Summary:Records of skeletal d18O in monthly and Sr/Ca ratios in half-yearly resolution were obtained from a Bermuda coral (Diploria labyrinthiformis) for the time period 1520-1603 (±15 years) A.D. within the Little Ice Age. Annual and decadal averages of both sea surface temperature proxies indicate temperature variabilities of 0.5 °C (standard deviation) and 0.3 °C, respectively. Both numbers are close to recent instrumental observations. Approximately 30% of the interannual time series variance of d18O is concentrated in broad bands centered at periods of ~30, 16, and 7.8 years, the last two reflecting the influence of the North Atlantic Oscillation. Although this large-scale climate signal is present in the record, there is no correlation with other contemporaneous Northern Hemisphere proxy data, resulting from spatial differences in climate variability.More Info on Corals and Sclerosponges |
