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 corresponds to any soil or rock whose temperature has remained below 0°C for years. In the extreme north of Quebec, it is omnipresent and very thick. At its northern margin, further south, it appears in the landscape as isolated thin plates, generally less than 10 m thick. Permafrost contains ice in various forms, the origin of which is closely linked to the sedimentary characteristics and drainage conditions of the terrain. The mapping of permafrost conditions for Nunavik (territory located north of the 55th parallel), carried out by the Centre d'études nordique of Université Laval, was done by applying a simple model called TTOP (Temperature at the Top Of Permafrost) for the period from 2000 to 2016. The model results are presented in the form of a raster file that illustrates the distribution of continuous, discontinuous, and sporadic permafrost, as well as isolated islands. Under the effect of global warming or ill-adapted anthropogenic activities, permafrost heats up, or even thaws, leading to settlements and ground movements affecting ecosystems as well as infrastructure. Thus, the susceptibility of the territory to thermokarst subsidence was evaluated for the same territory taking into account the ice content and the temperature at the top of the permafrost. A raster file of the territory's susceptibility to permafrost thawing ground subsidence shows three susceptibility classes (high, moderate, and low) as well as areas that are generally permafrost-free.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This layer shows the delimitation of the perimeter of the special intervention zone (ZIS) of the decree named “Declaration of a special intervention zone in order to promote better management of flood zones”. This zone was created using various data sources showing the 2017 and 2019 flooded areas. Since the adoption of Decree 817-2019, this dataset is no longer in force. For more information on flood zone mapping in Quebec, consult the Information available on the Ministry's website using the following link: http://www.cehq.gouv.qc.ca/zones-inond/zone-intervention-speciale.htm**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
