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. However DSM is still experimental in nature, with potentially vast adverse environmental effects.
The international forum for deep sea mining professionals. As we move into an era of mining the deep-ocean floor, the world's most remote environment, mining companies are working on overcoming the perceived challenges and developing island nations are watching with interest.
Deep sea mining or underwater mining is the process of retrieving new minerals from the ocean floor. Deep sea mining sites are generally located in close proximity to areas around hydrothermal vents or polymetallic nodules, which are present at depths of 1400m to 3700 m in the ocean.
Jun 11, 2018· Most attractive of all for the mining industry are the potential riches at deep-sea hydrothermal vents. Known for nourishing lush communities of exotic life, the vents also can be treasure troves of high-grade minerals.
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 waters beyond national jurisdictions.
The technology for deep-sea mining is getting cheaper, and the price of some of these minerals is going up. Right now, for example, China has cornered the global market on rare earth minerals, and other countries want to get in the game.
Deep sea mining is a relatively new [when?] 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 (4,600 to 12,100 ft) below the ocean's surface. 
Overview. Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining.
Seabed Mining (SBM) is an experimental industrial field which involves extracting submerged minerals and deposits from the sea floor. There are interests both for and against seabed mining, however, the science around the environmental impact of SBM is incomplete and unproven.
What is Deep-Seabed Mining? Deep seabed mining is the extension of terrestrial and shallow-water mining activities in the deep ocean in the quest for minerals. It requires new technologies and approaches and new scientific knowledge, most of which have yet to be acquired and developed.
It is the third in a series of films produced by the Deep Sea Minerals Project, following "Under Pressure" which examined different stakeholders' perspectives involved with deep sea mineral resources in the Pacific, and "Out of Darkness," which focuses on environmental impacts of deep sea mining.
As the international deep sea mining community move ever closer to mining the deep-ocean floor, industry stakeholders from developing island nations and ocean regulators, to commercial deep sea miners and subsea technology companies come together annually to meet at the world's first and premier Deep Sea Mining Summit.
