Coral δ18O faithfully records interannual variability even when strongly influenced by kinetic effects. Interannual to decadal variability of coral δ13 remains enigmatic; only one of the two corals exhibits the expected light-δ13C response in the interannual band. Coral δ18O from this region has a great similarity to global instrumental temperature records reflecting the impact of the Pacific warm pool and variations of the Indonesian Low in concert with El Niño-Southern Oscillation on global climate. Since 1896, coral δ18O has exhibited a cumulative decrease of 0.7‰, which reflects a combination of warming and more frequent El Niño events (precipitation) affecting the surface waters of this region.","author":{"name":"Guilderson, T.P.; Schrag, D.P"},"citation":"Guilderson, T.P.; Schrag, D.P. 1999.
