The deposit consists of polymetallic nodules, which are rock-like formations found on the ocean floor. These nodules naturally contain high concentrations of valuable metals, making them an ...

Saskia Birt uncovers the significant environmental stakes of deep-sea mining and its unforeseen role in oceanic oxygen production.

Mining of polymetallic nodules from the seabed might lead to significant and long-lasting ecological changes -- both in the mined area, where surface sediments and the fauna living in and on it are ...

Rules on deep-sea mining in international waters must be driven by "sound science" and built on consensus, the head of the ...

Commercial production of undersea mining could become a reality in less than five years, but at a potentially high cost to ...

Rules for the emerging deep-sea mining sector should take a "precautionary approach" that protects the environment, the head of the body drafting regulations for the practice told AFP Friday.
