a Volumetric ice content profile in Richardson Mountains/Peel Plateau region in NWT28 (shown is the median of ground ice volume from 10 permafrost cores and averaged in 0.5 m bin interval) compared with a 50:50 mixture of Chena silt and Inuvik clay type sediment. b Volumetric ice content profile at Friis Hills27 compared with the negative depth derivatives of water speeds (dWSREGO/dZ) of Fujinomori soil type. c Gravimetric ice content profile at Beacon Valley26 compared with the negative depth derivatives of water speeds (dWSREGO/dZ) of Lebanon gravel. The negative depth derivatives of water speeds (dWSREGO/dZ) are used to indicate where ice accumulates by freezing or is removed by melting. Table 3 lists values of all parameters used in the WATEREGO ensemble simulation, in the square brackets are the mean annual ground surface temperature and its amplitude (in K) and the geothermal gradient (in K per 100 m). The colors of the lines in panels b and c correspond to the color of the x-axis titles. Note the change in scale for dWSREGO/dZ in the upper few meters.
