  rdf:value "Combinaciones naturales de gas natural y agua, parecidas al hielo, que tienen el potencial de proporcionar una gran fuente de gas natural proveniente de los océanos y las regiones polares del mundo. Son conocidos por estar ampliamente distribuidos en regiones de permahielo y bajo el mar, en sedimentos de los márgenes continentales externos. Por lo general es aceptado que el volumen de gas natural contenido en las acumulaciones de hidrato de gas del mundo excede en gran medida el de las reservas de gas conocidas."@es, "Naturally occurring \"ice-like\" combinations of natural gas and water that have the potential to provide an immense resource of natural gas from the world's oceans and polar regions. Gas hydrates are known to be widespread in permafrost regions and beneath the sea in sediments of outer continental margins. It is generally accepted that the volume of natural gas contained in the world's gas hydrate accumulations greatly exceeds that of known gas reserves."@en ;
