New Progress in Marine Gas Hydrates: Summary from 2006 Western Pacific Geophysics Meeting

2006 Western Pacific Geophysics Meeting was held by American Geophysical Union, and there were thousands of scientists from all over the world attending to this meeting. According to the reports that were published during the meeting, we can see that gas hydrate is still one of the most attractive research areas in the world. Gas hydrate researches released on the meeting are summarized and can be divided into five aspects: hydrate exploration methods, characteristics of seafloor environment where hydrates exist, physical properties of gas hydrates, evaluation and exploitation plans and simulated experiments. In the exploration field, 3D seismic survey, magnetic features of sediments and geochemical methods are widely used. Seafloor investigations include researches on gas hydrate venting, geological structures of landslides in hydrate zone and sediment granulometry on hydrate ridge. There are many thermodynamic and kinetics researches on hydrates as well. Simulated experiments as a safe and economic method also make a great contribution to the hydrate researches, and some feasible methods on hydrates exploration and exploitation were tested by experiments. In the end, we predicted some potential areas of hydrates which may be the new hot spots in future.
