Dekadische bis orbitale Klimavariabilität im Indo-Pazifischen Wärmepool während der vergangenen ca. 650.000 Jahre
Zusammenfassung der Projektergebnisse
The investigations have contributed significantly to the ICDP-funded „Towuti Drilling Project“ (TDP) in Indonesia. The scientific expectations of the DFG project were widely fulfilled, namely: (i) continuative investigations of a sediment core from the TDP pre-site survey provided information concerning climate-controlled lake-level fluctuations over the past ca. 29 ka on orbital and millennial timescales, (ii) the participation on the TDP drilling operation and core processing provided unique sediment samples that will allow to reconstruct the climate history in the Indo-Pacific Warm Pool over several glacial-interglacial cycles, according to recent data probably over the past ca. 800 ka, (iii) the investigations of lake surface sediment samples taken during the drilling operation has provided deep insights into the modern processes of sediment formation under the current, i.e. known climatic and environmental conditions and (iv) the investigations of the ~136 m long drill core from TDP Site 2 has provided first information on the depositional history in the northern basin of Lake Towuti, albeit still with insufficient age control. In several publications, the first comprehensive long-term depositional history in Lake Towuti is presented, and its climatic and tectonic control, based upon the results from the TDP sediment cores. These publications rely on final age models for the drill cores, which still are under construction.
