Deep-sea mining targets mineral deposits on the ocean floor, typically at depths of 3,000–6,000 meters. Most attention focuses on polymetallic nodules—potato-sized rocks lying on abyssal plains—and on ...

A new study led by researchers at the University of Hawaii (UH) at Mānoa published in Nature Communications is the first of its kind to show that waste discharged from deep-sea mining operations in ...

Deep-sea mining is the extraction of minerals from the seabed in the deep ocean. Most of the interest is in what are known as polymetallic nodules, which are potato-sized mineral deposits that have ...

Scientists have discovered that deep-sea mining plumes can strip vital nutrition from the ocean’s twilight zone, replacing natural food with nutrient-poor sediment. The resulting “junk food” effect ...

Diverse life forms exist on and within the ocean floor. These primarily consist of microbes, tiny organisms that can cope with extreme environmental conditions. These include high pressures and ...
