Abstract

Data collected from northern Canada indicate that the temperature at which freezing occurs can vary substantially, even for the same site. The results indicate that any form of freeze-thaw event counting, in the absence of some indicator of the presence of water and that it actually froze, is flawed, as thermal conditions alone are not adequate to indicate the occurrence or not of actual freeze-thaw weathering events. These data suggest that evaluations of freeze-thaw occurrence based simply on thermal thresholds may be substantially in error
