Seafloor litter from the continental shelf and canyons in French Mediterranean Water: Distribution, typologies and trends
Seafloor litter has been studied both on the continental shelves (by trawling during 24 years) and in canyons (by ROV) of the French Mediterranean sea Water (FMW). On the continental shelf, mean densities range from 49.63 to 289.01 items/km2. The most abundant categories were plastic, glass/ceramics...

| description | Seafloor litter has been studied both on the continental shelves (by trawling during 24 years) and in canyons (by ROV) of the French Mediterranean sea Water (FMW). On the continental shelf, mean densities range from 49.63 to 289.01 items/km2. The most abundant categories were plastic, glass/ceramics, metals and textiles. Trend analysis shows a significant increase in plastic quantities during the study period. Plastics accumulate at all depths, with heavier items being found in deeper areas, while the continental slope-break appears as a clean area. The spatial distribution of litter revealed the influence of geomorphologic factors, anthropic activities, shipping route, river inputs. All the canyons are affected by debris but coastal canyons (Ligurian Sea and Corsica) were more impacted than offshore canyons in the Gulf of Lion. The FMW appears to be highly polluted with regard to values found in other areas, but lower than those observed in the Eastern Mediterranean.
•Time series of 23 years of seafloor litter data collected from bottom trawl surveys.•Use of three years of litter data collected in canyons from Remotely Operated Vehicle.•Marine litter assessment for the Gulf of Lion and eastern Corsica areas.•Spatial analyses allowing the identification of hot spots and temporal trends.•On the continental shelf, annual mean densities range from 49.63 to 289.01 items/km2.•The most common litter categories are plastics, glass/ceramic, metals and textiles. |
