This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $162,339 to Trustees of Boston College, doing business as Boston College, for a research project titled "Developing a 500 kyr Speleothem Growth History near the Southern Laurentide Ice Sheet Margin in New York State." The project will use speleothem (cave formation) data to determine if the Laurentide Ice Sheet advanced to near its Last Glacial Maximum extent during each of...
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 $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 $234,972 National Science Foundation project grant, awarded under the Geosciences program (CFDA 47.050), will fund research to develop new paleotemperature records for North America. The University of Michigan, in collaboration with the University of New Mexico, will analyze cave deposits known as speleothems collected from various caves across the continental U.S. Using clumped isotope and strontium isotope analyses on approximately 200 mg subsamples, the researchers aim to determine...
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...
This $146,450 National Science Foundation project grant supports collaborative research to reconstruct speleothem proxy records from Central Texas during past abrupt global change events between 16,000-11,000 years ago. The research team, led by Rice University, will analyze seven coeval speleothems spanning a 375-kilometer transect to discern changes in moisture sources and the location of wet-dry gradients. The speleothem records will be compared to proxy system models and climate models to...
This three-year, $109,644 project grant from the National Science Foundation Division of Earth Sciences aims to advance understanding of abrupt climate change through reconstructing fluctuations of a late-glacial ice mass in eastern North America. Funded under the Geosciences program (CFDA 47.050), the University of Arizona will lead efforts to determine the role of seasonality in abrupt climate shifts by mapping glacial landforms and dating the pattern and timing of recession for an ice cap...
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...
The University of South Florida was awarded a $537,362 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) for the period of July 1, 2022 to June 30, 2025. The grant aims to advance understanding of global mean sea level variations over the last 130,000 years through geological records preserved in coastal cave deposits from multiple locations. Researchers will reconstruct past sea level history and study sea level high stands during prior warm periods. They...
This three-year, $384,577 project grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will support collaborative research to construct robust temperature and ice volume histories during the late Cretaceous and Cenozoic periods (approximately 77-0 million years ago). The University of Rochester will utilize benthic foraminiferal test compositions from sea floor sediments to develop proxy records of deep ocean temperatures,...
