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 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 $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 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will synthesize data on the role of coastal sediments in carbon and nutrient cycling along the East Coast of the United States. The $453,714 award to Trustees of Boston University, spanning April 2025 to March 2028, will combine sediment, water column, and modeling data to evaluate how environmental conditions influence benthic fluxes of carbon, oxygen, and nutrients in this relatively data-rich...
The National Science Foundation's Division of Ocean Sciences awarded a $264,724 Project Grant to the Virginia Institute of Marine Science (VIMS) to study the fate and transformation of terrestrially-derived organic carbon in the Northern Andaman Sea and Eastern Bay of Bengal. Specifically, the study will examine the residence time of sediment and the physical processes affecting the sequestration of organic carbon as it transits from the Ayeyarwady and Thanlwin river systems to the continental...
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...
This National Science Foundation Project Grant of $392,802 will fund research from March 2022 through February 2025 to quantify relationships between topography, soil properties, and soil organic carbon in fire-prone landscapes in Oregon. The awardee, University of Oregon, will collect data on the extent, depth, and age of soil organic carbon at recently burned mountainous study sites in southwest Oregon. The research aims to inform soil management and carbon sequestration efforts by examining...
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 Project Grant award of $599,974 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project by the University of Washington to reconstruct the history of ocean ventilation and circulation in the Northeast Pacific over the past 23,000 years. The key objectives are to improve understanding of the marine carbon cycle and enhance the utility of radiocarbon dating for marine sedimentary records. The project will leverage sediment cores and apply genomic...
This National Science Foundation Project Grant award of $360,269 will fund research into the chromatographic separation and degradation of dissolved and particulate organic matter in permeable shelf sediments. The award was made on June 1, 2022 to Florida State University's Sponsored Research Administration under the Geosciences program (CFDA 47.050) and is scheduled to be completed by May 31, 2025. The research will study how sandy sediments influence the carbon cycle through their ability to...
