This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $113,988 to the University of California, Santa Barbara (UCSB) aims to improve understanding of the biological carbon pump in ocean oxygen minimum zones. The researchers will conduct field observations in the Eastern Tropical North Pacific to measure characteristics of sinking particulate organic carbon, including particle abundance, size, sinking rates, and remineralization. These data will be...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $562,895.00 to the Regents of the University of Minnesota to conduct collaborative research on the role of the "colloidal shunt" in mediating interactions between the ocean's iron and carbon cycles. The research aims to better characterize the mechanisms and linkages between dissolved organic carbon, iron-binding organic ligands, and the formation of particulate iron in the ocean....
This Project Grant award for $540,281 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project between U.S. and U.K. scientists to better understand the linkages between the oceanic cycles of iron and carbon. The research aims to characterize the "colloidal shunt" mechanism, whereby dissolved iron forms aggregates with organic carbon to create particulate matter that sinks out of the upper water column. The project will...
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...
The University of Rochester received a $575,843 Project Grant award from the National Science Foundation Division of Ocean Sciences. The grant is part of the NSF's Geosciences program (CFDA 47.050) and will fund the PROBING THE OCEAN'S MULTISCALE PATHWAYS project from September 1, 2021 through August 31, 2024. Through this award, the University of Rochester will conduct basic research to strengthen understanding of the integrated Earth system and ocean sciences. Specifically, the funding will...
This Project Grant award for $197,103, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research effort to better understand the linkages between the oceanic cycles of iron and carbon. 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 advanced ocean biogeochemical modeling. Key areas of focus include examining...
This $665,899 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to investigate the impacts of plastic-derived dissolved organic carbon (PDOC) on ocean biogeochemistry and the biological carbon pump. The project will utilize a combination of laboratory experiments, field sampling, and numerical modeling to test the hypothesis that bacteria consuming PDOC compete with phytoplankton for key nutrients like nitrogen and...
This Project Grant of $533,586 was awarded by the National Science Foundation (NSF) Division of Ocean Sciences to the Woods Hole Oceanographic Institution (WHOI), a private non-profit research organization, on April 1, 2024. The grant is part of the NSF's Geosciences program (CFDA 47.050), which supports fundamental research to expand knowledge and understanding of the Earth system. The research funded under this award aims to quantify the transport and fate of carbon exported into the...
This National Science Foundation Project Grant under the Integrative Activities program (CFDA 47.083) provides $221,015 to the University of New Hampshire from February 2022 to January 2024 to investigate changes in Arctic Ocean phytoplankton and track the vertical export of organic carbon they produce. Working with optical oceanography experts at the Scripps Institution of Oceanography, the University will analyze data from 2010-2021 field campaigns measuring inherent and apparent optical...
This Project Grant award of $300,774, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to understand how efficient particulate organic carbon transfer occurs in the ocean's oxygen minimum zones. The University of Rochester will conduct observations and modeling to test three hypotheses about how low oxygen conditions in these regions impact the size distribution and remineralization of sinking carbon particles. Key datasets will include particulate organic carbon flux profiles, remineralization rates, particle size distributions, and zooplankton abundance across the oxic-anoxic transition. The research aims to improve understanding of changes to the biological carbon pump that could occur as ocean oxygen levels decline due to climate change. The award has an end date of August 31, 2027.
