Acquisition and testing of geophysical data from Lake Issyk-Kul, Kyrgyzstan

在吉尔吉斯斯坦天山山脉的伊塞克湖进行的拟议研究侧重于两个主要目标；(i)一次地震调查，为湖泊沉积物的总厚度提供证据，并深入了解湖泊及其沉积物的构造和沉积历史，以便确定未来ICDP钻探地点的适当位置，并为各自未来ICDP沉积物岩心的解释提供背景信息；（ii）测试Issyk-Kul沉积物岩心中记录的古磁信号的质量，以便为该湖未来ICDP沉积物岩心的较老部分建立可靠的年龄模型。这些知识对于一个拟于2010年1月在ICDP框架内提交的深层钻探项目（测试气候和构造之间的因果关系：伊塞克湖过去几百万年的案例研究）至关重要。

The proposed study in Lake Issyk-Kul in the Tien Shan Mountain Range in Kyrgyzstan focuses on two main goals; (i) a seismic survey providing evidence for the total thickness of the lacustrine sediments and insight into the tectonic and depositional history of the lake and its sediments in order to identify appropriate locations for future ICDP drill sites and give background information for interpretation of the respective future ICDP sediment cores, and (ii) test the quality of paleomagnetic signals recorded in Issyk-Kul sediment cores to in order to build reliable age models for the older parts of future ICDP sediment cores of this lake. This knowledge is essential for a proposed deep drilling project (Testing the causal link between climate and tectonics: A case study from Lake Issyk-Kul covering the past few million years) that will be submitted in January 2010 within the framework of ICDP.
