(Table S1) Nd isotope ratios of sediment core MD99-2198

All reported 143Nd/144Nd ratios have been normalised to the recommended JNdi value of Tanaka et al. (2000). Epsilon Nd values denote the deviation of measured 143Nd/144Nd values from the bulk Earth value (CHUR=0.512638) in parts per 10,000. The external reproducibility (2σSD) is reported based on repeat JNdi analyses of the day. For one sample (13.94-13.95 m), the ion beam was significantly smaller than for standards and hence a propagated error is reported to reflect this difference.
