Self-organized criticality in the iceberg calving process / David B. Bahr.

Title: Self-organized criticality in the iceberg calving process / David B. Bahr.
Author(s): Bahr, David B.
Date: 1993.
In: Eos : transactions, American Geophysical Union. (1993.), Vol. 74(43, supplement) (1993)
Abstract: Abstract. Up to now, iceberg calving process has seemed to be largely random. However, by using simple set of mechanical properties and observations, probabilistic cellular automata can be constructed to model steady-state calving process. Model is successful in predicting general morphology of calving terminus and predicts that width-averaged calving velocity will be constant over long time periods. Model reaches state of "self-organized criticality" where time and spatial scales are absent, and random perturbations of terminus cause natural (self-organized) evolution back to same marginally stable, critical state.
