| Comment |
The seasonally thawed layer is synonymous with the active layer in areas with permafrost where seasonal freezing commonly reaches the permafrost table. Thawing progresses from the surface downward, whereas freezing progresses both downward from the surface and upward from the permafrost table. The seasonally thawed layer usually has a negative mean annual ground temperature.
