Discussion

Laboratory experiments reveal how gas hydrates alter thermal conductivity and permeability in permafrost.

Gas hydrates enhance the strength and resistivity of permafrost while reducing permeability and heat transfer rates.
Laboratory studies show hydrate-bearing permafrost has a lower thermal conductivity compared to hydrate-free ground.
Presence of gas hydrates affects electrical resistivity, which increases with higher hydrate content in permafrost.
Gas hydrates influence the moisture composition in permafrost systems, altering physical property dynamics.

Chuvilin et al. (2025) studied this question.
