Study finds massive flux of gas, in addition to liquid oil, at BP well blowout in Gulf:
"A new University of Georgia study that is the first to examine comprehensively the magnitude of hydrocarbon gases released during the Deepwater Horizon Gulf of Mexico oil discharge has found that up to 500,000 tons of gaseous hydrocarbons were emitted into the deep ocean.
The authors conclude that such a large gas discharge—which generated concentrations 75,000 times the norm—could result in small-scale zones of 'extensive and persistent depletion of oxygen' as microbial processes degrade the gaseous hydrocarbons.
