The University of South Florida (USF) received a $441,804 project grant from the National Science Foundation's Geosciences Program (CFDA 47.050) to conduct collaborative research on characterizing Northern Hemisphere atmospheric variability from Central American wind gap-induced upwelling. This 2-year grant, starting on February 1, 2024, will leverage sediment proxy measurements, climate model simulations, and data product examinations to investigate the driving mechanisms behind the variability in Tehuantepec Gap wind strength over paleoclimate timescales. The research aims to provide crucial new insights into glacial-interglacial atmospheric dynamics and the linkages between the Pacific and Atlantic ocean-atmosphere systems. This project will support the work of two early career scientists and provide educational and training opportunities for undergraduate students at USF, which is designated as both a Hispanic-serving and Native American Pacific Islander-serving institution. No sub-awards are planned under this grant.
