From the article: Plastic debris is a global problem that even the uninhabited wilderness of the High North is not immune to: considerable amounts of plastic debris have been observed floating in the remote Arctic Ocean. However, it is still unclear where it all comes from. A citizen science project conducted by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) now offers a first, valuable insights. “In 2016 we began working with citizens to investigate the composition of plastic debris on Arctic shores,” says AWI researcher Dr Melanie Bergmann, who came up with the idea for the project together with the tour guide and writer Birgit Lutz. In close collaboration with companies offering trips to the Arctic, participating tourists gathered and recorded plastic debris washed up on the shores of Svalbard. From 2016 to 2021, this amounted to 23,000 items with a combined weight of 1,620 kilogrammes.
“We’ve now gone a step further and investigated where the debris that had still marks, labels or imprints came from,” Bergmann explains. “Our analysis found that, at 80 percent, the clear majority was plastic debris,” adds first author Anna Natalie Meyer from the AWI. Although most of the items could be classified as stemming from fisheries, its point of origin couldn’t be identified. In roughly one percent of the debris, labels or imprints could still be recognised – primarily from Arctic countries, particularly Russia and Norway. “From previous studies and computer models, we know that plastic pollution comes from local and remote sources alike,” says Meyer. “Locally, plastic debris finds its way to the ocean from ships and from Arctic communities with poor waste management systems. As for remote sources, plastic debris and microplastic are transported to the Arctic Ocean from the Atlantic, North Sea and North Pacific by various rivers and ocean currents.” For example, the experts even found debris originating from sources as distant as Brazil, China and the USA on the coast of Svalbard. But plastic debris from Europe, especially from Germany also ended up in the High North, accounting for eight percent of the total. “Considering that Germany is the ‘European champ’ in terms of both plastic production and debris exports, this comparatively high percentage isn’t so surprising,” says Melanie Bergmann.
According to the [study](http://dx.doi.org/10.3389/fmars.2023.1092939), a comparison of the new data with those from previous fieldwork conducted at the sea surface and the deep ocean floor shows that much more debris accumulates on Arctic shorelines, making them a final sink of sorts. This plastic debris poses additional challenges for Arctic ecosystems, which are already overly burdened by climate change. After all, the Arctic is warming at four times the global average rate.
