Earth’s ice sheets are changing rapidly in response to anthropogenic climate change, and these changes are modulated by their basal topography. Visualizing the landscape that lies beneath the East Antarctic Ice Sheet not only allows glaciologists to improve model projections of future ice sheet change, but also provides a glimpse of a landscape hidden beneath ice. Paxman et al. [2026] used…
