Box Fig. 14.3 Operation of the silicon pump in coastal ecosystems (Modified and redrawn from Del Amo et al. 1997)
Box Fig. 14.4 Global biogeochemical cycle of silicon in the
oceans. Units are teramoles of Si.year
À1 at the planet scale; the
inputs to the marine environment came from riverine inputs, partial
dissolution of atmospheric dust, the basalts of the ocean floor and
direct discharges from deep hydrothermal vents. These inputs are
balanced by burial in ocean sediments and continental margins
