(Table 6) Nd isotope ratios of fish teeth, acetic acid, HH, and residue fractions of sediments from the Atlantic Ocean@en

JNdi-1 was run several times during each day of analyses for standardization on the Nu MC-ICPMS. The offset between the daily average JNdi-1 143Nd/144Nd value and the long term value from the TIMS (0.512103±0.000014, 2 sigma) was then used to normalize each individual analysis.为在Nu多接收电感耦合等离子体质谱仪（Nu MC-ICPMS）上完成分析校准，每日的分析批次中均会多次运行JNdi-1标准物质。随后以每日平均JNdi-1的143Nd/144Nd比值与热电离质谱仪（Thermal Ionization Mass Spectrometry，TIMS）给出的长期参考值（0.512103±0.000014，2σ）之间的偏差，对每一次单独分析结果进行归一化校正。
