InnomarModel 100 -Medium Sub-Bottom Profiler (SBP)

SHARE

The "Innomar medium-100" parametric sub-bottom profiler is designed for offshore applications down to 2,000m water depth. The transducer can be either mounted over-the-side or in the hull. This SBP model acquires full-waveform data (24 bit) that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the Innomar SBP data.
