Thaw depth Thaw depth In soil science, the thaw depth or thaw line is the instantaneous level down to which the soil has warmed to zero degrees celcius. The active layer thickness is the maximum thaw depth over a period of two years. The layer of soil over the thaw depth is called the active layer, while the soil below is called permafrost. The term frost front refers to the varying position of the thaw line during the periods of freezing/thawing. The knowledge of the thaw depth is important for the two major reasons: its influence on the ecology and on construction
Centigrade (film) originally to go to another actor, but difficulties forced Cunningham to take the part himself. The script was written 17 years ago; Madison Graie suggested to Cunningham that they apply for the Directors Guild of Canada's "Kickstart Program" to make "Fahrenheit" ("Centigrade"'s original title).
