Noise pollution from proposed deep-sea mining could radiate through the ocean for hundreds of kilometres, scientists predict, creating a “cylinder of sound” from the surface to the sea bed.

An analysis by scientists from Oceans Initiative in the US, the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, Curtin University in Australia and the University of Hawaii, published in the journal Science, has found that noise from one mine alone could travel 500km (more than 300 miles) in gentle weather conditions.

“The deep sea houses potentially millions of species that have yet to be identified, and processes there allow life on Earth to exist,” said Travis Washburn, a deep-sea ecologist at AIST.

The impact of noise pollution from deep-sea mining is “understudied and overlooked”, according to the report.
