P.488 bottom paragraph: "Table 3 summarizes the available data [including those gathered by Nelson et al. (primary source) for the Southern Ocean] to delimit a range for the total diffusive flux of silicon from areas of the ocean containing biogenic silica in sediments." P.489 2nd paragraph: "Figure 1, which assumes that the marine silica cycle is at steady state (see below), shows tentative values for FS(rain) (78.8 Tmol Si/year) and FD(benthic) (72.5 Tmol Si/year) compatible
with Table 3, and an assumption that FD(benthic)/FS(rain) = 0.92, which is according to Table 2." See note beneath table. 1Tmol=1 teramole = 10^12 moles |
