This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award totaling $567,283 provides funding to the University of Arizona (Arizona Board of Regents) from August 1, 2024 to July 31, 2027 to study the fate of subducted carbonate platforms in the Earth's sub-arc mantle. The key objectives are to: Obtain geochemical and isotopic data on subducted marbles to identify potential signatures in arc volcanic rocks, indicating the source of the subducted carbon. Conduct...
This Project Grant award of $463,475.00 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to investigate calcium isotope variations in ocean island basalts (OIBs) to better understand the deep Earth carbon cycle. The research aims to distinguish mantle source heterogeneity from magmatic processes that control calcium isotope signatures in OIBs. Key objectives include tuning phase equilibrium models to constrain magmatic processes, mantle source...
This Project Grant award, totaling $226,865.00, was provided by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of Delaware. The purpose of the award is to collect high-resolution carbon isotope data on GO-SHIP cruises in the Indian and Pacific Oceans in order to better constrain ocean carbon uptake and storage. Specifically, the project will measure the ratio of carbon-13 to carbon-12 in dissolved inorganic carbon in seawater using a new, less expensive...
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 awarded a $174,000 Project Grant to researchers at the California Institute of Technology to develop a high-resolution record of mantle-derived rocks. The two-year award, made under the Geosciences program (CFDA 47.050), will support efforts to constrain mantle stirring rates and tectonic regimes through analysis of neodymium and samarium isotope ratios in rocks. The Geosciences program aims to expand fundamental earth science knowledge and understanding of the...
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 totals $345,538 to develop a high-throughput/high-sensitivity, in situ 14C extraction line for use in U.S. earth sciences. Funded under the Geosciences program (CFDA 47.050), the grant will support basic research in atmospheric, earth, and ocean sciences through the expansion of knowledge and understanding of the integrated Earth system. Specifically, the Trustees of Columbia University in New York will receive...
This Project Grant award, totaling $284,622, was provided by the National Science Foundation (NSF) under the Geosciences program (CFDA 47.050) to The Trustees of Columbia University in the City of New York, doing business as Columbia University. The award aims to advance the calibration of an existing proxy method for measuring carbonate ion concentration in seawater, which can provide insights into past changes in atmospheric CO2 levels and the global carbon cycle. The key activities involve...
This $162,061 Project Grant was awarded by the National Science Foundation's (NSF) Directorate for Geosciences (CFDA 47.050 - Geosciences) to The Trustees of Princeton University to conduct a collaborative, multi-disciplinary research effort. The project aims to investigate the processes that shape climate and biotic recovery following major carbon cycle perturbations caused by large igneous province volcanism events. Key objectives include developing high-resolution records of volcanism and...
This $1,006,501 federal Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will support a collaborative research effort to understand the processes that shape climate and biotic recovery following major carbon cycle perturbations driven by large igneous province volcanism. The project aims to develop high-resolution records of volcanism, climate, and weathering, and to integrate these with models of mantle geodynamics, magma transport, and outgassing....
