Sublimation and Its Control in the CRREL Permafrost Tunnel.
The U.S. Army Cold Regions Research and Engineering Laboratory's permafrost tunnel at Fox, near Fairbanks, Alaska, was used to investigate the sublimation process in permafrost silt. The rate of increase in thickness of the dried silt layer from sublimation was found to be approximately 0.023 i...
