Short summary
We investigate how waves may erode the front of Antarctica's largest ice shelf, Ross Ice Shelf, and how this results in bending forces that can cause deformation of the near-front shelf and trigger intermediate-scale calving (with icebergs of lengths ∼ 100 m). We compare satellite observations to theoretical estimates of erosion and ice shelf bending in order to better understand the processes underlying this type of calving and its role in the overall ice shelf mass flux.
