Sub Bottom Profiling (SBP)

Sub-Bottom Profiling (SBP) is a subsurface sensing technique by using a special tool that utilizes acoustic waves with single channel to display the shallow seabed seismic profile (JD Penrose et al, 2005). SBP method is one application of seismic reflection method for identifying the sediment layers beneath the surface of the seabed.

Sound source (transmitter) emits a signal propagates downward through the water column and then the receiver will receive the signal back after reflected by the surface of the seabed and the boundary layer below the surface of the seabed.
