Quantification of sediment transport into Kongsfjorden due to the glacier melt dynamics of Austre Lovenbreen using terrestrial laser scanning

International audience; Climate warming causes a decrease of glaciers in Svalbard. This results in sig-nificant changes of the geomorphology of areas in glacier catchments where iceand permafrost is melting. In particular the snout of the glacier melts drasticallyand the water outflow of the glacier changes sometimes its direction. Sedimentand bed load transport forms new river beds in the moraine, and the sedimentsinvolved are transported downstream into the fjords. In recent years terrestriallaser scanning technology has developed significantly, so it is possible to mea-sure the surface of a whole glacier catchment such as the Austre Lovenbreen inhigh resolution just in a few days or even…

Landslide monitoring using multi-temporal terrestrial laser scanning(TLS) and electrical resistivity tomography (ERT) in the high Arctic,Ny-Ålesund

International audience; The acceleration of climate-induced changes in high arctic environments is evident and lead to a wide range ofprocesses (e.g. glacier retreat, landslide activity). Recent studies (Bernard et al. 2014) provide evidence that, thestability of the talus covered slopes is reducing and thus landslides are occurring more frequently on the slopessurrounding the Austre Lovénbreen glacier.The Austre Lovénbreen glacier basin is a relatively small arctic glacier basin located at 79◦N, Ny-Ålesund(Svalbard) and geologically is part of the Kongsvegen Group, which is composed of the Nielsenfjellet, Steenfjelletand the Bogegga Formation. This study focusses on the quantitative and sp…

Snow studies in the Austre Lovén glacier basin, Kongsfjorden, Svalbard

Landslide characterisation based on multi-temporal terrestrial laser scanning in the cirque of the Austre Lovénbreen

International audience; The slopes surrounding the Austre Lovénbreen glacier (79 • N, Ny-Alesund, Svalbard) were selected to study the occurrence, spatial distribution and temporal evolution of landslide processes in the high arctic. In addition, the impact of ongoing glacier retreat and warming-induced permafrost degradation on landslide formation mechanisms is investigated by analyses of multi-temporal terrestrial laser scanning (TLS) data and geological field surveys. The cirque of Austre Lovénbreen glacier is located in the basement rocks of the Kongsvegen Group which is composed of the Nielsenfjellet, Steenfjellet and the Bogegga Formation. For this study particular focus is placed on …
