Foraminifera cleaning was carried out using the method adopted from Barker et al. 2003. Boron was purified using the micro-distillation method (Misra et al., 2014a). Trace-element analysis (e.g. Mg/Ca) was carried out using the High-Resolution Inductively Coupled Plasma Mass Spectrometer (HR-ICPMS) (Misra et al., 2014b). Boron isotope analysis was carried out using Thermo Neptune Plus multi-collector inductively coupled plasma mass spectrometer (MC–ICPMS), following the method described in Tarique et al. 2021, and Lloyd et al. 2018. Sea surface temperature (SST) was calculated using the foraminifera Mg/Ca utilizing the method adapted from Gray and Evans 2019. Sea surface salinity (SSS) was calculated using the Mg/Ca derived SST, foraminifera d18O and regional seawater d18O and salinity relationship.72.0922229.008889Arabian Sea
