DENDROCHRONOLOGIA Vol. 52 page： 80 - 86 2018.12

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：ELSEVIER GMBH, URBAN & FISCHER VERLAG

The oxygen isotopic composition (delta O-18) of tree-ring cellulose has been recognized as a powerful tool for dendroclimatological and dendrochronological investigations in Asia. Only a few studies of cellulose delta O-18 so far published, however, have been conducted in Indonesia, and the spatial coherence of cellulose delta O-18 has yet to be clarified. In this study we measured cellulose delta O-18 of teak (Tectona grandis) collected from four sites on Java Island to evaluate the similarity between the different teak delta O-18 values and the potential for using teak delta O-18 both as a climate proxy and as a tool for cross-dating. Cellulose delta O-18 time series of Javanese teaks were found to be significantly correlated in all of the comparisons between sites, even between sites separated by a distance as great as 400 km. While significant correlations did not appear in the ring width data between our samples (expressed population signal (EPS) = 0.64; Rbar = 0.23; sample depth = 10), they were found between the cellulose delta O-18 values (EPS = 0.89; Rbar = 0.58; sample depth = 10). These results suggest that teak delta O-18 variations have higher spatial coherence and might be a useful tool for cross-dating. A significant negative correlation was observed between cellulose delta O-18 and the relative humidity/precipitation during the rainy season, indicating that the cellulose delta O-18 of Javanese teak is an effective proxy for relative humidity/precipitation during the rainy season. Cellulose delta O-18 was found to be positively correlated with precipitation during the dry season preceding the growing season, whereas it showed no correlations with the temperature and Palmer Drought Severity Index (PDSI), the key constraints of delta O-18 on the Indochina Peninsula.
