Marine litter is а growing environmental problem affecting oceans and seas worldwide. Waste created by humans on land or at sea has been discharged into coastal or marine environments. Marine Strategy Framework Directive establishes the basis of integrated marine assessment taking into account the human pressures and their environmental impacts, including marine litter under Descriptor 10. In this study the composition and density of coastline debris were analysed as indicators of marine litter. Two monitoring campaigns for collection and identification of marine litter took place at Asparuhovo Beach (Varna) in 2019, covering the surveyed area of 8814 m2. In the spring campaign, 3608 items of artificial polymer materials, rubber, textile, paper, processed wood, metal and glass with a total weight of 19.591 kg were collected. Litter density was estimated at 0.41 items. m-2 in abundance and at 0.002 kg. m-2 in mass. In the autumn survey, the number of collected items decreased to 1461 items and the weight–to 4.189 kg. Compared to spring, the results for beach litter density manifested 2.4 fold decrease in abundance (0.17 items. m-2) and 4 fold decrease in mass (0.0005 kg. m-2). In both surveys, the artificial polymer materials prevailed in abundance–87% and 86% respectively. Cigarette buts, plastic/polystyrene pieces, industrial packaging, plastic cups and rings were predominant in marine litter composition. The Clean Coast Index classified the Asparuhovo Beach as ‘‘Moderate” beach in spring and as “Clean” in the autumn season.
