Project Grant 2202644
- 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 $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...
- The University of New Mexico received a $148,836 Project Grant award from the National Science Foundation Division of Atmospheric and Geospace Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will fund collaborative research to test hypotheses of Mesoamerican hydroclimate over the last several glacial cycles through analysis of stable oxygen isotope ratios in stalagmites from caves in southwest Mexico and Sistema Huatla. The research aims to examine whether...
- 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 $116,693 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research to illuminate fundamental climate processes that influenced terrestrial ecology in western Pangea during Earth's previous icehouse period. Key goals combine paleontology, isotope geochemistry, and magnetostratigraphy to: identify the stratigraphic position of the Carboniferous-Permian boundary in Utah's Cutler Group sedimentary rocks; determine the pace and...
- 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 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 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...
- The National Science Foundation awarded a $330,177 project grant to the Massachusetts Institute of Technology for collaborative research titled "High Temporal Resolution Paleomagnetism of Speleothems." The award period is from April 15, 2021 through March 31, 2024. The funding supports the Geosciences program, which aims to expand fundamental knowledge of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Specifically, the grant will fund...
- The University of Michigan will receive $331,413 under a three-year Project Grant from the National Science Foundation Division of Earth Sciences to develop precipitation, evaporation and temperature records from tropical lake sediments and cave deposits for the last 700,000 years. The grant will support basic research in the atmospheric, earth, and ocean sciences under the Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through...
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 will analyze subsamples from Carlsbad Cavern, Lechuguilla Cave, Wind Cave, Mammoth Cave, Mystery Cave, and caves in New York dating to periods including the Middle Holocene, Younger Dryas, Last Glacial Maximum, and Last Interglacial. The work will characterize temperature gradients between sites and provide two graduate students with research training. By generating new paleotemperature records, this NSF-funded research aims to benchmark climate models and evaluate climate impacts on hydroclimate and water resources.
