Gas hydrates and methane seeps
Scope
Gas hydrate Session invites both ambitious scientific papers on the growth and evolution of surface-type gas hydrates, environmental impact of methane seeps, and geologic factors to develop deep-seated gas hydrate deposits, and scientific and technical reports on advances and prospects of the national MH project, based on the recent expeditions and experiments on gas hydrates and related phenomena.
