This $453,714 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) aims to synthesize data on the role of coastal sediments in the carbon cycle along the East Coast of the United States. The three-year project, awarded to Trustees of Boston University, will gather long-term sediment and water column datasets, integrate them with models, and characterize patterns of benthic carbon, oxygen, and nutrient fluxes in the Northeast U.S. region. The research...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $569,435 to Northeastern University to conduct research on the impacts of plastic-derived dissolved organic carbon (PDOC) on ocean biogeochemistry and the biological carbon pump. The core hypothesis is that bacteria consuming PDOC will compete with phytoplankton for key nutrients like nitrogen and phosphorus, reducing new production and the strength of the biological carbon pump. The...
The National Science Foundation (NSF) awarded a $552,775 Project Grant under the Geosciences program (CFDA 47.050) to Florida State University (FSU) for a research project titled "Collaborative Research: Constraining Benthic Iron Fluxes in the Labrador Sea." The project aims to study the role of ocean sediments in supplying iron, a key nutrient, to the surface waters of the Labrador Sea between Canada and Greenland. The research team will collect sediment and pore water samples to...
This $349,370 National Science Foundation project grant supports research at Coastal Carolina University from July 2022 to June 2025 under the Geosciences program (CFDA 47.050). The university will investigate the influence of ocean sediments on neodymium isotope signatures as tracers of deep water circulation patterns in the North Atlantic. Researchers hypothesize that sediments are a primary source of rare earth elements to ocean waters, in contrast to existing models considering sediments...
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...
The National Science Foundation awarded a $243,076 Project Grant to Northeastern University under the Geosciences program (CFDA 47.050) for the period of September 1, 2021 through August 31, 2023. The grant will support the collaborative research project "Assessing the Contribution of Plastics to Marine Particulate Organic Carbon." The Geosciences program seeks to expand fundamental knowledge and understanding of the integrated Earth system through basic research in atmospheric,...
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....
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 $387,090 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project to enhance understanding of nitrogen cycling in deep-sea hydrothermal vent ecosystems. The project will employ specialized equipment to conduct nitrogen cycling experiments under high-pressure conditions at seafloor vent habitats, addressing limitations of prior studies conducted at atmospheric pressure. The work will measure rates of...
This National Science Foundation (NSF) Project Grant award under the Geosciences Program (CFDA 47.050) provides $134,212 to the Woods Hole Oceanographic Institution (WHOI) to investigate benthic iron fluxes in the Labrador Sea. The project aims to understand how sediments on the continental shelf supply iron, an important nutrient, to the surface waters of the Labrador Sea, which can influence biological productivity and the global carbon cycle. Researchers will collect sediment and pore...
This National Science Foundation (NSF) Geosciences program (CFDA 47.050) Project Grant award provides $354,605 to Northeastern University to synthesize and analyze data on the role of shallow benthic fluxes in the coastal carbon cycle along the East Coast of the United States. The 3-year project, which begins on April 1, 2025, aims to:
Combine observational data, modeling results, and re-analyses to evaluate how environmental conditions impact benthic fluxes of carbon, oxygen, and nutrients in the Northeast U.S. coastal region.
Characterize spatial and temporal patterns in benthic fluxes and their relationship to pelagic biogeochemical cycles.
Develop community-driven guidelines for data use and future sediment research observations.
This effort addresses critical knowledge gaps around the importance of coastal seafloor sediments in carbon and nutrient cycling. The project will support an early career scientist, one Ph.D. student, and one postdoctoral researcher, with results disseminated through publications, scientific conferences, stakeholder workshops, and public outreach.
