Seabed mining

Seabed mining, also known as seafloor mining 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. The increased requirement for minerals and metals used in the technology sector has led to a renewed interest in the mining of seabed mineral resources, including massive polymetallic sulfide deposits around hydrothermal vents, cobalt-rich crusts on the sides of seamounts and fields of manganese nodules on the abyssal plains. While the seabed provides a high concentration of valuable minerals, there is an unknown risk of ecological damage on marine species because of a lack of data.
