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...
This federal Project Grant award of $355,024 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research effort to reconstruct the collapse of the Cordilleran Ice Sheet in western Canada since the last ice age. The project aims to determine the timing and rate of the ice sheet's disappearance over the past 10-20 thousand years through geologic dating of rock samples and computer modeling. By improving understanding of past ice sheet changes, the...
This $204,782 federal Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support a collaborative research project to determine when and how quickly the Cordilleran Ice Sheet in western Canada disappeared since the end of the last ice age. The project will create a 3-D reconstruction of the ice sheet's collapse by collecting and dating rock samples across the region. This data will be used in computer models to simulate the ice sheet's past...
This $696,926 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) funds collaborative research between the University of New Mexico, University of South Florida, and Harvard University to advance understanding of global mean sea level variations and the relative contributions of polar ice sheets and glaciers. The researchers will use geological records preserved in coastal cave deposits to reconstruct global mean sea level history over the past 130,000 years...
This Project Grant award of $261,875 from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) supports a collaborative research project to study Antarctic ice margin dynamics by analyzing ice-rafted debris in sediment cores from the Southern Indian Ocean. The research team, led by the University of Delaware, will use the sediment records to reconstruct changes in Antarctic glacial activity over time, particularly focused on understanding how variations in Earth's orbital...
This $248,000 Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will support a collaborative research project to investigate past Arctic sea ice coverage and its impacts on marine ecosystems. The research team at 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 warm periods....
This three-year, $1.2 million Project Grant from the National Science Foundation Division of Earth Sciences aims to test the role of seasonality in abrupt climate change through reconstructing fluctuations of a late-glacial ice mass in eastern North America. Under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences, the University of Maine will collaborate with researchers to determine the signature of summer warming-driven ice retreat...
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 $221,255 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research to better understand spatial variability in sea level change during the last interglacial period approximately 120,000 years ago. The grantee will develop high-resolution global models of mantle flow to predict dynamic topography change across the greater Caribbean region over this timeframe. They will also compile a comprehensive dataset of interglacial sea level indicators...
This $200,000 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research at the University of Michigan from September 2022 to August 2025 to investigate the importance of sea-level feedbacks in stabilizing marine-based ice sheets during retreat. The research will combine new late Pleistocene/Holocene relative sea-level data from Scotland with glacial isostatic adjustment models to understand sensitivity of the former Minch Ice Stream to local...

This $793,146 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project titled "How Much and Why Did Ice Sheets Melt During the Last Interglacial (HISEAS)". The project aims to better understand how Greenland and Antarctic ice sheets responded to past periods of natural warming, in order to improve predictions of future ice sheet behavior under climate change.

The research will involve a combination of fieldwork to obtain new estimates of past sea levels, laboratory analyses to reconstruct past climate conditions, and modeling to simulate data-informed histories of sea level, ice sheets, and climate. Key deliverables include a comprehensive database of paleoclimate data, new paleoclimate records, and new sea-level records from four locations. The data-calibrated models will allow the researchers to evaluate the roles of various external and internal factors in driving ice sheet changes during the last interglacial period about 130,000 to 115,000 years ago. This research is expected to contribute to international climate change assessment efforts through the Intergovernmental Panel on Climate Change (IPCC).
