| Floating litter has serious ecological and socio-economic impacts and is recognized as assessment criteria under the EU Marine Strategy Framework Directive. Floating litter density is suspected to be very high in the Black Sea which is a semi-enclosed basin that received freshwater drainage from 21 countries. However, the available data are not yet sufficient to identify resources and accumulation areas of floating litter. To fill in this lack of data, floating macro litter (> 2.5 cm) survey was carried out between 16.10. 2019-19.10. 2019 as a part of the TÜBİTAK 118Y125 project “Distribution, composition, sources and ecological interactions of micro-and nanoplastics in Southeastern Black Sea”. Floating macro litter were visually counted, from the vessel in 30-60 minutes transects, by experienced observed following the marine litter monitoring methodology for European Seas of EU JRC. The amount and composition of floating litter observed in a total of 7 surveys, covering a total area of approximately 557452 m2, were determined.Concentrations of floating macro litter were found to be highly variable, ranging from ca. 45 items/km² to above 5093 items/km². Plastics constituted 98.8% of the total floating litter observed. The most common items were plastic pieces (hard, nylon and foam) followed by food packaging and plastic bags. Concentrations of floating macro litter in some areas were extremely high, which was possibly linked with land-based sources or retention zones associated to oceanographic features such as filaments and eddies. |
