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.

我们的研究提供了第一个关于在撒丁岛北部（意大利）的五个袖珍海滩收集的海洋垃圾的数据集。监测方法参考联合国环境署描述的海滩废物快速海滩评估操作指南。我们将收集到的 7975 个项目按照 8 个类别和 99 个类型进行分类。他们的分析表明，塑料是最常见的垃圾类别，而塑料碎片是最常见的垃圾。密度范围从0.05到2.82 item/m ². 前 10 名高度存在的海洋垃圾表明，陆上垃圾是主要来源，这可能是由于缺乏废物管理、大规模的旅游和娱乐活动。此外，景观形态影响海洋垃圾的重新分布。总体而言，这些初步结果是对撒丁岛北部袖珍海滩中海洋垃圾存在的更广泛研究的一部分，旨在为沿海管理者和决策者提供缓解策略。
