Abstract: A complete linear visco-elastic model has been developed to describe the propagation of gravity waves into various types of ice cover (Wang and Shen, 2010a). The results are based on the Voigt model. The two key parameters, viscosity and elasticity of an ice cover, are envisioned to depend on floe concentration and the ratio of ice floe size to wavelength. This theoretical model requires validation. Furthermore, to complete this model so that it can be used for geophysical scale applications, parameterization of viscosity and elasticity must be determined. In view of the complexity in conducting field studies, well-controlled laboratory experiments are effective alternatives. In this paper, theoretical predictions for dispersion and attenuation characteristics in the laboratory scale are presented. The issues that need to be considered in a laboratory test are also discussed.
