An emerging threat for the Pacific Ocean is the development of deep-sea mining. Deep-sea mining is aimed at extracting manganese nodules that contain minerals such as magnesium, nickel, copper, zinc and cobalt. The largest deposits of these are found in the Pacific Ocean between Mexico and Hawaii in the Clarion Clipperton fracture zone. [108]

[2] However, an exception to this is the Sargasso Sea which has no coastline and lies within a circular current, the North Atlantic ...
