Abstract

1. A mechanism for the appearance of bending vibrations of the ice cover in the presence of dynamic interaction of ice floes during hummocking is suggested. 2. An equation defining the pressure in the surface wave propagating in the near-to-ice water layer in the presence of bending vibrations of ice cover is obtained. 3. The validity of the suggested hypothesis is confirmed by satisfactory agreement of experimental data with results of calculations of pressure in the near-to-ice water layer based on vertical displacement of the ice cover undergoing flexural vibration.
