抽象。Towuti钻探项目（TDP）是一项国际研究计划，其目标是通过对印度尼西亚苏拉威西岛南部Towuti湖的科学钻探，了解热带西太平洋的长期环境和气候变化，地质和环境变化对水生生物分类群生物进化的影响，以及富含金属的超镁铁质湖泊沉积物的地球微生物学和地球化学。Towuti湖是马利利湖系统下游端的一个大型构造湖，该湖系统由五个高度生物多样性的湖泊组成，是东南亚最古老的湖泊之一。2015年，我们使用国际大陆科学钻探计划（ICDP）深湖钻探系统（DLDS）在托乌蒂湖进行了科学钻探计划。我们从11个钻井现场回收了总计1018米的岩心，水深从156米到200米不等。采收率平均为91.7%，最大钻井深度为湖底以下175米，穿透了盆地的整个沉积填充物。岩心和钻孔测井的初始数据表明，这些岩心记录了高度动态的构造和湖沼系统的演变，并清楚地表明了更新世中期至晚期的轨道尺度气候变化。
Abstract. The Towuti Drilling Project (TDP) is an international research program, whose goal is to understand long-term environmental and climatic change in the tropical western Pacific, the impacts of geological and environmental changes on the biological evolution of aquatic taxa, and the geomicrobiology and biogeochemistry of metal-rich, ultramafic-hosted lake sediments through the scientific drilling of Lake Towuti, southern Sulawesi, Indonesia. Lake Towuti is a large tectonic lake at the downstream end of the Malili lake system, a chain of five highly biodiverse lakes that are among the oldest lakes in Southeast Asia. In 2015 we carried out a scientific drilling program on Lake Towuti using the International Continental Scientific Drilling Program (ICDP) Deep Lakes Drilling System (DLDS). We recovered a total of ∼ 1018 m of core from 11 drilling sites with water depths ranging from 156 to 200 m. Recovery averaged 91.7 %, and the maximum drilling depth was 175 m below the lake floor, penetrating the entire sedimentary infill of the basin. Initial data from core and borehole logging indicate that these cores record the evolution of a highly dynamic tectonic and limnological system, with clear indications of orbital-scale climate variability during the mid- to late Pleistocene.
