Summary

Abstract: For monitoring of permafrost temperature, this borehole was drilled in Adventdalen, in the the old, dry river channel from Todalen. The channel collects 2-3m of snow in winter. An automatic camera is used to monitor the snow cover. The borehole was drilled to 10m and instrumented to 5m. Stratigraphy: 0-2m: Till. Possibly silt and clay layers from 1.5m. Some ice 1-1.5m. Ice-rich 1.5-2m. 2-3.3m: Ice-rich (~50%) and silt/clay layers. A few thin coarser layers 3.3-4m: Coarser and less ice. 4-6m: Some ice (less with depth). Silt/clay layers in coarser (gravel) material. 6-10m: silt/sand/(clay). Increasing plasicity with depth.
