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 three-year Project Grant from the National Science Foundation's (NSF) Polar Programs ($489,233) supports research into the last deglaciation period in Greenland. Oregon State University is the primary awardee and will work with sub-awardee University of Washington to strengthen understanding of this "mystery interval" through basic scientific exploration best conducted in polar regions, as outlined in the NSF's CFDA #47.078 program. Specifically, the awardees will conduct...
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) awarded a $505,558 project grant under the Polar Programs (CFDA 47.078) to Oregon State University. The 3-year grant, which began on October 1, 2023, will support a collaborative research project to elucidate the ocean dynamics governing melt at glaciers using Lagrangian floats. The research aims to determine the physical processes causing melting at an Alaskan glacier that ends in a fjord, focusing on whether recirculating cells and waves below the...
This $683,266 Project Grant awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) aims to reconstruct global ice volume and bottom water temperature over the past 1-3 million years. The project at Brown University will analyze multiple climate proxies, including biomarkers and stable isotopes, using machine learning algorithms to resolve global ice volume and ocean temperature signals. The key objectives are to assess the role of CO2 and ice albedo in global...
This $254,639 Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will fund research to advance paleoclimate reconstruction techniques using thin or disturbed ice core sections. The University of Washington will develop new instrumentation and data workflows at the National Science Foundation Ice Core Facility to investigate sub-centimeter chemical and physical variations in polar ice cores. Researchers will...
This $397,492 federal Project Grant award was provided by the National Science Foundation (NSF) under its Geosciences Program (CFDA 47.050) to study the melting of ice sheets during the last interglacial period approximately 130,000 to 115,000 years ago. The project, led by The Trustees of Columbia University in the City of New York, aims to better understand when and how much the Greenland and Antarctic ice sheets melted, as well as the climate conditions and ice dynamics that drove their...
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 $269,580 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research at Oregon State University to improve paleoclimate reconstruction in high-latitude regions. The university will develop new and enhanced trace element to calcium paleoproxies for understudied temperate to polar planktic foraminiferal species found in the Northern California Current region. Researchers will establish magnesium to calcium-temperature and sodium to calcium-salinity...
Oregon State University received a $282,979 project grant award from the National Science Foundation Division of Polar Programs to study submesoscale fjord variability and its influence on glacial melt from January 1, 2022 to December 31, 2023. The award supports research that aligns with the goals of the Polar Programs federal grant program authorized under the Catalog of Federal Domestic Assistance number 47.078, which aims to strengthen fundamental understanding of polar regions through basic...
