Seasonal formation of oxygen-depleted water masses in bottom environments is a widespread phenomenon in coastal areas around the world.Dissolved oxygen (DO) depletion in bottom water is lethal to macrobenthic animals and eliminates sensitive species, while hypoxic conditions would enhance microbial heterotrophic activity and hence diversion of energy-flow into the microbial food web.In general, microbial respiration is responsible for the depletion of DO, and its availability in turn exerts fund
