This $201,294 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research into carbon cycle feedbacks during the Paleocene-Eocene Thermal Maximum. The grantee, Regents of the University of California at Riverside, will generate new records of ocean chemistry and develop novel modeling strategies to quantify global carbon cycle responses during this past period of warming. A postdoctoral researcher at UC Santa Cruz and undergraduate interns from UC...
This Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support a $180,000 postdoctoral fellowship to apply the "triple oxygen isotope" method to study changes in aridity across the Paleocene-Eocene Thermal Maximum (PETM) in the Bighorn Basin of Wyoming. The goal is to test whether this new analytical approach can detect shifts in water availability during this past period of global warming, which could improve models for predicting future...
This $169,869 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will support the development of an intermediate complexity Earth system model to simulate the cycling of carbon dioxide and methane between vegetation, soils, the atmosphere, and oceans during the Paleocene-Eocene Thermal Maximum, approximately 56 million years ago. The Regents of the University of California at Riverside will couple representations of the terrestrial and marine carbon cycles...
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 Project Grant award of $172,793 was provided by the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences program (CFDA 47.050) to support a collaborative research project. The goal is to study a geological core sample from the U.S. Midwest that provides a record of the dramatic climate transition from a glacial "icehouse" period to a severe "hothouse" period approximately 300 million years ago, culminating in the largest mass extinction...
This $419,234 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to study the effects of climate change on mammalian functional diversity over long timescales. Key objectives include: Analyzing changes in mammal functional diversity, floral composition, and abiotic factors like temperature before, during, and after the Paleocene-Eocene Thermal Maximum (PETM) climate event in the Bighorn Basin, Wyoming. This will elucidate the...
This $163,915 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project investigating changes in carbon uptake and storage in the Pacific Ocean during the Pliocene, a warm period approximately 3 million years ago. The primary objectives are to quantify the marine carbon response to temperature-sensitive mechanisms within the ocean, with the goal of better predicting carbon storage during future climate warming. The...
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 Project Grant from the National Science Foundation (NSF) Division of Earth Sciences, under the Geosciences program (CFDA 47.050), will support a collaborative research project to examine how terrestrial ecosystems were rebuilt following the Cretaceous/Paleogene mass extinction event approximately 66 million years ago. The $234,197 award, with a project period from September 1, 2023 to August 31, 2028, will fund paleontological and geochemical analyses of fossil collections and new field...
This $303,642 National Science Foundation project grant will fund research to quantify global carbon cycle feedbacks during the Paleocene-Eocene Thermal Maximum, a past period of global warming. Led by the University of California Santa Cruz, the research team will measure how volcanism contributed to atmospheric carbon dioxide rise during this event and constrain total carbon emissions through new ocean acidification records. They will also develop novel carbon cycle modeling to compare...
