Flexural-gravity waves on floating stratified ice.

Abstract

Flexural-gravity waves in the 3-50 ms period range were recorded on floating layers of ice ranging from 6-52cm in thickness. These inversely dispersive waves are analogous to Rayleigh waves propagating on a multi-layered structure. Therefore, flexural-gravity wave dispersion curves can be calcualted by the well-known Haskell-Thompson method. This approach allows the effects of snow layers and stratification of the ice to be evaluated.-from Author
