Manganese
Manganese occurs in sea water usually as a divalent ion. Particulate manganese is not found in the sea except in surface waters. Although manganese has been proven to be necessary for growth of various phytoplankton species, it is found in very low concentrations in the sea, usually ranging from less than 0.001 to about 0.01ppm. |
