印度尼西亚穿越流是西太平洋和印度洋之间热量传输的重要载体 ,穿越流的活动由潜在地影响ElNino和季风现象进而影响到全球气候变化 .通过对爪哇海SHI90 0 6岩心LGM以来氧同位素、有孔虫与CaCO3 沉积量、浮游有孔虫浅层水种与深层水种比值反映的古温跃层变化等的研究 ,得出结论 :研究区末次冰期氧同位素 2期穿越流活动微弱 ,冰后期穿越流活动增强 ;特别是冰消期终止期ⅠA,穿越流活动由弱迅速增强 ,是冰川消融、海平面上升 ,印度尼西亚岛弧古海水通道开放的结果 .
Indonesia is an important carrier of heat transfer between the western and Indian Oceans and its activity is influenced by the potential impact of El Niño and monsoon phenomena on the global climate change.Through the Oxygen Isotopes to the LGM of SHI90 0 6 core in the Java Sea, The amount of sediment, the amount of larvae and CaCO3 deposition, the change of paleotherm reflected by the ratio of shallow water species and deep water species of planktonic foraminifera, concluded that the oxygen flow in the last glacial stage of the study area was weak and the post-ice traversal The flow activity is enhanced. Especially during the expiration of ice ablation ⅠA, the weakening and rapid increase of cross-flow activities are the result of glacial melting, sea level rise and the opening up of the ancient island’s seawater channel in Indonesia.
