This data set contains quality controlled soil temperature and volumetric liquid water content measurements from a site at the forest-tundra transition in the western Canadian Arctic. The measurement site is near by the Trail Valley Creek (TVC) research station, which is operated by Wilfried Laurier University. The station is located east of the Mackenzie Delta and 45 km north of Inuvik. The published data set provides long-term observations on the thermal and hydrological state of the active layer at a hummocky tundra site within the continuous permafrost zone. The station consists of a soil depth-profile with four sensor sets at 2 cm, 5 cm, 10 cm, and 20 cm of paired soil moisture and soil temperature sensors. Additionally, three distributed soil moisture sensors are installed in the surface soil. The data series is continued since 2016 and provides a basis for process understanding and modelling studies of Arctic permafrost. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.983873"! ** Locations are: (a) next to horizontal profile at the hummock, (b) midway between hummock and shrub, and (c) in shrub water pathway.
