The marine component of SGD, driven by a range of physical processes such as density gradients or waves and tides, is fed by seawater that circulates through coastal aquifers or beaches via...
Diatoms have long been thought to dominate the marine silicon (Si) cycle, as well as play an important role in the ocean's carbon (C) export, due to density-driven particle sedimentation.
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.
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.
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.
During the CROZEX study, the silicon budget was relatively well constrained in terms of stocks and fluxes. ... Lithogenic particles can be a potential source of silicon to the silicon...
