The National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences awarded a $227,159 Project Grant to the University of Utah to conduct a year-long measurement campaign to quantify mercury speciation and oxidation rates in the atmosphere near a magnesium mining facility in Salt Lake City, Utah. The primary objectives are to: 1) Measure elemental and divalent mercury, related oxidants, and other chemical and meteorological variables; 2) Use a zero-dimensional chemical...
The University of Connecticut is conducting a $680,675 project grant awarded by the National Science Foundation's Division of Ocean Sciences under the Geosciences Program (CFDA 47.050) to study the air-sea exchange of inorganic and methylated mercury in the Sargasso Sea. The study aims to evaluate the concentrations of mercury in the surface ocean and atmosphere, examine the factors controlling its chemistry, and quantify the sources and sinks of mercury. Researchers will collect high-resolution...
This two-year Project Grant from the National Science Foundation (NSF) totaling $149,737 will support research into heterogeneous reactions of mercury in the Arctic environment under the NSF's Mathematical and Physical Sciences program (CFDA 47.049). Professor Asaduzzaman of Pennsylvania State University will lead a team studying the interactions of oxidized mercury species with snow and ice through quantum chemical calculations. The research aims to characterize elementary steps controlling how...
The National Science Foundation awarded a $496,117 project grant to Mississippi State University from September 1, 2021 through August 31, 2024 under the Mathematical and Physical Sciences program (CFDA 47.049). The grant supports collaborative research on the kinetics and quantitative spectroscopy of atmospheric mercury redox chemistry.

The National Science Foundation Division of Atmospheric and Geospace Sciences has awarded a $178,063 Project Grant titled "COLLABORATIVE RESEARCH: VERIFICATION OF ATMOSPHERIC MERCURY REDOX RATES" to Brigham Young University. This 3-year grant, effective September 1, 2023, will fund a collaborative research project to quantitatively characterize the speciation of mercury and radical budget in the Salt Lake City region. The key objectives are to: (1) conduct year-long measurements of...
This $616,131 National Science Foundation project grant will fund the development of observation-based metrics to evaluate global atmospheric chemistry models at the University of California, Irvine through January 2025. As part of its Geosciences program, which supports basic research in atmospheric, earth, and ocean sciences, the NSF aims to strengthen the scientific enterprise's understanding of the integrated Earth system. Under this award, the university will design, test, and document a...
The University of Utah will receive $345,496 under a two-year Project Grant from the National Science Foundation Division of Earth Sciences through the Geosciences program (CFDA 47.050) to develop new methods for measuring mercury and methylmercury isotopes in high-salinity, high-dissolved organic matter environments. Current methods cannot be used in these conditions, inhibiting understanding of mercury pathways into wildlife. The University will work with the U.S. Geological Survey to devise...
This $667,306 project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences Geosciences program (CFDA 47.050) will fund research into the atmospheric chemistry of methylated selenium compounds and the physicochemical properties of resulting aerosols. The awardee, Regents of the University of California at Riverside, will utilize an environmental chamber to quantify secondary organic aerosol formation from selenium-containing organic compounds. Gas and aerosol...
