The Great Pacific Garbage Patch, or GPGP for short, is an accumulation of junk that has collected in the waters between California and Hawaii. The concentration of floating plastic in the patch ranges from tens to hundreds of kilograms per square kilometer. But much of it is hidden from the naked eye, partly because some of the plastic has been broken down into smaller and smaller bits over time. (It is not, as its name may suggest, an island.)
