Measurement of active layer thickness at 300 points has been carried out. Active layer thickness was determined with soundings and measurements using the Danilin frostmeter. A series of soundings has been made each summer within geo-complexes with different water conditions, vegetation and aspect. The characteristics of the active layer are based on data from representative stands in which observations of thermal conditions of the ground were taken.

Data include maximum and minimum air temperatures at 5 and 200 cm, and ground temperature at 5 cm. These data are from the IPA's Circumpolar Active Layer Monitoring (CALM) Program site P1 at Calypsostranda, Recherche Fjord, Wedel Jarlsberg Land, Svalbard, at 77o 34' N; 14o 30' E. Observation/Instrumentation (depths): maximum probe values reported from a series of plots; some measurements with the Danilin frostmeter; shallow soil temperature data available Site history: data since 1986. Data on CAPS Version 1.0 CD-ROM are from 1986-1993.
