Marine Gas hydrate research: Changing views over the past 25 years
During the past quarter century views have changed in marine gas-hydrate research and in its perception by the society at large: (1) Deep-sea drilling has gone from a policy of avoiding gas hydrate to emphasizing deliberate drilling for it. (2) International programs have evolved from exploiting gas...

During the third stage, in further exploring global methane hydrate reserves, it has become evident that environmental changes over the past decades may have triggered release of methane from destabilizing hydrate at the seabed as well as diminished oxygen content in the near-bottom of marginal seas.
