The resulting budget recognizes significantly higher input and output fluxes and notes that the recycling of silicon occurs mostly at the sediment-water interface and not during the sinking of silica particles through deep waters.
18 Φεβ 2021 · This review highlights the significant progress that has been made in the past decade toward improving our quantitative and qualitative understanding of the sources, sinks, and internal fluxes of the marine Si cycle.
26 Αυγ 2019 · Inclusion of sponge spicules and radiolarians increases the global ocean biological sink of silicon by 28%, with 95% of that increase attributed to sponges, according to examination of sediments...
The remains of silicifiers, isolated from marine sediments, are effective archives of marine Si cycling at different depths within the water column, yielding key information about DSi supply and utilization by marine algae.
Abstract. The element silicon (Si) is required for the growth of silicified organisms in marine environments, such as di-atoms. These organisms consume vast amounts of Si to-gether with N, P, and C, connecting the biogeochemical cy-cles of these elements.
25 Μαΐ 2022 · Notably, the outcome in our study arises owing to a previously overlooked biogeochemical feedback in the marine silicon cycle induced by OA, not by an effect of elevated CO 2 on diatom...
22 Μαΐ 2024 · Photosynthetic diatoms dominate the marine silicon cycle, support productive fisheries and are especially efficient at exporting fixed carbon from surface to deep water via sinking particles...
