The International Seabed Authority and deep seabed mining

The deep ocean below 200 metres is the largest habitat for life on Earth and the most difficult to access. The sea floor, just like the terrestrial environment, is made up of mountain ranges, plateaus, volcanic peaks, canyons and vast abyssal plains. It contains most of the same minerals that we find on land, often in enriched forms, as well as minerals that are unique to the deep ocean, such as ferromanganese crusts and polymetallic nodules.
