Summary

Neodymium (Nd) isotope data measured from IODP Site U1556 comprises of detailed sample information including 3 depth scales, the normalised 143/144 Nd ratio, the eNd(0) and eNd (t) values for each sample, plus the associated internal errors for normalised 143/144 Nd ratio, the eNd(0). Rare Earth Element (REE) data measured from IODP Site U1556 comprises of detailed sample information including 3 depth scales, mass of fish debris dissolved for each sample, the concentration of Phosphorous (P) and Calcium (Ca) in ppm, and the concentration of REEs in ppb. Additionally, the concentration of REEs has been normalised to the Post-Archean Australian Shale (PAAS) using values from Pourmand et al. 2012 have been included. Ce anomalies have been calculated using 2 similar methods, plus other REE parameters: LREE, MREE, HREE, MREE*, HREE/LREE, and MREE/MREE*. Percentage Calcium Carbonate (%CaCO3) data from IODP Sites U1557 and U1558 including detailed sample information including 3 depth scales where possible, and weight percentage CaCO3 data.
