Nowadays, the management of plastic pollution has emerged as an extremely challenging issue. Eight million ton of plastic waste makes its way into oceans, seas, and rivers each year. Currently, Scientists are testing EU’s Sentinel-2 satellites to detect plastic debris in the ocean.
UK scientists are using Sentinel-2 satellites to track plastic pollution in the oceans.
The research is going to be really challenging as pieces of litter are minimum in size which satellite can track. Scientists have used plastic’s reflected light signature in the sea for the purpose and results are also encouraging.
Dr. Lauren Biermann from Plymouth Marine Laboratory said that “You’re never going to see an individual plastic bottle floating on the sea, but we can detect aggregations of this material”.
She further clarified that vegetation and plastic has a different signature thus we can start to un-mix the pixel.
Earlier, EU’s Sentinel-2 satellites have sent to space to get the evolving map of land surfaces on Earth. However, the satellite has taken the imagery of coastal waters too. The imagery will help to monitor plastic discharge in the ocean to make them pollution-free zones. Though early results need refinement but it will lead to further investigation.
