Silicate forms an important parameter of phytoplankton distribution and its concentration in coastal water is influenced by proportional physical mixing of seawater with fresh water, adsorption of reactive silicate into suspended sedimentary particles, chemical interaction with clay minerals and biological removal by phytoplankton, especially by diatoms and silicoflagellates [28].
BSi, known as phytolith or opal, can be comprised of different components mainly of biological origin such as diatoms phytoliths, radiolarians, silicoflagellates and sponge spicules.
The small numbers of silicoflagellates and foraminifera were perhaps the result of undersampling of those single-cell organisms.
Diatoms are the most diverse (N = 171) and abundant taxa, followed by dinoflagellates (N = 84), silicoflagellates (N = 5), and cyanobacteria (N = 5; Garate Lizarraga 1992).
