Research Abstract |
Corals are rich archives of climatic changes in tropical seas covering from the recent to distant past. The isotope and elemental compositions of coral skeletons reflect physicochemical parameters of the ambient seawater. In this study, we examine the magnitude of growth-rate influence on coral oxygen and carbon isotope and Sr/Ca ratios in a long-term common-garden culture experiment of Porites australiensis corals. This project involved paleoclimate analyses of coral skeletal records. Coral proxy records from Ogasawara and Ishigaki revealed several coupled phenomena during the early 20th century in the northwestern subtropical Pacific.
