“…However, reliable data on litter (plastic) sea-floor pollution in harbors are scarce [17]. From a fishing port in Turkey, over 300 kg of seabed litter was extracted in 2017 [18]. In 2020, in Newport harbor (USA) scuba divers collected over 2000 kg of marine litter [19].…”

The macro-litter (plastic) sea-bottom pollution of 14 city harbors and marinas in North Africa and in the western Baltic Sea was investigated using a new simple mobile underwater camera system. The study was complemented by a harbor-manager survey and 3D hydrodynamic transport simulations. The average pollution in German marinas was 0.1 particles/m2 sea floor (0.04–1.75). The pollution in North African marinas on average was seven times higher (0.7 particles/m2) and exceeded 3 particles/m2 in city-center harbors. The resulting > 100,000 litter particles per harbor indicate the existence of a problem. At 73–74%, plastic particles are dominating. Existing legal and management frameworks explain the lack of plastic bottles and bags on sea floors in Germany and are one reason for the lower pollution levels. Items that indicate the role of untreated sewage water were not found. Harbor festivals seem to be quantitatively irrelevant for open sea-bottom pollution. Our method tends to underestimate the pollution level. Model simulations indicate that storms can cause litter reallocations and sediment cleanings. However, marina sea-floor monitoring is recommendable because it addresses pollution hotspots, is cost-effective and takes place close to emission sources. Further, the effectiveness of land-based pollution-reduction measures can easily be assessed.
