Deep sea mining is the extraction of minerals from the seabed of the ... Of this total resource, 304 million tons of nodules grading 0.5% Co, 0.15% Cu, 18.5% Fe, 15.4 ...
TMC the metals company Inc., [1] doing business as The Metals Company, formerly DeepGreen Metals, is a Canadian deep sea mining exploration company. [2] The company focuses on the mining of polymetallic (nickel, copper, cobalt and manganese) nodules [3] [4] in the Clarion Clipperton Zone of the Pacific.
Very little is known about deep sea ecosystems or the potential impacts of deep-sea mining. Polymetallic nodule fields are hotspots of abundance and diversity for a highly vulnerable abyssal fauna, much of which lives attached to nodules or in the sediment immediately beneath it.
The production of oxygen at the seafloor by polymetallic nodules is a new ecosystem function that needs to be considered when assessing the impact of deep-sea mining.
The International Seabed Authority is working to set regulations for deep-sea mining as companies engaged in the clean energy transition clamor for more minerals. The seafloor, especially in parts ...
The discovery that abyssal, or deep-sea, nodules are producing oxygen is “an amazing and unexpected finding,” said Daniel Jones, a professor and head of ocean biogeosciences at the National ...
Supporters say deep sea mining will help boost supplies of raw materials like cobalt and nickel, which are needed for the global energy transition, but critics say it could destroy ecosystems and ...
Model of seabed mining technology. Seabed mining, also known as Seafloor mining [1] is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains.
