    Permafrost

    Permafrost occurs when the ground remains at or below a temperature of 0oC for a minimum period of two years. Permafrost occurs not only at high latitudes but also at high altitudes. Almost all of the soil moisture in permafrost occurs in the form of ground ice, which in turn occurs in several...

    Permafrost, Glaciers and Sea Ice (Nunavut)

    Nunavut’s cold climate makes it a territory consisting of mostly barren land and permafrost. Permafrost is soil or rocks whose temperature remains at or below the freezing point for a long period of time. Glaciers, a mass of snow and ice that does not melt from year to year prevail in the...

    Active Layer - Ukkusiksalik

    Permafrost and the active layer (the soil layer above the permafrost that freezes and thaws annually) are directly affected by climate. It is anticipated that rising temperatures in the Arctic will lead to permafrost warming/melt and thickening of the active layer. Probable impacts of permafrost...
