“…Rather than involving a subtle change, monsoon circulation was more substantially affected, leading to reversed seasonal temperature gradients in the eastern Arabian Sea (sensu (Anand et al, 2008)). Principal support for the notion of large changes in monsoonal circulation during MIS3 comes from the west Pacific warm pool (Stott et al, 2002), north China (Wang et al, 2021) and the Japan Sea (Sagawa et al, 2023), suggesting that the wider Asian monsoon circulation displayed significant variability during MIS 3/4.…”

Abstract. The Asian monsoon system is a crucial part of the global climate system affecting a significant proportion of the world population. Understanding the controls for changes in the monsoon system is crucial for meaningful assessments of future climate change. The Arabian Sea is part of the wider Asian monsoon system and has been studied regarding controls of monsoon variability through time. In this study we present sea surface temperature data from 37–67 ka BP from sediment core NIOP 929 from the western Arabian Sea assessing the importance of northern/southern hemispheric climate change driving monsoon circulation in the Arabian Sea. Earlier work implies a straightforward link between monsoon variation in the Arabian Sea and northern hemisphere millennial scale climate change during glacial periods, as depicted in Greenland ice cores. We present a new millennial-scale Mg/Ca based sea surface temperature reconstruction based on the planktic foraminifera species G. bulloides and G. ruber. We use these data to calculate seasonal sea surface temperatures. The SST data are variable with a maximum short-term change of 8–9 °C. The variations in our SST records appear not related to change in either hemisphere in a straightforward fashion by not showing a phase-locked relation to millennial scale change in Greenland or Antarctic ice core records. We discuss these changes in the context of the Arabian Sea potentially being a “melting pot” with both the northern and the southern hemisphere exerting influence on a seasonal scale.
