An acceleration of the overturning circulation can act to reduce global surface temperature as ocean stores more heat. The equatorward low-latitude western boundary current represents a key component of the meridional circulation cell in the Pacific and a major source of water mass for the Equatorial Undercurrent, yet long-term observations of its transport are scarce. Here we demonstrate that the 15N/14N ratio recorded by Porites spp. corals in the western tropical South Pacific is sensitive to the exchanges of water masses driven by the western boundary transport. Using a 94-year coral record from the Solomon Sea, we report that the 15N/14N ratio declined as the global surface temperature rose. The record suggests that the South Pacific western boundary current has strengthened in the past century, and it may have contributed to the reported strengthening of the Equatorial Undercurrent. In addition, the 15N/14N record shows strong decadal variability, indicative of weaker equatorial Pacific upwelling and stronger western boundary transport when the eastern equatorial Pacific is in the warm stage of the Pacific Decadal Oscillation.","pubRank":"1"}],"site":[{"NOAASiteId":"59833","siteName":"12NAK","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>South Pacific Ocean>Melanesia>Solomon Islands","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["-7.87","156.5"]},"properties":{"southernmostLatitude":"-7.87","northernmostLatitude":"-7.87","westernmostLongitude":"156.5","easternmostLongitude":"156.5","minElevationMeters":"-1","maxElevationMeters":"-1"}},"paleoData":[{"dataTableName":"12NAK-K","NOAADataTableId":"50339","earliestYear":1919,"mostRecentYear":2012,"timeUnit":"CE","earliestYearBP":31,"mostRecentYearBP":-62,"earliestYearCE":1919,"mostRecentYearCE":2012,"coreLengthMeters":2,"dataTableNotes":"Porites coral skeleton-bound nitrogen isotopes","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/coral/south_pacific/chen2023/chen-12nak-k.txt","urlDescription":"NOAA Template File","linkText":"Nitrogen, Oxygen and Carbon Isotope 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"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 15N","cvMaterial":"biological material>organism>coral>Porites sp.","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil AIR","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d15N"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 15N","cvMaterial":"biological material>organism>coral>Porites sp.","cvError":"standard deviation>one standard deviation","cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil AIR","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d15N_err"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 13C","cvMaterial":"biological material>organism>coral>Porites sp.","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d13C"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 13C","cvMaterial":"biological material>organism>coral>Porites sp.","cvError":"standard deviation>one standard deviation","cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d13C_err"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>coral>Porites sp.","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d18O"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>coral>Porites sp.","cvError":"standard deviation>one standard deviation","cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil PDB","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d18O_err"}],"NOAAKeywords":["earth science>paleoclimate>corals and sclerosponges>oxygen isotopes","earth science>paleoclimate>corals and sclerosponges>carbon 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}
