Study Site: Scotty Creek
Purpose: This study investigates the mechanisms contributing to permafrost thaw on ice-cored peat plateaux in subarctic Canada. To answer this question, freeze and thaw depths for four years (2011, 2015-2017) are presented, as well as micrometereological data recorded at half hour intervals on a Campbell Scientific CR10X data logger.
Abstract: Measurements of active layer thickness (ALT) are typically taken at the end of summer, a time synonymous with maximum thaw depth. By definition, the active layer is the layer above permafrost that freezes and thaws annually. This study, conducted in peatlands of subarctic Canada, in the zone of thawing discontinuous permafrost, demonstrates that the entire thickness of ground atop permafrost does not always refreeze over winter. In these instances, a talik exists between the permafrost and active layer, and ALT must therefore be measured by the depth of refreeze at the end of winter.
