- This $745,396 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project investigating the nutritional ecology of diverse marine phytoplankton communities. The research aims to develop novel genomic tools to diagnose the nutritional state of various phytoplankton species and map nutrient stress patterns across global ocean regions. The project leverages a funded ocean research cruise and combines comparative...
- 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 $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...
- 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...
- This three-year project grant from the National Science Foundation's Geosciences program, totaling $739,133, supports collaborative research on sources and transformations of export production from coral and plankton bioarchives. The University of Rhode Island will receive funding through February 2024 to conduct a novel 50-year record of pelagic-benthic coupling by analyzing coral and plankton samples. The Geosciences program aims to expand fundamental knowledge of the integrated Earth system...
- This National Science Foundation Project Grant of $597,248 supports research into applying novel approaches to link microbial growth efficiency, function, and energy transfer in the ocean. Funded under the Geosciences program (CFDA 47.050), the award will further understanding of the integrated Earth system through basic research in ocean sciences. Specifically, the University of Miami Rosenstiel School of Marine and Atmospheric Science will conduct research from September 2023 to August 2026 to...
This Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $367,277 to the University of Maryland Center for Environmental Science to study the ecological and biogeochemical role of Rhizaria in the oligotrophic ocean from August 2023 through July 2026. Key products include greatly improved estimates of total Rhizaria biomass in low-nutrient ocean gyres, novel measurements of Rhizaria vertical distribution and environmental niche characteristics, identification of environmental drivers of seasonal and spatial Rhizaria population variation, and a model-based estimate of Rhizaria contributions to vertical nutrient flux into the deep ocean. Researchers will utilize a combination of sampling methods and cutting-edge in situ imaging to bypass limitations and accurately estimate Rhizaria biomass across a wide depth range and monthly intervals. Generated data will be incorporated into a model of carbon and nutrient transfer into the deep ocean.
