Abstract
- Anthropogenic marine litter (AML) is a global environmental concern. One of the most conspicuous effects of AML is beach litter accumulation, the distribution of which is typically heterogenous. Little information is available on the potential effects of coastal topographic features on litter dispersal. We analysed the abundance, composition, and sources of beach litter on the East coast of England in relation to the presence of coastal groyne structures. Six beaches were surveyed in autumn and winter 2021 using the OSPAR methodology for monitoring beach litter. Litter abundance was lower on beaches with groynes present, which could infer that groynes deflect or bury AML. The presence of groynes had no significant effect on the composition/sources of beach litter. Single-use plastic packaging, fishing waste, and sewage-related debris were the largest contributors of beach litter in this region. Our findings indicate that man-made topographic features may affect marine litter dispersal and coastal accumulation. • Coastal groynes trap sediment transported by longshore drift, increasing accretion. • Litter abundance was lower on beaches with groynes compared to those without. • Topographic features may affect marine litter dispersal and coastal accumulation. • Single-use plastic, fishing waste, and sewage debris were the largest contributors. • The findings will help inform implementation of litter mitigation strategies.
