Age model and Nd/Ca ratio of planktonic foraminifera from sediment core MD05-2925 off the Solomon Sea ...
Abstract: The Intertropical Convergence Zone (ITCZ) encompasses the heaviest rain belt on the Earth. Few direct long-term records, especially in the Pacific, limit our understanding of long-term natural variability for predicting future ITCZ migration. Here we present a tropical precipitation record...
