Synopsis: The biogeochemical cycle of silicon in the ocean: Chemical forms, techniques of analysis, the silicifiers, processes of biogenic silica production and control mechanisms, mechanisms of dissolution, silicon in the major oceanic regions, global cycle and relationship with the biological carbon pump. This book proposes to establish the state-of-the-art on the biogeochemical cycle of silicon in the modern marine environment. It aims to provide a basic outline of: the chemistry of particulate and dissolved silicon, including the standard methods of analysis, the description and the role of living organisms and physico-chemical processes involved in the mechanisms of transformation of siliceous material, the key position of this element in the biogeochemical dynamics of major ocean regions, and finally its global biogeochemical cycle.
