The article makes mention to the Pacific Garbage patch as a comparison
"The concentration of plastic debris [estimated from core samples of arctic ice] is 1,000 times greater than that floating in the so-called Great Pacific Garbage Patch."
- zaroth 12y agoWikipedia says GPGP has about 5kg of plastic suspended per square kilometer of ocean. 1 cubic meter of water is 1000 liters and 1000kgs. 1 square kilometer, and let's say all the plastic is within 1 meter of depth would be 1 million cubic meters of water, or 1billion kilograms. So another way to think about it is dilute plastic molecules at about 5 parts per billion. The big assumption is 1 meter depth, because if it's actually concentrated more like within 1cm of depth then it's 500 ppb.
