The PDO has widespread climatic and societal impacts, thus understanding the processes contributing to PDO variability is critical. Distinguishing PDO-related variability is particularly challenging in the tropical Pacific due to the dominance of the El Niņo-Southern Oscillation (ENSO) and influence of anthropogenic warming signals. Century-long western Pacific records of sub-annual sea surface temperature (SST) and sea surface salinity (SSS), derived from coral Sr/Ca and d18O profiles, respectively, allow for evaluating different climatic sensitivities and identifying PDO-related variability in the region. The summer Sr/Ca-SST record provides evidence of a significant SST increase, likely tied to greenhouse gas emissions. Anthropogenic warming is masked in the winter Sr/Ca-SST record by interannual to multidecadal scale changes driven by the East-Asian Winter Monsoon and the PDO. Decadal climate variability during winter is strongly correlated to the PDO, in agreement with other PDO records in the region. The PDO also exerts influence on the SSS difference between the dry and wet season coral d18O (d18Oc)-SSS records through water advection. The PDO and ENSO constructively combine to enhance/reduce advection of saline Kuroshio waters at our site. Overall, we are able to demonstrate that climate records from a tropical reef environment significantly capture PDO variability and related changes over the period of a century. This implies that the tropical western Pacific is a key site in understanding multifrequency climate variability, including its impact on tropical climate at longer timescales.","pubRank":"1"}],"site":[{"NOAASiteId":"57204","siteName":"Palaui Island","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>Western Pacific Ocean>Philippines","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["18.54","122.15"]},"properties":{"southernmostLatitude":"18.54","northernmostLatitude":"18.54","westernmostLongitude":"122.15","easternmostLongitude":"122.15","minElevationMeters":"-5","maxElevationMeters":"-5"}},"paleoData":[{"dataTableName":"Palaui PL d18O and Sr/Ca Ramos2019","NOAADataTableId":"39735","earliestYear":1880,"mostRecentYear":2012,"timeUnit":"CE","earliestYearBP":70,"mostRecentYearBP":-62,"earliestYearCE":1880,"mostRecentYearCE":2012,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/coral/west_pacific/ramos2019/ramos2019-month-noaa.txt","urlDescription":"NOAA Template File","linkText":"Palaui Island Monthly Sr/Ca and d18O Data","variables":[{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>year Common Era","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":"monthly","cvFormat":"Numeric","cvShortName":"age_CE"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>element or compound ratio>strontium/calcium","cvMaterial":"biological material>organism>coral>Porites sp.>Porites lobata","cvError":null,"cvUnit":"concentration unit>mole fraction unit>millimole per mole","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>electronic spectroscopy>atomic spectroscopy>inductively-coupled plasma atomic emission spectroscopy","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"Sr/Ca-P.loba"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>coral>Porites sp.>Porites lobata","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil VPDB","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d18O-P.loba"}],"NOAAKeywords":["earth science>paleoclimate>corals and sclerosponges>trace metals","earth science>paleoclimate>corals and sclerosponges>oxygen isotopes"]}]},{"dataTableName":"Palaui PL d18O seasonal Ramos2019","NOAADataTableId":"39736","earliestYear":1880,"mostRecentYear":1893,"timeUnit":"CE","earliestYearBP":70,"mostRecentYearBP":57,"earliestYearCE":1880,"mostRecentYearCE":1893,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/coral/west_pacific/ramos2019/ramos2019-season-noaa.txt","urlDescription":"NOAA Template File","linkText":"Palaui Island Seasonal d18O Data","variables":[{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>year Common Era","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"age_CE"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>coral>Porites sp.>Porites lobata","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil VPDB","cvSeasonality":"4-month period>Dec-Mar","cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d18O-P.loba-dry"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>coral>Porites sp.>Porites lobata","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil VPDB","cvSeasonality":"4-month period>Jun-Sep","cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d18O-P.loba-wet"}],"NOAAKeywords":["earth science>paleoclimate>corals and sclerosponges>oxygen isotopes"]}]}]}],"reference":{"pastThesaurusSkos":"https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf","pastThesaurusExplorer":"https://www.ncei.noaa.gov/access/paleo-search/cvterms","gcmdKeywordThesaurus":"https://earthdata.nasa.gov/earth-observation-data/find-data/idn/gcmd-keywords"},"dataLicenseDescription":null,"dataLicenseUrl":null}
