Zusammenfassung: | 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/ km2. 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.
•Usage of oceanographical information is very important for analyzing macro litter distribution•In the Eurasian Arctic Seas floating macro litter and natural objects have been found only in the Atlantic origin water•In the autumn period the river discharge is free from floating macro litter•The found floating macro litter concentrations averaged at 0.92 items/km2 (mean) with a maximum of 7.97 items/km2 |
