| dc.description.abstract | During late July and the beginning of August 2010 a field study on slope processes was developed in Linnédalen, central Spitsbergen (figure 1). The aim of this project is to analyze slope processes in the region focusing primarily on snow avalanching as a function of sedimentation. The study will combine and correlate meteorological data, time-lapse camera imagery and prior studies in the area. The objective is to gain an understanding of the valley wall sedimentation and the significance of snow avalanching as a means of clast transport in Linnédalen. A focused study will be conducted on the eastern and western flanks of Griegaksla with a comparative analysis of slope characteristics with regards to rock type, grain size and slope features. The study also involves mapping the clast size distribution of five talus cones in the Linné valley using Arc GIS. Avalanche activity will be determined through time lapse photo imagery and Tinytag shock logger activity. Avalanche periods will also be compared to meteorological data. Twelve natural sediment traps are monitored between the eastern and western flanks of Griegaksla indicating yearly sedimentation. This study focuses on whether snow avalanching the predominant mechanism in the regional sedimentation, and what factors control sedimentation. The project will also try to hypothesize how slope processes evolved through time and what will happen in the future. | en_US |
