Abstract:Topographic variability beneath ice sheets regulates ice flow, basal melting, refreezing processes, and meltwater drainage. The preservation of old ice layers and basal ice stratigraphy is sensitive to these subglacial processes, and Dome Fuji, inland East Antarctica, is one of the few regions where 1.5‐Ma old ice can be preserved for investigating a major climatic change that occurred in the mid‐Pleistocene. We used stochastic simulation methods and radar data to generate an ensemble of simulated bed topograp… Show more
