Beached macrolitter (>2,5 cm) abundance and composition in the Russian (Eastern) part of the Barents Sea and the adjacent part of the Kara Sea was assessed for 2021-2023. Average densities of beach litter on the coasts are 675 items/100 m and 37 kg/100 m (0.27 items/m2 and 0.015 kg/m2). Annual litter budgets for Cape Zhelaniya beaches are 0.49 items/m2 per year and 0.023 kg/m2 per year. The northernmost tip of Novaya Zemlya is shown to be a beach litter accumulation hot-spot on Novaya Zemlya archipelago, where litter is brought by surface currents and trapped by sea ice margins. Up to 80 % of beached marine macrolitter is made of plastics, originating from vessels. A certain accumulation strip of a beach was identified (14 m - 27.5 m distance from the waterline), and significance of the beach backshore was shown in litter accumulation. Beach litter accounting methodologies on the Arctic beaches are discussed.
