The genesis and mechanism of the tabular ice formation in Arctic sea shore are the subject of heated debates. The field studies in the area of the White Sea have shown close correlation between the ground water level and the periodic oscillation of the sea level. This allows considering the processes related to coastal hydrodynamics as one of the basic factors of the additional moisture of ground and the formation of tabular ice near Arctic sea. Physical modeling of the one-dimensional ground freezing has revealed that a periodic ground water rise in a porous (water-permeable) frozen ground under a frozen (not permeable for water) layer leads to an increase in the ice content of the ground and forms ice horizon.
