Summary

Image analysis of deep-sea camera surveys at two stations of the HAUSGARTEN Arctic deep-sea observatory found marine litter densities between 660 and 6,566 items per square kilometer, with no statistically significant difference between stations. The study contributes evidence that marine litter reaches and accumulates in remote Arctic deep-sea environments.

ResultsAreas of images were calculated via laser points (total area: 28,161 m 2 ).89 litter items were found in 82 images (N3: 41, HG IV: 48).Mean annual litter density was between 660 and 6,566 items km -2 .Litter densities of two stations were not significantly different p =0.4)
