Laser scanning of ice rubble (Isfjorden,Svalbard - 9 April 2020)

The ice rubble was observed at the beginning of April 2020 near Longyearbyen town, along the shore of Isfjorden, Spitsbergen. There was no such observation in the previous years and after. The rubble appeared after a storm that lasted for several days and left also piles of seaweed onshore 3-4 m above the water level, revealing the wave height. Laser scanning session (in different tidal phase) was performed 9 April 2020 to estimate the size of the rubble and ice block composition. The main ice rubble had size 250x500m with the sail height of ice blocks up to 6 m above water level. Ice floes constructing the rubble were up to 0.9 m thick.
