Increase of litter at the Arctic deep-sea observatory HAUSGARTEN.
a b s t r a c t Although recent research has shown that marine litter has made it even to the remotest parts of our planet, little information is available about temporal trends on the deep ocean floor. To quantify litter on the deep seafloor over time, we analysed images from the HAUSGARTEN observa...
