... of homogeneous layering below the water bottom. However, in some shallow water ocean-bottom node (OBN) data, the complex seabed topography and significant velocity changes near the seabed caused by complex sediments (such as mud volcano) that could affect the subsurface imaging and structural interpretation...

... Pleistocene. Occurrence of mud volcano in the concession indicates the faults are still active. For the first time, this study gives systematic illustration on the fault pattern and structure configuration of the east Apsheron Sill in terms of good image OBN seismic. The enhancement in structure feature...
