This $129,726 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research project to develop a 500,000-year speleothem growth history near the southern margin of the Laurentide Ice Sheet in New York State. The research aims to determine if the ice sheet reached New York during each of the past five ice ages, which will provide insights into the consistency of ice sheet response to climate change drivers and improve estimates...
This Project Grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $136,778 to support collaborative research on constraints of global mean sea level and fingerprinting polar ice mass flux from coastal cave records. The research aims to advance knowledge of global mean sea level variations and characterize the relative contribution of ice sheets and glaciers over the last 130,000 years....
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 $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...
This $786,904 National Science Foundation project grant supports research to measure absolute paleo-surface temperatures for important past climate periods in the southwestern and northern United States. Funded under the Geosciences program (CFDA 47.050), the award will provide quantitative paleoclimate reconstructions using dual clumped isotope and strontium isotope analyses of speleothem samples from multiple caves. Researchers from the University of New Mexico and the University of Michigan...
This National Science Foundation Project Grant, awarded under the Geosciences program (CFDA 47.050), provides $190,000 to resolve high-resolution paleoclimate variability in subarctic Canada across the mid-Pleistocene transition and interglacial periods of the last 1.5 million years. The postdoctoral researcher will characterize past interglacial climate variability using rare subarctic speleothems, combining novel geochronological techniques, micro-analytical methods, and imaging to reconstruct...
This Project Grant from the National Science Foundation's Office of Integrative Activities, under the Integrative Activities federal grant program (CFDA 47.083), provides $139,022 to Plymouth State University from January 15, 2023 through December 31, 2024. The funding will support research to reconstruct past climate records in New England from 13,000 years ago when a large ice sheet was retreating, through analysis of organic molecules in lake sediments. The research aims to elucidate the role...
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 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 $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...
