Because methane is a hydrocarbon, the icy hydrate deposits are an important part of the carbon cycle, accounting for billions of tons — up to 22% — of Earth’s organic carbon. The methane feeding this layer… Continue Reading Making Methane from Microbes: UTIG and UT Knoxville Hunt for Biological Source of Fiery Ice
