Silicon flux and distribution of biogenic silica in deep-sea …
The burial flux of BSi (mmol m −2 yr −1) was calculated from the biogenic silica content (mmol g −1) in the surficial sediment as (4) BSi burial flux = mass accumulation flux × biogenic silica content. We could not estimate the fluxes at Stns. 03 and 41 because we did not conduct radioactive nuclide measurements there. 4. Results …
