Short summary
Short summary
The deep ocean is an important part of the global climate system. Accurate estimates of temperature changes at depth are crucial to understand the role of the intermediate to deep ocean in climate change. We have used samples from the Indian Ocean to establish Mg/Ca-based temperature calibrations based on benthic foraminifera. Our data suggest that generating optimal Mg/Ca ratios in benthic foraminifera may require species- and region-specific cleaning procedures.

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.
