Abstract
The overall goal of my research in Alaska and the Yukon Territory is to document the regional pattern of precipitation-evaporation change from the late Pleistocene to present using multiproxy methods at a network of lakes. During the first phase of this project lakes situated in terrain that remained unglaciated during the Last Glacial Maximum were selected to obtain the long records of environmental change. This is possible because only the alpine regions in Alaska were glaciated during the last ice age. These lakes include Burial Lake in northwestern Alaska and a pair of lakes, Birch and Jan, in central Alaska. During the second phase of the project two classifications of lakes were targeted to obtain high-resolution Holocene climate records: (1) closed basin lakes – Meli, Tangled Up, Seven Mile, Jackfish, and Wrong and (2) glacial-fed lakes – Summit, Blue, Dumbbell, and Peanut. Seismic surveys and core transects from shallow to deep water were combined to identify transgression and regression sequences and collect sediments to document and date these features. Cores with continuous sedimentary records from the central basin were analyzed using an integrated methodology that combined sedimentary analyses of fine-scale sediment features, sediment magnetic characteristics, elemental and isotopic geochemistry, and palynology.
