To settle the issue, Ward and Babbin decided to look at exactly what was going on in anoxic ocean water when bacteria were given nitrogen and other nutrients to chew on. (sciencedaily.com)
This geographic distribution of anoxic conditions points towards the importance of paleogeography, basin restriction, and nutrient fluxes as key controls on the occurrence of extreme deoxygenation. (royalsociety.org)
This inhibits oxidation of CH4 since methanotrophic bacteria responsible for this process can not function in anoxic conditions normally found in waterlogged land. (skepticalscience.com)
