Description

We present multiproxy data spanning between ~25000 and 3500 calibrated years before the present (cal yr BP) from the eastern Arabian sea (EAS). This is possibly the first record of stable isotope record in pteropods from the EAS. Based on this dataset, we found that the Indian summer monsoon (ISM) was weak during the Last Glacial Maximum (LGM). Moreover, upwelling intensity was high during the early Holocene, which was followed by a significant weakening of ISM during the 4.2 ka event.
