The world's largest collection of ocean garbage is growing.
The Great Pacific Garbage Patch, a collection of plastic, floating trash located halfway between Hawaii and California, has grown to more than 600,000 square miles, a study published Thursday finds. That's twice the size of Texas.
Winds and converging ocean currents funnel the garbage into a central location, said study lead author Laurent Lebreton of the Ocean Cleanup Foundation, a non-profit organization that spearheaded the research.
First discovered in the early 1990s, Lebreton said the trash in the patch comes from countries around the Pacific Rim, including nations in Asia as well as North and South America.
The patch is not a solid mass of plastic. It includes some 1.8 trillion pieces of plastic and weighs 88,000 tons — the equivalent of 500 jumbo jets. The new figures are as much as 16 times higher than previous estimates.
The research — the most complete study ever undertaken of the garbage patch — was published Thursday in the peer-reviewed journal Nature Scientific Reports.
Much of the garbage is rather large. "We were surprised by the amount of large plastic objects we encountered,” said Julia Reisser, also of the foundation. “We used to think most of the debris consists of small fragments, but this new analysis shines a new light on the scope of the debris."
The study was based on a three-year mapping effort conducted by an international team of scientists affiliated with the Ocean Cleanup Foundation, six universities, and an aerial sensor company.
Sadly, the Pacific patch isn't alone. The Great Pacific Garbage Patch is the largest of five known such trash collections in the ocean, Lebreton said.
