An updated assessment of ground ice and permafrost geology-related observations based on seismic shothole drillers' log records, Northwest Territories and northern Yukon; Geological Survey of Canada, Open File 7061, 1 DVD. doi:10.4095/290974 Abstract: 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, 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. Purpose: Provided as an output of Natural Resources Canada’s Climate Change Geoscience Program Supplemental_Information: Database and GIS constructed from individual seismic shothole litholog records providing lithostratigraphic information on massive ice, ground ice, and other permafrost geology-related lithostratigraphic observations. Data extends throughout the Mackenzie corridor, Mackenzie Delta, Northwest Territories, and northern Yukon, covering parts or all of NTS map areas 85, 95, 96, 106, 107, 116, and 117.
