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 National Science Foundation awarded a $244,878 project grant to the University of Delaware to support collaborative research titled "New Roles for Reactive Oxygen Species in Mediating Carbon Fluxes at the Terrestrial-Aquatic Interface." The three-year award runs from July 1, 2021 to June 30, 2024 under the NSF's Geosciences program (CFDA 47.050). This program aims to strengthen the national scientific enterprise through expanded fundamental knowledge and understanding of Earth's...
This $691,259 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project to better understand the relationship between the oceanic cycles of iron and carbon. The award, titled "COLLABORATIVE RESEARCH: NSFGEO-NERC: THE COLLOIDAL SHUNT AS A CRITICAL NEXUS OF THE OCEAN IRON AND CARBON CYCLES," will be performed by researchers at Oregon State University. The project aims to characterize the "colloidal...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $137,593 to the University of Maryland Center for Environmental Science (UMCES) will fund a collaborative research project to study the transfer of particulate organic carbon to the deep ocean in oxygen minimum zones. The project aims to improve understanding of the biological carbon pump by measuring particle abundance, size, sinking rates, and remineralization in the Eastern Tropical North Pacific...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $802,309 project grant to The Research Foundation For The State University Of New York, doing business as Stony Brook University, under the Geosciences program (CFDA 47.050). This grant will fund a 3-year research project to advance the understanding and quantitative modeling of how complex patterns of oxidation-reduction and acid-base reactions within the bioturbated zone of ocean sediments impact biogeochemical...
This National Science Foundation (NSF) Project Grant, awarded under the Geosciences program (CFDA 47.050), provides $499,806 to Bigelow Laboratory for Ocean Sciences to conduct collaborative research on the role of the "colloidal shunt" in the ocean's iron and carbon cycles. The project aims to better understand the mechanisms and linkages between iron and organic carbon pools in the oceans, and to predict their sensitivity to future environmental and climatic changes. The work will...
This Project Grant award, provided by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050), will fund a 5-year research project at the University of Delaware to investigate the cycling of organic carbon in aging oceanic crust. The $145,392 award, which began on March 1, 2025, aims to: (1) expand observations of fluid discharge sites on seamounts to better understand organic carbon dynamics in cool, aging oceanic crust; (2) develop new analytical tools for characterizing...
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...
The University of California, Santa Barbara will research what controls the marine refractory dissolved organic carbon reservoir through a $389,988 project grant from the National Science Foundation Division of Ocean Sciences' Geosciences program (CFDA 47.050). This three-year award beginning July 15, 2021 will fund collaborative research to strengthen understanding of the integrated earth system through basic research of the ocean sciences. Specifically, the university will investigate the...
The National Science Foundation Division of Ocean Sciences awarded a $300,000 Project Grant to the Massachusetts Institute of Technology for research titled "EAGER: Characteristic Disruptions of the Marine Carbon Cycle." The two-year award beginning in August 2021 will fund basic research under the Geosciences program (CFDA 47.050) to strengthen understanding of the integrated Earth system through support of investigations into the atmospheric, earth, and ocean sciences....
