- In areas with under 50 cm snow cover in winter, the permafrost zones can be defined by freezing indices and thawing indices. The relationship works for Norway, Spitsbergen, Canada and Mongolia, and since these include a very wide range of thermal
- environments, it is possible to trace the thermal ranges of the various active periglacial landforms. Relationships between zonal permafrost landforms and permafrost zones are emphasized.

- Winter ground surface temperature regimes in the zone of sporadic discontinuous permafrost, Tatra Mountains (Poland and Slovakia)
- Eastern Europe ; Europe ; Geophysics ; Mountain ; Periglacial features ; Permafrost ; Poland ; Slovak Republic ; Snow cover ; Soil temperature ; Spatial distribution ; Tatra Mountains
- Ground surface temperatures in the zone of sporadic discontinuous permafrost in the Tatra Mountains were monitored over 2 winters at sites where either permafrost or deep seasonal frost had been previously posited. The results show that contemporary
- permafrost can exist beneath both thick and thin snow covers. The AA. infer that its presence may relate more to local circulation of cold air over the surface and low summer solar irradiation than to elevation and snowpack development.
- Dissolved organic carbon fluxes in a discontinuous permafrost subarctic alpine catchment
- Interactions of permafrost with climatic, hydrologic and ecosystem processes. Special issue
- Active layer ; Canada ; Carbon ; Hydrology ; Meltwater ; Periglacial features ; Permafrost ; Runoff ; Water balance ; Watershed ; Yukon Territory
- The sources and fluxes of dissolved organic carbon (DOC) were investigated within a subarctic catchment with discontinuous permafrost (Granger Basin, Yukon) from 23 June 2001 to 22 June 2002. The A. studies the mechanism whereby DOC is flushed
- to the stream during spring freshet and summer rainfall events, evaluates what roles permafrost and frozen ground play in DOC flushing, and provides a first-order estimate of annual DOC export.
- Morphology and geotechnique of active-layer detachment failures in discontinuous and continuous permafrost, northern Canada
- Active layer ; Canada ; Ellesmere ; Geotechnics ; Landslide ; Northwest Territories ; Periglacial features ; Permafrost ; Slope dynamics
- Fifty active-layer detachment failures triggered after forest fire in the discontinuous permafrost zone (central Mackenzie Valley) are compared to several hundred others caused by summer meteorological triggers in continuous permafrost (Fosheim
- Peninsula, Ellesmere Island). Most failures fall into compact or elongated morphological categories. The location of the shear planes or zones in relation to the permafrost table and the degree of post-failure secondary movements (including headwall

- Frequency and magnitude of active-layer detachment failures in discontinuous and continuous permafrost, Northern Canada

- Active-layer detachment failures triggered weeks to months after forest fire in central Mackenzie Valley (65°N, discontinuous permafrost zone) are compared to others generated almost immediately by summer meteorological conditions on the Fosheim
- Peninsula, Ellesmere Island (80°N, continuous permafrost zone). The AA. focus here on the environmental triggers of detachment failure, frequency-magnitude relations, and discuss possible climate change impacts on initiation frequency.

- The extent of permafrost in 9 talus slopes located within the alpine periglacial belt in the western Swiss Alps was investigated using ground surface temperature measurements and one-dimensional geoelectrical profiles. The cooling of the ground

- Arctic Region ; Cold area ; Mountain ; Norway ; Pedogenesis ; Permafrost ; Soil ; Soil classification ; Soil temperature ; Sweden ; Taxonomy ; Thermal regime
- This paper is an attempt to draw attention to the field problems raised by Soil Taxonomy classification requirements in alpine environments where permafrost is discontinuous or sporadic. It also provides 2 simple illustrations of spatial ground
- temperature variability drawn from the Abisko Mountains of northwestern Sweden and the Jotunheimen Mountains of central Norway where ridge crests are probably underlain by permafrost, but valley bottoms are not, and valley flanks may contain discontinuous

- 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 permafrost zones in the southern half of the Yukon (60°N to 64

- Thermal state of permafrost in Russia
- Climatic warming ; Cold area ; Global change ; Periglacial features ; Permafrost ; Polar region ; Russia ; Soil temperature ; Thawing ; Thermal regime
- ground temperatures measured in existing and new boreholes show a substantial warming during the last 20 to 30 years. Thawing of permafrost is most noticeable within the discontinuous permafrost domain. However, permafrost in Russia is also starting
- to thaw at some limited locations in the continuous permafrost zone. As a result, a northward displacement of the boundary between continuous and discontinuous permafrost zones was observed.
- The results of the International Permafrost Association's International Polar Year Thermal State of Permafrost (TSP) project are presented based on field measurements from Russia during the IPY years (2007-09) and collected historical data. Most
