Title: Late Quaternary Climatic Record in Western Equatorial Atlantic Sediment
Abstract: Ten cores contain successions of planktonic foraminiferal assemblages and sedimentary components that record late Quaternary climatic changes in the western equatorial Atlantic Ocean. The climatic cooling that began at the end of the last interglaciation (X zone) and continued throughout the last glaciation (Y zone) led to the sequential disappearance of tropical Globorotalia menardii flexuosa, Globoquadrina hexagona, and Pulleniatina obliquiloculata and the incursion of cool-water Globoquadrina dutertrei, Globorotalia truncatulinoides, G. inflata, and Globigerina bulloides. Despite a twofold increase in cool equatorial species, a tropical climate prevailed throughout the last glaciation. Paleotemperature estimates derived by factor analysis and...
