The abundance and characteristics of benthic marine litter in the southern Black Sea shelf were demonstrated. During the surveys, 671 litter items weighing 83.93 kg were collected from the stations. The average density by number and weight were 460.70 ± 99.71 n/km2 and 80.68 ± 48.06 kg/km2. The litter density was significantly higher at 10-20 m (646.09 ± 165.63 n/km2) compared to 20-30 m (165.53 ± 81.02 n/km2) and >30 m (413.87 ± 146.59 n/km2) depth classes. Plastic (69.03%) was the most abundant material by number, followed by textile (20.94%) and metal (5.68%). The litter composition differed between the no-trawl zone and trawl ground. Our results indicate that more detailed research is needed to understand the interaction of various factors influencing transportation and accumulation of marine litter in the Black Sea.
