| contents | Using a large piston corer on the Science-1 vessel during the Warm Pool Subject Cruise in 2008, we recovered Core KX97322-4 (00°01.73′S, 159°14.66′E, 2362 m) from the Ontong-Java Plateau in the central western Pacific warm pool. The sedimentation rate is 0.39-4.95 cm/kyr, with an average time resolution of 0.57 kyr/cm. 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 seven accelerator mass spectrometry radiocarbon (14C) data on the planktonic foraminifer Trilobatus sacculifer (with a sac) (350–500 μm), five data published before and another two new data was performed at NOSMAS and Beta Analytic Inc., USA. We measured stable oxygen isotope and Mg/Ca ratio of planktic foraminifera Globigerinoides ruber, T.sacculifer, Neogloboquadrina dutertrei, Globigerinella siphonifera, Globorotalia crassaformis and Globorotalia truncatulinoides dextral 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 30,000 years, aiming to probe paleo-ENSO progress during the last deglaciation. |
