- 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,...
- This $377,603 Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will fund research by the University of Colorado to investigate the effects of transient and non-Newtonian mantle viscosity on glacial isostatic adjustment (GIA) processes and their implications for GPS observations in Antarctica. The project aims to build an accurate and efficient computer model to study the displacement and deformation of the Antarctic crust and mantle in response to...
- The National Science Foundation Division of Earth Sciences awarded a $656,841 project grant to the Berkeley Geochronology Center to improve the 40Ar/39Ar geochronometer. The goal of this three-year grant, which runs from August 2021 through July 2024, is to strengthen and enhance the national scientific enterprise through basic research in the earth sciences, as outlined in the Geosciences program (CFDA 47.050). Specifically, the Berkeley Geochronology Center will work to enhance the precision...
- The National Science Foundation Division of Earth Sciences awarded a $491,397 Project Grant to the Berkeley Geochronology Center to support the acquisition of a multicollector mass spectrometer for 40Ar/39Ar geochronology. With a completion date of July 31, 2023, this award will provide funding for the Center to obtain a new mass spectrometry instrument to strengthen its capabilities for determining the absolute ages of geological samples using isotopic dating techniques. This supports the goals...
- This three-year project grant from the National Science Foundation Division of Polar Programs, titled "Collaborative Research: Site Survey for Subglacial Bedrock Exposure Dating at the Margin of the Wilkes Basin in Northern Victoria Land," provides $116,342 to support basic research activities that are best conducted in Antarctica's polar regions. Funded under the NSF's Polar Programs (CFDA 47.078) to expand fundamental polar knowledge and understanding, the award will allow the...
- The National Science Foundation (NSF) awarded a $299,055 Project Grant under the Polar Programs (CFDA 47.078) federal grant program to the University of California Santa Cruz (UCSC) to investigate how variations in Earth's orbital patterns influence surface melting and the climate of Antarctica. The researchers will identify and date past periods of ice melting on the Antarctic continent using uranium-thorium dating of pedogenic carbonates deposited by meltwater, with the goal of correlating...
- This $269,928 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research to use beryllium-10 (10Be) anomalies from solar proton events as a method for verifying varve chronologies in Arctic lake sediments. The research team at the University of Massachusetts will analyze 10Be concentrations in laminated sediment cores collected from sub- to high-Arctic lakes to determine if 10Be increases associated with solar proton events can reliably...
- This Project Grant award, valued at $359,487, was provided by the National Science Foundation's Polar Programs (CFDA 47.078) to The Trustees of Princeton University. The funding will be used to develop advanced analytical methods for high-resolution chemical imaging and dating of ancient ice cores from Antarctica's Blue Ice Areas, which contain climate records spanning over 1 million years. Specifically, the project will utilize cryo-cell laser ablation inductively coupled plasma mass...
This $399,064 project grant from the National Science Foundation's Polar Programs will support targeted basic research to enable Antarctic science applications of cosmogenic-nuclide geochemistry. The Berkeley Geochronology Center will conduct experiments to improve techniques for determining the age of glacial deposits in polar regions, specifically Antarctica. This includes developing a "virtual mineral separation" approach to cosmogenic noble gas analysis and identifying non-cosmogenic background inventories to improve measurement sensitivity and precision for cosmogenic radionuclides. Additional work aims to enhance capabilities for measuring multiple cosmic-ray-produced nuclides in a single sample. Successful experiments are expected to advance applications of cosmogenic-nuclide geochemistry relevant to Antarctic research, such as dating subglacial bedrock exposure and glacial deposits over millions of years. This supports the NSF's mission to strengthen polar scientific enterprise through expanded fundamental knowledge and understanding under the CFDA title "Polar Programs."
