Abstract
This report summarises the output of the international workshop on in-depth analyses
of beach litter collected in 2022 from different Danish and Swedish sites in the
Skagerrak subregion. Skagerrak generally receives large amounts of litter, primarily
from local land-based and maritime sources as well as transboundary transport via ocean currents entering from the Greater North Sea. The assessment of the
geographical origin of mainly labelled litter items representing different types of
packing materials showed that about 1/3 originated from Nordic countries, 1/3 from other North Sea countries and the remaining 1/3 from countries outside the North Sea. An age assessment of these items showed that most were from recent years. Regarding the analyses of fishery-related litter items, it was assessed that a relatively large proportion could be assigned to discarded and mismanaged waste from net cuttings. However, also several other types of fishery-related litter were recorded. Methods for improving source identification and allocation of beach litter using the so-called matrix scoring techniques were also explored at the workshop.
