Dissimilatory sulfate reduction can be described by the following net eqnation  

Continental margin sediments play a major role for the overall budget of the global carbon cycle in the modern ocean. Most bnrial of organic carbon takes place on the continental shelf, in particnlar in deltaic and other coastal sediments (Berner 1982 Hedges and Keil 1995). Thns, 82% of the bnried organic carbon is stored in shelf sediments 

25-50% of the mineralization (Jorgensen 1982). The relative importance of sulfate reduction drops to 1% as we move down the continental slope and it
