Applications / User Benefits

Innomar's narrow beam parametric sub-bottom profilers are used worldwide for many tasks and applications during marine explorations and investigations:

  • Geological and geophysical explorations
  • Sediment investigation campaigns for dredging projects
  • Route surveys for pipeline and cable laying projects
  • Search for mineral resources
  • Surveys in small and (ultra) shallow waters, harbours, flood gates, shore zones
  • Search for objects like wrecks, pipelines, sea cables, navigation obstacles, boulders
  • Archaeological investigations for wrecks, historical buildings and settlements
  • Water column imaging / gas seepage monitoring


Advantages of Parametric SBP / User Benefits

Using nonlinear acoustics for sub-bottom profiling gives the following advantages compared to linear sound generation:

  • Narrow sound beams at low frequencies with small and portable transducers, the half-power beam width is nearly the same for all generated frequencies.
  • There are no side lobes for the low-frequent sound beam during transmission.
  • Very short sound pings without significant ringing effects can be transmitted.
  • Detection of sediment layers and objects with high resolution plus accurate water depth determination due to high-frequent channel of primary frequencies.
  • Good sediment penetration (depending on material, water depth, frequency and environmental conditions).
  • Mobile systems with user-friendly control software for the employment on small ships, usable also in shallow waters and in complicated areas.
  • Digitally stored data with excellent, reliable results with online data analysis and extended post processing capabilities.
