Summary Introduction
Silica (Si) cycle is very much important for marine environment particularly in oceans. Large reserves of silica remains in the ocean and many aquatic microbes incorporate silica in their exoskeletons. Transport of organic material in near-surface water to deeper ocean waters through primary production is referred to as biological pump.
