Penetration of heat into permafrost-bearing sediment

Thawing permafrost acts as a thermal buffer, slowing the diffusion of heat into sediment. Once dissociated, however, gas released at the top of the hydrate stability zone can migrate through the sediment without reentering the gas hydrate stability zone. This case is similar to the shallow marine case illustrated in Figure 3.6. Gas liberated from dissociation at the base of gas hydrate stability will likely reform as gas hydrate as it migrates up through the gas hydrate stability zone.
