Abstract

Our research group jointly with the research group of Professor Motoyuki Sato, CNEAS (Tohoku University), conducted GPR survey in forested and forestless lands in Yakutia in August 12 - 15 1999. The aim of this survey was to test for the first time our GPR equipment on permafrost, to determine spatial dynamics of permafrost bedding depth in forested and forestless areas and to detect ice wedges in permafrost. The survey was carried out on the site about 30 km north-east of Yakutsk city. Numerous boreholes drilled in both forested and forestless areas determined permafrost bedding depth and showed that in forested areas permafrost in several spots had ice wedges more than half meter across. Measurements were made in the forest; on 'alas' (thermokarst depression) site; on the site of recent forest fire; on large forestless area with 'pingos' (round hills in 'alas' center). An attempt was made to detect 'pingo' ice kernel.
