Climatic controls on central African hydrology during the past 20,000 years

Article Abstract:

The isotopic composition of terrigenous plant lipids, extracted from a marine sediment core-close to the Congo River mouth is analyzed to reconstruct past central African rainfall variations and compare this record to sea surface temperature changes in the South Atlantic Ocean. Results reveal changes in ocean circulation, and hence sea surface temperature patterns, were important in modulating atmospheric moisture transport onto the central African continent.
