What Scientists Discovered After 15 Years Of Research On Blue Whale Sound

Scientists spent 15 years listening to blue whales in the Antarctic using special buoys that can detect whale calls.
Scientists have completed a 15-year study on blue whales in the Antarctic, publishing their findings in a comprehensive sonic survey. Utilising passive acoustic devices called sonobuoys, researchers gathered nearly 3,900 hours of sound data, focusing on three distinct types of calls made by these elusive creatures.
The study, led by marine mammal acoustician Brian Miller from the Australian Antarctic Programme, sheds light on the distribution and behaviour of Antarctic blue whales, which were once hunted to near extinction during industrial whaling.
"This analysis represents the most contemporary circumpolar information on the distribution of these rarely sighted and elusive animals, which were hunted to the brink of extinction during industrial whaling," says Brian Miller.
