In this session we will discuss how Panamá coral skeletal barium concentration and oxygen isotopic ratios can be used to reconstruct near-monthly resolved changes in river discharge and hydrology in Panamá back to the early 1700s CE. We will then evaluate the implications of the paleohydrology results for understanding El Niño Southern Oscillation (ENSO) effects on Central American drought cyclicity and the long-term management of the Panamá Canal.
