- This $471,604 National Science Foundation project grant will fund research into the origin and expansion of silica biomineralization and its influence on the global silica cycle from 520-440 million years ago. The Regents of the University of Colorado will conduct stable isotope analysis of silicon in the oldest fossils of sponges and radiolarians from western United States geological sites. Researchers will evaluate isotope preservation and build an improved Cambrian-Ordovician silica isotope...
- This $850,918 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to characterize the role of reverse weathering reactions on marine silicon (Si) and lithium (Li) isotope mass balances. The research aims to develop Si and Li isotope ratios as proxies to better understand modern reverse weathering reactions and their impacts on the carbon cycle. Key activities include: Analyzing archived sediment and porewater...
- 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, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), will fund collaborative research to characterize the role of reverse weathering reactions on marine silicon (Si) and lithium (Li) isotope mass balances. The total award amount is $275,425 and the project period runs from July 15, 2024 to June 30, 2027. The research will study reverse weathering signatures within major sediment depocenters, such as the Amazon Delta, French Guiana Mobile...
- 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 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $374,314 to Yale University to investigate changes in carbon uptake and storage in the Pacific Ocean during the Pliocene era, around 3 million years ago, as an analog for understanding the ocean's response to modern climate warming. The researchers will use data and models to quantify the impacts of temperature-sensitive mechanisms, such as circulation changes and biological processes,...
- 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...
- Federal Grant Award Summary The National Science Foundation's Division of Earth Sciences awarded a $399,996 Project Grant to the Colorado School of Mines (effective September 1, 2025 through August 31, 2028) under the Geosciences program (CFDA 47.050) to conduct collaborative research on paleoclimate responses to consecutive warming events. The primary deliverables include a novel terrestrial dataset quantifying climate changes and Earth system responses across more than ten consecutive...
- Federal Project Grant Award Summary The National Science Foundation's Division of Ocean Sciences awarded $433,991 to the University of South Florida under the Geosciences program (CFDA 47.050) on October 1, 2025, for a collaborative research project examining deep Indian Ocean carbon storage during the Last Glacial Maximum. The primary deliverable is peer-reviewed scientific research investigating whether abnormally old carbon accumulated in the deep Indian Ocean approximately 18,000 years...
This National Science Foundation (NSF) Geosciences program (CFDA 47.050) Project Grant awards $362,421 to Utah State University for a five-year research initiative (April 1, 2026–March 31, 2031) examining the ancient carbon cycle through analysis of siliceous deep-sea sediments. The primary research deliverable is a new proxy methodology using germanium/silicon (Ge/Si) ratios in microfossils, particularly radiolarians, to constrain ancient silicate weathering rates. The project will generate calibration data from modern sediments, establish down-core records from International Ocean Discovery Program cores spanning two key paleoclimate events—the Paleocene-Eocene Thermal Maximum (56 million years ago) and the Middle Eocene Climatic Optimum (40 million years ago)—and produce scientific findings that advance understanding of how silicate weathering feedbacks regulate Earth's climate system under warming conditions. The award includes substantial educational and outreach deliverables aligned with NSF's workforce development priorities. Utah State University will develop novel K-12 through PhD-level classroom and field experiences, and will create an interactive museum exhibit at the Loveland Living Planet Aquarium introducing the public to plankton and deep-sea fossils. The research outcomes will produce peer-reviewed publications, datasets characterizing Ge/Si trends across paleoclimate transitions, and methodological advances applicable to paleoclimate reconstruction, ultimately supporting improved predictive models of silicate weathering's role in regulating future climate.
