Abstract: Longyearbyen is situated in a mountainous landscape, thus infrastructure, living and travelling in and around Longyearbyen is highly affected by mountain slope processes. This mountain landscape undergoes changes during the whole year as a consequence of freezing and thawing, snow melting, erosion, rock fall or snow avalanches, mainly due to the high arctic climate. The CRYOSLOPE Svalbard project marks the first systematic attempt to observe these mountain slope processes and investigate how they affect traffic and infrastructure. A year round observation program observes mainly snow avalanches, their spatial occurrence and timing as well as meteorological and snow pack factors controlling the slope processes. Subsequently this data is related with the amount of snow mobile traffic directly affected in the valleys.
