AbstractThis report presents a summary of field activities conducted in 2017 in the Mackenzie corridor Northwest Territories (NWT). Air temperature, ground-thermal and active-layer data acquired from permafrost monitoring sites visited in 2017 are provided in graphical and tabular format. Ground temperature records for the 2007-2017 period are also presented and indicate that permafrost is generally warming throughout the corridor and for a majority of sites, permafrost is currently warmer than the baseline established during the International Polar Year (2007-09). The data presented provide essential baseline information that can be utilized by stakeholders and others for various purposes such as land management activities, regulatory processes and design of northern infrastructure. This report will be distributed to community organizations and stakeholders in the study region to provide an update on field activities.
Summary(Plain Language Summary, not published)
This report presents a summary of field activities conducted in 2017 in the Mackenzie Corridor, Northwest Territories. Air temperature, ground thermal and active layer data acquired from permafrost monitoring sites visited in 2017 throughout the corridor are provided in graphical and tabular format. Information about the changes in ground temperatures and active layer thickness over time is also presented. Results indicate that permafrost generally continues to warm at most sites in the corridor. Active layer thickness has generally increased since 2008 and exceeded the long-term mean since 2009. This report will be distributed to community organizations and stakeholders in the study region to provide an update on field activities. The ground thermal and active layer data presented provide essential baseline information that can be utilized by stakeholders and others for purposes such as land management activities, regulatory processes and design of northern infrastructure.
