Despite the importance of the Indonesian Archipelago to modern and future global environmental change little is known about its past. New high resolution sediment cores mostly collected during RV SONNE cruise SO-184 provide excellent environmental archives. In this project, late Quaternary (Marine Isotope Stage 1 to 3) environmental dynamics, will be studied using several marine sediment cores along the Sumatra - Java - Flores transect in tropical SW and S Indonesia, Studies of past environmental change and ecological response will provide important insights into understanding modern and future global changes. Of special interest are the reconstruction of last glacial and in particular Holocene (1) vegetation changes on a gradient from humid to seasonal climate, (2) climate changes to understand the dynamic of the Intertropical Convergence Zone (ITCZ), ENSO-Events and the Monsoon system, (3) changes of the marine currents including the Indonesian Throughflow (ITF) and its role in continental environmental changes, (4) fire history and its impact on ecosystems and (5) the human impact during the past to understand modern and future environmental changes and ecological response. Of particular interest will be also the environmental dynamics related to the discovery of Homo floresiensis which was recovered from late Quaternary deposits on Flores Island.

尽管印度尼西亚群岛对现代和未来全球环境变化具有重要意义，但人们对其过去却知之甚少。主要在 RV SONNE 巡航 SO-184 期间收集的新高分辨率沉积岩芯提供了出色的环境档案。在该项目中，将使用印度尼西亚西南部和南部热带苏门答腊岛 - 爪哇 - 弗洛勒斯断面沿线的几个海洋沉积物岩心来研究第四纪晚期（海洋同位素阶段 1 至 3）环境动力学，对过去的环境变化和生态响应的研究将提供理解现代和未来全球变化的重要见解。特别令人感兴趣的是末次冰期，特别是全新世的重建（1）从潮湿气候到季节性气候梯度的植被变化，（2）气候变化，以了解热带辐合带（ITCZ）的动态，ENSO事件和季风系统，(3) 洋流变化，包括印度尼西亚穿流 (ITF) 及其在大陆环境变化中的作用，(4) 火灾历史及其对生态系统的影响，以及 (5) 过去人类的影响，以了解现代和未来的环境变化与生态响应。特别令人感兴趣的是与弗洛勒斯人的发现相关的环境动态，弗洛勒斯人是从弗洛勒斯岛晚第四纪沉积物中发现的。
