  • The net inputs of silicic acid (dissolved silica) to the world ocean have been revised to 6.1 � 2.0 teramoles of silicon per year (1 teramole = 1012 moles). The major contribution (about 80 percent) comes from rivers, whose world average silicic acid concentration is 150 micromolar. These inputs are reasonably balanced by the net ouputs of biogenic silica of 7.1 � 1.8 teramoles of silicon per year in modern marine sediments. The gross production of biogenic silica (the transformation of… CONTINUE READING
