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 .
Polymetallic nodules on the deep seabed in the CCZ Example of manganese nodule that can be found on the sea floor. Polymetallic nodules are found at depths of 4–6 km (2.5–3.7 mi) in all major oceans, but also in shallow waters like the Baltic Sea and in freshwater lakes.
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
Advocates for deep sea mining argue extraction of rare metals is critical for electric car batteries necessary to develop a fossil-free economy. [47] Opponents argue seabed mining could wreak havoc on the world's oceans, which act as a carbon sink absorbing a quarter of the world's carbon emissions each year. [49] Greenpeace's Esperanza
The International Seabed Authority (ISA) estimates that the total amount of nodules in the Clarion–Clipperton zone exceeds 21 billion tons (Bt), containing about 5.95 Bt of manganese, 0.27 Bt of nickel, 0.23 Bt of copper and 0.05 Bt of cobalt. [13] The ISA has issued 19 licences for mining exploration within this area. [14]
