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 $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 National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award, valued at $642,396, was granted to William Marsh Rice University in Houston, Texas. The project aims to improve understanding of the Earth's water cycle and hydroclimate by integrating data on water isotopes from present-day observations and paleoclimate proxies. Key activities include: Developing the Water Isotopes and Climate Network (WISONET) research platform to provide seamless access to modern...
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 three-year, $1,135,926 National Science Foundation project grant funds research to reconcile hydroclimate model projections and geologic data from a warmer period in the past to improve understanding of future water availability in the Southwestern United States. The awardee, Colorado State University, will collect new stable isotope data from sedimentary carbonates in New Mexico spanning the Middle Miocene Climate Optimum. Analysis of existing climate model simulations will differentiate...
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...
The Massachusetts Institute of Technology (MIT) received a $164,055 Project Grant award from the National Science Foundation (NSF) to conduct research titled "COLLABORATIVE RESEARCH: P2C2--SPELEOTHEM CONSTRAINTS ON SEASONAL HYDROCLIMATE VARIABILITY IN MAINLAND SOUTHEAST ASIA SINCE THE LATE PLEISTOCENE." The grant was awarded on July 1, 2021 with a completion date of June 30, 2024 under the NSF's Geosciences program (CFDA 47.050). Through this award, MIT researchers will work to...
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 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 Project Grant from the National Science Foundation's Division of Atmospheric and Geospace Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $313,105 to President and Fellows of Harvard College to develop a new paleoclimate proxy. Specifically, the award will fund research to quantify the reliability of speleothem magnetization as an indicator of past rainfall by investigating the physical mechanism linking rainfall and deposition of magnetic particles....
