Plastic debris in the ocean

A study has measured the amount of plastic debris found in a region of the Atlantic Ocean over a 22-year period. US researchers, writing in Science, suggest the volume of plastic appeared to have peaked in recent years perhaps due to tighter marine pollution rules that prevent vessels dumping their waste at sea.

The team found plastic, most pieces measuring no more than a few millimetres, in more than 60% of 6,136 samples collected by dragging fine-meshed nets along the ocean's surface.

The researchers - from the US-based Sea Education Association (Sea), Woods Hole Oceanographic Institution and the University of Hawaii - described plastic as a "major contaminant".
