Physical Modeling of the Formation and Chemical Composition of Cryogenic Structures in Marine Sediments Within the Shelf Zone

The paper presents the findings of a physical model of the process of ground freezing under various boundary conditions, specifically in a subaquatic environment in a shallow zone. The study analyzed the characteristics of ice formation within the ground, the redistribution of salt, as well as the temperature, moisture content, and electrical resistivity distribution at different depths during the experiment. This allowed for the determination of a certain correlation between these parameters when the ground freezes in a subaquatic setting. To address this problem, a laboratory setup was developed and constructed, enabling experimental investigations to be conducted under well-controlled boundary conditions. Measuring the electrical resistivity of the ground during the experiments yielded values that, through modeling, can implicitly be linked to the physical and chemical characteristics of the ground on a given territory. This, in turn, could be confirmed through full-scale geophysical surveying of the area.
