Figure 4.6. Long-term change in active-layer thickness in six Arctic regions as observed during the Circumpolar Active Layer Monitoring project. Data are presented as annual percentage deviations from the mean value for the period of observation. Thaw depth observations from the end of the thawing season were used. Only sites with at least 10 years of continuous thaw depth observations are shown (Romanovsky et al., 2015).
