Childs Scribble

Spain

The suction marks from dredging the seafloor look like the random scribble of a small child using a pen and paper for the first time. Sedimentary material dredges from different harbors are necessary to maintenance to the depth of the shipping channels and also for the extraction of material due to construction purposes. Each suction track is 10 m wide and 30 cm deep and shows the random navigation by the vessel to remove the material.
