Stable isotopic variations in foraminiferal test from Arabian Sea and its relation to the annual south-west monsoonal rainfall over the Indian subcontinent

Examination of delta 18O estimations from the planktonic foraminifera, Globigerinoides ruber, collected at fortnightly intervals using deep sea sediment traps moored at depths of 1000 and 2787 m in the Eastern Arabian Sea (15 degrees 28'N and 68 degrees 45'E) shows very little variation du...
