Satellites and light reflections help environmentalists spot coastal plastic waste

Geospatial scientists have found a way to detect plastic waste on remote beaches that are not visible in conventional satellite images, bringing us closer to global monitoring options. Millions of tons of plastic enter the oceans every year. While stopping this flow is crucial, so is tracking down what's already there so we can clean it up. This cutting-edge research harnesses the latest in satellite technology to do just that. The study, now published in Remote Sensing, used the unique infrared signals reflected by plastics to identify even tiny scraps amongst vast stretches of sand and rocks.
