You'd think the oceans are deep blue oases of peace. But actually they are deafening loud — and not by life underwater. The piling in the construction of windmills, the drilling for raw materials and the humming of marine engines disrupts animals and disrupts ecosystems.

Underwater, we have a growing problem: more and more human noise is heard in our oceans.

Underwater noise means poor biodiversity: we people do not want to live on a construction site either. The marine life is evolutionarily adapted to hear other frequencies and extract information from its environment, for example, to find and mate food.

Noise pollution therefore has more effect than we can hear. If you want to investigate the actual effect of humans on marine life, then you should not only look, but also listen, says biologist Hans Slabbekoorn. #diepzee
