How Shipping Noise is Changing Whale Songs

Underwater acoustic pollution from commercial shipping is forcing humpback whales to alter their communication patterns. Marine biologists track these changes over decades, revealing the hidden cost of global trade.

Whale songs travel hundreds of miles underwater, but increasing vessel traffic creates a "fog of sound" that disrupts mating calls, navigation, and social bonds. Some populations show signs of stress-related health issues linked to chronic noise exposure.

Solutions exist: slower ship speeds, quieter propeller designs, and seasonal quiet zones. This investigation profiles the scientists and activists working to make oceans audible again for their largest inhabitants.
