P.487 4th paragraph: "Opal rain rate and recycling at the water-sediment interface: Summing the net accumulation
rates of opal [FB(netdeposit)] and the pore water recycling flux [FD(benthic)] across the sediment-water interface gives the silica rain rate [FS(rain)], i.e., the rate of silica deposition on the seafloor (Figure 1, Table 2). Ragueneau et al. (primary source) compared the reconstructed burial rate with the directly measured flux of silica into sediment traps moored just above the nepheloid layer (data not shown in Table 2) for typical ecosystems of the world ocean. The two approaches usually gave comparable rain rates." P.487 bottom paragraph: "The diffusive flux of DSi [dissolved silicon] at the water-sediment interface [FD(benthic)] was previously estimated at 23±15 Tmol Si/year (see Tr´eguer et al. 1995, table 2), based on a set of measurements." See notes beneath table. 1Tmol=1 teramole = 10^12 moles |
