Litter has been found in all marine environments and is accumulating in seabirds and mammals in the Nordic Seas. These ecosystems are under pressure from climatic change and fisheries while the human population is small. The marine landscapes in the area range from shallow fishing banks to deep-sea canyons. We present density, distribution and composition of litter from the first large-scale mapping of sea bed litter in arctic and subarctic waters. Litter was registered from 1778 video transects, of which 27% contained litter. The background density of litter in the Barents Sea and Norwegian Sea is 202 and 279 items/km respectively, and highest densities were found close to coast and in canyons. Most of the litter originated from the fishing industry and plastic was the second most common litter. Background levels were comparable to European records and areas with most littering had higher densities than in Europe.
在所有海洋环境中都发现了垃圾，并在北欧海域的海鸟和哺乳动物中积累。这些生态系统正承受着气候变化和渔业的压力，而人口却很少。该地区的海洋景观从浅海捕鱼场到深海峡谷不等。我们首次对北极和亚北极水域海底垃圾进行了大规模测绘，展示了垃圾的密度、分布和组成。从 1778 个视频横切线上记录到垃圾，其中 27%含有垃圾。巴伦支海和挪威海的垃圾背景密度分别为 202 个/公里和 279 个/公里，最高密度出现在近岸和峡谷附近。大多数垃圾来自渔业，其次是最常见的塑料垃圾。背景水平与欧洲的记录相当，垃圾最多的地区的密度高于欧洲。
