Much of the ocean has never been mapped, and it is for this reason that projects like Seabed 2030 exist, to finally map every ocean. Just over a quarter of the oceans’ floor has been mapped ...

An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that ...

World leaders gathered for the UN Ocean Conference in Nice on Monday called for strict rules to govern deep-sea mining and warned against racing to exploit the ocean floor. This comes amid growing ...
