    Methane hydrates form under the sea floor through bacteria converting dead organic matter.  Mostly plankton, the matter is buried for millions of years.

    The formation of methane spewing vents that are found under the ocean’s floor still remain a mystery to scientists. Under all the world’s oceans, Methane clathrate, a solid form of methane gas mixed with ice and water are formed in deep pockets under ocean sediment. Scientists once thought these only existed in the cold depths of space. It is thought that the volcanic activity under the Earth’s crust coupled with restless fault lines create the conditions needed to convert the methane gas found in the deep ocean into Methane clathrate and then released into the water.
