Approximations to wave scattering by an ice sheet of variable thickness over undulating bed topography
This paper describes an investigation into the effect on wave propagation of an ice sheet of varying thickness floating on water of varying depth. A variational principle equivalent to the governing equa-tions of linear theory in three dimensions is given, forming the basis of a Rayleigh-Ritz approx...

| Summary: | This paper describes an investigation into the effect on wave propagation of an ice sheet of varying thickness floating on water of varying depth. A variational principle equivalent to the governing equa-tions of linear theory in three dimensions is given, forming the basis of a Rayleigh-Ritz approximation. Here we invoke the mild-slope approximation in respect of the ice thickness and water depth variations |
