Seismoacoustic profiling

Seismoacoustic profiling is a type of geophysical survey based on the same rules and laws of physics as reflection seismology. The basic difference between land and marine surveys is that the entire equipment set (the source of impulses and receivers: hydrophones), is towed behind a vessel in a continuous way. Seismoacoustic methods are characterised by :

  • high signal frequency,
  • low signal energy,
  • short repetition time (intervals between successive sounding impulses).

Basically, the single-channel recording equipment is used. For many years, the only way of recording these data was the direct recording of results on special recording paper. The GEOECHO database was developed to offer access to these data in a digital form.
