The National Science Foundation (NSF) awarded a $442,114 Project Grant to the University of Texas at Austin under the Geosciences program (CFDA 47.050) to study how pelagic calcifier communities and carbonate production have changed from the early Eocene to the early Oligocene epochs. The research aims to reconstruct changes in the South Atlantic subtropical gyre ecosystem over this period and determine how those changes impacted surface carbonate production and seafloor carbonate burial. The project will generate data on planktic foraminifera and calcareous nannoplankton mass accumulation rates, planktic foraminiferal assemblages, and benthic foraminiferal accumulation rates from sediment cores collected during International Ocean Discovery Program expeditions. This research is intended to improve understanding of the evolution of the global carbon cycle under different climatic regimes. No subawards are planned under this grant, which has an award period from January 1, 2025 to December 31, 2027.
