Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
Model of seabed mining technology. 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. [23] [24] They are the most readily minable type of deep sea ore. [25]
The sea is the habitat of over 1,000 invertebrate species and 200 soft and hard corals and is the world's most northern tropical sea. The Red Sea is a rich and diverse ecosystem. More than 1100 species of fish [33] have been recorded in the Red Sea, and around 10% of these are found nowhere else. [34]

Polymetallic nodules are found in both shallow (e.g. the Baltic Sea [7]) and deeper waters (e.g. the central Pacific), even in lakes, [8] and are thought to have been a feature of the seas and oceans at least since the deep oceans were oxygenated in the Ediacaran period over 540 million years ago.
What's more, Granot thinks the ancient slab might be a remnant of Earth's long-lost Tethys Sea (or Ocean). RELATED: Deep ocean images from the Mariana Trench "[W]e don't have intact oceanic crust ...
A rarely seen deep sea fish resembling a serpent was found floating dead on the ocean surface off the San Diego coast and was brought ashore for study, marine experts said. The silvery, 12-foot ...
