- 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 $513,000 Project Grant award was provided by the National Science Foundation (NSF) Division of Polar Programs from August 1, 2023 to July 31, 2026. The grant supports collaborative research by the University of Colorado to assess the causal influence of atmospheric opacity (clouds) and sea ice thickness on Arctic warming over the past 40 years and into the near future. Key deliverables include quantifying the impact of these factors on Arctic warming rates using a novel modeling approach,...
- The Trustees of Columbia University in the City of New York was awarded a $269,851 project grant from the National Science Foundation (NSF) Division of Polar Programs to quantify the spatial distribution of micro- and nanoplastics along an Antarctic traverse from the coast to the South Pole. This EAGER (Early-concept Grants for Exploratory Research) project will leverage snow samples collected during an unsupported ski traverse to analyze the concentration of these pollutants using a...
- This $248,000 Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will support a collaborative research project to investigate Arctic sea ice coverage and its biogeochemical impacts over the past 150,000 years. The research team at the University of Massachusetts Boston will analyze ocean sediment cores to reconstruct historical Arctic sea ice extent and ocean conditions during past warm periods, including the Holocene Thermal Maximum and the Last...
- The National Science Foundation Division of Polar Programs awarded Colorado State University a $673,107 Project Grant under the Polar Programs (CFDA 47.078) federal grant program. The grant will support improved understanding of aerosol-cloud interactions during the Arctic sea ice melt period from May to June 2023. As part of the Swedish-led ARTOFMELT expedition aboard the icebreaker Oden in the Arctic Ocean, the university will conduct observations and modeling to characterize aerosol...
- This three-year, $459,000 Project Grant from the National Science Foundation's Mathematical and Physical Sciences program (CFDA 47.049) will fund research into the origins and mitigation of secondary microplastics and nanoplastics pollution. The grantee, Columbia University, will combine experimental and theoretical tools to elucidate the degradation mechanisms of semicrystalline polymers when exposed to mechanical forces, water, air and UV light. This work aims to delineate the critical physics...
- The National Science Foundation's (NSF) Polar Programs (CFDA 47.078) awarded a $288,448 Project Grant to Oregon State University to conduct collaborative research on using X-ray tomography to characterize the microstructure of sea ice during stress tests. The goal is to develop multiscale numerical models that link the micromechanics of sea ice to its macroscopic behavior, which is critical for improving Arctic navigation, infrastructure design, and climate adaptation strategies. This research...
- This $412,318 Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) will fund research to improve understanding of plastic flows and develop solutions to mitigate plastic waste contamination. The Colorado School of Mines will conduct this 3-year project to create a material flow analysis (MFA) model that tracks macro, micro, and nano plastics across different geographic environments in the U.S. and Caribbean. This research aims to correlate...
This $590,883 Project Grant from the National Science Foundation Division of Polar Programs will fund research into sea ice-ocean exchange of microplastics in the Arctic. The grant was awarded on March 1, 2022 to the Regents of the University of Colorado under the NSF's Polar Programs CFDA number 47.078. Through a combination of laboratory studies and numerical modeling, researchers will develop new techniques to understand the uptake and release of microplastics between sea ice and ocean water, including the impact of marine gels. They will also measure microplastics' optical effects on sea ice mass balance. Based on lab insights, the team will develop and test parameterizations for including microplastics in open-source sea ice, ocean and climate models at both vertical column and fully coupled scales. Hindcast and future simulations will assess microplastics' large-scale Arctic distribution and climate impacts. The research aims to advance understanding of this pollution issue in the polar regions under the NSF's mission of expanding polar knowledge.
