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...
This $374,308 project grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research at Montana State University focused on understanding the pre-eruptive processes and timescales that trigger volcanic eruptions, particularly at Alaska's Okmok volcano. The research team will integrate geochemical analysis of erupted products with geophysical monitoring data to elucidate the deep magmatic processes that lead to different eruption styles, volumes, and...
The National Science Foundation Division of Atmospheric and Geospace Sciences awarded a $235,435 Project Grant to the University of Nevada, Reno (UNR) under the Geosciences program (CFDA 47.050) to conduct a collaborative research project on the verification of atmospheric mercury redox rates. The key objectives are to: (1) conduct year-long measurements of elemental and divalent mercury, related oxidants, and other variables; (2) use a zero-dimensional model to identify mercury chemical...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) grant, totaling $180,000, will support a 2-year postdoctoral fellowship project to study the influence of land cover on the isotopic signature of mercury in surface and subsurface soils across the conterminous United States. The project aims to quantify the relative importance of different mercury input pathways to soils by land cover type and the differences in isotopic signatures between surface and subsurface soils....
The National Science Foundation Division of Polar Programs awarded a $138,000 Project Grant to the Woodwell Climate Research Center Inc. under the Polar Programs federal grant program (CFDA 47.078). The award will fund research from September 2022 through August 2025 to study the mobilization, microbial transformation, and uptake of carbon and mercury from thawing permafrost soils into aquatic food webs in Arctic Alaska. Specifically, the grantee will conduct field studies using metagenomics and...
This three-year, $578,882 project grant from the National Science Foundation's (NSF) Polar Programs will support research to develop process-based terrestrial mercury models. Funded through the NSF's CFDA 47.078 program, the awardee will build models by leveraging existing terrestrial carbon cycle models. This will advance understanding of mercury processes in permafrost regions at multiple temporal and spatial scales. The models will predict pan-Arctic and global impacts of mercury released...
This Project Grant award of $1,388,877.00, funded by the National Science Foundation's (NSF) Social, Behavioral, and Economic Sciences (CFDA 47.075) program, supports research investigating the biogeochemical cycling and environmental risks of mercury contamination from artisanal and small-scale gold mining (ASGM) activities in Ghana. The research team, led by the University of Michigan, will employ mixed methods including community mapping, interviews, and environmental sampling and modeling to...
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...
This $151,738 National Science Foundation (NSF) Project Grant, awarded under the NSF Integrative Activities program (CFDA 47.083), will enable the University of Alaska Fairbanks (UAF) to conduct research on the magmatic source and eruption history of Mount Churchill in Alaska. The research aims to better understand the potential hazards posed by future explosive eruptions from this volcano, which has produced some of the largest ash fall events in North America over the past 2,000 years. Key...
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...
