“Punch in the gut” as scientists find micro plastic in Arctic ice

  • The researchers said the ice they sampled appeared to be at least a year old and had probably drifted into Lancaster Sound from more central regions of the Arctic

LONDON: Tiny pieces of plastic have been found in ice cores drilled in the Arctic by a US-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.
The researchers used a helicopter to land on ice floes and retrieve the samples during an 18-day icebreaker expedition through the Northwest Passage, the hazardous route linking the Pacific and Atlantic Oceans.
“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.
“When we look at it up close and we see that it’s all very, very visibly contaminated when you look at it with the right tools — it felt a little bit like a punch in the gut,” Strock told Reuters by telephone.
Strock and his colleagues found the material trapped in ice taken from Lancaster Sound, an isolated stretch of water in the Canadian Arctic, which they had assumed might be relatively sheltered from drifting plastic pollution

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 plastic just jumped out in both its abundance and its scale,” said Brice Loose, an oceanographer at the University of Rhode Island and chief scientist of the expedition, known as the Northwest Passage Project.
The scientists’ dismay is reminiscent of the consternation felt by explorers who found plastic waste in the Pacific Ocean’s Marianas Trench, the deepest place on Earth, during submarine dives earlier this year.
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.
But the plastic fragments — known as micro plastic — also served to highlight how the waste problem has reached epidemic proportions. The United Nations estimates that 100 million tons of plastic have been dumped in the oceans to date.
The researchers said the ice they sampled appeared to be at least a year old and had probably drifted into Lancaster Sound from more central regions of the Arctic.
The team plans to subject the plastic they retrieved to further analysis to support a broader research effort to understand the damage plastic is doing to fish, seabirds and large ocean mammals such as whales.
Funded by the National Science Foundation and the Heising-Simons Foundation in the United States, the expedition in the Swedish icebreaker The Oden ran from July 18 to Aug. 4 and covered some 2,000 nautical miles. 


At Davos, innovative products point to a sustainable future

At Davos, innovative products point to a sustainable future

  • A single tree that to bear 40 different types of apple

DAVOS: The World Economic Forum is not all about the fourth industrial revolution or the rise of AI.

You can also find all manner of strange and intriguing products on display from biodegradable plastic made from algae to wallpaper made from recycled corn husks.

One stand titled “How do you design a tree?” is part of a conservation effort where a single tree is designed to bear 40 different types of apple.

Another stand displays colored seaweed on a rack, showing how clothes can be dyed in a sustainable, non-chemically corrosive manner.

Propped along a large wall is Fernando Laposse’s wallpaper made of variations of purple corn husks that are reinforced with recycled cardboard and cork to create wallpaper and furniture. The husks come from corn that needs very little water and can be grown in the desert, which makes it all the more sustainable.

“This initiative helps the local economy as it brings in jobs and a resurgence of crafts and food traditions while also ensuring sustainability,” Laposse said.

Another display shows a machine that extracts pellets from a mixture of algae and starch and is used to create a thread that is the base of 3D printing. These sustainable, biodegradable plastics made from algae are being experimented with in different regions.

With the rise of deep fakes — a branch of synthetic media in which a person in an existing image or video is replaced with someone else’s likeness — another stand delivers a warning on the looming dangers of unregulated software.

The Davos forum prides itself on its sustainability, and key topics have included climate, mobility, energy and the circular economy. Everything is recyclable, and participants must download an application in order to keep up with the program and any changes — a move to cut down on paper waste.
