Project Grant 1643248

This $397,492 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to better understand how the Greenland and Antarctic ice sheets responded to past climate changes during the Last Interglacial period approximately 130,000-115,000 years ago. The research aims to reconstruct the timing and magnitude of past ice sheet melting events using a combination of fieldwork, laboratory analyses, and climate/ice sheet modeling. The...

The National Science Foundation (NSF) Division of Polar Programs awarded a $356,436 Project Grant to the University of California San Diego (UCSD) Scripps Institution of Oceanography to study the temperature history of Antarctica during the last ice age. The project aims to calibrate the water isotope thermometer in East Antarctica using an improved gas thermometer based on nitrogen and argon isotopes from air bubbles in ice cores. This will help predict the magnitude of future warming in...

This three-year, $361,678 National Science Foundation project grant supports research investigating the importance of sea-level feedbacks in stabilizing marine-based ice sheets during retreat. Funded under the Geosciences program, which supports basic research expanding understanding of the integrated Earth system, the University of California, Santa Barbara will combine new late Pleistocene/Holocene relative sea-level data from Scotland with ice sheet and glacial isostatic adjustment...

The National Science Foundation Division of Polar Programs awarded a $132,303 project grant to Columbia University under the Polar Programs federal grant program (CFDA 47.078). The grant will support collaborative research to improve understanding of past variability in glaciation in the Weddell Embayment and Antarctic Peninsula regions. Eleven investigators from seven U.S. institutions and Argentine collaborators will study sediment cores from the International Ocean Discovery Program as well...

The University of California San Diego Scripps Institution of Oceanography will receive $363,261 under a three-year Project Grant from the National Science Foundation Division of Polar Programs. The grant will fund collaborative research titled "Peripheral East Antarctic Ice as a Unique Recorder of Climate Variability During the Last Interglacial" from August 2021 through July 2024. The research aims to strengthen understanding of polar regions by expanding knowledge of climate...

This $304,007 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund a collaborative research initiative led by the University of California, Los Angeles (UCLA) to investigate the disappearance of the Laurentide Ice Sheet over the last 20,000+ years. The researchers will use a state-of-the-art ice sheet system and sea-level model to simulate the complete retreat of the Laurentide Ice Sheet and analyze how dynamic ice discharge processes...

The National Science Foundation Division of Polar Programs awarded a $990,272 project grant to The Trustees of Columbia University in New York City to support 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 to August 31, 2025. The research aims to strengthen understanding of the Greenland Ice Sheet and its response to...

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 $312,259 federal Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project titled "How Much and Why Did Ice Sheets Melt During the Last Interglacial (HISEAS)". The project aims to better understand past ice sheet behavior and climate conditions during the last interglacial period approximately 130,000 to 115,000 years ago, in order to improve predictions of future ice sheet changes and sea level rise....

The National Science Foundation Division of Polar Programs awarded a $176,184 Project Grant to the Trustees of the Colorado School of Mines, doing business as the Colorado School of Mines, to conduct collaborative research on improving projections of future Antarctic sea level rise. The key products and services under this CFDA 47.078 Polar Programs grant include: Integrating paleoglaciological observations from the Holocene period into an advanced ice sheet model (BISICLES) to establish the...
