In the 5 Podcast, Thomas Loudon investigates issues and solutions that create a more sustainable world one step at the time. In this episode he focusses on noise pollution in the ocean. Just because we don’t hear much when we stick our heads in the water, doesn’t mean that there isn’t sound there. In fact, sound is everywhere in the ocean – and it’s vital to marine life. It’s how sea creatures navigate, how they communicate, how they find mates and how they get to their next meal. And after millions of years of evolution, it used to be perfect. Then humans came along and added the sound of engines, airguns, sonar and more to the soundscape.

In this episode Thomas Loudon speaks to a marine biologist Nathalie Houtman, marine ecologist Serena Rivero and Michel André, the director of the Laboratory of Applied Bioacoustics in Barcelona, about the effects of our noise on life in the ocean – and even life on land. Frans Hendrik Lafeber explains how MARIN is making ships quieter. But we start with a man who had a close encounter with killer whales, and wonders whether noise played a role.
