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, totaling $226,865.00, was provided by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of Delaware. The purpose of the award is to collect high-resolution carbon isotope data on GO-SHIP cruises in the Indian and Pacific Oceans in order to better constrain ocean carbon uptake and storage. Specifically, the project will measure the ratio of carbon-13 to carbon-12 in dissolved inorganic carbon in seawater using a new, less expensive...
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 Project Grant award from the National Science Foundation Office of Integrative Activities provides $2,070,522 to the University of Delaware under the Geosciences program (CFDA 47.050) to investigate whether mid-ocean ridge hydrothermal vents control the formation and distribution of refractory aromatic carbon in the deep ocean. Over a three-year period from September 1, 2022 to August 31, 2025, the University will collect samples from hydrothermal vent fields along the East Pacific Rise 9°N...
This Project Grant award of $480,691.00 from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) supports research to quantify spatial and temporal changes in organic carbon sequestration within shelf sediments along the Umpqua River in Oregon. The project will revisit sites previously sampled in 2009 to map sedimentation and organic carbon deposition patterns using geophysical surveys and sediment core analyses. Researchers will examine how factors like river sediment...
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 $300,000 EAGER (Early-concept Grants for Exploratory Research) project, awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050), aims to examine whether chemical reactions can alter the composition of land-derived organic carbon in a way that makes it appear similar to marine organic carbon. The research team from Old Dominion University Research Foundation will conduct experiments to monitor the reaction rates and compositional changes of land-derived organic...
This $387,090 Project Grant, awarded by the National Science Foundation's Geosciences Program (CFDA 47.050), will support a collaborative research effort to enhance understanding of nitrogen cycling in deep-sea hydrothermal vent ecosystems. The project will employ specialized high-pressure equipment to conduct experiments measuring rates of nitrogen loss, recycling, and microbial assimilation across redox gradients at two distinct seafloor vent habitats. This work aims to address limitations...
This $308,515 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to study changes in pelagic ecosystem function and their impact on the carbon cycle from the Eocene to Oligocene periods (56-33.9 million years ago). The project aims to reconstruct changes in the South Atlantic subtropical gyre ecosystem and determine how these changes affected carbonate production and preservation during a time of...
The National Science Foundation awarded a $448,935 Project Grant to the Woods Hole Oceanographic Institution for research investigating the source and flux of dissolved organic carbon released from methane seeps to the deep ocean. The three-year award, made under the Geosciences program (CFDA 47.050), will support collaborative research from April 1, 2021 to March 31, 2024. The Geosciences program seeks to strengthen understanding of the integrated Earth system through basic research in...

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 dissolved organic matter; and (3) refine estimates of global organic carbon loss from the deep ocean via crustal processes. The project will also engage K-12 students and undergraduate students from primarily undergraduate institutions in the research through educational and outreach activities. No sub-awards are planned under this grant.
