Sulfate reduction and sulfide accumulation

Sulfate reduction rates in the deep basin sediments of the Saguenay Fjord are relatively low in comparison to other coastal environments (32 nmol cm-2 d-1 integrated over the top 30 cm), and the pore water is only weakly depleted in sulfate. Sulfate reduction is more intense, however, in the rapidly accumulating 

The conditions required for pyrite formation (reduction of sulfate and availability of reactive iron phases) exist in the Saguenay Fjord. Indeed, the high
