Short summary
Our study is aimed at understanding the processes driving seasonal monsoonal change in the Arabian Sea in relation to the well-known millennial-scale climate change dominating during glacial periods. Our results suggest that sediments from the Arabian Sea have chronicled influence from both the Northern Hemisphere and the Southern Hemisphere. This suggests that the Arabian Sea is potentially a “melting pot” with periodically alternating hemispheric influence affecting monsoon circulation in the region.
