Yet few studies have systematically examined the natural variability in sclerosponge skeletal d18O, growth, and Sr/Ca, and how that may influence the interpretation of sclerosponge proxy records.  Here, we analyzed short records in seven specimens of Acanthocheatetes wellsi (high-Mg calcite, 21 mol% Mg) from Palau, four A. wellsi (high-Mg calcite, 21 mol% Mg) from Saipan, and three Astroclera willeyana (aragonite) sclerosponges from Saipan, as well as one long record in an A. wellsi specimen from Palau spanning 1945-2001.5.  In Saipan, species-specific and mineralogical effects appear to have a negligible effect on sclerosponge d18O, facilitating the direct comparison of d18O records between species at a given location.  At both sites, A. wellsi d18O and growth rates were sensitive to environmental conditions, while Sr/Ca was not.  High-resolution d18O analyses confirmed this finding as both A. wellsi and A. willeyana deposited their skeleton following the trends in isotopic equilibrium with seawater, though with a 0.27 pdf mil offset in the case of A. willeyana.  In the high Mg-calcite species A. wellsi, Mg may be interfering with Sr incorporation into the skeleton.  On multi-decadal timescales, A. wellsi sclerosponge d18O in Palau tracked the Southern Oscillation Index variability post-1977, but not pre-1977, coincident with the switch in the Pacific Decadal Oscillation (PDO) ~1976.   This suggests that water mass circulation in the region is influenced by ENSO variability during positive PDO phases, but not during negative ones.","pubRank":"1"}],"site":[{"NOAASiteId":"60018","siteName":"Short Drop Off (PAU1), Palau","siteCode":null,"mappable":"Y","locationName":"Ocean>Pacific Ocean>Western Pacific Ocean","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["7.269781","134.547524"]},"properties":{"southernmostLatitude":"7.269781","northernmostLatitude":"7.269781","westernmostLongitude":"134.547524","easternmostLongitude":"134.547524","minElevationMeters":"-17","maxElevationMeters":"-17"}},"paleoData":[{"dataTableName":"PAU1","NOAADataTableId":"51072","earliestYear":1945,"mostRecentYear":2002,"timeUnit":"CE","earliestYearBP":5,"mostRecentYearBP":-52,"earliestYearCE":1945,"mostRecentYearCE":2002,"coreLengthMeters":0,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/coral/west_pacific/grottoli2010-pau1.txt","urlDescription":"NOAA Template File","linkText":"Coral Growth Rate, d18O, d14C, and Sr/Ca Data","variables":[{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"sampling metadata>sample identification","cvMaterial":null,"cvError":null,"cvUnit":null,"cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Character","cvShortName":"sample_name"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>year Common Era","cvSeasonality":null,"cvDetail":"interpolated","cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"interpol_age"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"age variable>age","cvMaterial":null,"cvError":null,"cvUnit":"time unit>age unit>year Common Era","cvSeasonality":null,"cvDetail":"raw","cvMethod":null,"cvAdditionalInfo":"based on chronology established with d14C (per mil); see Chronology tab for d14C data","cvFormat":"Numeric","cvShortName":"age"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>isotope>isotope ratio>delta 18O","cvMaterial":"biological material>organism>sponge>sclerosponge>Acanthocheatetes sp.>Acanthocheatetes wellsi","cvError":null,"cvUnit":"concentration unit>parts per notation unit>parts per thousand>per mil>per mil VPDB","cvSeasonality":null,"cvDetail":"raw","cvMethod":"laboratory method>spectroscopy>mass spectrometry>isotope ratio mass spectrometry","cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"d18OPDB"},{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"depth variable>depth","cvMaterial":null,"cvError":null,"cvUnit":"length unit>centimeter","cvSeasonality":null,"cvDetail":null,"cvMethod":null,"cvAdditionalInfo":null,"cvFormat":"Numeric","cvShortName":"depth"}],"NOAAKeywords":["earth science>paleoclimate>corals and sclerosponges>oxygen isotopes","earth science>paleoclimate>corals and sclerosponges>trace metals"]}]}]}],"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}
