Short summary
Ice cliffs are steep, bare ice features that can develop on the lower reaches of a glacier where the surface is covered by a layer of rock debris. Debris cover generally slows the rate of glacier melt, but ice cliffs act as small windows of higher rates of melt. It is therefore important to map these features, a process which we have automated. On a global scale, ice cliffs have variable geometries and characteristics. The method we have developed can accommodate this variability automatically.
