AB: Our study investigates methods of capturing wave-ice interactions in non-continuous sea-ice cover situations. Wave-ice interactions occur in the Arctic marginal seas where concentrations are less than 100% and individual ice floes and pancake ice are present. The concentration of ice floes directly affects the sea state by acting to filter wave energy. Since many existing wave models do not consider sea ice, these wave models do not accurately portray wave energy in marginal sea ice zones. For engineering considerations in the Arctic coastal zones, however, it is important to consider the influence of floating ice to more accurately describe wave propagation. We look into the work that has been done by such authors as Squire (2007) and Ogasawara and Sakai (2006). We also explore the boundary element method and the finite element method to analyze wave-ice interactions.
