Résumé(disponible en anglais seulement)
This publication utilizes seismic shothole drillers' litholog records to document ground ice and massive ice thickness and extents in the Northwest Territories and northern Yukon. It also provides estimates of permafrost thickness in areas of thin extensive and sporadic discontinuous permafrost, identification of unfrozen sediments (existing and relic taliks) at depth in areas of thick permafrost cover, and depths of surface thaw in offshore Mackenzie Delta sediments.
Limitations in the seismic shothole drillers' log data are clearly recognized in their application to permafrost studies, yet they nonetheless provide a rich archive of information that can be correlated with established monitoring sites and expand regional interpretations. The information interpreted from the drillers' log records will perhaps best serve as guides to future permafrost research by identifying key areas of interest and/or anomalous permafrost conditions that can be studied and tested in follow-up field research.
