Energy in the form of electricity can be harvested from marine sediments by placing a graphite
electrode (the anode) in the anoxic zone and connecting it to a graphite cathode in the …

The oxidation of organic matter coupled to the reduction of Fe(III) or Mn(IV) is one of the
most important biogeochemical reactions in aquatic sediments, soils, and groundwater. This …
