Fig. 1: Core location of KX97322-4 and the distributions of modern temperature and salinity in the equatorial Pacific.

The main figure shows temperature (color shading) and salinity (black contour) profiles from 40°S to 40°N along 160°E for 0–400 m water depth. Dashed arrows indicate Subtropical Lower Water (SLW), Subtropical Mode Water (STMW), and Subantarctic Mode Water (SAMW). The inset map shows the modern temperature distribution at 150 m water depth (color shading) based on the World Ocean Atlas 2013 dataset20 using Ocean Data View software25. The dashed 28 °C SST isotherm indicates the extent of the western Pacific warm pool (WPWP). The locations of core KX97322-4 (00°02′S, 159°15′E) from this study and previously published cores MD06-3018 (23°00′S, 166°09′E)28 and MD97-2125 (22°34′S, 161°44′E)27 from the southwestern Pacific and TR163-19 (2°15.5′N, 90°57.1′W)67 and ODP 1240 (0°01.3′N, 86°27.8′W)55 from the eastern equatorial Pacific (EEP) are shown.
