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 $1.5 million National Science Foundation project grant supports research into secondary marine aerosol precursors and their links to aerosol growth during Arctic sea ice melt onset. Funded under the Geosciences program (CFDA 47.050), the goal is to advance understanding of secondary marine aerosol formation in the atmosphere and its impact on cloud properties and climate. Colorado State University will conduct measurements of volatile organic compounds and reduced sulfur compounds aboard...
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...
The National Science Foundation Division of Polar Programs awarded South Dakota State University a $380,435 project grant to conduct collaborative research on climate-induced sea-level rise, warming, and herbivory effects on vegetation and greenhouse gas emission in coastal western Alaska. This award, made under the Polar Programs (CFDA 47.078) federal grant program on February 1, 2022, will support research through January 31, 2026 that aims to strengthen understanding of fundamental...
This $194,921 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund collaborative research to constrain and understand regional modes of variability in the Atlantic Arctic over the next two years. The overarching goal is to quantitatively study climate patterns and their long-term changes in the Atlantic Arctic and sub-Arctic regions using a variety of data sources, including meteorological measurements, historical observations, and climate...
This $248,000 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund a collaborative research project to investigate past Arctic sea ice coverage and its biogeochemical impacts. The research team, led by 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, focusing on the Holocene Thermal Maximum and Last Interglacial periods. The...
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...
This Project Grant award of $417,518.00 from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research to investigate the impacts of high latitude dust deposition on the Arctic cryosphere, with a focus on the Svalbard region. The key objectives are to: 1) determine the spatial and temporal variability of dust deposition onto Svalbard glaciers, 2) discern the sources of the dust, 3) assess the contribution of dust and black carbon to snow and glacier melt processes, 4)...
This Project Grant award from the National Science Foundation's 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 $462,000 award, effective July 1, 2025 through June 30, 2028, will fund the analysis of ocean sediment cores to reconstruct historical Arctic sea ice extent and ocean conditions during two key warm periods - the Holocene Thermal Maximum (~8,000 years ago)...
This $250,771 Project Grant was awarded by the National Science Foundation (NSF) Division of Polar Programs to Colorado State University to conduct collaborative research on the interaction between Antarctic low clouds and natural aerosols. The research aims to improve global climate model simulations over Antarctica and the Southern Ocean by better representing low-level cloud physics, which have significant impacts on ice surface melt and solar energy transmission. The 4-year project will...
