Deep Sea Mining

Deep sea mining is the practice of removing metals and minerals from the ocean’s seabed. Thousands of metres below the surface, deposits of these metals and minerals like manganese, nickel and cobalt have built up on the seafloor into potato-sized nodules over millions of years. To mine these metals, gigantic machines weighing more than a blue whale would scoop deposits from the deep ocean floor. They’d then pump the mined material up to a ship through up to several kilometres of tubing. Sand, seawater and other mineral waste would then be pumped back into the water.
Deep sea mining is a very new industry. Apart from a few small tests, no commercial mining has happened yet. But the companies involved are preparing to start full-scale production.

The Push for a Deep-Sea Mining Moratorium in 2025: Environmental Impacts and International Support

Deep-sea mining targets polymetallic nodules and other resources on the ocean floor, essential for batteries and renewables, but at a potential cost to biodiversity. As of mid-2025, the ISA has yet to finalize a mining code, leaving a regulatory void that environmentalists decry as a gateway to disaster . The proposed moratorium seeks a legally binding halt to commercial...

Deep-Sea Mining: Green Energy Savior or Irreversible Assault on Marine Biodiversity?

  Deep-sea mining targets polymetallic nodules on the ocean floor, rich in metals essential for electric vehicles and solar panels. Amid escalating demand, proponents hail it as a solution to mineral shortages, while critics decry potential irreversible harm to marine life. A 2025 Frontiers in Marine Science study estimates a single operation could destroy 300–700 km² of nodules and double...
