silica cycleCycling of silica in the maritime environment. Silicon commonly occurs in character as silicon dioxide (SiO2), also referred to as silica. It cycles from the marine environment, coming into generally by means of riverine runoff. Silica is faraway from the ocean by organisms which include diatoms and radiolarians that use an amorphous form of silica in their mobile walls.
