Stable isotope time series (46 samples) of delta18O and delta13C were measured in successive growth layers of the large Astrosclera from Ribbon Reef #10 (GBR). Astrosclera forms its skeletal aragonite in equilibrium with the ambient seawater, and represents, therefore, a high precision recorder of the isotopic history of the ambient seawater. Delta13C of surface water dissolved inorganic carbon in the northern Great Barrier Reef has apparently decreased continuously since the mid-16th century. The total decrease is 0.7 per mill. The major decline of 0.5 per mill. occurred during the industrial period of the 19th and 20th century, likely to be due to the increased release of CO2 by deforestation and burning of fossil fuel during the period of industrialization after 1850 (increased input of lighter carbon isotopes). The oxygen isotope history shows a slightly colder (and/or dryer) phase before 1850, which correlates with the Little Ice Age. A considerable shift to lighter values occurred during the 20th century (warming of SST). This may be due to an anthropogenic greenhouse effect. Most of the major climatic changes caused by ENSO/El Niño events as well as by large volcanic eruptions in the last four and a half centuries were recorded in the oxygen isotope record of Astrosclera. #-------------------- # Publication # Authors: Wörheide, G # Journal_Name: Facies # Published_Title: The reef cave dwelling ultraconservative coralline demosponge Astrosclera willeyana Lister 1900 from the Indo-Pacific # Published_Date_or_Year: 1998 # Volume: 38 # Issue: # Pages: 1-88 # Report_Number: # DOI: 10.1007/BF02537358 # Full_Citation: # Abstract: None #-------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #-------------------- # Site_Information # Site_Name: Ribbon Reef #10 # Location: Australia # Northernmost_Latitude: -14.67 # Southernmost_Latitude: -14.67 # Easternmost_Longitude: 145.67 # Westernmost_Longitude: 145.67 # Elevation_m: -23 #-------------------- # Data_Collection # Collection_Name: Ribbon Reef #10 Core 001 # First_Year: 1552 # Last_Year: 1990 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: del18O, SST, del13C # 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) # ## Number sample identification,,,dimensionless,,corals and sclerosponges,,,N, ## depth_mm depth,,,millimeter,,climate reconstructions;corals and sclerosponges,,,N, ## d13C delta 13C,Astrosclera willeyana,,per mil PDB,,corals and sclerosponges,raw,isotope ratio mass spectrometry,N, ## d18O delta 18O,Astrosclera willeyana,,per mil PDB,,corals and sclerosponges,raw,isotope ratio mass spectrometry,N, ## Temp temperature,delta 18O,,degree Celsius,,climate reconstructions;corals and sclerosponges,,,N,ocean temperature ## age_CE age,,,year Common Era,,climate reconstructions;corals and sclerosponges,,,N, #-------------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: Number depth_mm d13C d18O Temp age_CE 1 156.5 4.71 -0.81 24.2 1552 2 146.4 4.68 -0.86 24.43 1581 3 138.1 4.74 -0.79 24.1 1604 4 133.3 4.66 -0.87 24.47 1618 5 128.4 4.58 -1.08 25.45 1631 5 128.5 4.65 -1.04 25.27 1631 6 123.6 4.57 -0.94 24.8 1645 7 121.4 4.65 -0.85 24.38 1651 8 117.6 4.54 -0.91 24.66 1662 9 113.8 4.62 -0.93 24.75 1672 10 110.8 4.59 -0.85 24.38 1681 11 107.3 4.62 -0.92 24.71 1691 12 104.1 4.57 -0.97 24.94 1700 13 100.4 4.59 -0.89 24.57 1710 14 96.9 4.62 -0.91 24.66 1720 15 93.6 4.52 -0.88 24.52 1729 16 90.7 4.55 -0.86 24.43 1738 17 87.1 4.58 -0.89 24.57 1748 18 84.1 4.52 -0.92 24.71 1756 19 80.7 4.57 -0.87 24.47 1766 20 77.7 4.54 -0.94 24.8 1774 21 73.3 4.54 -0.96 24.89 1787 22 69.9 4.53 -0.9 24.61 1796 23 66.4 4.57 -0.81 24.2 1806 23 66.5 4.58 -0.84 24.34 1806 24 63.4 4.55 -0.92 24.71 1814 25 59.1 4.51 -0.89 24.57 1827 26 55.6 4.52 -0.96 24.89 1836 27 52.7 4.54 -0.84 24.34 1845 27 52.8 4.52 -0.86 24.43 1844 28 51.1 4.49 -1.05 25.31 1849 28 51.2 4.52 -1.02 25.17 1849 29 46.8 4.52 -0.95 24.85 1861 30 44.6 4.52 -0.86 24.43 1867 30 44.7 4.52 -0.78 24.06 1867 31 40.9 4.48 -1.06 25.36 1878 32 38.5 4.44 -1.01 25.13 1885 33 36 4.4 -0.99 25.03 1892 34 32.5 4.34 -0.97 24.94 1901 35 28.9 4.28 -0.92 24.71 1912 36 25.7 4.26 -0.87 24.47 1921 37 22.2 4.3 -0.92 24.71 1930 38 18.5 4.28 -0.9 24.61 1941 39 15.2 4.15 -0.95 24.85 1950 40 11.9 4.15 -1.03 25.22 1959 41 9.8 4.1 -1.16 25.83 1965 42 8.3 4.13 -1.08 25.45 1970 43 6.6 4.02 -1.1 25.55 1974 44 4.4 4.05 -1.01 25.13 1981 45 2.6 4.03 -0.95 24.85 1986 46 1 4.06 -0.93 24.75 1990
