EFFECTS OF A SNOW PILLOW ON HEAT AND VAPOR TRANSPORT IN THE BLACK SPRUCE/PERMAFROST ENVIRONMENT OF INTERIOR ALASKA

A standard 4 X 5 foot metal snow pillow was installed in the black spruce/permafrost environment of Interior Alaska and instrumented to determine if the presence of the pillow had any appreciable effects on the thermal regime, and the possible migration of water vapor from the thick organic soils into the snowpack during the extended cold winter period. In hopes of separating the two effects, should they both exist, a double layer of 4 mil plastic sheeting of the same size and shape as that of the pillow was installed at the same site. The results of the first winter's operation indicate that the pillow had minor effects on the temperature profiles from the air/snow interface to a point 30 cm below the soil surface. The primary effect appeared to be one of slowing the rate of temperature fluctuation.
