| Abstract | Stable isotope analysis of two separate corals from Nauru Island in the warm pool of the western tropical Pacific confum that coral oxygen isotopes are a robust recorder of environmental variables.Coral 0180faithfully records interannual variability even when strongly influenced by kinetic effects. Interannual to decadal variability of coral oDe remains enigmatic; only one of the two corals exhibits the expected light-oDCresponse in the interannual band. Coral 0180from this region has a great similarityto global instrumental temperature records reflecting the impact of the Pacific warm pool and variations of the Indonesian Low in concert with EI Nino-Southern Oscillation on global climate. Since 1896,coral 0180has exhibiteda cumulativedecrease of 0.7%0,which reflects a combination of warming and more frequent EI Nino events (precipitation) affecting the surface waters of this region. |
