Mathematical description of the sea ice melting is given. The problem statement assumes decreasing of solid fraction simulating an ice of two-phase media up to formation of fully liquid area with moving interface. In the framework of one-dimensional approach and a number of simplifications, the self-similar solutions for different variants of border heating have been derived and analyzed. The criteria of the sea ice layer recrystallization have been obtained. A qualitative comparison of the results with experimental data is presented.
