  • Freeze-up of Sea Ice

    Typical advance of sea ice over from late summer to late winter is shown on this map. Sea ice is any form of ice that is found at sea and has originated from the freezing of seawater. Formation of sea ice begins in mid-September in the Canadian Arctic and advances southward through the onset of...

  • Break-up of Sea Ice

    The typical retreat of the sea ice cover from the late winter to late summer is shown on this map. Sea ice is any form of ice that is found at sea and has originated from the freezing of seawater. Melting of sea ice begins in spring in the Gulf of St. Lawrence and East Newfoundland, retreating...

  • 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...

  • 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...

  • Distribution of Freshwater - Glaciers and Icefields

    Glaciers and icefields are huge masses of ice, formed on land by the compaction and re-crystallization of snow, that move very slowly down slopes, or move outward due to their own weight. In Canada, an estimated area of 200 000 square kilometres, or about 2% of the country’s area is covered by...

  • Probability of the annual minimum snow and ice (MSI) presence over Canada

    Snow and ice are important hydrological resources. Their minimum spatial extent here referred to as annual minimum snow/ice (MSI) cover, plays a very important role as an indicator of long-term changes and baseline capacity for surface water storage. The MSI probability is derived from sequence...
