项目摘要

Lake Issyk Kul is the world’s second largest mountain lake and occupies a deep basin in the Tien Shan range, Kyrgyzstan. The lake offers a record of continental climate spanning millions of years that is likely unmatched by any other source. An ICDP funded workshop took place in 2011 and revealed that additional scientific investigations comprising seismic and sedimentological studies in the lake basin are necessary to define specific drilling locations and depths for an ICDP full proposal.The here proposed project will provide missing sedimentological information from the lake basin, as it is requested in the workshop report. The main objectives of this project are to study in more detail the surface sediment distribution in Issyk Kul and Late Quaternary outcrops at its southern shore, which indicate lake level high-stands between ca. 43 and 25 ka. Moreover, the project aims to recover, for the first time, 6-10 m long sediment sequences comprising interglacial (Holocene) and Last glacial sediments from the abyssal part of Issyk Kul at water depths of more than 500 m. The investigation of (bio-)geochemical, mineralogical, and grain-size characteristics and their downcore variations and a correlation of the information with that derived from surface and outcrop sediments will help to examine, if Issyk Kul can provide a continuous high-resolution record of climate change and shifts in atmospheric circulation patterns, in phase relationships of local Alpine glaciers and continental ice sheet advances, and the roles of tectonics and climate change in affecting erosion rates in the catchment. This project seeks to overcome the missing knowledge of sedimentation characteristics and sedimentation rates from the abyssal part of Issyk Kul and to provide information on potential deep drilling sites in the central part of the basin, which is most likely the only site, which contains the entire history of basin back to several Myr ago. The project is fundamental to re-activate the ICDP Issyk Kul initiative. It will help to form a new team of international scientists, including members of the former initiative, but also new members, and to establish a deep drilling in the lake basin.
伊塞克湖是世界第二大高山湖泊,位于吉尔吉斯斯坦天山山脉的一个深盆地,该湖提供了长达数百万年的大陆性气候记录,这可能是任何其他来源所无法比拟的。 2011 年,并透露需要对湖盆进行额外的科学覆盖调查、地震和沉积学研究,以确定 ICDP 完整提案的具体钻探位置和深度。这里提出的项目将提供缺失的信息根据研讨会报告的要求,该项目的主要目标是更详细地研究伊塞克湖及其南岸晚第四纪露头的表面沉积物分布,该湖表明了高位。此外,该项目旨在首次恢复包括间冰期(全新世)和末次冰期沉积物在内的 6-10 m 长的沉积物序列。对伊塞克湖水深超过 500 m 的深海部分进行(生物)地球化学、矿物学和粒度特征及其下岩心变化的研究以及将这些信息与来自地表和露头沉积物的信息进行关联将有所帮助。检查伊塞克湖是否能够提供气候变化和大气环流模式变化、当地高山冰川和大陆冰盖进展的相位关系的连续高分辨率记录,以及该项目旨在克服对伊塞克湖深海部分沉积特征和沉积速率知识的缺失,并提供有关伊塞克湖中部潜在深钻地点的信息。该盆地很可能是唯一一个包含了几马币前盆地历史的地点,该项目对于重新启动 ICDP 伊塞克湖倡议至关重要,它将有助于组建一个新的团队。国际科学家,包括前倡议成员,也包括新成员,并在湖盆中建立深钻。
