Current deep-sea-mining proposals are expected to generate two types of sediment plumes in the ocean: “collector plumes” that vehicles generate on the seafloor as they drive around collecting nodules 4,500 meters below the surface; and possibly “midwater plumes” that are discharged through pipes that descend 1,000 meters or more into the ocean’s aphotic zone, where

    Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m which covers about 65% of the Earth’s surface. There is growing interest in the mineral deposits of the deep sea. This is largely due to depleting terrestrial deposits for metals such as copper, nickel, aluminium, manganese, zinc, lithium and cobalt, coupled with rising demand for these metals

    Seafloor Mining Hot, buoyant, mineral-laden fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor chimneys, and mineral particles in the fluids venting at the seafloor make the fluids look like smoke
