ICE GOUGINGIN THE KARA SEA, RECORDED BY MEANSOF SIDE SCAN SONAR
One of the Arctic underwater construction (product pipelines, cables, etc.) hazards are icebergs that "plow" the shallow water bottom by its underwater part, moving under the influence of surface waves and wind. This phenomenon is also a threat to underwater disposal of radioactive waste in the bays of Novaya Zemlya. Their coastal environment includes glaciers des-cending from the central part of the archipelago. Furrows in the bottom left by icebergs are well recorded with the help of side scan sonar. The report shows bathymetry and iceberg tracks sonar images. Risk rate of this phenomenon is discussed.
