Cas No 74-82-8 Organic Gases Ch4 , Liquefied Compressed Gas for Glass Making
Description:
Methane is essentially insoluble in water, but it can be trapped in ice forming a similar solid. Significant deposits of methane clathrate have been found under sediments on the ocean floors of Earth at large depths.
Estimates consider up to 15,000 gigatonnes of carbon may be stored in the form of clathrates (hydrates) in the ocean floor, not accounting for abiotic methane, a relatively newly discovered source of methane, formed below the ocean floor, in the earth crust. It has been suggested, that today's methane emission regime from the ocean floor, is potentially similar to that during the PETM.
Arctic methane release from permafrost and methane clathrates is an expected consequence and further cause of global warming.
