Description:
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.
