The stability of permafrost soils is highly affected by the prevailing thermal regime. With warming ground temperatures and deepening of the active layer, thaw consolidation and associated ground subsidence are likely to occur. This is also expected for the surroundings of Ny-Ålesund, Svalbard.
In this project, the applicant will investigate the thermal regime in this area with a focus on thaw consolidation and ground subsidence. Background temperature data is provided by the University of Oslo, while DGPS surveys, documentation of soil profiles and soil sampling will be performed during field season 2022.
