Continuous data of Globigerinoides ruber calcite delta18O and delta13C versus PDB at ODP Site 969

Samples were obtained from either those taken aboard JOIDES Resolution during Leg 160 or in the Bremen Ocean Drilling Program (ODP) Core Repository. On the ship, approximately one-quarter of a core in sapropel intervals and the surrounding sediments was sliced off the working halves, wrapped in plastic, and stored frozen until shipping. In the shore-based laboratory, the quarter cores were cut in 1-cm subsamples and freeze dried. Samples taken in the Core Repository consisted of 1-cm sediment intervals across sapropels and adjoining sediments collected with plastic scoops, which were also freeze dried upon arrival in Warnemünde. For each sample, we calculated the revised meters composite depth (rmcd) below seafloor based on the tables provided by Sakamoto et al. (1998).
