This data set contains a compilation of records of sea-surface and thermocline temperatures, derived from planktonic foraminifera Mg/Ca, for the Indo-Pacific Warm Pool (ranges 14.8°N-13.1°S, 115.2°E-158.0°E) over the past 25,000 years. It contains two sets of data-sheets (six sheets). Set 1: the mean anomaly stacks of sea-surface temperature anomaly )(SSTA, sheet 1), thermocline water temperature anomaly (TWTA, sheet 2), oxygen isotope composition of Globigerinoides ruber (Gr-A, sheet 3) and surface water oxygen isotope composition (Δδ18Osw, sheet 4) of IPWP over the last 25 ka. Set 2: the records of Mg/Ca and calibrated temperatures of Cores MD10-3340 (0.52°S, 128.72°E, sheet 5), SO18480 (12.06°S, 121.65°E, sheet 6) and KX21-2 (1.42°S, 157.98°E, sheet 7) firstly reported in this study.
