Abstract
In this study, analyses of a high-resolution, 3D seismic reflection dataset covering an area of 950km2 was used to characterise and understand interactions between submarine channels and seafloor morphology in the deep-water western Niger Delta. The seafloor bathymetry of the study area revealed the presence of submarine channels, fault scars, pockmarks, and a shale-cored anticlinal fold structure. In terms of geometry, the channels were crescent-shaped, with low-angle gentle dipping walls and characterised by moderate to high-amplitude, discontinuous to continuous seismic reflections. The channels were observed to follow topographic lows, trending downflow, NW-SE of the study area. A major low sinuosity (<1.10) channel of about 15.4km long, with a vertical relief of over 200.0m to the channel floor traversed the study area. Although no evidence of seabed incision and erosion of this major channel, there is tendency for channel deflection away from the seafloor relief due to the growth of anticlines above the toe-thrusts in the area which could result in an increase in channel width and more accommodation space for sediment deposition.

Key words: Niger Delta, Seafloor morphology; Submarine channels, 3D Seismic.
