Bottom trawling is a well-known global phenomenon and has significant physical impact on the seabed habitat, such as compression, displacement and mobilization of the sediment. Thus, it is necessary to examine how it alters the seabed, e.g., in order

Abstract A series of multibeam bathymetry surveys revealed the emergence of a large pockmark field in the southeastern North Sea. Covering an area of around 915 km2, up to 1,200 pockmarks per square kilometer have been identified. The time of emergen
