(1991) for the Northeast Pacific sediment core Y70-5-64 dataset https://doi.org/10.1594/PANGAEA.997246 2026-09-23T05:11:37 We were unable to locate a data table so the data were extracted from Figure 4a in Zahn et al. (1991). The figure was scanned and data optically resolved into an age-CaCO3% data set to 728 ka. Ages were established by Zahn et al. (1991) by correlation to oxygen isotope profiles.
