Add the remote North to the spots where the world’s plastic trash ends up floating.
A multinational expedition that skimmed the Arctic Ocean in 2013 found plastic “was abundant and widespread” in waters east of Greenland in the Barents Sea, off northern Russia and Scandinavia. In some parts of those waters, they found hundreds of thousands of pieces of plastic per square kilometer of surface, the researchers reported this week.
“The growing level of human activity in an increasingly warm and ice-free Arctic, with wider open areas available for the spread of microplastics, suggests that high loads of marine plastic pollution may become prevalent in the Arctic in the future,” the researchers warned.
The findings were published today in the journal Science Advances. The research team included scientists from Spain, Denmark, Britain, the United States, Japan, France, the Netherlands, and Saudi Arabia.
Nearly all the plastic was concentrated in the stretch between Greenland and the Russian islands of Novaya Zemla. Those waters “constitute a dead end” for the currents that flow northward from the Atlantic, bringing with them trash from the coasts of Europe and North America, the study found.
“The total load of floating plastic for the ice-free waters of the Arctic Ocean was estimated to range from around 100 to 1,200 tons, with 400 tons composed of an estimated 300 billion plastic items as a midrange estimate,” the scientists wrote.
