How the mournful songs of icebergs reverberate around the world

How the mournful songs of icebergs reverberate around the world Getty Images Antarctica’s biggest icebergs act like giant tuning forks when they collide with each other and the sea floor Icebergs produce some of the loudest natural noises in the oceans. Meanwhile, in the Arctic Ocean, icebergs create a different, but almost as deafening, noise as they calve off Greenland's enormous tongues of glacier ice and break apart. Listen to the sound of icebergs being born in Greenland – the loudest sound in the Arctic But the noise produced by icebergs isn't just of interest to climate researchers. "The loudest noise is usually associated with iceberg capsize, which occurs after calving at glacial fronts," says Evgeny Podolskiy, an associate professor at the Arctic Research Center of Hokkaido University in Japan. This, the researchers from University of Brest, France, suggest, could be because the whales are compensating for changes in the noise produced by icebergs as the climate changes as the harmonic songs produced by giant icebergs occur at similar frequencies to the calls of blue whales and other whales in the Southern Ocean.
