"Innomar light" SBP
The "Innomar light" parametric sub-bottom profiler is designed for shallow-water applications inshore and near-shore at water depths down to 400 meters.
This model acquires 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 Innomar SBP data.
