Geology, January 2008, Vol. 36, pp. 11-14. doi:10.1130/G24321A.1 # Abstract: It is highly debated whether global warming contributed to the strong hurricane activity observed during the last decade. The crux of the recent debate is the limited length of the reliable instrumental record that exacerbates the detection of possible long-term changes in hurricane activity, which naturally exhibits strong multidecadal variations that are associated with the Atlantic Multidecadal Oscillation (AMO). The AMO, itself a major mode of climate variability, remains also poorly understood because of limited data. Here, we present the first coral-based proxy record (d18O) that clearly captures multidecadal variations in the AMO and the hurricane activity. Our record, obtained from a brain coral situated in the Atlantic hurricane domain, is equally sensitive to variations in sea surface temperature (SST) and seawater d18O, with the latter being strongly linked to precipitation, by this means amplifying large-scale climate signals in coral d18O. The SST and precipitation signals in the coral provide the longest, thus far, continuous proxy-based record of hurricane activity that interestingly exhibits a long-term increase over the last century. As multidecadal SST variations in this region are closely related to the AMO, this study raises new possibilities to extend the limited observations and to gain new insights into the mechanisms underlying the AMO and long-term hurricane variations. #------------------ # Funding_Agency # Funding_Agency_Name: Deutsche Forschungsgemeinschaft # Grant: Sonderforschungsbereich 460-B1, Du129/33 #------------------ # Funding_Agency # Funding_Agency_Name: DYNAMITE # Grant: GOCE 00393 #------------------ # Site_Information # Site_Name: Cayo Sal, Los Roques Archipelago, Venezuela # Location: South America>Venezuela # Country: Venezuela # Northernmost_Latitude: 11.77 # Southernmost_Latitude: 11.77 # Easternmost_Longitude: -66.75 # Westernmost_Longitude: -66.75 # Elevation: -2 m #------------------ # Data_Collection # Collection_Name: 08vene01b # Earliest_Year: 1918 # Most_Recent_Year: 2004 # Time_Unit: AD # Core_Length: # Notes: #------------------ # Species # Species_Name: Diploria strigosa # Common_Name: #------------------ # Chronology_Information # Chronology: # #---------------- # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ##age age, , ,years AD, , , , ,N ##d18O delta 18O, Diploria strigosa, , permil VPDB, , Corals and Sclerosponges, , annually averaged,N ##d18O_seas delta 18O, Diploria strigosa, , permil VPDB, August-October, Corals and Sclerosponges, , annually averaged,N ##d18O_anom delta 18O, Diploria strigosa, , permil VPDB, , Corals and Sclerosponges, normalized; annually averaged,N # #---------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Values: NAN # age d18O d18O_seas d18O_anom 1918 -3.726 -3.851 0.265 1919 -3.852 -3.982 0.175 1920 -3.632 -3.726 0.335 1921 -3.883 -4.168 0.077 1922 -3.999 -4.200 -0.034 1923 -3.871 -4.039 0.089 1924 -4.029 -4.281 -0.008 1925 -3.955 -4.134 0.032 1926 -3.990 -4.240 0.089 1927 -4.041 -4.251 0.033 1928 -3.894 -4.102 0.125 1929 -3.834 -3.969 0.129 1930 -3.825 -3.938 0.178 1931 -4.031 -4.152 0.114 1932 -4.149 -4.383 -0.040 1933 -4.210 -4.382 -0.146 1934 -4.049 -4.147 -0.033 1935 -4.170 -4.326 -0.130 1936 -4.145 -4.326 -0.040 1937 -4.067 -4.421 0.057 1938 -4.007 -4.178 0.085 1939 -3.904 -4.096 0.143 1940 -4.044 -4.209 0.059 1941 -4.179 -4.298 -0.040 1942 -4.109 -4.177 0.002 1943 -4.159 -4.317 -0.129 1944 -4.099 -4.209 0.007 1945 -4.227 -4.415 -0.124 1946 -4.166 -4.353 -0.102 1947 -4.058 -4.272 -0.033 1948 -4.171 -4.366 -0.107 1949 -3.950 -4.127 0.104 1950 -4.217 -4.429 -0.188 1951 -4.076 -4.149 0.068 1952 -4.106 -4.329 0.053 1953 -4.056 -4.184 0.057 1954 -4.196 -4.347 -0.122 1955 -4.345 -4.569 -0.269 1956 -4.087 -4.199 -0.026 1957 -3.914 -4.064 0.116 1958 -4.100 -4.277 0.103 1959 -4.041 -4.210 0.023 1960 -4.104 -4.148 0.075 1961 -4.015 -4.223 0.092 1962 -4.088 -4.317 0.044 1963 -4.100 -4.243 0.037 1964 -4.178 -4.427 -0.105 1965 -4.076 -4.299 -0.045 1966 -4.121 -4.268 -0.015 1967 -4.011 -4.153 0.063 1968 -4.121 -4.230 -0.031 1969 -4.168 -4.231 0.039 1970 -4.109 -4.228 0.029 1971 -3.960 -4.072 0.042 1972 -4.064 -4.319 -0.004 1973 -3.922 -4.088 0.161 1974 -3.888 -4.010 0.095 1975 -3.935 -4.242 0.075 1976 -4.014 -4.200 0.003 1977 -3.946 -4.166 0.138 1978 -3.949 -3.978 0.132 1979 -4.189 -4.394 -0.105 1980 -4.049 -4.202 0.063 1981 -4.210 -4.333 -0.052 1982 -4.022 -4.168 -0.003 1983 -4.086 -4.255 0.043 1984 -4.014 -4.122 -0.004 1985 -4.054 -4.193 -0.074 1986 -3.964 -4.189 0.018 1987 -4.123 -4.227 0.022 1988 -4.189 -4.361 -0.107 1989 -4.035 -4.192 -0.029 1990 -4.073 -4.243 -0.007 1991 -4.041 -4.133 -0.026 1992 -4.210 -4.321 -0.151 1993 -4.077 -4.243 -0.015 1994 -4.124 -4.405 -0.099 1995 -4.298 -4.546 -0.154 1996 -4.178 -4.331 -0.094 1997 -4.093 -4.124 -0.026 1998 -4.297 -4.467 -0.121 1999 -4.149 -4.291 -0.006 2000 -4.144 -4.325 -0.083 2001 -4.203 -4.406 -0.100 2002 -4.249 -4.395 -0.165 2003 -4.311 -4.510 -0.183 2004 NAN -4.467 NAN
