Recent Advances in Permafrost Modelling
This paper provides a review of permafrost modelling advances, primarily since the 2003 permafrost conference in Zurich, Switzerland, with an emphasis on spatial permafrost models, in both arctic andExpand

The Thermal State of Permafrost in the Nordic Area during the International Polar Year 2007-2009
This paper provides a snapshot of the permafrost thermal state in the Nordic area obtained during the International Polar Year (IPY) 2007-2009. Several intensive research campaigns were undertakenExpand

Permafrost and climate in Europe: Monitoring and modelling thermal, geomorphological and geotechnical responses
We present a review of the changing state of European permafrost within a spatial zone that includes the continuous high latitude arctic permafrost of Svalbard and the discontinuous high altitudeExpand

The relative age of mountain permafrost — estimation of Holocene permafrost limits in Norway
Abstract For Scandinavia in general and Norway in particular the regional distribution of mountain permafrost is reasonably well known, both through ground temperature measurements in boreholes,Expand

Permafrost is warming at a global scale
Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon. Yet to date, no globally consistent assessment of permafrostExpand

Characteristics of Discontinuous Permafrost based on Ground Temperature Measurements and Electrical Resistivity Tomography, Southern Yukon, Canada
Warm permafrost conditions (mean temperatures of −3°C to −0.1°C) were investigated in detail at 13 valley and mountain sites in the sporadic (10–50%) and extensive (50–90%) discontinuous permafrostExpand

Relative surface age-dating of rock glacier systems near Hólar in Hjaltadalur, northern Iceland†
Schmidt-hammer rebound values and photogrammetric measurements of surface displacement were used to date two active polymorphic (high-altitude) and two relict monomorphic (low-altitude) rock glaciersExpand

Terrain parameters and remote sensing data in the analysis of permafrost distribution and periglacial processes: principles and examples from southern Norway
Alpine permafrost and frost-related geomorphological processes are sensitive to climatic change. Thus, there is an increasing demand for permafrost maps in high-alpine environments. The objective ofExpand

The assessment of potential geotechnical hazards associated with mountain permafrost in a warming global climate
European mountain permafrost is generally only a few degrees below zero Celsius, and may therefore be highly sensitive to climate change. Permafrost degradation may lead to thaw settlement andExpand

The regional distribution of mountain permafrost in Iceland
A regional map of permafrost distribution in Iceland was developed based on meteorological data. The regional model was calibrated with ground surface temperature data and tested using groundExpand
