文摘

We study spatial and temporal changes of marine litter on the deep Arctic seafloor. Photographic surveys were undertaken by a towed camera system at two stations along latitudinal gradient. Litter densities at HAUSGARTEN are substantially higher compared with other locations, despite its remote location. Small-sized plastics increased between 2002 and 2014 indicating fragmentation of plastic litter. Temporal increase in litter counts at both stations indicates that the Arctic faces a pollution problem and that it is spreading to the north.
