Tracking Macroplastics Leeching Into Rivers from Space
Rivers are one of the main ways that plastics get into the world's oceans, and now we can identify where plastic waste accumulates from space. Researchers used data from the Worldview-3 satellite to identify and map plastic material and polymer-coated surfaces in a watershed on the US-Mexico border. They collected different waste from stream channels and then identified their specific infrared absorption features, matching them to satellite imagery.
