CFDA 47.074) for research titled "COLLABORATIVE RESEARCH: IMAGINE: QUANTIFYING DIATOM RESILIENCE IN AN ACIDIFIED OCEAN." The grant, awarded June 15, 2021 with a completion date of May 31, 2024, will fund research to increase scientific understanding of how diatom populations respond and adapt to increasing ocean acidification. The Biological...
This $224,928 three-year Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will fund collaborative research on adaptations of Southern Ocean diatoms to manganese scarcity. The University of Georgia Research Foundation will support two early career scientists and one female Earth scientist to conduct culture experiments on three Antarctic and one temperate diatom species. Using physiological,...
The University of Southern California was awarded a $338,202 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to develop transcriptomics as a tool to investigate toxic diatom responses to ocean heatwave and upwelling events from January 1, 2022 to December 31, 2024. The Geosciences program supports basic research in the atmospheric, earth, and ocean sciences to strengthen understanding of the integrated...
This Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) provides $109,669 to the University of Rhode Island to investigate the relationship between gene expression, silicification, and nitrogen isotopes in diatom species from the Southern Ocean. The award period runs from June 1, 2025 to May 31, 2026. The key objectives are to evaluate how environmental conditions, particularly nitrogen and silicon availability, impact diatom gene expression,...
