The characteristics and formation of the submarine topography in the Liaodong Bay,the Bohai Sea

The Liaodong Bay of the Bohai,rich in oil,has been investigated by a large number of geologists,but most of research was focus on structural geology.Through the survey by single beam echo-sounder system,the submarine topography of the Liaodong Bay was studied.Topographical features of the seabed topography in the Liaodong Bay were divided into five sub-zones,and factors affecting the development of terrain in the Liaodong Bay were also discussed.The formation of topography in the Liaodong Bay is affected by structural geology condi-tion,hydrodynamic condition,and sediment supply.
