| contents | Sediment core SK-312/12 was collected from the Equatorial Indian Ocean at 3750m b.s.l.. Stable oxygen isotopic analysis of Trilobatus sacculifer (w/s) was carried out in 250-355µm size fraction. Mg/Ca analysis of Trilobatus sacculifer (w/s) (250-355µm) was carried out following the cleaning protocol developed by Barker et al. 2003, the method for foraminiferal Mg/Ca analysis. Paleotemperature was reconstructed using the equation: Mg/Ca (mmol/mol) = 0.24 * exp(0.097T), given by Hollstein et al., 2017. The seawater oxygen isotopic record was obtained using the equation: T (⁰C) = 17 – 4.52 (δ18Ocarb - δ18Osw) + 0.03 (δ18Ocarb - δ18Osw)2, given by Erez & Luz, 1983. Paleosalinity was reconstructed using the equation: δ18Osw (VSMOW) = -8.89 + 0.27 * Ssw, given by Srivastava et al., 2007. |
