Project Grant 2535139
- The National Science Foundation Division of Polar Programs awarded the University of Washington $759,968 on September 1, 2026, under the Polar Programs assistance listing (CFDA 47.078) to investigate the formation, evolution, and deformation of the basal ice unit in the Antarctic Ice Sheet using ice-penetrating radar data. The project will map basal ice unit characteristics—the distinct layer immediately above the Antarctic bed that lacks visible internal reflections—by examining thickness...
- The National Science Foundation Division of Polar Programs awarded the University of Washington $666,998 on September 1, 2026, under the Polar Programs assistance listing (CFDA 47.078) to investigate the causes, predictability, and implications of the recent decline in Antarctic sea ice and Southern Ocean warming. The project applies modeling approaches to understand why Antarctic sea ice cover reversed from a steady increase during 1979–2015 to rapid decline since 2015, and why the Southern...
- 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 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...
- The National Science Foundation Division of Polar Programs awarded the University of Washington $480,261 on October 1, 2026, under the Polar Programs assistance listing (CFDA 47.078) to assess the role of absorbed solar radiation, clouds, and boreal fire aerosols in the slowdown of Arctic warming and sea ice loss since 2005. The project will explore how changes in winds, cloud properties, and aerosol concentrations account for recent Arctic temperature and sea ice trends. Arctic...
- The National Science Foundation Division of Polar Programs awarded Oregon State University $446,705 on November 1, 2026, to develop the Bipolar Ice Core Chronology (BICC), a unified timescale synchronizing 14 Antarctic and 8 Greenland ice cores under the Polar Programs assistance listing (CFDA 47.078). The award funds construction of a synchronized chronological framework merging and updating four existing ice core dating frameworks that currently disagree by up to several thousand years. The...
- This National Science Foundation (NSF) Division of Polar Programs Project Grant award provides $300,642 to Oregon State University to trace polar sediments using short-lived radioisotopes in 75 years of Arctic and Antarctic sediment cores. The goal is to systematically study Arctic and Antarctic sediment accretion rates in order to improve the tools used to track changes in sedimentation, thereby helping coastal managers and decision-makers understand how climate change is impacting polar...
- Federal Project Grant Award Summary The University of Washington received a $462,000 Project Grant from the National Science Foundation (NSF) Division of Polar Programs (CFDA 47.078) effective July 1, 2025, through June 30, 2028. This collaborative research project delivers scientific research products focused on reconstructing historical Arctic sea-ice coverage and associated biogeochemical conditions over the past 150,000 years. The research team will analyze ocean sediment cores using...
- The National Science Foundation Division of Ocean Sciences awarded the University of Washington $389,919 on September 1, 2026, to develop and apply uranium-series dating of pteropod shells to generate absolute ages of marine sediments beyond the 50,000-year limit of radiocarbon dating. The research team will measure uranium and thorium decay in pteropod shells—calcium carbonate structures from tiny sea snails that accumulate at the seafloor—to establish a chronological framework for ocean...
- The University of Washington was awarded a $983,607 Project Grant from the National Science Foundation Division of Polar Programs to conduct research titled "COLLABORATIVE RESEARCH: GRATE ? INTEGRATING DATA AND MODELING TO QUANTIFY RATES OF GREENLAND ICE SHEET CHANGE, HOLOCENE TO FUTURE." The period of performance for this research is from September 1, 2021 through August 31, 2025. The grant was awarded under the NSF's Polar Programs (CFDA 47.078) to strengthen understanding of polar...
The National Science Foundation Division of Polar Programs awarded the University of Washington $377,363 on September 1, 2026, under the Polar Programs assistance listing (CFDA 47.078) to develop a new dating method for million-year-old Antarctic ice using cosmic-ray-produced isotopes. The project will measure aluminum-26 and beryllium-10 isotopes accumulated in ice cores retrieved by the NSF Center for Oldest Ice Exploration (COLDEX), which has obtained samples exceeding 6.5 million years in age from regions of complex ice flow near the Antarctic ice sheet's edge. The recipient will apply accelerator mass spectrometry to detect aluminum-26 at concentrations below 200 atoms per gram of ice and establish a dating method based on the aluminum-26/beryllium-10 ratio, which decays with a half-life of 1.43 million years. Work includes validation through measurement of multiple zero-age ice samples to assess the constancy and uniformity of atmospheric production ratios and investigation of deep in-situ production effects. The project will train students in ultra-sensitive analytical methods applicable to high-tech manufacturing, national security, and nuclear and aerospace engineering. Performance occurs in Seattle, Washington. The period of performance runs from September 1, 2026, through August 31, 2028. The University of Washington Office of Sponsored Programs administers the award as the prime recipient.
