The latest research by scientists has shown that at least 14 million tons of pieces of plastic less than 5 mm wide are at the bottom of the oceans. Analysis of ocean sediments shows that there may be 30 times more plastic on the bottom than on its surface.
The Australian government research agency CSIRO has published a study of the seabed of marine sediments from 6 different locations in the Great Australian Gulf. With the help of an underwater research robot, samples were collected up to 380 km from the coast at depths of up to 3,000 meters. meters. After analyzing the latest data, scientists found that their estimated weight of microplastics on the ocean floor is 34 times bigger than that on its surface.
