Research Abstract

In this study, we reconstruct the precise magnitude and timing of ice sheet retreat at the Sor Rondane Mountains in Dronning Maud Land, East Antarctica, based on detailed geomorphological survey and cosmogenic exposure dating. Our data show ~570 m of ice sheet thinning in this region since early Pleistocene. The most recent deglaciation started at 14 ka, and may continue until today, suggesting that the EAIS of Dronning Maud land is unlikely to be a major contributor to Meltwater Pulse 1A.
