  • For this period, the total number of identified published research papers was 72. Topics relating to ice wedges, thermokarst, palsas and patterned ground were characterised by high publication activity. Current trends suggest 3 main research thrusts

  • Glacially deformed permafrost at North Head, in the Tuktoyaktuk Coastlands, contains a complex ground-ice stratigraphy that formed during the course of the last glacial-interglacial cycle. Two generations of ground ice are distinguished within
  • a single stratigraphic sequence. The superimposition of post-deformation intrusive ice and massive segregated intrusive ice into permafrost containing pre-deformation ground ice indicates that substantial quantitites of overpressurized water were injected
  • One year of monitoring (2002-2003) at a low-centred ice-wedge polygon site on Svalbard is described. Ground temperatures were recorded hourly from the top of an ice wedge through the active layer to the ground surface in the central part of a trough
  • and in the adjacent rampart. Daily data on snow-cover depth were collected by automatic digital photography. Cracks were mapped in February, April and July. The results show that cracking occurred after ground temperatures at the centre of the ice-wedge top decreased
  • to below -15°c. Ground cooling in mid-winter occurred mainly through the snow-free ramparts because the ice-wedge troughs were filled by snow to depths of up to 30 cm.
