The main objectives of this work were the acquisition of new data on floating marine macro litter (FMML) and natural floating objects in the Arctic seas, an initial assessment of the level of pollution by FMML and an analysis of potential sources. The results of this study present the first data on FMML distribution in Russian Arctic shelf seas in relation to oceanographic conditions (i.e. position of water masses of different origin as described by temperature, salinity, dissolved oxygen and pH). The main finding of this study is that FMML was found only in the water of Atlantic origin, inflowing from the Barents Sea, where FMML average density on the observed transects was 0.92 items/ km. Eastern parts of the study, Kara Sea, Laptev Sea and East Siberian Sea were practically free from FMML. No input from rivers was detected, at least in autumn, when the observations were performed.
本工作的主要目的是获取关于北极海域浮动海洋大型垃圾（FMML）和天然漂浮物的新数据，初步评估 FMML 的污染水平并分析潜在来源。本研究的结果首次提供了与海洋学条件（即不同来源的水团的位置，如温度、盐度、溶解氧和 pH 所描述的）有关的俄罗斯北极陆架海域 FMML 分布的数据。本研究的主要发现是，仅在巴伦支海流入的大西洋水团中发现了 FMML，在观测横截线上的平均密度为 0.92 个/公里。研究的东部地区，即喀拉海、拉普捷夫海和东西伯利亚海实际上没有 FMML。至少在秋季进行观测时，没有发现来自河流的输入。
