Thaw depth

From Fiswiki

An illustration of the range in temperatures experienced at different depths in the ground during the year. The active layer (shown in grey) thaws each summer and freezes each winter, while the permafrost layer remains below 0°C.

Thaw depth or thaw line is the level down to which the permafrost soil will normally thaw each summer in a given area. The layer of soil over the thaw depth is called the active layer, while the soil below is called inactive layer.
