The National Science Foundation (NSF) awarded a $449,462 Project Grant under the Geosciences Program (CFDA 47.050) to the University of South Florida (USF) to study the effects of SUP05 cells and viruses on nitrogen cycling in marine oxygen minimum zones. The project is evaluating how the interactions between SUP05 bacteria and the viruses that infect them impact nitrogen transformations and loss processes in these ocean regions. Through a combination of in situ measurements, DNA/RNA sequencing,...
This $408,738 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to investigate the effects of SUP05 bacterial cells and the viruses that infect them (phages) on nitrogen cycling in marine oxygen minimum zones. The project is led by the University of Washington, and aims to detail the combined impact of SUP05 cells and their associated phages on nitrogen transformation and loss processes in these ocean regions. Through a...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award provides $245,406 to Florida State University (FSU) to study the effects of SUP05 cells and viruses on nitrogen cycling in marine oxygen minimum zones (OMZs). The key products and services to be delivered under this 3-year project include: Through a combination of in situ measurements, DNA/RNA sequencing, and laboratory experiments, the project is evaluating how interactions between SUP05 bacterial cells...
Stanford University was awarded a three-year, $751,285 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will fund research to quantify nitrogen fixation rates of non-cyanobacterial diazotrophs and environmental controls on their activity from April 2021 through March 2024. As part of the Geosciences program's mission to expand fundamental knowledge of the integrated Earth system through basic...
The University of Massachusetts Dartmouth received a $336,586 Project Grant from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) to conduct collaborative research on deciphering the mechanisms of marine nitrous oxide (N2O) cycling. The research team, which includes one postdoctoral investigator, two graduate students, and several undergraduates, will use stable isotopes, molecular markers, and in-situ rate measurements to study N2O production and consumption in the...
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...
The National Science Foundation Division of Ocean Sciences awarded a $776,194 Project Grant to Stanford University from September 2021 through August 2024. The grant supports collaborative research to quantify nitrous oxide sources across an oxygen gradient in the northern Benguela upwelling system off the coast of Namibia and Angola. This research aligns with the Geosciences program's goal of expanding fundamental knowledge and understanding of the integrated Earth system through basic research...
The University of California Santa Cruz will receive $849,702 through August 2024 from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to study microbial control of dissolved organic nitrogen in the ocean. Using new amino acid tracers, the University will conduct research on bacterial sources and cycling of refractory dissolved organic nitrogen. This project grant aims to strengthen fundamental understanding of the integrated...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $205,943 to San Jose State University Research Foundation to characterize Rhizosolenia mat ecosystems and determine if they obtain nitrogen from nitrogen-fixing microbes in the North Pacific Subtropical Gyre. The 3-year project, beginning January 1, 2025, aims to advance understanding of marine nitrogen cycling and the role of these diatom mats in oceanic productivity. The work will combine...
