The variability of benthic fluxes and sedimentary remineralization rates in response to seasonally variable organic carbon rain rates in the deep sea; a modeling study Academic Article uri icon

abstract

  • While observed seasonal variability in benthic O sub(2) fluxes is consistent with observed variability in organic carbon rain rates, the amplitude of the seasonal benthic flux signal is strongly damped by the presence of organic matter which degrades too slowly to produce seasonal signals. For most pelagic sediments, bioturbation is not rapid enough to bury the most labile fraction of the organic carbon rain significantly before it is degraded; thus, seasonal variability in pore water O sub(2) and nutrient profiles is unlikely.
