Australian, American and British oceanographers and zoologists went on a three-month expedition throughout the Southern Ocean following the sound of the blue whale in order to study the migration and population of the species. Sound waves have allowed scientists to get closer to the animals to be able to identify them.

Six hundred and twenty-six hours of sounds emitted by 26,545 blue whales were recorded. The researchers installed chips in some cetaceans, which will allow the animals to be followed by satellite.

This project - which also includes Brazil, Argentina, Chile, France, Germany, New Zealand, Norway and South Africa - is part of an international program to protect blue whales, endangered by decades of overfishing. Estimates indicate that in the early 20th century, there were 250,000 of them. Today, there are about 10,000.
