Abstract : The feasibility of tunnel detection by trace gas analysis was investigated at the USA CRREL permafrost tunnel near Fox, Alaska. Under favorable conditions, the presence of an odor unique to the tunnel could be sensed at least 200 yards downwind from the air vent. Under extremely unfavorable conditions, trace gases identified in the tunnel were present 40 years downwind from the air vent in concentrations 10 to 100 times greater than were observed upwind. These results supported the principle of detection by trace gas analysis.
