Hydrates are typically found where organic carbon accumulates rapidly, mainly in continental shelves and enclosed seas. These are biogenic hydrates (containing CH4, formed from bacterial methanogenesis).

Muller and Suess (1979) demonstrated the influence of sedimentation rate on organic carbon accumulation under oxic open-ocean conditions. They found that the organic carbon content of marine sediments increases by a factor of about two for every tenfold increase in sedimentation rate. The underlying mechanism was believed to be the more rapid removal and protection of organic matter from oxic respiration and benthic digestion at the sediment/water interface by increasingly rapid burial (cf Sect. 12.3.3). Also... 

It should be apparent that the model for organic carbon accumulation as shown by these two equations is not adequate to describe the complete process. 

Discuss the role of sea-level rise on marsh accretion and organic carbon accumulation. 

It was found that both sediment and organic carbon accumulation rates are the highest in the inner shelf area (1.8 g C/(cm -yr) and 3.1 mg C/(cm -yr) for sediment and organic carbon accumulation rates, respectively). Sediment accumulation rates decreased offshore, whereas organic carbon accumulation...
