Project Grant 1339228

This three-year, $643,366 project grant from the National Science Foundation Division of Earth Sciences will support research into understanding the spatial and temporal variation in community assembly processes through leveraging ecological modeling, functional ecology, and the fossil record of small mammals over the late Quaternary period (past 21,000 years). Specifically, the University of California, Merced will conduct a comprehensive re-assessment of existing small mammal fossil records,...

This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $248,863 to the Massachusetts Institute of Technology for research entitled "Collaborative Research: Ear Climate - Pairing Calcium and Clumped Isotopes to Inform Carbon Cycle and Climate Dynamics at the Onset of the Late Paleozoic Ice Age." The research will develop novel isotope proxies to understand the role of land plant evolution on organic carbon burial, atmospheric carbon dioxide,...

The Research Foundation of the City University of New York was awarded a $117,873 Project Grant from the National Science Foundation Division of Earth Sciences. The grant will fund a collaborative research project titled "Collaborative Research: Paleoenvironmental and Paleoecological Responses to Climate Change in the Early Eocene Climatic Optimum" from August 1, 2021 through July 31, 2024. The project aims to strengthen understanding of the integrated Earth system through basic...

This $359,809 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research effort between a U.S. modeling expert and a Swiss geochemistry expert to reconcile climate models and proxy data interpretations for the Miocene period (23-5 million years ago), a time of much warmer global temperatures and higher greenhouse gas levels. The project aims to develop novel proxy system models to better understand how paleoclimate proxies...

This NSF Integrative Activities (CFDA 47.083) Project Grant award to Brown University provides $270,794 to support research on the role of deep ocean equilibration in warmer climates. The project aims to: Perform long-running climate model simulations (over 6,000 years) to better understand the equilibrium responses of the deep ocean under elevated CO2 conditions, as seen during the Middle Miocene Climate Optimum around 15 million years ago. Compare the simulated Miocene ocean conditions with...

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 National Science Foundation Project Grant award of $1,086,964 provides funding to Brown University from July 1, 2022 through June 30, 2025 to develop improved reconstructions of global temperatures during the Miocene climate transition approximately 14 million years ago. The award is made under the Geosciences program (CFDA 47.050) to strengthen understanding of integrated Earth system processes through basic research in atmospheric, earth, and ocean sciences. Specifically, the university...

This $106,572 federal Project Grant award from the National Science Foundation's Integrative Activities (CFDA 47.083) program supports research to improve climate reconstructions and quantify the preservation of organic biomarkers in marine sediments. The primary awardee, President and Fellows of Middlebury College, will employ a latitudinal transect of existing sediment cores from the Line Islands region of the equatorial Pacific to investigate how variations in bottom water oxygen conditions...

This two-year, $162,846 project grant from the National Science Foundation's (NSF) Polar Programs will fund research to improve paleoclimate reconstructions from planktic foraminifera in the polar North Atlantic. The Trustees of Columbia University in the City of New York (Columbia University) will develop new analytical techniques to better interpret climate signals recorded in the shells of Neogloboquadrina pachyderma, a species of foraminifera abundant in high-latitude sediments....

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...
