Timing and amplitude of Antarctic ice level changes as response to past climate fluctuations are a major issue in paleoclimatology. In this study, we determined surface exposure ages with in situ produced cosmogenic nuclides (10Be, 21Ne) of four erratic boulders from a pre-last glacial deposit in th...
