New method for looking plastic in oceans will testing so soon

A new method for searching for floating macroplastics, based on automated self-learning processing of satellite images, was presented by researchers at the Plymouth Maritime Laboratory in the United Kingdom; on April 23, the results of testing in a scientific journal were published.

The method allows the detection of floating plastic larger than 5 millimeters using data from the Sentinel-2 near-Earth satellite systems of the European Space Agency. Identification plastic is based on the long waves of the visible and infrared ranges absorbed or reflected by debris floating on the surface of the water. The classification of images obtained by the software product is ACOLITE.

Successful testing of a new feature for the detection of macroplastics in different places of the planet: Accra (Ghana), the islands of San Juan (Canada), Danang (Vietnam) and eastern Scotland (Great Britain). Accuracy from 86% to 100%. The authors intend to enhance the effectiveness of the application of unmanned aerial vehicles.

Recall, according to WWF, the annual volume of plastic emitted into the oceans is about 9.5 million tons. This is a third of all ocean debris. The ingress into water when it forms microorganisms tones and collapses to a size less than half a centimeter - microplastic. In the body of marine life. So microplastic was found even in the body of crustaceans from the Mariana Trench.
