Sediment Compaction below Iceberg Furrows

Souring of the seabed by icebergs and ice keels is a phenomenon unique to the cold oceans. The threat to buried offshore structures and installations from such a process is obvious. Laboratory experiments and field observations show that the sediment outside the actual scour is also subjected to some degree of movement, compression and compaction. This paper describes the experiments in the laboratory and the analysis of the pressures measured on a pipeline model buried at different depths below the gouge bottom.
