Around four billion minute fibres could be littering each square kilometre of some of the world’s deep seas, demonstrating that plastic debris is now creating cause for concern in some of the remotest parts of the marine environment.
That is one of the findings of a pioneering international study examining the scale of the presence of microplastics at depths of up to 3500m in parts of the Indian and Atlantic Oceans, and the Mediterranean Sea.
Existing research had shown that in recent decades plastic debris has become almost omnipresent on the world’s coastlines, but the extent of its concentration close to shorelines had not increased in line with predictions based on the production and use of plastic.
However, the current study – led by scientists from Plymouth University and the Natural History Museum – indicates this may be because microplastics have sunk to the ocean floor, with the number of fibres recorded as being up to four times more abundant in the deep seas than in shallow and coastal waters.
In fact, the current study has led scientists to suggest – in areas of the Indian Ocean at least – that around 4 billion fibres per km² would be present in seamounts.
