Climate Change. Part 32.
trash from the
"Great Pacific Garbage Patch."
About the Garbage Patches:
There are massive concentrations of mostly plastic debris floating in the oceans of the world. The most famous concentrations of debris have been collected and trapped within three areas of the North Pacific Gyre (NPG) a.k.a. the North Pacific Subtropical Gyre. A Gyre is a large system of circulating ocean currents. The NPG is one of five major ocean-wide gyres in the world. 1 Two are in the Pacific, two in the Atlantic and one in the Indian Ocean. There are 13 smaller gyres elsewhere in the world's oceans.
The NPG is located in a region ranging from about 135°W to 155°W and 35°N to 42° N. 1
Carey Morishige of the federal U.S. National Oceanic and Atmospheric Administration (NOAA) explains that much of the debris found in these areas are microplastics -- small bits of plastic (microplastics):
"... that are suspended throughout the water column. A comparison I like to use is that the debris is more like flecks of pepper floating throughout a bowl of soup, rather than a skim of fat that accumulates (or sits) on the surface. 3
There are three areas within the NPG where plastic rash is concentrated, called:
- the "Western Garbage Patch,"
- the "Subtropical Convergence Zone," and
- the "Eastern Garbage Patch," a.k.a. the "Great Pacific Garbage Patch." 3 It is about halfway between Hawaii and California.
According to the Office of Response and Restoration of NOAA's Marine Debris Program:
" 'Patch' is a misleading nickname, causing many to believe that these are islands of trash. Instead, the debris is spread across the surface of the water and from the surface all the way to the ocean floor. The debris ranges in size, from large abandoned fishing nets to tiny micro plastics, which are plastic pieces smaller than 5mm [0.2 inches] in size. This makes it possible to sail through some areas of the Great Pacific Garbage Patch and see very little to no debris." 4
A proposal and an attempt to clean up a garbage patch:
During 2012, Dutch student Boyan Slat, aged 18, delivered a TED speech in which he proposed the Ocean Cleanup project to remove plastic from the oceans.
Carolyn Gramling, writing for Science News, discussed the project. It involves a series of floating booms about 600 meters (1,970 feet) long that form a "U" shape. They are made made of HDPE plastic. A ship would tow the booms through the "patch," and herd pieces of plastic into a concentrated mess so that they could be more easily picked up by other vessels. The booms drag a 3-meter-long underwater skirt which will collect most of the debris that is located underwater near the surface of the ocean.
Laurent Lebreton, Ocean Cleanup’s lead oceanographer, estimated that the Great Pacific Garbage Patch is spread across 1.6 million square kilometers (618,000 square miles) which is about twice the size of the State of Texas.
More than 90% of the mass of the debris is made up of pieces that are 5 centimeters (2 inches) or larger in size. These form the debris that the cleanup project is designed to collect.
Project leaders believe that once the full fleet od booms is launched, they could remove 50% of the plastic in the Great Pacific Garbage Patch within five years, and 90% by 2040.
Environmental scientist Marcus Eriksen at the Los Angeles–based nonprofit group, the 5 Gyres Institute suggests that the Ocean Cleanup project goals are over-optimistic. He suggests that much of the estimated 5 trillion bits of ocean plastic in the oceans is quickly removed from surface waters by natural forces. 5 They now lie out of reach below the booms' skirts.
Eriksen notes that 5 Gyres and other conservation organizations believe that the most effective cleanup strategy is to reduce the use of plastics worldwide.
Adam Lindquist, the director of the Healthy Harbor Initiative in of Baltimore, MD, said:
"Any tech that’s removing plastics from the ocean is a good thing. But the actual worth is getting people to take the problem more seriously, so that we can move toward real solutions -- like source reduction."
2018-DEC: The project ran into a snag:
The Ocean Cleanup project's ship with its 2000 foot-long (610 meter) floating boom, was launched on 2018-SEP-08 from Los Angeles, CA. It headed to the Great Pacific Garbage Patch and its estimated 1.8 trillion pieces of trash, weighing a total of about 350 million tons (318 billion kilograms). The group planned to work there for a year. 6
Science News reported that during the Ocean Cleanup shakedown cruise:
"Wind and currents have pushed trash into the rig, but the setup hasn't’t kept the trash corralled as planned." 7
Unfortunately, the mission had to be aborted on 2019-JAN-02 because a fracture occurred near one end of the group of booms. An Ocean Cleanup representative said that on:
"Saturday, December 29th, unexpectedly, one of the tow heads, together with an 18-metre piece of floater pipe with two stabilizer frames, was found to be drifting away from the rest of Wilson. No prior indications were seen for such a thing to happen, so this came as a surprise for both the offshore crew and the engineering team onshore."
"Wilson" is the name given to the "U" shaped boom assembly.
The equipment was towed to Hawaii for repairs. They are expected to arrive there in mid January. 8
