Summary
Abstract: A detailed reconstruction of West African monsoon hydrology over the
past 155,000 years suggests a close linkage to northern high-latitude
climate oscillations. Ba/Ca ratio and oxygen isotope composition of
planktonic foraminifera in a marine sediment core from the Gulf of
Guinea, in the eastern equatorial Atlantic (EEA), reveal centennial-
scale variations of riverine freshwater input that ... View entire text
