- This National Science Foundation Project Grant under the Geosciences Program (CFDA 47.050) provides $734,947 in funding to the University of Rhode Island to conduct collaborative research on the life cycle of phytoplankton blooms in coastal ecosystems. The research team will analyze a unique set of samples and data collected in 2021-2022 to better understand the metabolic, functional, and taxonomic interactions between phytoplankton and associated bacteria that influence the timing and...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $373,910 to San Jose State University Research Foundation to investigate whether Rhizosolenia diatom mats in the North Pacific Subtropical Gyre obtain nitrogen from symbiotic nitrogen-fixing microbes. The research aims to better understand the role of these fragile, understudied diatom mats in oceanic productivity and carbon cycling. The award began on January 1, 2025 and is scheduled for...
- The National Science Foundation Division of Ocean Sciences awarded a $720,779 project grant to the Bermuda Institute of Ocean Sciences, Inc. (BIOS) to support collaborative research from September 2021 through August 2024. The research aims to investigate eddy impacts on coastal carbon chemistry and coral calcification in situ and through historical analysis. This work will advance understanding of the integrated Earth system, as outlined in the objectives of the Geosciences program (CFDA...
- 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...
- The University of California, Santa Cruz received a $721,442 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) to investigate whether the diatom species Rhizosolenia obtain nitrogen, a key nutrient, from symbiotic nitrogen-fixing microbes. This research aims to better understand the role of fragile Rhizosolenia mats in marine ecosystems and their contribution to ocean productivity, as traditional sampling methods often miss these microbial communities. The...
- This Project Grant award of $100,000.00 from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support research led by the University of Puerto Rico's Research and Development Center to investigate symbiotic relationships between ciliates, bacteria, and archaea in marine oxygen-depleted environments. The study aims to identify the role of these microbial consortia in increasingly prevalent ocean "dead zones" and shed light on their metabolic adaptations and...
- 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 $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 National Science Foundation Project Grant award of $456,170 under the Geosciences program (CFDA 47.050) will fund research into the ecological and biogeochemical role of Rhizaria in the oligotrophic ocean. The award was made on August 15, 2023 to the Bermuda Institute of Ocean Sciences, Inc. for work to be completed by July 31, 2026. Under this award, the awardee will conduct sampling and analysis of Rhizaria populations across depths of 0-1200 meters at the Bermuda Atlantic Time-series Study site on a monthly basis. Using a combination of sampling methods including Niskin bottles, particle gel traps, nets and an underwater vision profiler, the team will generate improved estimates of total Rhizaria biomass, measure vertical distributions and environmental niche characteristics, and identify seasonal variations and environmental drivers of Rhizaria communities. Molecular identification, imaging, and individual organism barcoding will be combined with the sampling data. Elemental analyses and biomass estimates will then be incorporated into a model of Rhizaria contributions to vertical carbon and nutrient flux in the oligotrophic ocean. The research aims to enhance understanding of nutrient movement and impacts on biogeochemical cycles under changing conditions.
