Abstract: Based on a formulated mathematical model, numerical experiments were carried out to study the degradation of permafrost containing ice, accumulations of metastable preserved gas hydrates, and free gas under thermal and saline effects of solutions, taking into account the osmotic effect. Multivariate calculations were used to investigate the patterns and rates of permafrost degradation and methane release. A comparison of some model results with corresponding experimental data showed good agreement.

Keywords: permafrost, gas hydrates, ice melting, degradation, solutions, osmosis, mathematical model.
