The ecological significance of sulfur in the energy dynamics of salt marsh and coastal marine sediments [link]Paper  doi  abstract   bibtex   
Sulfur is an important element in the metabolism of salt marshes and subtidal, coastal marine sediments because of its role as an electron acceptor, carrier, and donor. Sulfate is the major electron acceptor for respiration in anoxic marine sediments. Anoxic respiration becomes increasingly important in sediments as total respiration increases, and so sulfate reduction accounts for a higher percentage of total sediment respiration in sediments where total respiration is greater. Thus, sulfate accounts for 25% of total sediment respiration in nearshore sediments (200 m water depth or less) where total respiration rates are 0.1 to 0.3gCm1 day1 , for 50% to 70% in nearshore sediments with higher rates of total respiration (0.3 to 3gCm2 day1), and for 70% to 90% in salt marsh sediments where total sediment respiration rates are 2.5 to 5.5gcm2 day1 .
