This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports fundamental research to understand the hydrological cycle and rainfall patterns in northern South America during the Pliocene epoch, approximately 5.3 to 2.6 million years ago. The $349,971 award to Brown University will generate and analyze new sediment core data on hydrogen isotopic composition to detect paleoclimate changes and test hypotheses about the mechanisms governing Pliocene-Pleistocene rainfall regimes. The research aims to provide insights into tropical rainfall and water resources that could help regional water managers prepare for future climate conditions. The award also supports the development of climate literacy lesson plans for elementary students and outreach materials in both English and Spanish to disseminate the research findings. No sub-awards are planned under this grant.
