Inuit warn ‘rock concert-like’ noise from ships affecting Arctic wildlife

Calls for mandatory measures to reduce underwater noise pollution as melting ice opens up shipping routes

For centuries, narwhals and ringed seals have provided food for Inuit communities on the ice floes of Mittimatalik, or Pond Inlet, on northern Canada's Baffin Island. But now, the Inuit - who have hunted, trapped and fished in the region since long before the Hudson Bay Company opened its first Arctic trading camp here in 1921 - say they no longer find the narwhals where they should be. They say shipping noise is to blame.

Researchers have likened the passing of a single ice-breaker, increasingly present in the Arctic, to an underwater rock concert. Ship noise can be caused by everything from propellers to hull form to onboard machinery. It can disrupt activities that marine mammals need to survive, by shrinking their communication space, causing stress and displacing them from important habitats.
