However, any hydrologic interpretation of Ba/Cacor time-series requires thorough evaluation of regional climate, even at sites in close proximity to one another. Here we explore how two corals can be used to provide insight into hydroclimate in the Gulf of Chiriquí, Panama (GoC) using Ba/Cacor, a region whose climate is dictated by seasonal and lower frequency shifts in the Intertropical Convergence Zone. The main purpose of this study is to provide a preliminary assessment of Ba/Cacor replication in pursuit of a regional geochemical network. The two corals analyzed in this study (Secas Island, S1 and Coiba, IC4A-2) were collected ~74 km apart and grew in different reef settings at vastly different distances from the main river discharge points. Analytical uncertainty prevents complete confidence determining whether a small geochemical offset Ba/Cacor exists between our two records. However, temporal variability in S1 and IC4A-2 are well correlated at all examined temporal scales (rmonthly=0.70, rannual=0.65, rwet season=0.67, rdry season=0.55, rannual amplitude=0.77). Considering a potential geochemical offset may exist between the two corals, we took a conservative approach and examined S1 and IC4A-2 separately to establish a relationship with river discharge. Both corals, barring IC4A-2 dry season averages, are statistically significantly correlated to river discharge, permitting the creation of Reduced Major Axis regressions to quantify the relationship. Ultimately, in regions where river discharge dominates, a network of Ba/Cacor records may assist in reconstructing regional variability or notable deviations in hydroclimate. With additional and temporally longer Ba/Cacor records, we will be able to apply our framework to more clearly reconstruct river discharge variability throughout the GoC.","pubRank":"1"}],"site":[{"NOAASiteId":"1857","siteName":"Secas Island Coral S1","siteCode":null,"mappable":"Y","locationName":"Continent>North America>Central America>Panama","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["7.983","-82.05"]},"properties":{"southernmostLatitude":"7.983","northernmostLatitude":"7.983","westernmostLongitude":"-82.05","easternmostLongitude":"-82.05","minElevationMeters":"-3","maxElevationMeters":"-3"}},"paleoData":[{"dataTableName":"S1_Ba-Ca","NOAADataTableId":"51144","earliestYear":1918,"mostRecentYear":1984,"timeUnit":"CE","earliestYearBP":32,"mostRecentYearBP":-34,"earliestYearCE":1918,"mostRecentYearCE":1984,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleocean/pacific/brenner2023/brenner2023-s1_ba-ca.txt","urlDescription":"NOAA Template File","linkText":"Ba/Ca Data","variables":[{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>element or compound ratio>barium/calcium","cvMaterial":"biological material>organism>coral>Porites sp.>Porites lobata","cvError":null,"cvUnit":"concentration unit>mole fraction unit>micromole per mole","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>electronic spectroscopy>atomic spectroscopy>inductively-coupled plasma atomic emission spectroscopy","cvAdditionalInfo":"Ba/Ca geochemistry for S1","cvFormat":"Numeric","cvShortName":"Ba/Ca_S1"},{"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":"Year"}],"NOAAKeywords":["earth science>paleoclimate>corals and sclerosponges>trace metals"]}]}]},{"NOAASiteId":"60030","siteName":"Gulf of Chiriqui Coral IC4A-2","siteCode":null,"mappable":"Y","locationName":"Continent>North America>Central America>Panama","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["7.416667","-81.7"]},"properties":{"southernmostLatitude":"7.416667","northernmostLatitude":"7.416667","westernmostLongitude":"-81.7","easternmostLongitude":"-81.7","minElevationMeters":"-3","maxElevationMeters":"-3"}},"paleoData":[{"dataTableName":"IC4A-2_Ba-Ca","NOAADataTableId":"51143","earliestYear":1918,"mostRecentYear":1997,"timeUnit":"CE","earliestYearBP":32,"mostRecentYearBP":-47,"earliestYearCE":1918,"mostRecentYearCE":1997,"coreLengthMeters":null,"dataTableNotes":null,"species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/paleocean/pacific/brenner2023/brenner2023-ic4a-2_ba-ca.txt","urlDescription":"NOAA Template File","linkText":"Ba/Ca Data","variables":[{"cvDataType":"CORALS AND SCLEROSPONGES","cvWhat":"chemical composition>element or compound ratio>barium/calcium","cvMaterial":"biological material>organism>coral>Porites sp.>Porites lobata","cvError":null,"cvUnit":"concentration unit>mole fraction unit>micromole per mole","cvSeasonality":null,"cvDetail":null,"cvMethod":"laboratory method>spectroscopy>electronic spectroscopy>atomic spectroscopy>inductively-coupled plasma atomic emission spectroscopy","cvAdditionalInfo":"Ba/Ca geochemistry for IC4A-2","cvFormat":"Numeric","cvShortName":"Ba/Ca_IC4A2"},{"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":"Year"}],"NOAAKeywords":["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}
