Figure 1

(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. [23] 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 [26].
