Acoustic shock: how noise pollution disrupts ocean life

Subscribers Only
Babbage from The Economist
Sound is central to life underwater. The list of marine creatures that are known to rely on sound for navigation, communication and much more is growing, as is the awareness of the complex ways in which they use it. But as humanity has extended its footprint into the seas, it has done so noisily. The soundscape of the ocean has been thrown out of balance and researchers are now developing new technologies—from bubble screens to “acoustic black holes”—to protect marine life from the excessive noise. Host: Alok Jha, The Economist’s science and technology editor. Contributors: Moira Donovan, a journalist who writes for The Economist; Amorina Kingdon, science writer and author of “Sing Like Fish”, and Tom Smith of University College London.
