  Increased snow depth already observed, and that predicted for the future are of critical importance to many geophysical and biological processes as well as human activities. The future characteristics of sub-arctic landscapes where permafrost is particularly vulnerable will depend on complex interactions between snow cover, vegetation and permafrost. An experimental manipulation was, therefore, set up on a lowland peat plateau with permafrost, in…

• What Determines the Current Presence or Absence of Permafrost in the Torneträsk Region, a Sub-arctic Landscape in Northern Sweden

  In a warming climate, permafrost is likely to be significantly reduced and eventually disappear from the sub-Arctic region. This will affect people at a range of scales, from locally by slumping of buildings and roads, to globally as melting of permafrost will most likely increase the emissions of the powerful greenhouse gas methane, which will further enhance global warming. In order to predict future changes in permafrost, it is crucial to unde…

  Åkerman H. Jonas: Observations of paisas within the continuous permafrost zone in eastern Siberia and in Svalbard. Geografisk Tidsskrift 82: 45–51, Copenhagen, October 15, 1982. Observations from the area north of Chernychevsky, Yakutia, USSR (63° N 112°E) are described. In the area several paisa bogs of a »Nordic type«, containing well developed paisas of the dome, plateau and complex types, are found. In Svalbard four types of palsa-like featur…
