SES-2000 deep Sub-Bottom Profiler
The SES-2000 deep parametric sub-bottom profiler is designed for offshore applications down to 6,000m water depth. Based on the SES-2000 medium model this model uses lower primary frequencies to achieve extended range and penetration.
SES-2000 deep systems are able to acquire full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides it's ISE post-processing software specialized on the SES-2000 data.

(range 3,600–4,040m; sediment penetration about 100m; frequency 4kHz).
Some more data examples are shown in the Deep Water Applications section.
