Termini of calving glaciers as self-organized critical systems
This article focuses on the discrete nature of calving and the understanding of the process itself. Based on calving data reaching from small events on glaciers up to the size of ice-shelves, the authors give strong arguments that calving fronts behave as self-organized critical systems that switch from sub-critical stable to super-critical calving modes. The paper also includes a preliminary example on how such a discrete model that was used to underline the argument above could be coupled to Elmer/Ice in order to switch between continuum models in the sub-critical stage to the particle model in the super-critical mode in order to more realistically represent calving compared to continuum models.
