This results in highly variable river flows affecting nearshore coral reefs of the Great Barrier Reef, Australia. Freshwater flood events are recorded in long-lived, annually banded massive coral skeletons as luminescent lines. Quantitative measurements of luminescence intensity were made for 20 Porites coral cores from nearshore reef sites between 11°S and 23°S. Seventeen of the coral luminescence series were significantly correlated with an instrumental record of northeast Queensland summer rainfall and were used to develop seven significantly calibrated and verified rainfall reconstructions based on between 17 (starting 1891) and 1 (starting 1639) coral series. The longest reconstruction, based on more than one coral, provides insights into northeast Queensland rainfall variability from the late 17th century. Comparisons with various independent climate proxies are equivocal: the magnitude and significance of relationships with, for example, a proxy ENSO index vary through time. An extended drier period reconstructed from approximately the 1760s to the 1850s is associated with lower interannual rainfall variability. Since the late 19th century average rainfall and its variability have significantly increased, with wet and dry extremes becoming more frequent than in earlier centuries. This suggests that a warming global climate maybe associated with more variable tropical Queensland rainfall. #-------------------- # Funding_Agency #-------------------- # Site_Information # Site_Name: Havannah # Location: Ocean>Pacific Ocean # Region: PAGES Australasia 2k # Country: Australia # Northernmost_Latitude: -18 # Southernmost_Latitude: -18 # Easternmost_Longitude: 147 # Westernmost_Longitude: 147 # Elevation: #-------------------- # Data_Collection # Collection_Name: R17 Coral Luminescence for PAGES Australasia 2k regional reconstructions # Earliest_Year: 1891 # Most_Recent_Year: 1981 # Time_Unit: AD # Notes: Calibrated rainfall reconstruction #-------------------- # Species #-------------------- # Chronology: #-------------------- # Variables # Short_name What,Material,Error,Units, Anomaly_period,Archive,Details,Method,Data_type ## age_AD age, , ,AD, ,corals, ,,N ## GBR_RR_recon_R17 Coral Luminescence rainfall reconstruction,coral,,mm,,coral,,,N #-------------------- # Data # Missing values: NA age_AD GBR_RR_recon_R17 1891 1308.4 1892 731.3 1893 1161.7 1894 1209.4 1895 1233.6 1896 1645.2 1897 733.4 1898 1413.1 1899 1099.0 1900 868.8 1901 1193.1 1902 881.4 1903 1262.4 1904 951.1 1905 1053.1 1906 1321.7 1907 869.2 1908 1080.2 1909 821.2 1910 1542.5 1911 1384.5 1912 873.4 1913 1134.4 1914 970.8 1915 749.5 1916 909.1 1917 1155.4 1918 1631.0 1919 977.8 1920 880.3 1921 892.6 1922 1005.8 1923 809.7 1924 1068.1 1925 1054.0 1926 778.4 1927 1287.1 1928 1125.4 1929 930.0 1930 1098.9 1931 755.5 1932 902.1 1933 828.3 1934 1146.2 1935 866.6 1936 1273.1 1937 1010.1 1938 906.9 1939 909.2 1940 1366.2 1941 1104.7 1942 875.1 1943 1130.0 1944 1045.0 1945 955.2 1946 1048.3 1947 1001.6 1948 810.6 1949 1188.9 1950 1380.2 1951 985.0 1952 835.7 1953 1162.1 1954 1357.6 1955 1443.6 1956 1185.2 1957 1003.8 1958 1353.7 1959 1016.6 1960 941.7 1961 722.6 1962 912.5 1963 1098.2 1964 726.4 1965 840.4 1966 739.0 1967 971.6 1968 1368.6 1969 768.9 1970 1110.0 1971 1537.2 1972 1262.1 1973 995.5 1974 1991.8 1975 1092.4 1976 1292.7 1977 1125.6 1978 823.7 1979 1429.3 1980 806.1 1981 1295.5
