This $499,806 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research to better understand the interconnected oceanic cycles of iron and carbon. The award, made to Bigelow Laboratory for Ocean Sciences, will integrate field observations, experimental studies, and ocean biogeochemical modeling to examine the "colloidal shunt" mechanism, whereby dissolved iron interacts with dissolved and particulate organic matter....
This $197,103 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research between U.S. and U.K. scientists to better understand the linkages between iron and organic carbon cycles in the ocean. The research will integrate field observations from the Bermuda Atlantic Time-series Study and Cape Verde Ocean Observatory regions with targeted experimental studies and ocean biogeochemical modeling. The project aims to...
This $369,916 Project Grant award from the National Science Foundation's (NSF) Division of Ocean Sciences (Geosciences CFDA #47.050) supports collaborative research on the ocean iron cycle and its relationship to the carbon cycle. Researchers from the University of South Florida and the University of Hawaii will measure iron isotopes in seawater samples from three Pacific Ocean GEOTRACES expeditions. This data will be used in biogeochemical modeling to address key questions about iron...
This $540,281 Project Grant, awarded by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050), supports a collaborative research effort to better understand the linkages between the oceanic cycles of iron and carbon. Led by the Old Dominion University Research Foundation (ODURF), the project will integrate field observations from the Bermuda Atlantic Time-series Study (BATS) and Cape Verde Ocean Observatory regions with targeted experimental studies and ocean...
This $562,895 Project Grant award from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) supports collaborative research to better understand the linkages between the oceanic cycles of iron and organic carbon. The research, conducted by a team of U.S. and U.K. scientists, aims to characterize the "colloidal shunt" mechanism whereby dissolved iron forms aggregates with organic matter, resulting in the vertical export of both particulate iron and organic...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $480,149 to the University of South Florida to conduct collaborative research on the ocean iron cycle in the subtropical and equatorial Pacific. Key objectives include:
Using iron isotopes as a tracer to quantify the relative supply of dust, sediment, and hydrothermal-derived iron to the South Pacific gyre and equatorial upwelling zone, and how iron supply varies spatially and...
This $700,000 Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) supports research at Princeton University to investigate how iron-starved bacteria respond and adapt to additional stresses, such as nitric oxide exposure. The key objectives are to: (i) understand how iron-starved bacteria obtain iron for stress responses, (ii) determine how iron-limited metabolisms generate sufficient reducing power for new stress responses, and (iii)...
This $691,259 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research effort between U.S. and U.K. scientists to investigate the linkages between the oceanic cycles of iron and organic carbon. The research aims to better characterize the "colloidal shunt" mechanism, whereby dissolved iron forms aggregates with organic matter to create particulate material that sinks out of the upper water column. The project will...
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...
This Project Grant from the National Science Foundation Division of Ocean Sciences provides $456,072 to the University of California San Diego's Scripps Institution of Oceanography for collaborative research titled "Functional Genomic Investigations of Iron and Carbon Cycle Coupling in Select Keystone Marine Bacteria Heterotrophs." The research aims to strengthen fundamental understanding of integrated Earth system processes through the Geosciences program (CFDA 47.050)....
