May 2009AbstractAnoxic conditions are a natural feature of numerous areas in coastal and marginal seas. Theseconditions arise, when transport rates of organic matter and oxygen in to deeper layers of thecoastal seas do not balance and oxygen is used up leaving an excess of organic material tobe decomposed. The decomposition processes are continued by bacterial activity employingother electron acceptors than oxygen and usually end up with sulphate (a major constituentin seawater) reduction. This process leads to the production of hydrogen sulfide as one ofend product, which is toxic to higher life forms.
