Today, 19 February, we celebrate International Whale Day, the giants of the seas that have roamed the oceans for millions of years. But did you know that their survival is threatened by an invisible enemy? Noise pollution is disrupting their migrations and their communication, which is essential to their survival.

🔊 Sounds are vital for cetaceans: whales use songs and acoustic signals to find their bearings, find food, communicate with each other over hundreds of kilometres and even reproduce. Yet noise generated by human activities (shipping, sonar, underwater infrastructure) disrupts these exchanges and can cause stress, disorientation and even tragic strandings.

🔬 The BIOSSA project – which we are supporting at Pure Ocean – is dedicated to understanding these impacts using satellites and autonomous marine drones. Using these innovative technologies, scientists are analysing the effects of underwater noise on cetaceans between Brazil and Chile, in order to propose concrete solutions to better protect these species.

💙 Let’s take action for a quieter ocean that’s safer for whales. Share this message and help us make their voices heard!
