Accounting of the internal structure of the ice hummock keel in thermodynamic calculations of the evolution of the consolidated layer
Materials from long-term field observations of the internal structure of ice hummocks in the Arctic seas were analyzed. Empirical expressions describing the porosity distribution of the underwater part of a newly-formed hummock depending on the depth and width of the keel had been derived. A two-dim...
