Geophysical Indicators of Gas Hydrate in the Northern Continental Margin, South China Sea
(a) Areas of gas hydrate exploration in the northern part of the South China Sea and the gas hydrate drilling zone of Shenhu area, Baiyun sag; (b) Bathymetric map of Baiyun sage that was interpolated by the 2D seismic data in this area. Modern canyons shown by Zhu et al.  were also identified. Black lines and white line show seismic line A, line B, and line C used in the paper. The zones surrounded by broken yellow lines show the BSR on the seismic lines and in the gas hydrate drilling zone in 2007 .
