Abstract

Iceberg calving contributes roughly half of the net freshwater flux from the Antarctic ice sheet to the Southern Ocean, with impacts on the local, regional, and global oceanography. One potentially dominant driver of calving is through wave erosion at the fronts of ice shelves. This erosion results in underwater ice “benches” that jut out beyond the above-water ice cliff. These benches often lead to upward bending…
