18 Φεβ 2021 · The element silicon (Si) is required for the growth of silicified organisms in marine environments, such as diatoms. These organisms consume vast amounts of Si together with N, P, and C, connecting the biogeochemical cycles of these elements.
26 Αυγ 2019 · The biogeochemical cycle of silicon (Si) interacts with relevant marine chemical and ecological processes, which include modulation of the primary production 1 and removal of atmospheric CO...
For nearly 20 years, the marine silica budget compiled by Tréguer et al. (1995), with its exploration of reservoirs, processes, sources, and sinks in the silica cycle, has provided context and information fundamental to study of the silica cycle.
3 Ιαν 2013 · For nearly 20 years, the marine silica budget compiled by Tréguer et al. (1995), with its exploration of reservoirs, processes, sources, and sinks in the silica cycle, has provided context and...
In the marine silicon cycle, silicon travels from the land into the oceans via rivers and groundwater. Near the ocean’s surface, silicon is taken up by phytoplankton like diatoms and incorporated into their skeletons. When these organisms die, they sink to the bottom of the ocean.
15 Σεπ 2017 · Key Points. Biogenic silica (bSi opal) is rapidly altered to authigenic clay phases (bSi clay) to variable extents depending on depositional environment. Tropical and subtropical deltas store 3.5–3.9 Tmol/yr of Si as authigenic clay (bSi clay ), and temperate proximal coastal zones store ~1 Tmol/yr.
12 Οκτ 2021 · The marine silica cycle is a complex process manipulated by biological (Si uptake by organisms， decomposition)， physical (adsorption of silicic acid and dissolution of bSi)， and chemical...
