Abstract:
This dataset reports cryostratigraphic information from three permafrost cores collected on 10–11 July 2024 within the Cambridge Bay watershed, Nunavut, Canada. Each core was sampled at successive depth intervals to document sediment texture, volumetric ice content, and visible stratigraphic structures. Field metadata include core coordinates, sampling date, and total core length. These observations provide detailed subsurface properties essential for assessing permafrost conditions and understanding sediment and ice configurations influencing erosion processes in High-Arctic terrain.
