The article is devoted to peculiarities of formation of the cryogenic structure of modern coastal sediments using laboratory simulation. The authors have conducted comparative analysis of the results of laboratory and field studies and have shown how the cryogenic structure of coastal sediments depends upon the composition, salinity and moisture. They have also analyzed redistribution of soil moisture in different types of soils and the features of ice formation in the zone of contact between shore ice and sea bottom.
