Modeling of Thermodynamic Consolidation of Sea Ice Ridges Drifting in the Water with Changing Temperature

Oceanographic and ice conditions in the region of Spitsbergen Bank Barents Sea were investigated research cruises “Polarsyssel” 2017–2019. Trajectories drift constructed using GPS data buoys deployed on floes cruises. The duration season was analyzed charts. air temperature wind velocities meteorological stations Bear Island Hopen Island. Fieldwork drifting showed existence thick consolidated with drafts up to 8 m, which identified as completely sea ridges. presence such is dangerous for winter navigation along Bank. A model thermodynamic consolidation ridges formulated investigate evolution observed water temperatures used boundary top bottom surfaces rubble. It shown that regular interaction rubble Atlantic Arctic waters leads almost complete an initial macro-porosity 0.2 150 days.
