We obtained Core KX97322-4 (0 deg. 01.73'S, 159 deg. 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^. 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).","onlineResourceLink":"https://www.ncei.noaa.gov/access/paleo-search/study/34576","difMetadataLink":"https://www.ncei.noaa.gov/pub/data/metadata/published/paleo/dif/xml/noaa-ocean-34576.xml","isoMetadataLink":"https://www.ncei.noaa.gov/pub/data/metadata/published/paleo/iso/xml/noaa-ocean-34576.xml","originalSource":null,"dataTypeInformation":"https://www.ncei.noaa.gov/products/paleoclimatology/paleoceanography","studyCode":null,"scienceKeywords":["Sea Surface Temperature Reconstruction"],"reconstruction":"Y","contributionDate":"2021-11-22","entryId":"noaa-ocean-34576","earliestYearBP":356650,"mostRecentYearBP":2760,"earliestYearCE":-354700,"mostRecentYearCE":-810,"publication":[{"author":{"name":"Shuai Zhang, Zhoufei Yu, Xun Gong, Yue Wang, Fengming Chang, Gerrit Lohmann, Yiquan Qi, Tiegang Li"},"pubYear":2021,"title":"Precession cycles of the El Niņo/Southern oscillation-like system controlled by Pacific upper-ocean stratification","journal":"Communications Earth and Environment","volume":"2","edition":null,"issue":null,"pages":null,"reportNumber":"239","citation":"Shuai Zhang, Zhoufei Yu, Xun Gong, Yue Wang, Fengming Chang, Gerrit Lohmann, Yiquan Qi, Tiegang Li. 2021.

Moreover, studies have showed that such controls may operate on orbital cycles, although the details remain unclear. Here we present paired temperature and salinity reconstructions for the surface and thermocline waters in the central western Pacific warm pool over the past 360,000 years, as well as transit modeling results from an Earth system model. Our results show that variations in subsurface temperature and salinity in the western Pacific warm pool have consistently correlated with the shallow meridional overturning cell over the past four glacial-interglacial cycles, and they vary on eccentricity and precession cycles. The shallow meridional overturning cell regulates subsurface waters of the western Pacific warm pool by changing subtropical surface water density and thus equatorial upper-ocean stratification, acting as an El Niņo/Southern Oscillation-like process in the precession band. Therefore, the western Pacific warm pool is critical in connecting the austral shallow meridional overturning cell to the Earth's climate system on orbital timescales.","pubRank":"1"}],"site":[{"NOAASiteId":"59168","siteName":"KX97322-4","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>Western Pacific
