SES-2000 medium Sub-Bottom Profiler
The SES-2000 medium parametric sub-bottom profiler is designed for offshore applications down to 2,000m water depth.
This model is based on the SES-2000 standard SBP with additional transceivers to achieve extended range and penetration.
SES-2000 medium sub-bottom profilers are able to acquire full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the SES-2000 data.
SES-2000 medium parametric sub-bottom profiler echoprint data example in deep water
(range 2,160–2,250m; sediment penetration about 30m; frequency 5kHz).
Some more data examples are shown in the Deep Water Applications section.
