CRYOSLOPE - Monitoring, dating and modelling climate change effects on high arctic mountain slope processes and their impact on traffic ...

Tildelt: kr 2,9 mill.

CRYOSLOPE Svablard will study how cold mountain slopes in Svalbard will respond to future projected climatic changes and how these potential changes could affect the traffic on the roads in the Longyearbyen settlement and the surrounding highly used winte r roads connecting the settlements and tourist attractions in Nordenskiöld Land. The study will be a combination of systematic observations of slope processes, measurements of meteorological parameters on the slopes, as well as past geological and geomorp hological studies of slope process activity together with meteorological data available since 1912. We will study the 40 km most used summer and winter roads in three steep terrain areas in and around Longyearbyen, where avalanches occur every winter caus ing problems for the traffic. Effects of local climate features in the study area will be analysed by having meteorological observations from existing automatic weather stations made available on-line, and placing two masts with extra instruments in the s tudy area. Also, intensive campaigns with extra meteorological equipment will be performed. Different types of slopes (snow, soil or rock) will be studied using manual and automatic instrumentation both in the summer and in the winter in order to establis h a database with all slope events for improved understanding of the meteorological control on slope process activity. This GIS database will allow future potential testing of avalanche models for Svalbard, and combined analyses of meteorological and slop e landform activity data, enabling the preparation of scenarios of future slope landform activity during changed climatic conditions in the study sites. Another output from the project will be digital and printed landform maps for the study areas. These w ill be important in future modelling work.
