摘要: Abstract Based on the interpretation of 3D seismic profiles, shallow sediments consist five units. BSRs and acoustic blanking are located within gas-hydrate stability zone as indicators for presence gas hydrate. Seismic-attribute analysis shows that if hydrates underlain by free gas, high reflection strength low instantaneous frequency displayed below BSR. Whereas, not, is continuously high. Four models occurrence hydrate suggested, considering slope sedimentary layers well or gas.
