Permafrost is defined as rock or soil that remains below 0°C for at least two consecutive years. Along the latitudinal transect, it ranges from extensive continuous thick permafrost to relict permafrost located in isolated underground patches. Permafrost contrasting states are primarily based on the extent of frozen ground across the landscape (30 km X 30 km). States are also described using the characteristics (temperature, permafrost thickness, water and ice contents) of their different layers (active layer, perennially frozen ground and taliks – see Supplementary Note 1 for definitions).
