The Great Deep Ocean Migration

In the early days of exploration, the deep-sea was thought to be largely devoid of life, a vast empty plain of mud wrapped around the world, too deep for living organisms to survive. But the more humans explore, the more life we discover in increasingly unexpected places, from the boiling water of hydrothermal vents, to […]

New species could help monitor impact of future deep-sea mining

NATURAL HISTORY MUSEUM LONDON (NHM) | 25 September 2017 “The sponges live on the ocean floor on metal-rich nodules. The region where they live is targeted by deep-sea mining companies interested in mineral extraction. Scientists believe they are likely the most abundant animal living on the nodules and could be a key indicator species for […]
