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 2...
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...
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.
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.
30 Ιουν 2016 · This book presents notions indispensable to the knowledge on the silicon biogeochemical cycle in ocean systems, first of all describing the main quantitative analysis techniques and examination of the major organisms involved in the cycle.
