We show that marine heat waves affecting the SEIO are linked to the behaviour of the Western Pacific Warm Pool on decadal to centennial timescales, and are most pronounced when an anomalously strong zonal SST gradient between the western and central Pacific co-occurs with strong La Niņa's. This SST gradient forces large-scale changes in heat flux that exacerbate SEIO heatwaves. Better understanding of the zonal SST gradient in the western Pacific is expected to improve projections of the frequency of extreme SEIO heatwaves and their ecological impacts on the important coral reef ecosystems off Western Australia. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: The University of Western Australia, UWA AGFIOR lab # Grant: UWA, AIMS, CSIRO IMROC fellowship #--------------------------------------- # Site Information # Site_Name: Rowley Shoals # Location: Rowley Shoals # Country: Australia # Northernmost_Latitude: -17.1 # Southernmost_Latitude: -17.5369 # Easternmost_Longitude: 119.6 # Westernmost_Longitude: 118.969 # Elevation: #--------------------------------------- # Data_Collection # Collection_Name: Rowley SST Zinke15 # First_Year: 1798 # Last_Year: 2009 # Time_Unit: AD # Core_Length: # Notes: annual sampling #--------------------------------------- # Species # Species_Name: Porites sp. # Common_Name: Porites #--------------------------------------- # Chronology: # mean annual #--------------------------------------- # Variables # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) ## age_AD age,,,years AD,,,,,N ## ssta-SrCa-por61-90 temperature anomaly,sea surface,,degrees Celsius,annual,,reference period: 1961-1990,reconstruction predictor: Sr/Ca coral,N #------------------------------ # Data # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Value: NA age_AD ssta-SrCa-por61-90 1798 -0.67026 1799 -0.93059 1800 -1.17219 1801 -0.80694 1802 -0.65899 1803 -0.36568 1804 -1.1018 1805 -0.43462 1806 -0.27155 1807 -0.49126 1808 -0.07316 1809 -0.24982 1810 -0.58542 1811 -0.52864 1812 -1.03347 1813 -0.53092 1814 -0.36591 1815 -0.25829 1816 -0.48714 1817 -1.35586 1818 -1.04852 1819 -0.74648 1820 -0.5581 1821 -0.27568 1822 -0.27251 1823 -0.44711 1824 -0.01861 1825 -0.27506 1826 -0.05338 1827 -0.44408 1828 -0.34072 1829 -0.04603 1830 -0.3371 1831 -0.31394 1832 0.220435 1833 -0.74225 1834 -0.53511 1835 -0.62662 1836 -1.10365 1837 -1.11472 1838 -1.211 1839 -0.4243 1840 -0.8195 1841 -0.83197 1842 -0.87066 1843 -0.52537 1844 -0.46771 1845 -0.3602 1846 -0.46447 1847 -0.35058 1848 -0.33315 1849 -0.66009 1850 -0.65435 1851 -1.08455 1852 -1.11346 1853 -1.13831 1854 -1.85924 1855 -0.87568 1856 -1.07376 1857 -1.14211 1858 -0.99569 1859 -0.69109 1860 -0.31296 1861 -0.33659 1862 -0.52482 1863 -0.41123 1864 -0.6436 1865 -0.8667 1866 -0.932 1867 -0.76005 1868 -0.25511 1869 0.374138 1870 -0.06007 1871 -0.62779 1872 -0.79137 1873 -0.54245 1874 -0.66032 1875 -0.80715 1876 -1.26834 1877 -0.65698 1878 -0.20771 1879 0.230667 1880 -0.30548 1881 -0.81188 1882 -0.60949 1883 -0.66754 1884 -0.77936 1885 -0.93207 1886 -0.71453 1887 -0.34349 1888 0.095072 1889 0.489568 1890 -0.81779 1891 -0.77357 1892 -0.5007 1893 -0.22162 1894 -0.53004 1895 -0.84666 1896 -0.67353 1897 -0.09809 1898 -0.06717 1899 -0.23627 1900 -0.23273 1901 -0.17948 1902 -0.20792 1903 -0.1294 1904 -0.57804 1905 -0.40816 1906 -0.26548 1907 -0.2634 1908 -0.60174 1909 0.134051 1910 -0.12817 1911 -0.2448 1912 -0.05351 1913 -0.79898 1914 -0.36999 1915 -0.54868 1916 -0.00222 1917 -0.50249 1918 -0.10069 1919 -0.17304 1920 -0.13043 1921 -0.34052 1922 -0.14887 1923 -0.29679 1924 -0.28662 1925 -0.55589 1926 -0.36094 1927 -0.25619 1928 -0.10069 1929 -0.17367 1930 -0.0195 1931 0.173497 1932 0.059727 1933 0.405496 1934 -0.1046 1935 -0.26826 1936 0.046358 1937 0.018896 1938 0.107532 1939 -0.1554 1940 -0.24788 1941 -0.05362 1942 -0.15296 1943 -0.04325 1944 0.114105 1945 0.201286 1946 0.231211 1947 0.304382 1948 0.239164 1949 0.089267 1950 0.195195 1951 -0.36044 1952 -0.58722 1953 0.126021 1954 0.357769 1955 0.406533 1956 0.128106 1957 -0.03487 1958 0.094385 1959 -0.03927 1960 -0.31102 1961 -0.31967 1962 -0.13026 1963 -0.15612 1964 -0.02688 1965 0.05698 1966 -0.03712 1967 0.064133 1968 -0.15201 1969 0.071491 1970 -0.10094 1971 0.213553 1972 -0.17288 1973 -0.00484 1974 0.192189 1975 0.27841 1976 -0.02443 1977 -0.28986 1978 -0.23141 1979 -0.17616 1980 -0.09211 1981 -0.01606 1982 -0.00912 1983 -0.32911 1984 -0.01099 1985 -0.02221 1986 0.066258 1987 0.209919 1988 0.32711 1989 0.369976 1990 0.453866 1991 0.413838 1992 0.154628 1993 0.088679 1994 0.229235 1995 0.392778 1996 0.461382 1997 0.459905 1998 0.541168 1999 1.030348 2000 0.597309 2001 0.42775 2002 0.385208 2003 0.300973 2004 0.084268 2005 0.168601 2006 0.082018 2007 0.294216 2008 0.512818 2009 0.802216
