This $665,899 Project Grant was awarded on April 1, 2025 by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) to the University of New Hampshire (UNH). The grant will fund a collaborative research project to investigate the effects of plastic-derived dissolved organic carbon (PDOC) on the ocean's biological carbon pump. The project will utilize a combination of laboratory experiments, field sampling, and numerical modeling to test the hypothesis that bacteria consume...
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 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...
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...
This Project Grant award from the National Science Foundation's (NSF) Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will investigate the photochemical breakdown of marine dissolved organic matter (DOM) and its impact on the global carbon cycle.
The $683,778 award, valid from July 2023 to June 2026, will focus on studying the production rates and quantum yields of one and two-carbon photoproducts, such as carbon monoxide, dissolved inorganic carbon, formaldehyde, and...
This Project Grant award of $478,560, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), aims to unravel the formation and impact of the plastisphere - a unique microbial habitat that develops on microplastics in soil. The multidisciplinary research team from Cornell University and the University of Aberdeen in the UK will examine how various microplastics, including biodegradable ones, age in different soils and assess their impact on soil pore structure and water...
This $137,593 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to improve understanding of the biological carbon pump in the ocean's oxygen minimum zones. The project aims to measure particle abundance, size, and sinking rates, as well as the processes that break down organic matter, across the oxic-anoxic transition in the Eastern Tropical North Pacific. The researchers will incorporate these new observations into a mechanistic...
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....
This National Science Foundation (NSF) Project Grant, awarded under the Geosciences program (CFDA 47.050), is providing $300,000 in funding to the University of Rochester from September 1, 2024 through August 31, 2026. The goal of this project is to determine how the presence of microplastics in the ocean may impact the distribution of naturally-occurring radioactive isotopes, which are commonly used to track processes associated with natural particles like sediments and biological materials....
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...
