| Outline of Final Research Achievements |
In this study, we measured cellulose δ18O of ten teak samples collected from four sites in Java Island, in order to evaluate the synchrony of Javanese teak δ18O and the potential as a climate proxy. As a result, teak δ18O time series had a significant correlation, suggesting that teak δ18O had a common climatic information in Java Island. Furthermore, we attempted to specify the environmental factors that determine the cellulose δ18O of teak tree-ring, based on correlation analyses with meteorological data and cellulose oxygen isotopic ratio model (proxy system model) analyses.
