Re-assessing the significance of nutrient cycling by the marine pelagic and sympagic microbial community based on nitrogen and silicon isotope dynamics (FWOTM703)

Carbon fixation and resulting sinking of organic matter pumps out inorganic carbon as well as a suite of nutrients such as nitrogen and silicon from surface waters. Bacterial decomposition in the deep ocean remineralizes these nutrients back to their inorganic forms. Therefore, low nutrient concentrations prevail in surface ocean, limiting production there, while high concentrations prevail in deep ocean.
