In ‘a major breakthrough’, scientists are using algorithms to identify the clicks, calls and bleeps of marine life, as part of a 10-year project mapping noise under the sea.
On Goa’s coral reef in India, the marine scientists lowered their underwater microphones beneath the waves and recorded a complex cacophony of swirling currents, fish and plantlife.
But rather than spend months deciphering it using human ears, arguing over which click was a snapping shrimp and which snort a type of grunter fish, they plugged the sounds into an algorithm that correctly identified four species in a matter of minutes.
The discovery, published in The Journal of the Acoustical Society of America, was hailed last month as groundbreaking by the International Quiet Ocean Experiment (IQOE), a small but growing group of scientists around the globe who record the sounds of the sea.
