Project Grant 2207109
- This three-year, $408,968 National Science Foundation project grant funds research at the University of Chicago to improve estimates of ancient ocean pH and atmospheric carbon dioxide concentrations through analysis of boron isotope ratios in halite evaporites. The researchers will investigate boron behavior in halite formations to determine boron hosting phases like fluid inclusions or trace minerals. Experimentally precipitated halites, natural salt cores, and a 36 million year old marine...
- This $374,395 National Science Foundation project grant through the Geosciences program (CFDA 47.050) will fund research at Rutgers University and Princeton University from December 2022 through November 2024. The grant supports the identification of silicate diagenesis processes controlling pore fluid chemistry in marine sediments and their influence on the geochemical budgets of magnesium, strontium, lithium, and boron through analysis of pore fluid samples from the Mid-Norwegian Margin....
- This National Science Foundation Project Grant award of $261,152 will fund a collaborative research project to study reaction pathways in oceanic serpentinites through laboratory experiments from August 1, 2022 to July 31, 2025. The University of Colorado at Boulder will receive the award under the Geosciences program (CFDA 47.050) to conduct quantitative analyses of the alteration of seafloor mantle rocks through serpentinization reactions with seawater. The research aims to better understand...
- 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...
- The Regents of the University of Colorado were awarded a $464,509 Project Grant from the National Science Foundation Division of Earth Sciences under the Geosciences federal grant program (CFDA 47.050). The three-year award, made on August 1, 2023 and set to be completed by July 31, 2026, will support collaborative research into the roles of lithology and water on deep continental crustal rheology using natural field settings and laboratory experiments. The research aims to further fundamental...
- This $711,586 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research at North Carolina State University to analyze thirty years of foraminiferal assemblages from the Santa Barbara Basin. The grantee will create a record of planktic foraminifera abundances from stored samples collected in the basin and connect the results to modern oceanographic measurements and older seafloor sediments. This will improve understanding of how climate change has...
- 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, awarded by the National Science Foundation (NSF) Division of Environmental Biology under the Biological Sciences program (CFDA 47.074) on July 15, 2025, supports a collaborative research initiative totaling $411,079 through June 30, 2030. The primary deliverable is a multi-scale, multi-proxy investigation examining how marine nutrient availability during the Tonian Period (1000-720 million years ago) may have driven eukaryotic diversification and ecosystem transformation. The...
- 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 Project Grant award of $390,694 from the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences program (CFDA 47.050) supports collaborative research to explore the ecology and morphology of the Little Dal reef system in northwestern Canada, which contains some of the earliest purported remains of sponges on Earth. The researchers from the University of Washington and Dartmouth College will utilize a multidisciplinary and multiscale approach, including...
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 record. Additional microanalysis techniques will characterize fossil preservation modes. Models will describe the ancient marine silica cycle. This work will address gaps in understanding the early Paleozoic biological transformation of the silica cycle and marine system responses to climate-driven silicate weathering fluctuations. The research aligns with the NSF Geosciences program's support for basic research expanding knowledge of the integrated Earth system through atmospheric, earth, and ocean sciences. Project outcomes include graduate and undergraduate student research training, science engagement for over 200 elementary school girls, and a museum exhibit on early silica biomineralizers.
