Comments P.375 left column top paragraph: "Silicon, which represents 27% of the lithosphere, is an important component of the marine biogenic matter that accumulates in coastal and abyssal sediments. In this article [investigators] focus on the marine biogeochemical cycle of Si (Fig. 1), covering time scales from 1 to 10,000 years. Dissolved Si in seawater occurs mostly (~95%) as the undissociated monomeric silicic acid Si(OH)4."
