Greater North Sea Ecoregion

Pressure: Abrasion

​​​​​​​​​​​Using vessel monitoring system (VMS) and logbook data it has been estimated that mobile bottom trawling techniques used by commercial fisheries in the 12 m+ vessel category have been deployed over approximately 290 000 km2 of the Greater North Sea in 2013, corresponding to ca. 42.5% of the ecoregion’s spatial extent. The proportion of swept seafloor decreased gradually by ca. 7.5% between 2009 and 2013.​​
