AbstractThis 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, and the identification of unfrozen sediments (non-ice-bonded permafrost and/or existing and relic taliks) in areas of thick permafrost cover, and in offshore Mackenzie Delta sediments. Limitations of the seismic shothole drillers' log data are clearly recognized in their application to permafrost studies (reflecting the generally shallow (10 - 60 m) shothole depth, and logging imprecision). They nonetheless provide a rich archive of information that in some cases represents orders of magnitude more records than previously existed, that can be correlated with established monitoring sites and used to 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, lithostratigraphic associations, and anomalous permafrost conditions that can be studied and tested in follow-up field research.
