Were there any circumstances that influenced the survey?
A lot of litter had during the winter washed farther up the beach. This debris was not counted, but roughly estimated it was about the same amount of litter as it was on the beach. Amongst the finds where a big lump that may be similar to the clumps that washed ashore in the Koster area.
Were there any events that lead to unusual types and/or amounts of litter?
