LONDON - Tiny pieces of plastic have been found in ice cores drilled in the Arctic by a U.S.-led team of scientists, underscoring the threat the growing form of pollution now poses to marine life in even the remotest waters on the planet.
“We had spent weeks looking out at what looks so much like pristine white sea ice floating out on the ocean,” said Jacob Strock, a graduate student researcher at the University of Rhode Island, who conducted an initial onboard analysis of the cores. The team drew 18 ice cores of up to two meters in length from four locations, and saw visible plastic beads and filaments of various shapes and sizes. The scientists said the findings reinforce the observation that micro plastic pollution appears to concentrate in ice relative to seawater.
The Northwest Passage Project is primarily focused on investigating the impact of manmade climate change on the Arctic, whose role as the planet’s cooling system is being compromised by the rapid vanishing of summer sea ice.
