We've known for a long time the world has an ocean pollution problem stemming from plastic junk. We just didn't know how bad it had gotten.
The Great Pacific Garbage Patch is the name given to an area of the Pacific Ocean between California and Hawaii where plastics of all kinds have been accumulating into one big watery junk pile. It contains everything from plastic buckets to discarded fishing nets. A new study shows the patch is bigger than previously thought and is also growing at an astounding rate.
The team sent 30 vessels into the debris field simultaneously while also surveying the area by aircraft.
Most of the ships used surface-sampling nets, but the lead vessel used a trawling system to pick up bigger objects out of the patch. The fleet gathered 1.2 million plastic samples during the expedition.
The data now shows the garbage patch measures nearly 620,000 square miles (1.6 million square kilometers) and contains 1.8 trillion pieces of plastic that weigh as much as 500 jumbo jets. That's up to 16 times more plastic than shown in previous estimates.
Watch this: The Ocean Project is coming for the Great Garbage Patch
The Ocean Cleanup Foundation is developing technologies designed to remove plastics from places like the Great Pacific Garbage Patch. The organization has estimated its floating debris-gathering systems could clean up half the patch within five years, though a Guardian report from 2016 questioned the feasibility of the project.
The foundation expects to launch its first cleanup system in mid-2018. With this new data on the size and growth of the garbage patch, the group may be facing a bigger challenge than it originally expected.
