  • Statistical analyses of active patterned ground occurrence in the Taillon Massif (Pyrénées, France/Spain)
  • Factor analysis ; France ; Mountain ; Multivariate analysis ; Patterned ground ; Periglacial features ; Pyrénées ; Sampling ; Spatial analysis ; Statistics
  • A novel spatial sampling strategy focusing only on fields with potential patterned ground occurrence was used. The data were examined using factor analyses (multiple correspondence analysis and hierarchical ascendant classification) blended
  • with a complementary bivariate method to associate patterned ground occurrence with 8 environmental variables. The absence of active patterned ground is associated with low elevation, glacier absence, no slopewash, a low height-distance ratio and talus fans. Zones
  • where active patterned ground features are present are divided into 3 homogeneous subzones and are mostly associated with glacier influence, a large height-distance ratio and an absence of vegetation. Their location is controlled by the presence of till
  • from different glacial sequences so that the former and current presence of glaciers favours the development of patterned ground features at the landscape scale.

  • The A. explains his work as an exercise in contemporary history drawn from press reports, interviews with people on the ground and accounts of exiles living outside of Burma since the tumultuous events of 1988. Themes connecting the past
  • with contemporary developments, like the centrality of Buddhism and its holy sites with the social, political and spiritual life of Rangoon, are emphasized. The past is always remembered and close by. Certain patterns seem to recur in the former capital : state

  • The Mars Global Digital Dune Database (MGD3) now extends from 90°N to 65°S. The database, available in GIS- and tabular-format in USGS Open-File Reports, makes it possible to examine global dune distribution patterns and to compare dunes with other
  • as ground truth for atmospheric models is reviewed. Comparisons between dune-derived winds and global and mesoscale atmospheric models suggest that local topography may have an important influence on dune-forming winds. Third, the methods used here

  • Field sampling of tabular ground ice (TGI) was undertaken at a number of geological sections along the Russian Arctic coast. S 34 in sulfate ion and C 13 in organic matter were analysed in ground ice and enclosing deposits, and in reference samples

  • Ground thermal conditions at Chachani volcano, Southern Peru
  • This article analyses temperature variations around 0°C in shallow ground and the elevational distribution of annual average air temperatures, to determine elevational boundaries for periglacial and permafrost environments in the Chachani volcanic
  • complex in the west-central Andes in southern Peru. Three stations were installed at 4850, 4976 and 5331 m a.s.l. on the southern slope and the data were processed to produce ground temperature distribution models at depth and altitude.

  • °N), using a combination of ground temperature monitoring, electrical resistivity tomography (ERT), frost table probing and coring. Sites were selected to cover a wide range of substrates, vegetation types and ground ice contents. ERT profiling
  • in the spring imaged both deep seasonal frost and perennially frozen ground. The observations revealed the complexity of site conditions where permafrost is discontinuous and the utility of ERT, in combination with other methods, to investigate permafrost

  • Air and ground temperature variations observed along elevation and continentality gradients in southern Norway
  • The coupling between air and ground temperatures in the mountains of southern Norway was examined using 12 shallow boreholes drilled in August 2008. Three borehole arrays (at Juvvass, Jetta and Tron), each with boreholes at different elevations
  • , were established along a continentality gradient. Here, the AA. present the first two years of air and ground temperature measurements and discuss the influences of air temperatures, ground surface characteristics (snow conditions, sediments/bedrock
  • , vegetation) and topographic parameters on the ground thermal regime.

  • This paper reviews isotopic research on the characterisation and identification of various types of ground ice throughout the Canadian Arctic, including buried glacier ice, massive segregated ice, segregated ice lenses and offshore ice-rich
  • permafrost, as well as ice related to other cold-region phenomena such as ice wedges, icings (aufeis), frost blisters and pingos. The formational age of ground ice bodies ranges from recent (seasonal ice in the active layer) to tens of thousands of years

  • Herschel Island in the southern Beaufort Sea is a push moraine at the northwestern-most limit of the Laurentide Ice Sheet. Stable water isotope (δ18 O, δD) and hydrochemical studies were applied to two tabular massive ground ice bodies to unravel
  • their genetic origin. Buried glacier ice or basal regelation ice was encountered beneath an ice-rich diamicton with strong glaciotectonic deformation structures. Both massive ground ice bodies exhibited a mixed ion composition suggestive of terrestrial waters

  • Shallow ground temperatures and periglacial processes on Iztaccíhuatl volcano, Mexico
  • Air and ground temperatures were measured at 5 sites from 4137 m to 5020 m asl on the southwest slope of the volcano between 2001 and 2007. Snow lies on the ground for only a few days each year and has almost no effect on periglacial process
  • distribution. Daily freeze-thaw cycles at the ground surface are numerous at the summit (around 212 days annually), but cycles cease only a few centimetres below the surface, so that frost action does not occur below 60 cm depth. Permafrost is present at 4900 m

  • Effect of ground cover on splash and sheetwash erosion over a steep forested hillslope : a plot-scale study
  • The contributions and relationships of erosion by splash and overland flow over a steep slope in a Japanese beech forest in plots with different percentages of ground cover were examined. Three erosion plots with average understory coverage of 1
  • %, 45%, and 94% were installed. Sediment transported by rain splash and by overland flow was sampled separately. The sparse ground cover showed the largest variation of splash and sheetwash contribution in soil erosion. This variability was due
  • to variation in ground cover and soil surface wetness condition which led to a variation of detachment and non-linear relationship of sheetwash splash.
