Sub-bottom Profiling – Overview

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.

Applied Acoustics manufactures a variety of sub-bottom profiling systems to accommodate different challenges such as coastal or deep waters, soft sediment or harder rock. The component system configuration allows the optimum package to be tailored to the particular application.

A typical sub-bottom profiling system will consist of;

  • Energy Source
  • Sound Source
  • High Voltage Cable
  • Hydrophones
  • Acquisition system
