DEEP sea mining could send its noise up to 500 kilometres across the ocean, according to a report from Curtin University.

The analysis has scientists calling for limits on this kind of mining, as many deep sea creatures are believed to use sound to navigate and communicate.

The noise pollution creates a “cylinder of sound” from the surface to the seabed.

Many deep sea species — about which very little is known — are believed to use sound and vibrations to navigate, communicate and detect predators in the absence of sunlight.

Underwater noise is likely to “disrupt ecosystems”, said the authors of the paper.
