The National Science Foundation awarded a two-year, $174,000 Project Grant to Princeton University under the Geosciences program (CFDA 47.050). The grant will fund research examining the effect of environmental conditions on the degradation pathways and sorption potential of microplastics and nanoplastics as vectors for inorganic pollution. The Geosciences program supports basic research to strengthen understanding of Earth's integrated system through atmospheric, earth, and ocean sciences. This...
This $665,899 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to investigate the impacts of plastic-derived dissolved organic carbon (PDOC) on ocean biogeochemistry and the biological carbon pump. The project will utilize a combination of laboratory experiments, field sampling, and numerical modeling to test the hypothesis that bacteria consuming PDOC compete with phytoplankton for key nutrients like nitrogen and...
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, earth,...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $346,823 Project Grant to the Regents of the University of Colorado (doing business as the University of Colorado) to conduct research under the NSF Geosciences program (CFDA 47.050). This research project aims to better understand how transformations to microplastics in coastal environments impact their regional-scale transport and fate. The study will use Lagrangian tracers and existing hydrodynamic modeling to quantify...
This Project Grant award of $299,999 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports fundamental research to understand the trapping of microplastic particles in riverbeds. The project leverages synergistic pore-resolving direct numerical simulations and theoretical modeling to reveal the physical processes involved in microplastic trapping and develop predictive models for retention rates across various flow, bed, and particle configurations. The research...
The National Science Foundation Division of Earth Sciences awarded a $418,107 Project Grant to Loyola University of Chicago to support the collaborative proposal "Plastic Spiraling in River Networks (PLASTIC-SIREN): Determining the Controls of Watershed Plastic Fluxes Using a Field and Modeling Approach." The three-year award period runs from October 1, 2021 to September 30, 2024. Under this award, Loyola University will work with partners to study plastic pollution transport through...
This National Science Foundation (NSF) Project Grant under the Geosciences program (CFDA 47.050) provides $358,976 to Hobart & William Smith Colleges to conduct collaborative research on microplastic sources, transport, and environmental impact across the Finger Lakes watershed in New York. The 3-year project offers mentored research opportunities for college sophomores, who will learn to design research projects, collect field data, and analyze microplastic samples using advanced equipment....
This $399,836 federal Project Grant awarded by the National Science Foundation (NSF) under the Social, Behavioral, and Economic Sciences (CFDA 47.075) program supports research to examine the sources and spatial distribution of microplastics in rivers. The project at Texas A&M University will characterize the extent of microplastic pollution in different watersheds and analyze how human activities and land use patterns impact the geographical distribution of these particles. The research...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award provides $344,888 to Arizona State University (ASU) from August 15, 2024 to July 31, 2027 to conduct collaborative research on understanding the trapping of microplastic particles in riverbeds. The research leverages synergistic pore-resolving direct numerical simulations and theoretical modeling to reveal the physical processes involved in microplastic trapping within riverbed pores. This will enable...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $231,803 to the Research Foundation of the City University of New York (RFCUNY) provides mentored undergraduate research opportunities focused on studying microplastics in the Finger Lakes watershed of New York. The 3-year project will engage college sophomores in field research to identify sources, sinks, transport, and environmental impacts of microplastics in the local water systems. Students...
