Signal Processing in Ocean Bottom Seismographs for Refraction Seismology
| Instrumentation Viewpoint
This communication presents some experimental results on wavelet techniques applied to seismic signal processing. These Techniques, which have been used to process seismic signals will now be applied to refraction seismology. The Ocean Bottom Seismometer, OBS, represents the achievement of a joint effort by teams from different scientific
and technological disciplines such as electronics, mechanics, acoustics, communications, information technology, marine
geophysics, etc. This easy- to- handle and sophisticated equipment not only allows useful active and passive seismicity
information to be recorded but also permits the recording of other wave fronts, with multiple applications to marine
environment research.
