| Abstract/Notes | Field observations of soil temperature, moisture regime, and frost heave in silty clay hummocks at Inuvik, Northwest Territories, over the fall and early winter reveal that a significant amount of moisture migration and frost heave occurs within frozen soil at temperatures down to β2.4Β°C. The field data are analysed using thermodynamic considerations, and the apparent hydraulic conductivity is determined as a function of negative temperature. The conductivity falls from near 7βΓβ10β9βmβsβ1 above 0 Β°C to about 3.5βΓβ10β12βmβsβ1 at β1 Β°C, then remains fairly constant down to β2.4 Β°C. The observed decrease in heave with time is explained in terms of a diminishing water supply at the base of the active layer. |
