Quantitative Role of AOM

8 or if transient eonditions prevail in the pore water system (Hensen et al. 2003 Kasten et al. 

Reeburgh et al. (1993) estimated the global methane flux in marine sediments to a mean value of 70 Tg yr or 0.5 10 mol CH yr. This is equivalent to 2% of the entire organie earbon mineralization via oxygen respiration and about 7% of the global sulfate reduetion. A more recent estimate by Hinriehs and Boetius (2002) of AOM
