Highlights The new technique relies on data from NASA`s Cyclone Global Navigation Satellite System (CYGNSS) CYGNSS also uses radar to measure ocean roughness New York: Scientists from the University of Michigan have developed an innovative way to use NASA satellite data to track the movement of tiny pieces of plastic in the ocean. Microplastics formed when plastic trash in the ocean breaks down from the sun`s rays and the motion of ocean waves. These small flecks of plastic are harmful to marine organisms and ecosystems. Currently, the main source of information about the location of microplastics comes from fisher boat trawlers that use nets to catch plankton - and, unintentionally, microplastics.
