Contained within the 5th Edition (1978 to 1995) of the National Atlas of Canada has a large that shows the extent of permafrost and abundance of ground ice; mapping units are based on physiographic regions. Point data on map give permafrost temperature and thickness for specific sites. The second, smaller, map shows the mean annual ground temperatures. Graphs show four shallow temperature profiles (to 25 metres depth), and four deep temperature profiles (to several hundred metres depth).

The National Ecological Framework for Canada's "Permafrost by Ecoprovince” dataset contains tables that provide permafrost information within the ecoprovince framework polygon. It provides permafrost codes and their English and French language descriptions as well as information about the percentage of the polygon that the component occupies. Permafrost is defined as a state of the ground, whether soil or rock, that remains at or below a temperature of 0° C for long periods (NRC, Permafrost Subcommittee, 1988). The minimum period is from one winter, through the following summer, and into the next winter; however, most permafrost has existed for much longer.

Permafrost loss is pervasive across northern circumpolar regions. The loss of frozen ground has profound impacts on water resources at varying spatial and temporal scales via changes to predominant hydrological processes, runoff pathways and entrainment rates of solutes and sediments. Consensus exists that permafrost loss will continue, and rates will vary spatially, but how hydrology and biogeochemistry will respond across large swaths of land remains largely unknown. Previous research elucidated small-scale processes or described circumpolar trends, with minimal cross-scale research.

Permafrost and snow are critical to the ecology of many northern ecosystems. They influence hydrology and vegetation and can dramatically affect the quality of wildlife habitat. In recent decades permafrost temperatures in North America have increased and snowfall and spring snow cover in the Arctic have declined. These trends are predicted to continue, although with regional and seasonal variability.

This dataset measures the temperature of the soil at 4 depths: 1 meter, 5 meters, 10 meters and 14 meters. This permafrost data is collected using Hobodata loggers that collect data at 12 hour intervals throughout the year. Field maintenance and station updates occur annually in late March and early April. The average temperature in the Arctic has increased at almost twice the rate of the rest of the planet in the past few decades, and the Arctic is now experiencing some of the most rapid and severe change on Earth.

This GIS dataset depicts the surficial geology of the Chipewyan Lake area (NTS 84A/NW) (discontinuous permafrost features). The data were created in geodatabase format and output for public distribution in shapefile format. These data comprise the permafrost polygon features of Alberta Geological Survey Map 572, Surficial Geology of the Chipewyan Lake Area (NTS 84A/NW).
