Definition / notes:	Gas hydrates occur abundantly in nature, both in Arctic regions and in marine sediments. Gas hydrate is a crystalline solid consisting of gas molecules, usually methane, each surrounded by a cage of water molecules. It looks very much like water ice. Methane hydrate is stable in ocean floor sediments at water depths greater than 300 meters, and where it occurs, it is known to cement loose sediments in a surface layer several hundred meters thick. http://marine.usgs.gov/fact-sheets/gas-hydrates/title.html . Selon certaines statistiques, il y a plus de méthane gelé que toutes les ressources d'hydrocarbures et de gaz naturel réunies dans le monde. La recherche dans le Nord est très prometteuse, et nous accroissons certainement nos efforts dans ce secteur. Le meilleur projet dans le monde en matière de méthane gelé se trouve dans le nord du Canada. http://www.parl.gc.ca/37/3/parlbus/chambus/house/debates/009_2004-02-12/han009_1205-F.htm
