Coastal plastic pollution is a global problem, it affects local ecosystems, and can have economic and social implications. Plastic pollution is pervasive at high latitudes but there is a lack of data on the spatial and temporal amount of marine litter entering coastal systems. In this study, a seasonal accumulation survey of anthropogenic debris and beach wrack was conducted for the first time in Iceland. One hundred data collections were performed on a coast in the Snæfellsnes peninsula throughout one year. Of all the debris retrieved, over 9000 items (0.2 to 50 cm), 78.5 % were plastics. Beach wrack correlated strongly with the quantities of plastic debris entering the coastal environment (R > 0.9; p < 10), with a different slope for each season. The presence of beach wrack informed important daily and spatial fluctuations in the quantities of plastic debris, while seasonal fluctuations demonstrated higher arrival rate of plastic in autumn and winter.
沿海塑料污染是一个全球性问题，它影响着当地的生态系统，并可能带来经济和社会方面的影响。高纬度地区的塑料污染非常普遍，但有关进入沿海系统的海洋垃圾的时空数量的数据却很缺乏。在这项研究中，冰岛首次对人为碎片和海滩漂木进行了季节性积累调查。在一年的时间里，在斯奈菲尔半岛的一个海岸上进行了一百次数据收集。在所回收的所有碎片中，超过 9000 件（0.2 至 50 厘米），78.5%是塑料。海滩漂木与进入沿海环境的塑料碎片数量密切相关（R > 0.9；p < 10），每个季节的斜率都不同。海滩漂木的存在使塑料碎片的数量呈现出重要的日常和空间波动，而季节性波动则表明秋季和冬季塑料的到达率更高。
