grl50187-sup-0003-2012GL054463ts03.txtplain text document0KContingency table used to test null hypothesis that the occurrence of unfrozen gravel is not associated with lake surface-area trend, degrees of freedom = 2, chi-square = 6.5, p-value = 0.039.
grl50187-sup-0004-2012GL054463ts04.txtplain text document0KContingency table used to test null hypothesis that the occurrence of frozen silt is not associated with the occurrence of expanding lakes, degrees of freedom = 1, chi-square = 3.9, p-value = 0.047.
grl50187-sup-0005-2012GL054463fs01.pdfPDF document34KHistograms of electrical resistivity (upper 10 m), from the airborne electromagnetic survey, at locations of the ground-based permafrost survey [Jepsen et al., 2012]. Actual counts were multiplied by normalization factors of 1.40 (permafrost not encountered) and 1.78 (permafrost encountered) to produce histograms with areas of unity. Curves are log-normal distributions having same mean and variance as the observed data.
grl50187-sup-0006-2012GL054463fs02.pdfPDF document146KMaximum lake area versus sublacustrine thaw states for (a) gravel-silt, (b) gravel, and (c) silt. Gravel-silt thaw states are defined in article Figure 3. Upper and lower numbers in the bars are the percentages of total lake surface-area in the study area and the number of lakes sampled by the airborne electromagnetic survey, respectively.
