Study Looks for Methane From Deepwater Horizon Spill
by dailyfusion in The Daily Fusion
The 2010 Deepwater Horizon blowout discharged roughly five million barrels of oil and up to 500,000 tons of natural gas into Gulf of Mexico offshore waters over a period of 84 days. In the face of a seemingly insurmountable cleanup effort, many were relieved by reports following the disaster that naturally-occurring microbes had consumed much of the gas and oil.... Read more »

The joker who brought climate science out of the cold
by Andy Extance in Simple Climate

Georgia Tech Helps Study of Gas Hydrates as a New Energy Source
by dailyfusion in The Daily Fusion
Scientists from Georgia Institute of Technology have developed innovative tools for studying methane hydrate samples found under sediments on the ocean floors. An international team of scientists have recently used thouse tools in a groundbreaking research of natural gas hydrates and their potential usage as an energy source. The worldwide amount of carbon bound in gas hydrates is conservatively estimated to total twice the amount of carbon to be found in all known fossil fuels on Earth.... Read more »
