Even if deepsea mining is often quite costly since big machines have to be operated on the ground of the ocean, many companies think it will still be worth it to do so due to the scarcity of resources from conventional mining activities which may lead to a significant increase in world market prices for scarce metals and therefore to an increased profit for companies who specialized in ocean
#0183;#32;Scientists are just beginning to discover the full richness of deepsea life. Yet already a number of companies and countries are exploring the deep ocean for minerals and developing the technology to mine some of the last untouched areas of our planet. A guest blog on deep sea mining from the Deep Sea Conservation Coalition.
#0183;#32;As deepsea biologists who study the drifting and swimming inhabitants of the ocean, we originally felt that any resulting harms from deepsea mining would primarily be
#0183;#32;Now, as the first deepsea mining project ramps up, nations are trying to hammer out guidelines to ensure this new quot;gold rushquot; doesn''t wreck the oceans
#0183;#32;However, four critical issues remain for deep mining in hard rocks: characterization of and methods to understand highstress fields and geological structures in deep mining; knowledge of fullblock fracturing for hard rock under high in situ stresses; support measures to control rockburst at high temperatures; and knowledge of the flow and coupling of the integrated solidgas

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.
Canadian mining company Nautilus Minerals has staked its reputation on bringing off the world''s first deep sea mining (DSM) operation. The Bismarck Sea in Papua New Guinea has been marked out as the testing ground for this unprecedented technology.
#0183;#32;Gold alone found on the sea floor is estimated to be worth 150 trn. But the cost to the planet of extracting it could be severe. Check out Economist Films:
With regulations permitting commercial deepsea mining due to be agreed in July 2020, the debate over whether the industry has a place in an environmentally and socially sustainable blue economy is hotting argue that deepsea mining has a vital role in supplying resources needed by the transition to a lowcarbon economy.
#0183;#32;Deepsea mining companies are hunting for these nodules to use in the technology industry, but scientists are concerned about the damage that could be done to the seabed and its inhabitants during
Deep below the oceans surface, precious minerals have spent millions of years building up on rocks and soft sediments. The deposits being eyed by deepsea prospectors come in three main flavors.
Impact on deepsea organisms. Life on the ocean floor moves at a glacial pace. Sediment accumulates at a rate of 1 millimeter every millennium. With such a slow rate of growth, areas disturbed by deepsea mining would be unlikely to recover on a reasonable timescale.
The international forum for deep sea mining professionals. As we move into an era of mining the deepocean floor, the worlds most remote environment, mining companies are working on overcoming the perceived challenges and developing island nations are watching with interest.
#0183;#32;The worlds oceans are facing a new industrial frontier from a fledgling deepsea mining industry as companies line up to extract metals and minerals from some of the most important
Mining operations in deeper waters have led to a very different results: When investors tried about 40 years ago to retrieve potatosized manganese nodules scattered on the ocean floor, almost half a billion dollars worth of prospecting couldnt make their efforts profitable.
Mining at deep sea. Deep inside the ocean is a world as vibrant and rich as the one outside. There are mountain ranges, ridges, forests, seamounts, volcanoes and a
