Tangled mess

In a mission to clean up trash floating in the ocean, environmentalists pulled 40 tons (36 metric tons) of abandoned fishing nets this month from an area known as the Great Pacific Garbage Patch.

Mariners on a 140-foot (43-metres) cargo sailboat outfitted with a crane voyaged from Hawaii to the heart of the Pacific Ocean, where they retrieved the haul of mostly plastic fishing nets as part of an effort to rid the waters of the nets that entangle whales, turtles, and fish and damage coral reefs.

The volunteers with the California-based non-profit Ocean Voyages Institute fished out the derelict nets from a marine gyre location where ocean currents converge between Hawaii and California during their 25-day expedition, the group’s founder, Mary Crowley, announced Friday.

The group is among a handful of non-profits working to collect plastic trash from the open ocean, an endeavour that can be dangerous, time-consuming, and expensive.

“Our success should herald the way for us to do larger clean-ups and to inspire clean-ups all throughout the Pacific Ocean and throughout the world. It’s not something that we need to wait to do,” Crowley said.

The cargo ship returned on June 18 to Honolulu, where 2 tons (1.8 metric tons) of plastic trash were separated from the haul of fishing nets and donated to local artists to transform it into artwork to educate people about ocean plastic pollution. The rest of the refuse was turned over to a zero emissions energy plant that will incinerate it and turn it into energy, she said.

A year before they went to pick up the nets, the Sausalito, California-based group gave sailors going from California to Hawaii buoyant GPS trackers the size of bowling balls to attach to the nets they encountered during their voyage so they could be tracked.


The group then sailed to collect the nets entangled with plastic chairs, bottles, and other trash in an effort that cost $300,000. The group plans to deploy dozens more GPS trackers and next year, embark on a three-month trash-collection expedition, Crowley said.

It is estimated that between 600,000 and 800,000 metric tons of fishing gear is abandoned or lost during storms each year in the oceans, said Nick Mallos, director of the Trash Free Seas Program at Ocean Conservancy, a non-profit environmental advocacy group.

Another 9 million tons (8 million metric tons) of plastic waste, including plastic bottles, bags, toys, and other items, flow annually into the ocean from beaches, rivers, and creeks, according to experts.

The Ocean Voyages Institute is one of dozens of groups around the world trying to tackle the problem. Most focus on cleaning up beaches, ridding shores of abandoned fishing nets, traps, and other gear, and pushing for a reduction on single-use plastic containers.

Collecting the trash already in the gyres is also the goal of The Ocean Clean-up project, which was started by Dutch innovator Boyan Slat and last year first deployed a trash collection device to corral plastic litter floating in the Great Pacific Garbage Patch.

The group has raised millions of dollars from donors around the world, including San Francisco billionaire Marc Benioff.

The buoyant, 2,000-foot (600-metre) long boom was floating 800 miles (1,300 kilometres) from Hawaii’s coast when it broke apart under constant wind. After being repaired, it was redeployed earlier this month.
