Abstract

The study area is located near the Inuit community of Umiujaq and in the area around the mouth of the Nataspoka River on Hudson Bay. Images from tomodensitometric scanning (CT scan) on numerous permafrost cores from permafrost mounds and plateaus of various shapes were analysed. The results reveal that the ice layer sequences and permafrost internal structure vary with landform types. A relationship therefore exists between different morphological type within a family of landforms and their microscale internal structure
