Biogeochemical Peculiarities of the Vertical Distributions of Nutrients in the Black Sea

摘要: Analysis of the vertical distributions ratios between C, S, Si, N, and P revealed layers with significant systematic differences from theoretical Redfield Richards values. These anomalies can testify to presence such processes as denitrification/anammox “phosphate dipole” formation. Based on which concentrations do not change under redox conditions variability, we estimated numerically other elements deficiencies rates that form these deficiencies. The calculated (0.012–0.046 μM per day) correspond well present observations data. possible controlling shallower phosphate minimum formation equal 0.008–0.032 day, deeper are in range 0.006–0.024 day. Ct/St ratio showed bacterial sulfate reduction was only process anaerobic mineralization organic matter anoxic zone Black Sea lead a constant stoichiometric C/S close one 2.
