Twice the Size of Texas

Fish inside of a caulking tube
If you have spent time on the water in the blue water part of the oceans on this Earth, you’ll know what I’m talking about when I speak of debris. I have never seen what is described here, but it sounds awful:
In this remote patch of the Pacific Ocean, hundreds of miles from any national boundary, the detritus of human life is collecting in a swirling current so large that it defies precise measurement.
Light bulbs, bottle caps, toothbrushes, Popsicle sticks and tiny pieces of plastic, each the size of a grain of rice, inhabit the Pacific garbage patch, an area of widely dispersed trash that doubles in size every decade and is now believed to be roughly twice the size of Texas. But one research organization estimates that the garbage now actually pervades the Pacific, though most of it is caught in what oceanographers call a gyre like this one — an area of heavy currents and slack winds that keep the trash swirling in a giant whirlpool.
Scientists say the garbage patch is just one of five that may be caught in giant gyres scattered around the world’s oceans. Abandoned fishing gear like buoys, fishing line and nets account for some of the waste, but other items come from land after washing into storm drains and out to sea.
Plastic is the most common refuse in the patch because it is lightweight, durable and an omnipresent, disposable product in both advanced and developing societies. It can float along for hundreds of miles before being caught in a gyre and then, over time, breaking down.
These giant whirlpools are where the garbage itself becomes encrusted with organisms and turned into floating carriers. As the organisms grow and multiply, their weight sinks the debris slowly, causing it to go down far enough to kill what it is on it and shed what is on it and then pop back up to the surface to do it all over again:
There are researchers trying to do comparative analysis of this problem:
Charles Moore found the Pacific garbage patch by accident 12 years ago, when he came upon it on his way back from a sailing race in Hawaii. As captain, Mr. Moore ferried three researchers, his first mate and a journalist here this summer in his 10th scientific trip to the site. He is convinced that several similar garbage patches remain to be discovered.
“Anywhere you really look for it, you’re going to see it,” he said.
Many scientists believe there is a garbage patch off the coast of Japan and another in the Sargasso Sea, in the middle of the Atlantic Ocean.
Bonnie Monteleone, a University of North Carolina, Wilmington, graduate student researching a master’s thesis on plastic accumulation in the ocean, visited the Sargasso Sea in late spring and the Pacific garbage patch with Mr. Moore this summer.
“I saw much higher concentrations of trash in the Pacific garbage patch than in the Sargasso,” Ms. Monteleone said, while acknowledging that she might not have found the Atlantic gyre.
Ms. Monteleone, a volunteer crew member on Mr. Moore’s ship, kept hoping she would see at least one sample taken from the Pacific garbage patch without any trash in it. “Just one area — just one,” she said. “That’s all I wanted to see. But everywhere had plastic.”
Yes, it is everywhere. It sounds like the Pacific Ocean truly has a problem with this trash. Finding a way to clean it up and turn the plastic into something that can be safely disposed of is a problem we could try to solve with better technology. An organization called Project Kaisei, cited in the article, is looking for a viable way to study this debris and use the material positively and wisely.
