• Deepsea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.
Deep Sea Mining. Deep sea mining is the process relating to the retrieval of resources from the ocean floor. Some of the minerals like metaliferous oxides and metaliferous sulfides occur in the deep ocean. Metaliferous oxides contain manganese, copper, nickel and cobalt. Metaliferous sulfides contain copper, lead, zinc, chromium and gold.
Pacific governments should not approve deepsea mining until more is known about its likely impact, says conservation biologist Mellie Samson Jr. Deep sea mining (DSM) is the new frontier in extractive mining. For the companies involved, as well as the governments that own the mining rights, it offers substantial profits.
