Whales are known for their extraordinary communication abilities, and recent findings have confirmed just how far their calls can travel. According to NOAA, certain whale species can communicate with each other across distances of up to 1,600 kilometres in the ocean. This remarkable range is made possible due to the unique properties of sound in water and the special adaptations whales possess for producing low-frequency calls. Baleen whales, such as blue whales and fin whales, produce deep, low-frequency sounds that can travel vast distances without significant loss of energy. These low-frequency sounds, sometimes as low as 10 Hz, are ideal for long-distance communication because they face minimal absorption in seawater and can pass through the ocean’s “sound channel” layers effectively. The ability to communicate over such distances plays an important role in whale life. It helps them locate potential mates, coordinate migration routes, and share information about feeding grounds. In vast oceans where whales are separated by hundreds or thousands of kilometres, this communication ensures they remain connected despite physical distance. However, this natural phenomenon is being disrupted by increasing levels of underwater noise pollution from ships, industrial activities, and naval sonar. These human-made sounds often overlap with whale calls, reducing their communication range and affecting essential behaviours like mating, feeding, and navigation. Conservationists emphasise the urgent need to regulate ocean noise levels to preserve this vital communication channel for whales and maintain the health of marine ecosystems.
