Seabed survey reveals depth of marine litter problem by mapping waste in Atlantic and Arctic oceans and Mediterranean.
Bottles, plastic bags, fishing nets and other human litter have been found in Europe’s deepest ocean depths, according one of the largest scientific surveys of the seafloor to date.
Scientists used video and trawl surveys to take nearly 600 samples from 32 sites in the Atlantic and Arctic oceans and the Mediterranean Sea, from depths of 35 metres to 4.5 kilometres. They found rubbish in every Mediterranean site surveyed, and all the way from the continental shelf of Europe to the mid-Atlantic ridge, around 2,000km from land.
Plastic was the most common type of litter found on the seafloor, accounting for 41%, while rubbish associated with fishing activities (discarded net and fishing lines) made up 34%. Glass, metal, wood, paper and cardboard, clothing, pottery and unidentified materials were also documented. Click here to continue reading.
