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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research effort to investigate the impact of plastic-derived dissolved organic carbon (PDOC) on the ocean's biological carbon pump. The $569,435 award to Northeastern University, with a project period from April 1, 2025 to March 31, 2028, will leverage a combination of laboratory experiments, field sampling, and numerical modeling to test the hypothesis that bacteria...
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 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $665,899 to the University of New Hampshire (UNH) to research the impact 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 explore how bacteria consume PDOC and compete with phytoplankton for key nutrients like nitrogen...
The National Science Foundation Division of Ocean Sciences awarded a $378,315 Project Grant to the Woods Hole Oceanographic Institution for research activities under the Geosciences program (CFDA 47.050). The two-year award, beginning February 1, 2022 through January 31, 2024, will support research to detect signatures of multigenerational plasticity in a marine forage fish. The Geosciences program seeks to expand fundamental knowledge and understanding of the integrated Earth system through...
The National Science Foundation awarded a $429,900 three-year Project Grant to the University of New Hampshire under the Geosciences program (CFDA 47.050) to support the collaborative research project "Plastic Spiraling in River Networks." The goal of the project is to determine the controls on watershed plastic fluxes using fieldwork and modeling. Specifically, the grant will fund research from October 1, 2021 to September 30, 2024 to better understand how plastic debris moves through...
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...
The National Science Foundation (NSF) awarded a $150,354 CAREER grant (CFDA 47.050 - Geosciences) to Texas A&M University to conduct research on atmospheric micro- and nanoplastic particles. The 5-year project, which commenced on March 15, 2025, aims to provide a comprehensive understanding of the sources, spatial concentrations, chemical processes, and climate impacts of these particles in the atmosphere. The research will combine laboratory studies and mobile field measurements in the...
This $300,000 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to determine the impact of microplastics on the distribution of naturally-occurring radioactive isotopes in the marine environment. The University of Rochester will lead this 2-year project, which aims to quantify the association of select particle-reactive radioisotopes with plastics through a combination of laboratory experiments and field work at coastal and...
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...
