A recent study co-authored by Dr Asha de Vos reveals that proposed deep-sea mining in the Clarion-Clipperton Zone (CCZ), Pacific Ocean, could expose marine life to chronic underwater noise — and most species aren’t prepared for it.
From invertebrates and sound-producing fish to majestic cetaceans, many organisms rely on sound for communication, navigation, foraging, and avoiding predators. Yet, only about 35% of species in the CCZ have been studied for noise sensitivity, leaving a huge knowledge gap in one of the ocean’s last quiet frontiers.
The study highlights the importance of establishing baseline data, implementing shared acoustic monitoring, and developing precautionary management frameworks to safeguard deep-sea biodiversity before commercial mining operations expand.
The deep sea may be far from sight, but it cannot be out of mind.
