What is Deep Sea Mining?
Deep sea mining is a brand-new destructive industry on the precipice of starting, which would involve mining metals and minerals from the seabed. If allowed to start, this industry would damage the oceans beyond repair, possibly driving countless species to extinction.
Deep sea mining is the practice of removing metals and minerals from the ocean’s seabed. Thousands of metres under the sea, deposits of metals and minerals like manganese, nickel and cobalt have built up on the seafloor 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 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.
This is how we stop Deep Sea Mining, together
Hold governments accountable for deep sea mining
The Australian government has a vital role to play. We need them to show leadership and join others in calling for a moratorium to stop deep sea mining.
Amplify Pasifika voices calling for a ban
We can use your gifts to work with our global Greenpeace network to amplify the voices of Pasifika people standing up against deep sea mining and show the potential harm to ecosystems, which they are the custodians of.
Life underwater would be irreversibly harmed by deep sea mining. With your support, we can ramp up pressure, hold governments to account and guarantee protection for our deep oceans.

Our ancestors read the seas to navigate, to survive, to connect communities scattered across islands. Discoveries like this Dumbo octopus awaken something deeper in me, — a sense that the ocean is alive…
