Dole effect in the north of the South China Sea from sediment core PC27 and PC83@en

Relative intensity proxy (RPI) be constructed using the equation: RPI=NRM/SIRM (20-60)mT * MDFSIRM-CM/MDFSIRM, where MDFSIRM-CM is the center of mass of MDFSIRM. Dole effect was calculated following the method (delta18Oatm - delta18Osurf) of Huang et al. (2020; doi:10.1126/sciadv.aba4823) and Extier et al. (2018; doi:10.1016/j.quascirev.2018.02.008).相对强度代用指标（Relative intensity proxy, RPI）基于下述公式构建：RPI = NRM / SIRM(20~60 mT) × (MDFSIRM-CM / MDFSIRM)，其中NRM为自然剩余磁化强度（Natural Remanent Magnetization），SIRM为饱和等温剩余磁化强度（Saturation Isothermal Remanent Magnetization），MDFSIRM-CM为MDFSIRM的质量中心。 多尔效应（Dole effect）参照Huang等人（2020；DOI:10.1126/sciadv.aba4823）与Extier等人（2018；DOI:10.1016/j.quascirev.2018.02.008）提出的(δ¹⁸Oatm - δ¹⁸Osurf)计算方法进行测算。
