Nonlinear waves in ice sheets Philippe, Guyenne


This talk concerns the mathematical modeling and numerical simulation of waves in ice sheets as occurring, e.g., in polar regions. A three-dimensional Hamiltonian formulation for ice sheets deforming on top of an ideal fluid of arbitrary depth is presented and nonlinear wave solutions are examined. In certain asymptotic regimes, analytical solutions are derived and compared with fully nonlinear solutions obtained numerically by a pseudospectral method.
