Innomar "medium-100" Sub-Bottom Profiler
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.
The Innomar medium-100 SBP 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.
Application examples are given in the Deep Water Applications section.
The first generation of this SBP model was introduced in 2004 ("SES-2000 medium"), while the latest generation has been launched in 2020.
