A cobble beach (-60 to -80)located on the South Wales coastline, UK, was studied over a three-month winter period to assess litter input levels. After total beach litter clearance, six surveys were conducted at consecutive spring tides which involved marking of previously unrecorded litter. The beach was soon inundated with debris, predominantly plastic beverage containers. Some marked litter was found to disappear from the beach surface, reemerging weeks later which suggests that the potential for titter burial has been underestimated in litter research. Higher wave energies between surveys coincided with higher levels of previously unseen Utter. These new inputs consisted of sea borne and exhumed litter. Items larger than the surrounding cobbles were found to work their way back to the surface of the beach after burial, smaller items remained buried. Pits dug into the cobble ridge confirmed the burial of mainly small items. (C) 2001 Elsevier Science Ltd. All rights reserved.
