摘要
As a new energy source, gas hydrate has shown important economic significance. Although the total mass remains unclear, it is consensus that the gas hydrate is a major hydrocarbon reservoir in Earth＇s surface （Milkov, 2004）. Bottom-simulating reflector （BSR） on seismic profiles is a main means to identify the gas-hydrate deposits in current surveys. However, scientific drilling indicated BSR did not be found in some of sea area, where collected gas hydrate. BSR is neither the best nor only indicator for the presence of gas hydrates. Thus, more or comprehensive means are need to identify the gas hydrate accurately in the ocean.
