| contents | We obtained Core KX97322-4 (00°01.73′S, 159°14.66′E, 2362 m) from the Ontong Java Plateau in the central WPWP using a giant piston corer on the Science-1 vessel during the Warm Pool Subject Cruise executed in 2008. The sedimentation rate is 0.39–4.95 cm kyr^-1^, with an average time resolution of 0.57 kyr cm^-1^. The age model was established based on downcore stable oxygen isotope measurements on the benthic foraminifer Cibicidoides wuellerstorfi (>500 μm) correlated with the reference benthic stack LR04 using Match 2.3.1 software, combined with five accelerator mass spectrometry radiocarbon (^14^C) dates on the planktonic foraminifer Trilobatus sacculifer (with a sac) (350–500 μm) measured at the National Ocean Sciences Accelerator Mass Spectrometry facility, Woods Hole Oceanographic Institution, USA. We measured stable oxygen isotope and Mg/Ca ratio of planktic foraminifera Globigerinoides ruber and Neogloboquadrina dutertrei at the Institute of Oceanology, Chinese Academy of Sciences (IOCAS), using GV IsoPrime mass spectrometer and inductively coupled plasma-optical emission spectrometry (ICP-OES, Thermo-Fisher, iCAP6300 radial) to rebuild paleo-temperature and salinity of the central western Pacific warm pool during the last 360, 000 years, aiming to probe paleo-ENSO progress in late Quaternary. |
