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...
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...
The National Science Foundation (NSF) Geosciences program awarded a $498,356 project grant to the University of Nevada, Reno (UNR) for the project "Controls on Ridgeline Profile Morphology." This 3-year grant, effective July 1, 2024, will fund research to improve the understanding of how ridgelines are shaped and eroded, which is key to predicting natural hazards like landslides, debris flows, and river flooding. The project will test three hypotheses about the controls on ridgeline...
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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $335,489 to Florida State University to conduct collaborative research on depth-dependent decarbonation processes in the Sierra Nevada, California. The research focuses on understanding how high-pressure, high-temperature metamorphism driven by magma intrusion into the Earth's crust can mobilize carbon and other elements, potentially leading to the formation of valuable skarn mineral...
The National Science Foundation (NSF) awarded a $601,138 Project Grant under its Geosciences program (CFDA 47.050) to The Johns Hopkins University to conduct research on the nonlinearity and feedbacks in the atmospheric circulation response to increased carbon dioxide (CO2). The research aims to understand the mechanisms driving differences in circulation changes across climate models and the causes of nonlinear responses, such as the rapid weakening of the Atlantic Meridional Overturning...

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 weathering through field work measuring organic carbon loss in depth profiles of shale formations in California. This field data will be used to calibrate and modify a reactive-transport model to predict CO2 release from shale weathering across spatial and temporal scales. The work addresses a knowledge gap around mechanistic understanding of how physical processes modulate CO2 release and has potential to lead to advances in understanding feedbacks between climate, tectonics, and topography - advancing the goals of the NSF's Geosciences program (CFDA 47.050).
