Description
Summary:The influence of ice cover on the propagation of internal waves is a practically important but poorly studied problem. It is a common assumption that the rigid lid (hereafter, RL) approximation, which filters out the surface mode and describes well the properties of internal waves, can be applied if the free surface is substituted by an ice cover. Since the vertical velocity at the surface is zero in the RL approximation, there should be no vertical displacements of the ice cover over the vertical; i.e., internal waves cannot be recorded on the basis of fluctuations of the ice cover under natural conditions.
