Fish debris Nd isotope data and benthic foraminiferal B/Ca ratio and stable isotope data for the MIS M2, MIS 100 and the Last Glacial-Holocene from ODP Site 1267.

Corrected δ18O data includes correction for seawater (equilibrated + 0.64 ‰).The B/Ca ratio (in μmol/mol) of C. wuellerstorfi was converted to [CO₃²⁻] using the species specific core top calibration of Yu and Elderfield (2007). Calcite saturation state was calculated for ODP Site 208-1267 and was quality checked against data generated from core top and Holocene aged sediments not used in the original calibration of Yu and Elderfield (2007). The hydrographic data for ODP Site 208-1267 that was used for carbonate system calculations were gathered from the GLODAP version 2 dataset (Lavuset et al., 2016).
