Mining In The Deep Ocean

[title]

Deep sea mining - Wikipedia

Deep sea mining is a relatively new [when?] mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean’s surface.The Race Is On to Mine the Deep Ocean, But Scientists,Those creatures offer potential resources for pharmaceuticals and can provide new insights to how life begins. Smith calls them “the raw material for evolution.” But they evolved in waters as deep as 18,000 feet that are largely free of ocean currents or the light, vibration, and noise that would result from mining.Should we mine the deep ocean? | Popular Science,The deep sea is home to three types of mineral formations that might be suitable for mining. The first are polymetallic, or manganese nodules, a kind of metallic nugget that rests on the sea floor. The second are polymetallic sulphides.
