Project Grant 2139293
- The National Science Foundation Division of Polar Programs awarded a $327,921 Project Grant to the Nevada System of Higher Education to support research being conducted at the Desert Research Institute from October 1, 2021 to September 30, 2023. Under the grant, the Desert Research Institute will investigate over 2,500 years of human history and atmospheric transport in Greenland ice using high-resolution lead isotopic records. The research is intended to strengthen fundamental scientific...
- 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...
- This $248,000 federal Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) supports a collaborative research project to investigate historical Arctic sea ice coverage and its biogeochemical impacts. The research team at the University of Massachusetts Boston will analyze ocean sediment cores to reconstruct Arctic sea ice extent and ocean conditions over the past 150,000 years, with a focus on the Holocene Thermal Maximum and the Last Interglacial periods....
- This $594,726 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) supports research to investigate historical sources of lead pollution in the northern hemisphere over the past 2,500 years. The research team, led by the Desert Research Institute (DRI), will use inverse modeling of lead isotopes in high-resolution Arctic ice cores to quantify emissions from specific historical sources such as mining, smelting, coal combustion, and oil/gasoline...
- This Project Grant award from the National Science Foundation (NSF) Division of Polar Programs (CFDA 47.078) provides $814,685 to the University of California Irvine (UC Irvine) to analyze molecular hydrogen (H2) in an ice core from Summit, Greenland. The goal is to reconstruct atmospheric changes in H2 over the past millennium, which will establish a baseline to assess how human activities have influenced atmospheric H2 since the preindustrial era. The research involves drilling a new ice core,...
- This three-year, $424,310 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. South Dakota State University, as awardee, will collaborate with the University of St. Andrews in the United Kingdom to measure sulfate isotopes in shallow ice cores and archived ice samples dating back to...
- 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 Project Grant award from the National Science Foundation's Polar Research (CFDA 47.078) program provides $755,980 to the University of Rochester to obtain and analyze new ice cores from Antarctica's Dome C. The research aims to improve understanding of the history of galactic cosmic ray flux and the global methane budget over the Holocene period. Key activities include: Measuring in-situ cosmogenic carbon-14 in the ice cores to test the assumption of a constant galactic cosmic ray flux,...
- The National Science Foundation (NSF) Division of Polar Programs awarded a $532,387 Project Grant to Oregon State University to investigate past atmospheric methane variability using stable isotopes in Antarctic ice cores. The research project aims to develop new laboratory methods for measuring hydrogen isotopes in methane and use the chemical composition of methane to understand changes in atmospheric methane levels during past climate transitions, including periods when the climate was as...
- This Project Grant award of $325,875.00 from the National Science Foundation's Division of Polar Programs (CFDA 47.078) supports research at the University of Alaska Fairbanks (UAF) to assess the contribution of permafrost-derived greenhouse gases to global warming since the last glacial maximum. The project combines data on permafrost thaw records, paleoclimate evidence, and ice core-based greenhouse gas concentrations to better understand the effects of warming and permafrost instability on...
This two-year, $378,322 National Science Foundation project grant supports research investigating potential in situ biological production of carbon monoxide and methane in Arctic ice cores at Desert Research Institute. The grant aims to develop high-resolution Arctic records of these two greenhouse gases free from any artifacts by evaluating post-collection ice temperature effects on gas production. A 150-meter ice core will be collected from Summit, Greenland and subjected to successive gas measurements under controlled temperature conditions to investigate rate and timing of biological gas production. Additional portions of the core will undergo microbial and chemical analyses using existing analytical systems to determine roles of impurities and microbial communities in situ gas production. This research aligns with the NSF's Polar Programs mission to advance fundamental polar science knowledge under the CFDA 47.078 program.
