| Abstract: | The data have been used to understand the variations of chemical features (distribution of nutrients, oxygen and sulfide) at specific density surfaces of the western Black Sea. The range and possible reasons of variations in the vertical profiles of nutrients, oxygen and hydrogen sulphide concentrations are discussed for the Black Sea. The concentrations of inorganic nutrients in the productive surface waters ranged between 0.02-0.30 μM for o.PO4-P and 0.10-0.50 μM for the TNOx-N. The maximum TNOx value of 6.5-7.0 μM was found between the σθ = 15.35-15.55 surfaces throughout the basin. The upper and the deeper phosphate maxima were observed at σθ = 15.50-15.60 and σθ = 16.20-16.25 surfaces, respectively. TNOx/PO4 ratios displayed distinct maxima at specific density surfaces of the upper nutricline. Si/TNOx and Si/PO4 were also calculated in the western Black Sea. |
