Abstract
In connection with a road construction project between the towns of Sisimiut and Kangerlussuaq in Central
West Greenland, the Arctic Technology Centre has been involved in prospecting and site investigations. This
paper presents a selection of results concerning the climatic conditions and permafrost distribution, as well
as engineering geological and geotechnical investigations conducted. We present data from two soil
temperature stations, and show that the recent climatic warming has resulted in changes in the state of the
permafrost. Furthermore, we present a geological type section based on engineering geological
investigations in the Sisimiut area. Geophysical investigations show that presence of permafrost is
widespread, and our results indicate that the vertical thickness of the permafrost may reach 20 m. Further
climate warming in the near future will impose high demands on design and construction work in order to
counter the effects of permafrost degradation and increased active layer thickness.
