Thermal regime of ice‐wedge cracking in Adventdalen, Svalbard
Abstract 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 o...
