| Abstract | The western coast of Hudson Bay in the Kivalliq region of Nunavut is undergoing significant infrastructure development associated with natural resources and community sustainability. Permafrost and
ground ice are important features of this landscape that can significantly affect land-based infrastructure. We have conducted scientific planning operations and fieldwork in Rankin Inlet and over the Kivalliq region of Nunavut as the preliminary
stage of research activity aimed at providing permafrost information and understanding permafrost conditions for this area. Recent fieldwork involved geomorphological observations, examination of surficial geological materials, and site selection for
establishment of permafrost monitoring stations. Initial sites in Rankin Inlet and at Ennadai Lake were instrumented with ground temperature sensors. Additional site locations have been chosen to represent a variety of conditions including developed
and undeveloped land, and different geological settings. Field observations will be used for analysis of satellite-based mapping of ground movement and landscape classification, with a major objective of the work being the development of methods for
regional permafrost characterization and understanding geological controls on permafrost conditions. |
| Summary | (Plain Language Summary, not published)
The Kivalliq region of Nunavut is undergoing infrastructure development associated with natural resources and community sustainability. Permafrost and
ground ice are important features of this landscape that affect infrastructure through influence on ground stability and drainage. Knowledge of permafrost conditions is required to characterize climate change impacts. However, there are limited
studies of permafrost and ground temperature in the Kivalliq region. We have conducted scientific planning and fieldwork in Rankin Inlet and over the Kivalliq region of Nunavut for providing permafrost information and understanding permafrost
conditions for this area. Recent fieldwork involved geomorphological observations, examination of surficial geological materials, and site selection for establishment of permafrost monitoring stations. Initial sites at Rankin Inlet and Ennadai Lake
were instrumented with ground temperature sensors. Additional site locations were chosen to represent a variety of conditions including developed and undeveloped land, and different geological settings. |
