BfN: Sand and gravel extraction

There are two main methods of extracting sand and gravel: In stationary extraction, an anchored cutter suction dredger excavates huge pits in the sea floor with depths of normally about 10 m and diameters of between 10 and 50 m. In the second method, a trailing suction hopper dredger removes sediment from the surface of the sea floor.
