Marine litter abundance and composition on Pacific Latin American beaches, registered by the Científicos de la Basura citizen science program

Data set generated by means of citizen science, which contains the abundances of the principal litter items registered on beaches along the Pacific coast of Latin America in 2021. Specifically, the data set contains the numbers of macrolitter items (> 2.5 cm) counted within 3m x 3m sampling stations positioned within the surveyed beaches, grouped according to different material categories (such as papers, plastics, cigarette butts, among others). The data set also contains the sampling dates, the names and coordinates of the surveyed beaches, the country where they are located, the nearest coastal city or town to each beach, the name of the school or the type of volunteers group that conducted each sampling, the total sum of anthropogenic litter items within each sampling station, and the mean abundance per square meter.

本数据集依托公民科学项目生成，收录了2021年拉丁美洲太平洋沿岸海滩上记录的主要海洋垃圾组分丰度数据。具体而言，数据集涵盖受访海滩内布设的3米×3米采样站点中统计得到的大型垃圾（粒径＞2.5厘米）数量，并按纸张、塑料、烟头等不同材料类别进行分组统计。此外，数据集还包含采样日期、受访海滩的名称与坐标、所属国家、各海滩邻近的沿海城镇名称、负责开展各次采样工作的学校或志愿者团队类型、每个采样站点内人为源垃圾的总数量，以及每平方米的平均垃圾丰度。
