Deep-sea mining technology is still in development but will probably include vacuuming nodules from the seafloor. Scraping and vacuuming the seafloor can destroy habitats and release plumes of sediment that blanket or choke filter-feeding species on the seafloor and fish swimming in the water column.
Seabed Mining | KASM | Kiwis against Seabed …
Seabed mining is an experimental industrial field, which involves extracting submerged minerals and resources from the sea floor, either by dredging sand or lifting material in any other manner. Globally and in New Zealand, sand has been the primary target; primarily for use in construction but recently, for replenishment of urban beaches.
Mining at deep sea - Down to Earth
The technology used for deep-seabed mining is different for different resources. But all the technologies follow the standard procedure of violating the sea floor, the water above and a massive reshuffling of habitats. Mining will introduce light to an environment where life thrives in darkness. This may attract or deter some fish or benthic species and alter their feeding and reproductive behaviours (see …
An eco-friendly strategy for undersea mining
There are three main techniques for exploring minerals in the deep sea – the mining of dead or extinct hydrothermal vents, the collection of poly-metallic nodules, and the scraping of sulphide deposits, which are also found on land. Each of these resources is found a different environment. The hydrothermal vents are usually in relatively shallow waters at about 1500m deep, whereas the nodule fields are …

valuable minerals in rich concentrations. Deep sea extraction technologies may soon develop to the point where exploration of seabed minerals can give way to active exploitation. The International Seabed Authority (ISA) is charged with formulating and enforcing rules for all seabed mining that takes place in areas beyond national jurisdiction. These rules are now under development. Environmental
Deep sea mining - Wikipedia
Deep sea mining is a 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 below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc. The deposits are …
