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

位于吉尔吉斯斯坦中亚共和国的伊塞克湖是世界第二大高海拔湖泊。伊塞克湖位于天山高处，是一个闭盆型湖泊，近岸和近海碳酸盐沉积丰富，湖平面大范围变化历史悠久。Issyk-Kul位于盛行西风带影响下的一个临界点，沿PEP II横穿冬季西伯利亚高压环流和夏季西南印度低压。即使由于这些主要大气要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泊水平的变化中。伊塞克湖古气候项目的基本目标是建立过去20-25ka伊塞克湖湖水位变化的高分辨率多代理记录，并通过这样做，澄清这一亚洲大陆相对鲜为人知的重要部分的第四纪晚期气候变化记录。

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.
