The Sound of Water

Helen Czerski and Tom Heap discover how new technology lets us listen in to the extraordinary sounds of the planet's waterways. From the deepest ocean to the tributaries, rivers and streams, this is an exploration of the sound made under water by animals, humans, and yes even plants. From the snapping of shrimp to the bark of a John Dory, Tom and Helen ask how sound travels through water, how loud it is and what is known about the purpose of these sounds. They ask what impact human activity is having on the watery soundscapes and their inhabitants. Joining Tom and Helen on this deep dive into sound are marine biologist Steve Simpson and acoustic ecologist Jack Greenhalgh.
