Vanadium is a trace metal that is relatively abundant in the Earth (~100 part per million in the upper crust). [1] Vanadium is mobilized from minerals through weathering and transported to the ocean. Vanadium can enter the atmosphere through wind erosion and volcanic emissions [1] and will remain there until it is removed by precipitation. [1]
Vanadium is a chemical element; it has symbol V and atomic number 23. ... Particularly in the ocean, vanadium is used by some life forms as an active center of ...
The Earth's crust is one "reservoir" for measurements of abundance. A reservoir is any large body to be studied as unit, like the ocean, atmosphere, mantle or crust. Different reservoirs may have different relative amounts of each element due to different chemical or mechanical processes involved in the creation of the reservoir. [1]: 18
Hemovanadin is a pale green vanabin protein found in the blood cells, called vanadocytes, of ascidians (sea squirts) and other organisms (particularly sea organisms). [1] It is one of the few known vanadium-containing proteins. [2] [3] The German chemist Martin Henze first detected vanadium in ascidians (sea squirts) in 1911.
Vanabins (also known as vanadium-associated proteins or vanadium chromagen) are a group of vanadium-binding metalloproteins. Vanabins are found almost exclusively in the blood cells, or vanadocytes, of some tunicates (sea squirts), including the Ascidiacea. The vanabins extracted from tunicate vanadocytes are often called hemovanadins.

Deep sea mining is the extraction of minerals from the seabed of the deep sea. The main ores of commercial interest are polymetallic nodules , which are found at depths of 4–6 km (2.5–3.7 mi) primarily on the abyssal plain .
The vanadyl or oxovanadium(IV) cation, VO 2+, [1] is a functional group that is common in the coordination chemistry of vanadium. Complexes containing this functional group are characteristically blue and paramagnetic. A triple bond is proposed to exist between the V 4+ and O 2− centers. [2]
