Deep-Ocean temperature and δ¹⁸Oseawater estimates for study sites from the Iberian Margin

Site U1385 PSU Solver (Thirumalai, Quinn and Marino, 2016) deep-water temperature and δ18Oseawater reconstructions and their propagated errors for the past 1.5 Myr are combined over the most recent 0–50 kyr interval with MD01-2444 (Skinner and Elderfield, 2007) and MD99-2334 which is offset by a temperature of +0.6°C to account for its deeper setting (Skinner, Shackleton and Elderfield, 2003). Iberian Margin deep-water (>2500m) benthic δ18O, temperature and δ18Oseawater are referenced to the LR04 timescale. Calibration equations are listed in Thomas et al. (2026) Table 2.
