Project Grant 2141520
- This three-year, $378,521 National Science Foundation Project Grant to the University of Nevada, Reno will support research examining the physical controls on carbon dioxide release from shale weathering. The goal is to advance understanding of an important natural control on Earth's climate and provide a framework to improve climate change predictions. Specifically, the researchers will quantify how variations in physical erosion rate, precipitation rate, and local topography influence shale...
- 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...
- 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...
- This Project Grant from the National Science Foundation Division of Earth Sciences provides $174,000 to study the connections between silicate weathering and organic carbon cycling in watersheds within the Upper Deschutes Basin in Oregon from September 2021 through August 2023. The grant supports basic research under the Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through atmospheric, earth, and ocean sciences. Specifically, the...
- This $372,598 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to incorporate stream biogeochemistry into carbon assessment models for enhanced rock weathering, a carbon dioxide removal approach. The project aims to add biological processes like photosynthesis and respiration into a dynamic river network model to better quantify the fate of bicarbonate generated through enhanced rock weathering. This will help identify river...
- This $318,666 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) supports research at Carleton College to evaluate carbon sequestration through enhanced weathering in agricultural soils. The three-year field trial will test the carbon removal efficiency and benefits to crops and soils from annual applications of crushed silicate minerals. The investigator will monitor experimental treatments including locally occurring crushed basalt and an industrial slag...
- 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 $398,984 Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to quantify the biophysical, physiological, and phenological impacts of increasing carbon dioxide (CO2) levels on vegetation and their effects on future climate change. The research utilizes the Community Earth System Model to examine the direct impacts of CO2 fertilization and stomatal closure, as well as the indirect effects of a longer growing season, on...
- The National Science Foundation awarded a $306,062 Project Grant to Princeton University under the Geosciences program (CFDA 47.050) to conduct collaborative research from April 2022 through March 2025. The research aims to advance understanding of cohesive sediment transport through multiscale experiments and numerical simulations. Specifically, the university will combine nano- to microscale imaging and molecular dynamics simulations, micro- to mesoscale millifluidic experiments and...
- The National Science Foundation awarded a three-year $336,534 Project Grant to the University of Colorado Boulder under the Geosciences program (CFDA 47.050) to support collaborative research on the role of extreme rainstorms and hydroclimatic regimes on arid escarpment retreat and sub-cliff slope evolution. The research funded through this award will strengthen understanding of integrated Earth system processes through basic research in atmospheric, earth, and ocean sciences as outlined under...
This $258,177 National Science Foundation Project Grant supports research at Rice University to advance understanding of the physical controls on carbon dioxide release from shale weathering and its influence on Earth's climate. The three-year award under the Geosciences program (CFDA 47.050) will fund collection of field data on the loss of organic carbon in shale depth profiles at sites in California with varying erosion and precipitation rates. Researchers will measure profiles up to 10 meters deep focusing on Monterey, Rincon, and Cozy Dell shale formations where an erosion gradient allows assessment of how variation in erosion influences weathering. Supplemental data from Monterey shale sites with differing precipitation will also be gathered. Field results will calibrate and modify an existing reactive transport model to predict CO2 release from shale weathering under different physical conditions globally. Linking geomorphic transport laws with biogeochemical models in this way presents new opportunities to advance knowledge of the geologic carbon cycle and its feedbacks with climate, tectonics, and topography through this NSF-supported research.
