The great pacific garbage patch gear and large pieces make up 92 percent of the trash Debris recovered from the Garbage Patch The Ocean Cleanup smithsonian. But for all the media coverage, researchers still didn't know a lot about it, until now.
As Laura Parker reports for National Geographica new study takes a closer look at the trash and the results suggest it's a bit different than we imagined.
The patch contains around 79, metric tons of trash, making it four to 16 times larger than previously estimated. First discovered inthe Great Pacific Garbage Patch was never a physical mass of objects, but rather a soup of tiny plastic debris.
Oceanographer and sailboat racer Charles Moore noticed the plastic soup while sailing his yacht in the Pacific ocean between Hawaii and California.
The patch in fact, there are two patches, a western and eastern patch is created by the North Pacific Subtropical Gyrea system of circular currents that tend to draw debris into its stable center, trapping it.
While the patch doesn't contain any "land" per se, it solidified in the popular imagination, often touted as a "floating mass" the size of Texas. Just last year, as a PR stunt, the conservation group Plastic Oceans Foundation and some advertising gurus petitioned the U. In a article debunking the myth, Daniel Engber at Slate described the patch as a soup of trillions of pieces of microplastics, which are created as plastic degrades.
Microplastics are also commonly included in many cosmetics.
Such itty bitty plastics can make their way into the food chain—and researchers are still sorting out the impacts. The latest research on the Garbage Patch, however, suggests it's made up of more than just tiny bits.
To get a handle on what's in the patch and just how large it is, a team of oceanographers commissioned by the conservation group Ocean Cleanup undertook a comprehensive study of the patch. According to a press releaseprevious studies were not able to accurately assess the volume of trash in the patch because they used small nets to sample the debris, which excluded larger chunks.
To remedy this issue, the Ocean Cleanup team used 30 boats that simultaneously surveyed the patch over the course of a summer, supplemented by two aircraft.
One of the ships trawled with two foot-wide devices, sampling for very large objects. The aircraft were outfitted with multispectral and 3D sensors to scan the ocean surface for large pieces of garbage as well.
The study appears in the journal Scientific Reports. The team found that the patch spans an area three times the size of France, containing 1.
Overall, this is the equivalent to the weight of jumbo jets. Surprisingly, they found that large pieces of plastic made up 92 percent of that mass, while microplastics accounted for only 8 percent.
It turns out, the patch is more like a chunky stew than a soup. That is the accepted number [for marine debris] globally—20 percent from fishing sources and 80 percent from land.
Perhaps counterintuitively, the fact that the patch is chunkier than expected is good news.
Great Pacific Garbage Patch: Great Pacific Garbage Patch, zone in the Pacific Ocean between California and Hawaii that has a high concentration of plastic waste. Ocean currents carry plastic debris into a subtropical gyre, where it remains trapped. The Great Pacific Garbage Patch, located between California and Hawaii, is carrying almost 80, metric tons of plastic — 16 times what scientists thought. Somewhere in the middle of the Pacific, an island has been forming, but don’t start packing your bags for a tropical adventure yet; this island isn’t one you would like to visit.
Cleaning up microplastics is very difficult, if not impossible, while recovering fishing gear might actually be a feasible task, but far from easy. That's why the Ocean Cleanup Foundationfounded by Dutch teenager Boyan Slat now 23 has been attempting to develop a system that will concentrate microplastics and debris for easier cleanup.
The Foundation's ambitious designs have garnered much criticism, and experts worry their methods could hurt wildlife. But oceanographers say something needs to be done, whether it's in the ocean or on land, where much of the pollution originates.The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific timberdesignmag.com is located roughly from °W to °W and 35°N to 42°N.
The collection of plastic, floating trash halfway between Hawaii and California extends over an indeterminate area of widely varying range depending on the degree of plastic. The Great Pacific Garbage Patch has received a lot of attention over the last couple decades.
But for all the media coverage, researchers still didn't know a lot about it, until now.
As Laura. The Great Pacific Garbage Patch contains up to 16 times more waste than previous surveys were able to detect and is growing exponentially, according to a new study.
