In ice-covered oceans, waves play a very important role in sea ice processes and offshore operations. The retreat of sea ice coverage in the Arctic increases the wave intensity; hence it is necessary to model wave conditions in the Arctic. In this thesis, the wave propagation characteristics in ice-covered oceans are studied systematically. A laboratory experiment was first carried out to study the wave propagation through ice covers consisting of a frazil and pancake ice mixture. The comparison between the experimental results and the two-layer viscous model shows that modeling the tested ice cover as a viscous fluid is not sufficient to describe the observed dispersion relation and amplitude attenuation. Based on the ice morphological structure and wave propagation characteristics in the marginal ice zone, a viscoelastic model is proposed to describe the propagation of gravity waves under various types of ice cover. It is shown that the viscoelastic model bridges the gap among the existing models and provides a unified tool for wave-ice modelers. In view of multi-mode coexisting in the transition elasticity regime, the Eigenfunction Expansion Matching Method (EEMM) is proposed to solve the amplitude of each mode. The resulting "full" solutions predict wave characteristics in the whole range of elasticity. Then, the viscoelastic model is applied to the laboratory experiment to inversely determine the viscosity and elasticity of the tested ice covers. Ways to overcome the challenges in validation and parameterization of the viscoelastic model using the laboratory experiment are further discussed.
