  • Patterns in vegetation composition, surface height and thaw depth in polygon mires in the Yakutian Arctic (NE Siberia) : a microtopographical characterisation of the active layer
  • in thaw depths and strong correlation with relief, water and vegetation. Average thaw depths in polygon ridges (23 cm and 31 cm) were smaller than in depressions (33 cm and 40 cm, respectively). The greatest thaw depths, however, were also found

  • temperatures and exhibits seasonal freeze-thaw, whereas the other aspects show frequent diurnal freeze-thaw. These differences result in seasonal rockfall activity on the north-facing slope and the infrequent release of large debris and year-round rockfall

  • distribution of permafrost and boundaries of the permafrost zones. The methodological approach is presented. Calculations of mean annual surface temperatures and of thawing and freezing indices led to the development of regional maps, in this case for northern
  • and the early 2000s, results and discussion about the correlation between surface movement, snow thickness and ground sub-surface temperatures. Finally, unusual surface lowering that accompanied peak velocities in 2004 may be due to a general thaw of the top
