Marine ice-cliff instability modeling shows mixed-mode ice-cliff failure and yields calving rate parameterization

Ice-cliff failure that leads to marine ice-cliff instability could accelerate Antarctic Ice Sheet retreat. Here, the authors use 3D glacier models to investigate ice-cliff failure, derive a retreat rate relationship, and quantify mélange back force necessary to suppress ice-cliff failure.
