The sub-bottom profiling instruments are among the tools of marine investigations, available to geophysicists to analyse the seabed, and study the subbottom stratigraphy of marine deposits.

 Main advantages and uses :

  • continuous mapping of the sub-bottom sediment layers
  • top bedrock detection
  • pipeline detections

In the oceanographic seismics researches, sparker and boomer profiles give high resolution images of oceanic structures and water column.

  • water column analysis

 It is a cost effective method in seabed research programs and civil planning works. Seismic surveys can cover a wide area. Correlation with sea-bed determination can be then done ponctually by drilling methods.


The marine seismic instruments of SIG France are recognized worldwide by

  • marine institutes,
  • national geological surveys,
  • universities geoscience departments, 
  • offshore geophysical survey companies,
  • oceanographic research institutes.
