SES-2000 medium-100 Sub-Bottom Profiler
The SES-2000 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 SES-2000 medium-100 SBP 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 SES-2000 data.
Application examples are given in the Deep Water Applications section.
This model is available in a new version with reduced weigth and size to improve handling for mobile installations. We will show the new version at our user workshop in November 2015.
