Past environmental changes by ice core studies
Scope
Recent progress of ice core studies has advanced our ability of recognizing and understanding global to local environmental changes on timescales from years to several hundred thousand years. We discuss environmental changes in the past on the basis of ice core studies. Studies on deep-sea cores, tree-rings and numerical modeling on similar time and spacial scales are welcomed. Studies on recording processes of paleoenvironmental signals and methods to extract them are also welcomed.
