(Table S3) Nd isotopes of sediment core OCE326-GGC6 unclean foraminifera

Neodymium isotopes were analysed using the Nu Plasma HR multi-collector mass spectrometer (MC-ICPMS) at the University of Cambridge, using bracketing of JNdi-1 for standard correction. 146Nd/144Nd was normalised to 0.7219. Reported 143Nd/144Nd are for 30 ratios and the error reported is the internal error of the analysis (2 sigma). The epsilon-Nd is reported with respective external errors (2 sigma) for that particular session, unless the internal error was larger than the external, in which case the combined internal and external error (2 sigma) is reported.本研究于剑桥大学使用Nu Plasma HR型多接收器电感耦合等离子体质谱仪（MC-ICPMS）开展钕同位素分析，采用JNdi-1标准进行夹样校正。将146Nd/144Nd比值归一化至0.7219。本次报告的143Nd/144Nd比值共30组，报告误差为分析内部误差（2σ，即两倍标准偏差）。ε钕（epsilon-Nd）值随对应单次分析批次的外部误差（2σ）一并公布；若内部误差大于外部误差，则采用内部与外部误差结合后的总误差（2σ）进行报告。
