(Phys.org) —FOM researchers have discovered that objects floating on surface waves behave differently than expected. If a small number of floating objects is present on a water surface, these will drift to the locations where waves peak. However, a large number of floating objects will gather where the water is stationary. This finding might lead to new, efficient methods for cleaning up litter from the sea. The study was published on 13 May 2014 in Physical Review E.
