This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund collaborative research to develop an integrated framework for understanding the Late Devonian mass extinctions and associated changes in ocean chemistry and climate. The $231,421 award to Texas A&M University aims to: Establish a new geologic framework linking Late Devonian mass extinctions to the formation of epeiric black shale deposits across North and South America using...
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,...
This $172,778 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research to test climate model predictions of hydrologic change in the tropical Atlantic during a past warm period. Specifically, the awardee, Utah State University, will geochemically analyze oxygen isotopes and magnesium-to-calcium ratios in planktonic foraminifera from deep-sea sediment cores at several sites, including Ocean Drilling Project Site...
The National Science Foundation Division of Ocean Sciences awarded $851,808 to the University Corporation for Atmospheric Research under the Geosciences program (CFDA 47.050) for a project grant running from July 1, 2022 to June 30, 2025. The grant will support research analyzing tectonic degassing as a potential driver of the mid-Miocene climate transition approximately 14 million years ago, when the Earth experienced sustained cooling. Key products include new biomarker-based sea surface...
This Project Grant award of $207,480 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research at Utah State University to disentangle paleoclimate signals from individual foraminiferal analyses across the Paleocene-Eocene Thermal Maximum (PETM) event. The goal is to develop new estimates of surface and deep-water warming and carbon cycle dynamics during this important past climate change event by applying advanced analytical techniques to well-preserved...
This Project Grant award, valued at $442,114, was issued by the National Science Foundation (NSF) under the Geosciences Program (CFDA 47.050) to the University of Texas at Austin. The objective of the research is to study how the pelagic calcifier communities in the South Atlantic Subtropical Gyre evolved from the early Eocene to the early Oligocene, and how those changes impacted carbonate production and burial at the seafloor. The project will generate data from sediment cores collected during...
This $269,580 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research at Oregon State University to improve paleoclimate reconstruction in high-latitude regions. The university will develop new and enhanced trace element to calcium paleoproxies for understudied temperate to polar planktic foraminiferal species found in the Northern California Current region. Researchers will establish magnesium to calcium-temperature and sodium to calcium-salinity...
This $293,010 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research at The Ohio State University to develop novel isotope proxies that improve understanding of Earth's climate and carbon cycle dynamics at the onset of the Late Paleozoic Ice Age from 350 to 290 million years ago. The grantee will pair calcium and clumped isotope systems to test hypotheses regarding diagenetic influences on stable carbon isotopes used as proxies for carbon...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) provides $144,969 to Iowa State University of Science and Technology to produce a continuous, annually resolved, and millennial-length marine climate history of the Northeast Pacific Ocean region. The project will utilize paleoclimate proxies from bivalve mollusks, tree-ring chronologies, and tropical coral growth-increment records to reconstruct sea surface temperatures and climate variability in...
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...
