The few dissolved sulfates that wash in are consumed by chemical reactions that occur within the chemocline, the thin layer of water that separates the oxygenated surface waters from the anoxic depths.
Sulfur-oxidizing epibacteria have been found on nematodes living in marine sands, at the oxic-anoxic interface; the nematodes appear to derive their nutrition by feeding directly on their symbionts, and they track the chemocline (chemical gradient in the water column) to provide their symbionts with both sulfide and oxygen.
