In a recent article published in Nature Geoscience, Paul Wilcox and Michael Meyer (Quaternary Research Group, Innsbruck), together with Daniela Festi (Geosphere Austria), present a rare – OSL dated – terrestrial meltwater archive from a karstified glacial outwash plain in Alaska. This archive captures immense meltwater pulses from the Cordilleran Ice Sheet as it discharged into the Northeast Pacific approximately 20,000 and 17,000 years ago. The findings shed new light on the potentially significant role of the Northeast Pacific during the transition from glacial to interglacial climate conditions.
