World - Report: Deep-sea mining noise endangers marine life

The industry is aware that noise pollution is a problem, one miner said.

Noise pollution from deep-sea mining operations would have a deleterious impact on marine life, a new report from NGO OceanCare said.

OceanCare, based in Switzerland, holds Special Consultative Status on marine issues with the Economic and Social Council of the United Nations.

Levels of noise pollution generated by humans have increased every decade since the 1960s, ocean policy expert Cyrill Martin of OceanCare said.

"Deep-sea mining would take noise pollution to a whole new level, due to the presence of loud noise sources throughout the entire, very deep water column and the very long duration of noise emissions," he said.

Noise levels of underwater mining activity would be "several hundred times louder" than those of a space-rocket launch, the report states.

Noise pollution has already been found to have an impact on marine life, Dalhousie University marine biologist Lindy Weilgart said. "Adding another source of constant and loud noise without further research about the impacts and without significant efforts to reduce the noise would be utterly irresponsible.
