This article describes recent work on marine hydrates off western Canada. Natural occurrences of gas hydrates have been reported in the geoscience literature since the early 1970s. Gas hydrates are solid ice-like structures in which gas molecules (largely methane) are trapped within cages of water molecules. Some 50 regions of hydrate occurrence have been reported in marine, permafrost, and lake environments worldwide. Interest in gas hydrates is due to the fact that the total amount of hydrocarbons locked up in them probably exceeds other known fossil hydrocarbon resources.

Gas hydrates contain large concentrations of methane. The stability of natural gas...
