(Table S2, Figure 3a) Sr-Nd isotopic compositions of sediment cores drilled during MSM20/3@en

SPS + Numbers: measured at CPGeo, University of São Paulo; Numbers: measured at the Laboratory of Geochronology, University of Brasília. The ages are calibrated by the available 14C-AMS dates (i.e. core GeoB16206-1 and GeoB16224-1), while others (i.e., late Holocene, Mid-Holocene ) are roughly estimated by 14C-constrained age model of sediment cores nearby and/or water depth at which the sediment core was raised.SPS及数值数据：于圣保罗大学CPGeo实验室测定；数值数据单独于巴西利亚大学地质年代学实验室测定。 部分测年数据通过已有的14C加速器质谱测年（14C-AMS）结果（即岩芯GeoB16206-1与GeoB16224-1）完成校准；其余测年数据（如全新世晚期、全新世中期）则依托邻近沉积物岩芯的14C约束年代模型，并结合沉积物岩芯获取处的水深数据进行粗略估算。
