This $254,882 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research investigating the sensitivity of reactive halogen abundance to glacial-interglacial climate change. Over a three-year period ending June 2025, the University of Rochester will examine how blowing snow on sea ice may explain increased sodium ion observations in ice cores over glacial-interglacial timescales. The project will also identify major drivers for reactive halogen...
The National Science Foundation's Geosciences program awarded a $148,749 project grant to the University of Alaska Fairbanks (UAF) to reanalyze previously collected reactive halogen spectroscopy data from Arctic observing buoys. The purpose is to study the potential synergies between bromine and iodine chemistry and their impact on Arctic ozone depletion, with a focus on the role of iodine. The research team will quantify seasonal and regional distributions of iodine and bromine, validate the...
This three-year, $627,411 project grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will support research on recent changes in Arctic biogenic sulfur aerosols through analysis of a central Greenland ice core. The University of Washington, as prime awardee, will collaborate with the University of St. Andrews to measure the concentrations and sulfur isotope compositions of methane sulfonic acid and sulfate in...

The Geosciences program aims to expand fundamental knowledge of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. This Project...
This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will provide $462,000 to the University of Washington to investigate Arctic sea ice coverage and ocean conditions over the past 150,000 years. The research team will use advanced geochemical techniques, including helium and thorium isotopes and nitrogen isotope analyses, to reconstruct historical sea ice extent and ocean nutrient levels. This data will be collected from sediment cores spanning a range of...
This National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences Project Grant award, under the Geosciences program (CFDA 47.050), provides $158,059 to Colorado State University from July 1, 2023 to June 30, 2026. The funding will support collaborative research to understand the impact of declining Arctic sea ice on summertime climate change, including the effects on atmospheric circulation patterns, heat waves, and extreme weather. The research approach includes analysis...
This $109,690 Project Grant award from the National Science Foundation's Polar Research (CFDA 47.078) program will support a collaborative research project to obtain new ice cores from Antarctica and analyze them to improve understanding of galactic cosmic ray flux and the Holocene methane budget. The project will use measurements of in-situ cosmogenic carbon-14 in the ice cores to test the assumption of a constant galactic cosmic ray flux over time, which is crucial for studies of past solar...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $312,259 to the University of Alaska Fairbanks (UAF) to conduct collaborative research on the last interglacial period approximately 130,000 to 115,000 years ago, when temperatures were naturally warmer than today. The project aims to better understand when and how much the Greenland and Antarctic ice sheets melted during this period, as well as the climate conditions and ice dynamical...
The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $596,537 Project Grant to the University of Chicago to conduct collaborative research on understanding the impact of Arctic sea ice loss on summertime climate change. This 3-year award, which runs from July 1, 2023 to June 30, 2026, is funded under the NSF Geosciences program (CFDA 47.050) to support basic research that expands knowledge and understanding of the Earth system. The key objectives of the...

This Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), provides $486,913 to the University of Washington for collaborative research investigating glacial-interglacial variability in tropospheric reactive halogens. Specifically, the research will examine how blowing snow on sea ice can explain increases in sodium ions observed in Greenland and Antarctic ice cores over glacial-interglacial timescales. It will also identify the main drivers of changes in reactive halogen abundance and potential implications for atmospheric oxidizing capacity and short-lived climate forcers such as methane, tropospheric ozone, and aerosols. By improving understanding of reactive halogens over major climate transitions and their role in climate feedbacks, this research aims to advance knowledge of the Earth system. The award period is from July 15, 2022 to June 30, 2025 and also provides support for graduate and undergraduate students.
