Preconditioning of mountain permafrost towards degradation detected by electrical resistivity
Warming permafrost has been detected worldwide and is projected to continue during the next century by many modelling studies. In mountain regions, this can lead to potentially hazardous impacts on short time-scales by an increased tendency for slope instabilities. However, time scales of permafrost thaw and the role of the ice content are less clear, especially in heterogeneous mountain terrain, where ice content can vary between zero and supers…
Year Permafrost Evolution Documented Through Petrophysical Joint Inversion, Thermal and Soil Moisture Data
This study investigates the ground characteristics of the high altitude (3410 m a.s.l.) permafrost site Stockhorn in the Swiss Alps using a combination of surface and subsurface temperature, soil moisture, electrical resistivity and P-wave velocity time series data including a novel approach to explicitly quantify changes in ground ice content. This study was motivated by the clear signal of permafrost degradation visible in the full dataset at t…

Twenty years of European mountain permafrost dynamics—the Pace legacy
This paper reviews and analyses the past 20 years of change and variability of European mountain permafrost in response to climate change based on time series of ground temperatures along a south-north transect of deep boreholes from Sierra Nevada in Spain (37 N) to Svalbard (78 N), established between 1998 and 2000 during the EU-funded PACE (Permafrost and Climate in Europe) project. In Sierra Nevada (at the Veleta Peak), no permafrost is encoun…
Ground temperature variations in a talus slope influenced by permafrost
Variations in surface and near-surface ground temperatures (GST) dominate the evolution of the ground thermal regime over time and represent the upper boundary condition for the subsurface. Focusing on the Lapires talus slope in the south-western part of the Swiss Alps, which partly contains massive ground ice, and using a joint observational and modelling approach, this study compares and combines observed and simulated GST in the proximity of a…
A spatial and temporal analysis of different periglacial materials by using geoelectrical, seismic and borehole temperature data at Murtèl–Corvatsch, Upper Engadin, Swiss Alps
Different geophysical investigations, such as electrical resistivity tomography (ERT) and refraction seismic tomography (RST), allow for an improved characterization of subsurface conditions in mountain permafrost areas. The knowledge of the permafrost internal composition constitutes a major prerequisite for climate-related modelling studies, for detailed hazard or local infrastructure assessments. To detect the small-scale variations of permafr…
Permafrost model sensitivity to seasonal climatic changes and extreme events in mountainous regions
Climate models project considerable ranges and uncertainties in future climatic changes. To assess the potential impacts of climatic changes on mountain permafrost within these ranges of uncertainty, this study presents a sensitivity analysis using a permafrost process model combined with climate input based on delta-change approaches. Delta values comprise a multitude of coupled air temperature and precipitation changes to analyse long-term, sea…
The potential of new measurement and modelling techniques in alpine cryosphere and geomorphology research
Die Hochgebirgs-Kryosphäre, insbesondere Schnee, Permafrost und Gletscher, spielt in Bezug auf die Auswirkungen eines sich ändernden Klimas auf die Gebirgsökosysteme eine Schlüsselrolle aufgrund (i) ihrer starken Sensitivität infolge von Temperaturen nahe dem Schmelzpunkt, (ii) ihrer Funktion als (Haupt-) Steuerungsgrösse des hydrologischen Abflusses und (iii) des Einflusses von Veränderungen bezüglich der saisonalen Schneedecke, da diese Boden-A…
