Mining In The Deep Ocean

Jul 29, 2021 Deep-sea mining could be “the noisiest thing we’ve ever done in the oceans,” McCauley said. At least 25 species of whales and other cetaceans are known to pass through the CCZ, Amon said. One study found evidence that whales dive down to the seafloor in the mining region, probably to feed. Tuna also migrate through the area

    Jul 27, 2021 Out to sea. 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

    Seabed Mining (SBM) is a growing industrial field that involves extracting submerged minerals and deposits from the sea floor. To date, mining for sand, tin and diamonds has been generally limited to shallow coastal waters. Seabed Mining (SBM) should be distinguish from Deep Sea Mining (DSM) that occurs at a depth of 200 meters and greater
