Our study provides a first dataset on marine litter collected at five pocket beaches situated in the northern Sardinia (Italy). The monitoring method refers to the operational guidelines for rapid beach assessment of beach waste described by UNEP. We classified the 7975 items collected according to the eight categories and 99 types. Their analysis indicates that plastic is the most common litter category and, plastic fragments are the most frequent debris. The density ranges from 0.05 to 2.82 item/m2. The top 10 highly present marine litter reveals that land-based litter is the main source, probably due to the lack of waste management, massive tourism and recreational activities. In addition, landscape morphology affects the redistribution of marine litter. Overall, these first results are part of a wider study on the presence of marine litter in the pocket beaches of north Sardinia to provide coastal managers and policy makers mitigation strategies.
