Development of Tree-Ring Chronologies from Indonesia and Thailand for Dendroclimatic Studies

D'Arrigo, Rosanne D.哥伦比亚大学标题：用于树木气候研究的印度尼西亚和泰国的树木年轮年表的发展该奖项支持继续努力开发一个空间综合的高分辨率网络，用于树木气候分析的精确年代的印度尼西亚和泰国的树木年轮年表。这些地区是研究季风和厄尔尼诺-南方涛动（ENSO）变率的关键。然而，东南亚是全球树木年轮和其他古气候数据来源数据最稀疏的地区之一。该战略将是（通过非破坏性手段）从印度尼西亚和泰国降雨季节性明显的地点收集选定热带树种的木材样本。这些样品将被严格地交叉测定年代，并发展成最终的年表。这些年表将用于近几个世纪东南亚气候的树木气候模拟和重建。

Abstract ATM-9705676 D'Arrigo, Rosanne D. Columbia University Title: Development of Tree-Ring Chronologies from Indonesia and Thailand for Dendroclimatic Studies This award supports the continuation of efforts to develop a spatially-comprehensive network of high-resolution, precisely-dated tree-ring chronologies from Indonesia and Thailand for dendroclimatic analysis. These regions are key to studies of monsoon and El Nino-Southern Oscillation (ENSO) variability. Yet, Southeast asia is one of the most data-sparse regions on the globe for coverage of tree-ring and other sources of paleoclimate data. The strategy will be to collect (through nondestructive means) wood samples of selected tropical tree species from sites in Indonesia and Thailand with pronounced rainfall seasonality. The samples will be rigorously cross-dated and developed into final chronologies. These chronologies will then be employed in dendroclimatic modeling and reconstruction of Southeast Asian climate over recent centuries.
