These proxy records of environmental change are preserved as geochemical signals in the carbonate skeletons of scleractinian corals and are useful for reconstructions of temporal and spatial fluctuations in the physical and chemical environments of coral reef ecosystems, including The Great Barrier Reef (GBR). We compared multi-year monitoring of water temperature and dissolved elements with analyses of chemical proxies recorded in Porites coral skeletons to identify the divergent mechanisms driving environmental variation at inshore versus offshore reefs. At inshore reefs, water Ba/Ca increased with the onset of monsoonal rains each year, indicating a dominant control of flooding on inshore ambient chemistry. Inshore multi-decadal records of coral Ba/Ca were also highly periodic in response to flood-driven pulses of terrigenous material. In contrast, an offshore reef at the edge of the continental shelf was subject to annual upwelling of waters that were presumed to be richer in Ba during summer months. Regular pulses of deep cold water were delivered to the reef as indicated by in situ temperature loggers and coral Ba/Ca. Our results indicate that although much of the GBR is subject to periodic environmental fluctuations, the mechanisms driving variation depend on proximity to the coast. Inshore reefs are primarily influenced by variable freshwater delivery and terrigenous erosion of catchments, while offshore reefs are dominated by seasonal and inter-annual variations in oceanographic conditions that influence the propensity for upwelling. The careful choice of sites can help distinguish between the various factors that promote Ba uptake in corals and therefore increase the utility of corals as monitors of spatial and temporal variation in environmental conditions.","pubRank":"1"}],"site":[{"NOAASiteId":"61710","siteName":"Havannah Island East","siteCode":null,"mappable":"Y","locationName":"Continent>Australia/New Zealand>Australia","geo":{"geoType":"Feature","geometry":{"type":"POINT","coordinates":["-18.8396","146.5502"]},"properties":{"southernmostLatitude":"-18.8396","northernmostLatitude":"-18.8396","westernmostLongitude":"146.5502","easternmostLongitude":"146.5502","minElevationMeters":"-3","maxElevationMeters":"-3"}},"paleoData":[{"dataTableName":"Havannah Ba/Ca Walther2013","NOAADataTableId":"51808","earliestYear":1962,"mostRecentYear":2008,"timeUnit":"CE","earliestYearBP":-12,"mostRecentYearBP":-58,"earliestYearCE":1962,"mostRecentYearCE":2008,"coreLengthMeters":0,"dataTableNotes":"Porites sp.","species":[],"dataFile":[{"fileUrl":"https://www.ncei.noaa.gov/pub/data/paleo/coral/west_pacific/great_barrier/walther2013/walther2013-hav-baca.txt","urlDescription":"NOAA Template File","linkText":"Havannah Ba/Ca 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>element or compound ratio>barium/calcium","cvMaterial":"biological material>organism>coral>Porites sp.","cvError":null,"cvUnit":"concentration unit>mole fraction unit>micromole per mole","cvSeasonality":null,"cvDetail":"interpolated","cvMethod":"laboratory method>spectroscopy>mass spectrometry>inductively-coupled plasma mass spectrometry","cvAdditionalInfo":"Smoothed with a 10-point averaging box and time series interpolated to monthly resolution.
