A new study led by the University of Oxford has developed a high-resolution model to quantify the sources of plastic debris accumulating on beaches across the Seychelles and other island states in the western Indian Ocean. The results, published in Marine Pollution Bulletin, demonstrate that most of this waste originates from distant sources and not from the islands themselves.
The model simulated the movement of both land-based and marine types of plastic pollution across the world’s oceans. This used input data on ocean currents, waves, and winds, and plastic debris entering the ocean from coastal populations, rivers and fisheries, to predict plastic debris accumulation at 27 sites in the Seychelles and wider western Indian ocean.
