AbstractATM-9814953Johnson, Thomas C.University of MinnesotaTitle: The Paleoclimate Record in Sediment Cores from Lake Issyk Kul, KyrgystanThis award supports the analysis of sediment cores recovered from Lake Issyk Kul, Kyrgystan. Ostracode assemblages in four of these cores will be analyzed for paleoclimate based on oxygen and carbon stable isotopes, trace element composition and faunal abundance of the ostracode assemblages. Issyk-Kul is located on the edge of the Tien Shan Mountains in Kyrgystan, at an elevation of just over 1600 m. It is in a region of the Asian continent where good paleoclimate records are scarce and much needed. The key questions to be asked relate to the timing and intensity of climatic change in this remote region of central Asia over the last 10,000 years.

美国明尼苏达大学，托马斯C.约翰逊，题目：吉尔吉斯斯坦伊塞克湖沉积岩芯中的古气候记录该奖项支持对吉尔吉斯斯坦伊塞克湖沉积岩芯的分析。 将根据氧和碳稳定同位素、微量元素组成和介形虫组合的区系丰度，对其中四个岩心中的介形虫组合进行古气候分析。 伊塞克湖位于吉尔吉斯斯坦天山山脉的边缘，海拔略高于1600米。 它位于亚洲大陆的一个地区，良好的古气候记录稀缺且急需。 要问的关键问题涉及过去10，000年来中亚这一偏远地区气候变化的时间和强度。
