Aug 29, 2021 Such prospects only strengthen the urgency of assessing the likely effects of deep-sea mining, say scientists. It is a point stressed by Andrew Sweetman, professor of deep-sea ecology at Heriot-Watt University, Edinburgh, who has been involved in carrying out deep-sea mining impact assessments for governments and mining companies

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

Jul 29, 2021 Researchers from the University of Exeter, UK, claim that deep-sea mining in international waters (which could start in as little as two years) could cause irreversible damage to aquatic ecosystems and affect many different marine species, according to a study published in the journal Frontiers in Marine Science (1). The deep-sea – areas below 200m – covers over half of our planet’s surface

Deep-sea mining is seabed mining at depths lower than 200 metres to extract rare metals and minerals such as copper, nickel, aluminium, manganese, zinc, lithium, cobalt, gold, and silver. Different types of pollution resulting from this type of extraction—including sound, light, vibratory, and physical damage as well as muddying, fuel leaks

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

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

1 day ago It is nonsense that this form of mining is a “light” alternative to terrestrial mining and that all the cobalt, nickel, copper and manganese lying “for the taking” on the bottom of the oceans are some kind of silver bullet. Far from being the answer to our dreams, deep seabed mining could well turn out to be the stuff of nightmares

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
