Reconstructing the biogeochemical response of Indonesian coastal ecosystems to environmental change during the late Quaternary as recorded by marine sediment cores along the Sumatra - Java - Flores transect (BIORESICO)

全球气候变化是区域变化的镶嵌体，在很大程度上取决于气候与生态系统之间的区域反馈。因此，区域气候和生态系统之间的时间/因果关系需要调查，以进一步我们的过程中的理解与全球变化。这是在全球变化加速的情况下改进对未来发展预测的先决条件。在过去的十年里，热带地区在全球气候变化中发挥着重要作用。这一建议的重点是印度尼西亚群岛，也被称为海洋大陆。虽然被认为是一个关键区域，但关于拟议研究区过去气候变化和陆地和海洋生态系统反应的信息很少。在那里，季风、印度洋偶极子和厄尔尼诺/南方涛动的变化影响了陆地的降水和植被以及海洋的表面环流和上升流，从而影响了海洋和陆地有机物的沉积。从印度尼西亚苏门答腊岛和爪哇岛到弗洛雷斯的印度洋边缘的沉积物岩心是在“索内”号考察船SO-184和SO-189号考察期间收集的，提供了第四纪晚期环境变化的高分辨率档案。一套地球化学工具与孢粉学和古海洋学信息相结合，将能够重建该地区陆地和海洋生态系统对过去气候变化的反应。

Global climate change is a mosaic of regional changes to a large extent determined by region-specific feedbacks between climate and ecosystems. Therefore, the temporal/causal relationships between regional climates and ecosystems need to be investigated in order to further our process understanding related to global change. It is a prerequisite for improving predictions of future developments in a scenario of accelerated global change. Over the past decade it became obvious that the tropics play an important role in global climate change. This proposal focuses on the Indonesian archipelago, also termed the maritime continent. Although considered a key region only little information exists on past climate changes and the response of terrestrial and marine ecosystems in the proposed study area. There, changes in the monsoons, the Indian Ocean Dipole (IOD) and the El Niño/Southern Oscillation (ENSO) have affected precipitation and vegetation on land and surface circulation and upwelling in the ocean and hence the deposition of marine and land-derived organic matter. Sediment cores from the Indian Ocean margin off the Indonesian islands Sumatra and Java to Flores collected during RV SONNE cruises SO-184 and SO-189 provide highresolution archives of environmental change during the late Quaternary. A suite of biogeochemical tools in combination with palynological and paleoceanographic information will allow to reconstruct the response of terrestrial and marine ecosystems to past climate change in that region.
