Anders, K., Antonova, S., Beck, I., Boike, J., Höfle, B., Langer, M., Marsh, P., Marx, S., (2018): Multisensor ground-based measurements of the permafrost thaw subsidence in the Trail Valley Creek, NWT, Canada, 2015-2016.

The study area of Trail Valley Creek (68° 44′ 17″ N 133° 26′ 5 26″ W) is located between Inuvik and Tuktoyaktuk, far north of the Polar circle. The field camp is operated by the teams of Philip Marsh and Jennifer Baltzer (Wilfried Laurier University, Canada). Several members of the 3DGeo Research Group and the Periglacial Research Section of the Alfred Wegener Institute joined the PermaSAR field campaigns in June 2015, August 2015, and August 2016 to establish this powerful geo-dataset.
During each of the three field campaigns ground-based data were acquired for two test sites by terrestrial laser scanning and GNSS. Furthermore, active layer thickness and thaw subsidence were measured manually at fixed benchmarks within the sites.
