Glaciochemistry of an Ice Core from the Tien Shan: Tracking Environmental Change in Central Asia

Ice cores provide a unique repository for records of past global change. A 160 meter ice core, recovered from the Tien Shan, in Central Asia has allowed for the reconstruction of atmospheric dust. Crucial to the understanding of atmospheric dust content, is the ability to track changes in source region. The ice core location is unique in that it lies directly downwind of one of the worlds worst environmental disasters, the Aral Sea. Here we present the investigation of atmospheric dust and dust storm activity in Central Asia through the use of an ice core.
