A massive net is being deployed to pick up plastic in the Pacific - solar powered street lights

The days of the Pacific garbage patch may be numbered.
A highly anticipated project to collect plastic from large ocean debris is ready to launch phase 1 from Alameda, California
September 8.
The project's creators said their system could clear 90% of the plastic in the patch by 2040.
The Marine cleaning system was originally composed of a winding boom, when he was only 18 years old, designed to simulate a free
Floating coastlines can basically dump plastic into recyclable piles.
The project, located in Delft, The Netherlands, has received over $30 million in donations from sponsors, philanthropist and crowdfunding events.
It also raises the anger of researchers who are concerned about possible negative effects on marine life, or they say the project does not solve the problem of most marine plastics
A part less than half a centimeter called micro-plastic.
The system is designed to capture plastic debris ranging in sizes from a few millimeters to dozens of meters, such as fishing nets.
Critics are also concerned that the project will divert attention and money from the root of the problem: first, excessive waste of plastic.
A 2015 study led by Lorang Lebreton, chief oceanographer for ocean cleaning, estimated that the Pacific garbage patch was scattered in about one place.
6 million square kilometers
Twice the size of Texas.
In a huge ocean vortex known as the North Pacific gyre.
The study found that this patch is mainly composed of floating plastics (such as polyethylene and polypropylene) floating on the surface ().
Most of these pieces are less than half a centimeter.
But scientists estimate that in terms of quality, more than 90% of patches are made up of 5 centimeters or larger pieces.
The cleaning system will run into larger pieces.
The system uses 600-meter-
As an artificial coastline, a long row of unfixed boom moving with the spread of wind, waves and ocean currents.
Under the surface, drag the boom 3-meter-
Long dress, only the smallest plastic can escape from the skirt.
The water flow naturally pushes the boom line into the u-shape
Shape, gather plastic particles so that they are easier to collect.
Prosperity is also deceived by solar power.
Power Light, defense
Avoid ship collision systems and satellite antennas to help project scientists track the location of the system.
On a regular basis, support ships ship the collected plastic debris back to land for recycling.
The "System 001" launched in September 8 will be the beta test of the first fleet of about 60 such systems planned, although parts of a system have been tested for durability and performance outside the North Sea and California.
Lebreton said that once started, the 001 system will be tested on site for two weeks on the California coast.
If all goes well, it will reach the North Pacific gyre within five weeks of the launch date.
"We hope to bring the first plastic back by the end of the year," he said . ".
Marine clearing said that once the entire fleet is put into use, it will remove 50% of the plastic on the land within five years and 90% of the plastic by 2040.
Since the Pacific Great Garbage strip is located in international waters, no environmental impact assessment is required to start the device.
Nevertheless, the Foundation stated that it was commissioned by an independent advisory group, which was published in July.
The report focused on how the system might affect marine life and found no cause of serious concern, but identified a modest concern that turtles might be drawn into the system and then take in plastic.
But the assessment does not cover many issues, says Kim Martini, a physical oceanographer in Seattle. based Sea-
The science of birds that makes instruments for measuring marine properties.
In an article on the January 2017 Ocean blog, Deep Sea News, Martini includes, from algae to rattan pots and other kinds of creatures, whether the sweeping net can accumulate the resistance and stress of the Marine rider that may change the fluid dynamics of the system.
Matini said that there is another question, is whether to put the Plasticine in the garbage
May attract more wildlife).
Despite previous test deployments, "will they start collecting these things", there is no evidence yet that the system can actually collect a lot of plastic, Mardini said. “This [deployment]
Is the real touchstone. So we’ll see.
"Los Angeles nonprofit environmental scientist Marcus Eriksson also suspects the system will collect as much plastic as project scientists claim.
A 2014 study he co-wrote with Lebreton said an estimated 5 trillion of marine plastic debris worldwide.
"Debris has a lot of tearing, crushing, sinking", so many small particles will now sink to the 3-of the project-meter-
It's a deep skirt, Eriksson says.
At the same time, new particles always enter the ocean.
That's why 5 Gyres and other conservation organizations use prevention as the most effective clean-up strategy, says Eriksen: first convince people to use less plastic.
"It's actually upstream if you want to mitigate this damage.
"The Marine cleanup representative said that their project was designed to work in tandem with these upstream measures.
The team believes that even while trying to change human behavior, it is still worth trying to remove anything floating near the surface.
"The key is that we want to collect as much as we can," Lebreton said . ".
Regardless of the outcome of this deployment, some groups trying to solve the problem of plastic waste applauded the ocean clean-up work to raise awareness of the problem.
Adam lindst, director of the Baltimore Health Harbor initiative, said: "I like the enthusiasm of people for the marine cleanup project . ".
His team installed a pair of moored but floating "water trucks" with boom and skirt "--nicknamed Mr.
Professor of garbage wheel and garbage wheel
At the two estuary of the city's Inner Harbor.
In four and a half years, the two, from contact lenses to mattresses, dug up about 900 tons of debris to try to catch the garbage before it enters the ocean.
"Any technology to remove plastic from the ocean is a good thing," Lindquist said . ".
"But the real value is for people to take this issue more seriously so that we can move towards a real solution --
Like source reduction. reduction. ”
