Anthropogenic marine debris (AMD) is frequently studied on sandy beaches and occasionally in coastal waters, but links between these two environments have rarely been studied. High densities of AMD were found in coastal waters and on local shores of a large bay system in northern-central Chile. No seasonal pattern in AMD densities was found, but there was a trend of increasing densities over the entire study period. While plastics and Styrofoam were the most common types of AMD both on shores and in coastal waters, AMD composition differed slightly between the two environments. The results suggest that AMD from coastal waters are deposited on local shores, which over time accumulate all types of AMD. The types and the very low percentages of AMD with epibionts point to mostly local sources. Based on these results, it can be concluded that a reduction of AMD will require local solutions.
人为海洋垃圾（AMD）经常在沙滩上进行研究，偶尔也在沿海水域进行研究，但这两个环境之间的联系很少被研究。在智利中北部的一个大型海湾系统的沿海水域和当地海岸发现了高密度的 AMD。AMD 密度没有发现季节性模式，但在整个研究期间存在密度增加的趋势。虽然塑料和泡沫聚苯乙烯在海岸和沿海水域都是最常见的 AMD 类型，但这两个环境中的 AMD 组成略有不同。结果表明，来自沿海水域的 AMD 沉积在当地海岸上，随着时间的推移，这些 AMD 会不断积累。AMD 类型和带有附生物的 AMD 的极低比例表明主要来自本地。基于这些结果，可以得出结论，减少 AMD 需要采取当地的解决方案。
