On the surface of the permafrost lies the so-called active layer, which thaws in summer and allows plants to grow: grasslands, forests, or wetlands with ponds and lakes. In some areas, the landscape ...

The results show that the freeze-thaw changes of permafrost active layer have a direct impact on the water interaction and transformation relationship of "precipitation—soil water—permafrost ...

Permafrost—ground that remains frozen year-round—is capped by a few feet of dirt and plant detritus. Called the active layer, this soil normally thaws each summer and refreezes in winter ...
