The map shows median of marine litter items by beach and marine region, based on Marine Litter Watch dataset in the period 2013-2020.

Regional differences in the levels and share of different litter groups/items can be depicted through the four regional seas of Europe. For the combined clean-up and monitoring data having only 90–850 m of beach length, the Black Sea (median 423 items) and Mediterranean Sea (median 346 items) coasts appear more polluted when compared to the north Atlantic Ocean (median 122 items) and Baltic Sea (median 74 items), being the median values standardized per 100 m of beach.
