Deep ocean minerals are three distinctly different layers of ocean water - Surface Sea Water, Deep Ocean Water (DOW) and Very Deep Ocean Water. Each layer remains separate and autonomous from the others, moving at different speeds and directions from different kinetic forces and having different temperatures, densities and life form status. "The surface sea water layer" is influenced by sunlight penetration and circulates rapidly in unison with the seasons and wind patterns to a depth of 250 meters. It supports micro and animal life. "The middle layer is DOW" where the water is free of sunlight and life forms. It is characterized
