Marine litter abundance and composition on Chilean 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 Chilean beaches every four years from 2008 to 2020, as well as 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 zone and region 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.

本数据集由公民科学项目生成，收录了2008年至2020年每四年一次以及2021年智利海滩的垃圾调查数据，涵盖该时段内海滩上记录的主要垃圾物品丰度信息。具体而言，数据集包含在受访海滩布设的3m×3m采样站位中统计得到的大型垃圾（macrolitter，粒径>2.5cm）的物品数量，并按纸张、塑料、烟蒂等不同材质类别进行分组。此外，数据集还包含采样日期、受访海滩的名称与坐标、海滩所属的分区与行政区域、邻近各海滩的沿海城市或城镇名称、负责开展每次采样的学校或志愿者团体类型、每个采样站位内人为垃圾的总数量，以及每平方米的平均丰度。
