Data for: Legacy community science data suggest reduced beached litter in response to a container deposit scheme at a local scale

Marine debris is causing significant environmental harm. Legislation is being implemented to reduce litter, including schemes like container deposit legislation that incentivize the return of commonly littered items for recycling. While there is a suggestion that these schemes reduce litter, no study has examined the long-term impact on the local environment before and after implementation. This study analyzes community science data from 8 years prior to the implementation of a container deposit scheme, paired with 3 years of data afterwards, to assess the scheme's effectiveness at a local scale. Although using legacy datasets limits the generalizability of the conclusions compared to dedicated studies, the findings strongly indicate that container deposit schemes effectively manage targeted containers but have little impact on overall waste abundances. Long-term datasets like these are invaluable for assessing the impact of management efforts., , , # Legacy community science data suggest reduced beached litter in response to a container deposit scheme at a local scale

## Description of the data and file structure

There are two sets of analyses in this data bundle.
First, wind and current roses for data in the Whitsunday region.
The code \"Roses\_R1.R\" relies on the function \"WindRose\_f.R\"
\"Roses\_R1.R\" is the script used to create wind and current roses for Figure 1 in the manuscript.
The input files for these are available in the zip file \"dataFilesForRoses.zip\"
In that zip folder are:
\"BowenAirport\_wind.tx...

海洋垃圾（marine debris）正造成严重的环境危害。当前各国正推行各类立法以减少陆地垃圾排放，其中包括容器押金立法（container deposit legislation）这类通过激励民众返还常见乱丢物品以进行回收的方案。尽管有观点认为这类方案可有效减少垃圾乱丢的情况，但目前尚无研究考察该类方案实施前后对当地环境产生的长期影响。本研究利用容器押金方案实施前8年与实施后3年的公民科学（community science）数据，旨在评估该方案在地方尺度上的实施成效。尽管与专门设计的研究相比，使用遗留数据集（legacy dataset）会限制研究结论的推广性，但本研究结果清晰表明，容器押金方案可有效管控目标容器类垃圾，但对整体垃圾丰度几乎无影响。此类长期遗留数据集对于评估管理措施的实施效果具有不可替代的价值。
