An analysis of the thermomechanical behavior of an ice shelf is presented. The mathematics is simplified by simulating the transverse temperature distribution by a realistic shape function thereby replacing the local energy equation by a time-dependent, total energy balance condition which accurately models the ocean-ice and ice-atmosphere heat exchange processes. The emerging steady state theory correlates a dimensionless combination of accumulation rate, horizontal strain rate and thickness with heat flux and surface temperature and shows fair agreement with published data. A time-dependent small perturbation analysis further shows that the criterion of stability of the solutions is expressible in terms of this dimensionless parameter. Stable and unstable flow regimes can be separated and physically interpreted. Show more
