This study proposes a detailed model for ice sheets having a radially symmetric geometry. Governing relations are derived from first principles of physics, and the interactive effects of mechanical and thermal energy are taken into account. The resulting model is a nonlinear partial differential equation relating the temperature, velocity, and stress fields. Boundary conditions of accumulation rate, geothermal flux, sliding laws, and surface temperatures having been specified, and the model determines a steady state response in terms of ice sheet profile and internal temperatures, velocities, and stresses. We describe the computational methodology for numerically determining solutions from which one can assess the credibility of the model itself, and to the extent that it is credible, examine effects such as perturbing of external temperatures, accumulation rates, and so forth. Piloting examples illustrate this. Show more
