Abstract
Specially designed temperature probes using copper-constantan wire were installed in 3 vertical holes on and near a paved runway at Defence Research Establishment Suffield (DRES) in south-eastern Alberta. Earth temperatures were monitored during the winter of 1970-71. The data obtained showed that, for that particular winter, the maximum depth of below-freezing temperatures was 64 inches. This occurred under the edge of the runway on the 9th of March 1971. In addition, they showed that surface temperatures were well below freezing for several weeks before the soil temperatures dropped below freezing at a depth of one foot, the freezing front under the runway advanced downward at a slower rate than it did at the edge of the runway and the thawing fronts advanced from above and below to meet at a depth of approximately 3 feet below both the runway and the prairie.
