The Late Quaternary Paleoclimatic Archives of Lake Issyk-Kul, Kyrgyzstan: Calibration and Extension of the Sedimentological/Geochemical Proxy-Record

9905324伊塞克湖位于中亚吉尔吉斯斯坦共和国境内，是世界上第二大高海拔湖泊。伊塞克湖是一个位于天山高处的封闭盆地型湖泊，具有丰富的近海岸和近海碳酸盐沉积，并具有长期的大规模湖平面变化历史。伊塞克湖位于盛行西风影响下的关键位置，沿着冬季西伯利亚高压单体和夏季西南印度低压之间的PAGES-PEP II断面。即使是由于这些主要大气元素的位置或强度的气候变化而引起的水分和/或温度的细微变化，也应该强烈地记录在湖平面的变化中。伊塞克湖古气候项目（IKPP）的基本目标是建立一个高分辨率的多代理记录在过去的20-25万年伊塞克湖湖的水位变化，并在这样做，以澄清晚第四纪气候变化的记录在这个重要的和相对鲜为人知的亚洲大陆的一部分。

9905324Lake Issyk-Kul, in the Central Asian Republic of Kyrgyzstan, is the second largest high-altitude lake in the world. Issyk-Kul is a closed-basin lake located high in the Tien Shan, with abundant near shore and offshore carbonate sedimentation, and a long history of large-scale lake-level change. Issyk-Kul is found at a critical site under the influence of the prevailing Westerlies, and along the PAGES-PEP II transects between the winter Siberian High Pressure Cell and the summer Southwest Indian Low. Even subtle changes in moisture and/or temperature due to climatic shifts in the position or intensity of these major atmospheric elements should be strongly recorded in lake-level changes. The fundamental goal of the Issyk-Kul Paleoclimate Project (IKPP) is to create a high-resolution multi-proxy record of lake-level change in Lake Issyk-Kul over the past 20-25 ka, and in doing so, to clarify the Late Quaternary record of climatic change in this important and relatively little-known portion of the Asian continent.
