Sub-bottom profiling systems from Applied Acoustics use the technique of Reflection Seismology to create a 2D picture of the geology beneath the seabed. This technology requires a controlled seismic source of energy (a CSP unit) connected by high voltage cable to a sound source (boomer or sparker) that transfers the energy through the water to penetrate the seabed. The energy reflected back from the solid seabed layers is received by hydrophones on the sea surface, recorded and processed by a data acquisition system aboard a vessel, so that visual profile of the seabed can be created.
