Abstract: In the present paper the equations describing thermodynamic consolidation of ice rubble are formulated, model solutions are investigated and the time necessary for full consolidation of ice rubble is estimated depending on oceanic heat flux. Results of two laboratory experiments on thermodynamic consolidation of ice rubble submerged in sea water with different initial temperatures are also discussed in the paper. In the experiments cylindrical vessels filled with a mixture of ice rubble and water were insulated from the sides and from the bottom and placed in the cold room with temperature -5 C. Durations of the experiments were 12 hours and 15 hours. It was discovered that over the time of the experiments ice rubble submerged in the water with temperature above the freezing point consolidated faster than ice rubble submerged in the water at the freezing point.
