Nodules lie on the seabed sediment, often partly or completely buried. They vary greatly in abundance, in some cases touching one another and covering more than 70% of the sea floor surface. The total amount of polymetallic nodules on the sea floor was estimated at 500 billion tons by Alan A. Archer of the London Geological Museum in 1981. [6]
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. [23] [24] They are the most readily minable type of deep sea ore. [25]
TMC the metals company Inc., [1] doing business as The Metals Company, formerly DeepGreen Metals, is a Canadian deep sea mining exploration company. [2] The company focuses on the mining of polymetallic (nickel, copper, cobalt and manganese) nodules [3] [4] in the Clarion Clipperton Zone of the Pacific.
The production of oxygen at the seafloor by polymetallic nodules is a new ecosystem function that needs to be considered when assessing the impact of deep-sea mining. These findings underscore the ...

The term "polymetallic ore" also includes nodules, principally Manganese nodules, that do not form as terrestrial deposits but as concretions on the ocean floor. [3] [4] Rocks containing polymetallic ores are often altered or formed by hydrothermal processes — chloritization, sericitization and silicification.
The quiet CCZ, as wide as the continental U.S., is home to polymetallic nodules or trillions of potato-size lumps of matter formed over millions of years that contain nickel, manganese, copper, zinc and cobalt, as well as deep water coral, sponges and unusual species ("ghost octopus", crustaceans, worms and sea cucumbers) that in a near light ...
