Although abundant, Isopora is largely absent from paleoceanographic literature. The scarcity of large Porites and the abundance of Isopora retrieved from the Great Barrier Reef (GBR) on Integrated Ocean Drilling Program Expedition 325 focused paleoceanographic attention on Isopora. Here we provide the first independent high-resolution calibration of both Sr/Ca and δ18O for temperature analyses based on Isopora and demonstrate its consistency with Porites records. We developed modern skeletal Sr/Ca- and δ18O-sea surface temperature (SST) calibrations based on five modern Isopora colonies from Heron Island in the southern GBR. Pairing the coral Sr/Ca record with monthly SST data yielded Sr/Ca-SST sensitivities from −0.061 ± 0.004 (centered) to −0.083 ± 0.007 (raw) mmol/mol °C−1 based on reduced major axis regressions. These sensitivities are in the middle of the range of published Porites values and overlap most published values for Isopora, −0.075 ± 0.011 to −0.065 ± 0.011 mmol/mol °C−1. The δ18O-SST sensitivities range from −0.184 ± 0.014 (centered) to −0.185 ± 0.014 (raw) ‰ °C−1, assuming that all seasonal variation in δ18O was due to SST. These δ18O-SST sensitivities are smaller than the widely accepted value of −0.23‰ °C−1 for biogenic aragonite but are at the upper end of high-resolution Porites-defined sensitivities that are consistently less than the aforementioned established value. Our results validate the use of Isopora as an alternative source of paleoceanographic records in habitats where large massive Porites are scarce or absent. #-------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: OCE-1356948 #-------------------- # Site_Information # Site_Name: Heron Island Reef # Location: Australia # Northernmost_Latitude: -23.45 # Southernmost_Latitude: -23.45 # Easternmost_Longitude: 151.92 # Westernmost_Longitude: 151.92 # Elevation_m: #-------------------- # Data_Collection # Collection_Name: Heron Island HER Brenner17 # First_Year: 2007 # Last_Year: 2012 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: trace metals, oxygen isotopes # Notes: #-------------------- # Chronology_Information # Chronology: # #-------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by '##' in columns one and two. # Variables list, one per line, shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## age_CE age,,,year Common Era,,corals and sclerosponges,,,N, ## d18O_HER12-13 delta 18O,Isopora sp.,,per mil PDB,,corals and sclerosponges,interpolated,isotope ratio mass spectrometry,N,12 pts per year interp; from core HER12-13 ## SrCa_HER12-13 strontium/calcium,Isopora sp.,,millimole per mole,,corals and sclerosponges,interpolated,inductively-coupled plasma atomic emission spectroscopy,N,12 pts per year interp; from core HER12-13 ## d18O_HER-OR delta 18O,Isopora sp.,,per mil PDB,,corals and sclerosponges,interpolated,isotope ratio mass spectrometry,N,12 pts per year interp; from core HER-OR ## SrCa_HER-OR strontium/calcium,Isopora sp.,,millimole per mole,,corals and sclerosponges,interpolated,inductively-coupled plasma atomic emission spectroscopy,N,12 pts per year interp; from core HER-OR #-------------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: NA age_CE d18O_HER12-13 SrCa_HER12-13 d18O_HER-OR SrCa_HER-OR 2012.333333 -4.17300003 9.19265328 -3.622 9.0881395 2012.25 -4.47933333 9.17405637 -4.33700002 8.95167001 2012.166667 -4.665 8.94070327 -4.388 8.860901 2012.083333 -4.48099999 9.1247405 -4.28354167 8.93819016 2012 -4.26800002 9.19702878 -4.13833334 9.10974187 2011.916667 -4.14900002 9.32303651 -4.03300001 9.22854123 2011.833333 -3.90100007 9.38255638 -3.89150005 9.3688063 2011.75 -3.74300005 9.45925461 -3.49691674 9.34018629 2011.666667 -3.60200002 9.51843484 -3.50999994 9.47720498 2011.583333 -3.6164999 9.32959852 -3.68092855 9.42623069 2011.5 -3.89199997 9.34138528 -3.79899991 9.32311948 2011.416667 -4.11174986 9.24848385 -4.0292857 9.33016107 2011.333333 -4.36599966 9.1934426 -3.91357154 9.34889406 2011.25 -4.32600009 9.15786332 -3.8195714 9.25735298 2011.166667 -4.67399954 9.09802917 -4.11471414 9.17239242 2011.083333 -4.54400038 9.04441058 -4.18428175 9.16675802 2011 -4.13100028 9.18754124 -3.98533356 9.36057766 2010.916667 -3.81800031 9.30839903 -4.08700015 9.32191436 2010.833333 -3.9279993 9.39522552 -4.17099979 9.303979 2010.75 -3.61200028 9.34448263 -4.09700022 9.36526037 2010.666667 -3.63200037 9.46618132 -4.06433326 9.38060472 2010.583333 NA 9.58851218 -4.08753848 9.41014292 2010.5 NA NA -4.06176925 9.20371917 2010.416667 NA NA -4.03600002 9.29896892 2010.333333 NA NA -4.06399998 9.27059403 2010.25 NA NA -4.16799983 9.265761 2010.166667 NA NA -4.25499992 9.0563702 2010.083333 NA NA -4.568 9.19088306 2010 NA NA -4.568 9.20796011 2009.916667 NA NA -4.4818001 9.22176285 2009.833333 NA NA -4.56746684 9.31815661 2009.75 NA NA -4.30946704 9.32867894 2009.666667 NA NA -4.10680014 9.34708098 2009.583333 NA NA -4.35579987 9.24522272 2009.5 NA NA -4.51113311 9.2249366 2009.416667 NA NA -4.68929985 9.25273652 2009.333333 NA NA -4.7947999 9.19476444 2009.25 NA NA -4.87879988 9.10870495 2009.166667 NA NA -4.95579989 8.9777492 2009.083333 NA NA -5.03830194 9.23872801 2009 NA NA -4.77429961 9.25112722 2008.916667 NA NA -4.80242496 9.19158641 2008.833333 NA NA -4.19980154 9.17700708 2008.75 NA NA -4.04030043 9.30207885 2008.666667 NA NA -4.08879965 9.41475779 2008.583333 NA NA -4.28979965 9.32709323 2008.5 NA NA -4.25440028 9.25322734 2008.416667 NA NA -4.05500054 9.28210134 2008.333333 NA NA -4.05449973 9.3811018 2008.25 NA NA -4.09750031 9.23781788 2008.166667 NA NA -4.12799976 9.27066797 2008.083334 NA NA -4.42350028 9.12473843 2008 NA NA -4.0170011 9.09918286 2007.916667 NA NA -4.30749964 9.18013595 2007.833334 NA NA -4.36799999 9.12318945 2007.75 NA NA -4.29750029 9.10509337 2007.666667 NA NA -4.1590003 9.41126707 2007.583334 NA NA -4.2054999 9.33132489 2007.5 NA NA -3.86700121 9.45625812
